They often have a dark head, thorax and wing pads and the distal portion of the abdomen is usually dark green. Several species of aphids are commonly found on citrus. : orange, mandarin, tangerine, clementine, grapefruit, pomelo, lemon and lime, Postharvest Biology and Technology of Tropical and Subtropical Fruits: Açai to Citrus, Postharvest Biology and Technology of Tropical and Subtropical Fruits: Mangosteen to White Sapote, Mechanism of action of Bacillus thuringiensis insecticidal toxins and their use in the control of insect pests, The Comprehensive Sourcebook of Bacterial Protein Toxins (Fourth Edition), Microbial Control of Mite and Insect Pests of Greenhouse Crops. The average number of beetles on resistant and susceptible plants varied between 0 and 2.75. However, populations do not usually reach treatable levels until later in the growing season, following insecticide applications for other pests (Johnson et al., 1996). Aphis gossypii is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera. It is common in North and South America, Central Asia, Africa, Australia,[3] Brazil, East Indies, Mexico and Hawaii and in most of Europe. A. gossypii has a wide host range, including cotton, cucurbits, and many other legumes. It also affects citrus, cotton and hibiscus. The following relationships have been collated from the published literature (see 'References'). There is often a great deal of leaf curling and distortion which hinders efficient photosynthesis. However, the accumulation of honeydew in arid regions such as the southwestern United States can result in sticky cotton. The cotton-melon aphid, Aphis gossypii Glover, is a polyphagous species with a worldwide distribution. Wraight, ... M. Faria, in Microbial Control of Insect and Mite Pests, 2017. It is relatively insensitive to the Khamsinwinds prevalent during spring in the Middle East and may be dispersed by them. Aphidinae: Aphidini. The population dynamics, development of gonads, takeoff and flight behaviour of Aphis gossypii Glover were investigated in order to test whether there was variation of migratory ability in the spring population. The Vip1/Vip2 binary toxins, of 100 kDa and 52 kDa, respectively, act together to kill insect pests such as the cotton aphid Aphis gossypii and corn rootworm Diabrotica virgifera [38]. A. gossypii has a worldwide distribution, although in arctic regions it is mostly confined to glasshouses. A study on the distribution pattern of Aphis gossypii Glover and its coccinellid predator, Menochilus sexmaculatus Fabricius, was conducted in a chilli ecosystem at the experimental field of Universiti Putra Malaysia. Initial infestations of cotton aphid, Aphis gossypii Glover, occur between the seedling and early reproductive stages of cotton (Slosser et al., 1989). However PRSV persists only few hours on the stylets: therefore long-distance spread by aphids is limited. The structure of Vip1A is not known, but a region with alternating hydrophobic and hydrophilic residues within this protein was identified, and it was proposed that it could adopt a structure of a β-strand that would be important for membrane penetration forming a β-barrel necessary for translocation of the Vip2A component, similar to other bacterial toxins such as protective antigen (PA) of anthrax toxin from B. anthracis, the Iota Ib toxin from C. perfringens, and the C2-II toxin from Clostridium botulinum [40]. Economic damage due to A. gossypii is by direct feeding, the excretion of honeydew and virus transmission. It is important to use appropriate rootstocks that ensure a certain tolerance or resistance of the variety/rootstock combination. Its head and thorax are black, the abdomen yellowish-green with black lateral spots and the antennae are longer than those of the apterous female. This interferes with harvest and reduces lint quality. The ADP-ribosylating activity was masked in the plant cell, but the propeptide could be cleaved by the proteases present in the midgut of larvae, recovering the insecticidal activity [41]. In general, cotton aphid populations are maintained below treatable levels by the actions of natural enemies unless sprays targeting other pests have been made that disrupt the natural enemy complex (Weathersbee and Hardee, 1994). The study had revealed that distribution of M.sexmaculatus positively correlated with its prey distribution. It thrives outdoors in southern Europe but survives only under glass in northern Europe. [4], The adults and nymphs of the cotton aphid feed on the underside of leaves or on the growing tips of shoots, sucking juices from the plant. In a previous study on chrysanthemum, Davies et al. In the United States, it is a regular a pest in the southeast and southwest, but is occasionally damaging everywhere. Females continue to produce offspring without mating so long as the weather is favourable for feeding and growth. Only resistance against fruit fly (Decus cucurbitae Coll. was controlled by a single recessive gene. The main impact of these insects is that they transmit viral diseases as they feed and move from sweetpotato plant to plant in the field. Diagnosis. In the United States, it is a regular a pest in the southeast and southwest, but is occasionally damaging everywhere. & Roff, M.N.M. Aphis gossypii does not have a sexual phase in the tropics, nor in most of Europe. The vertical and temporal distribution of an aphid, Aphis gossypii Glover, and the coccinellid populations on six chilli varieties were studied. Melon aphid occurs in tropical and temperate regions throughout the world except northernmost areas. Order Homoptera—Aphids, Leaf- and Planthoppers, Psyllids and Whiteflies, Microbial Control of Insect and Mite Pests of Cotton, Microbial Control of Insect and Mite Pests, Citrus spp. The 3D structure and PDB accession number are shown here, with the structure alignment with the NAD-dependent ADP-ribosyltransferase domain of the Iota toxin from C. perfringens (performed with the jFAT-CAT algorithm). There is no report of PRSV-P or -W seed transmission. Abstract. Its origin is in Europe. A propeptide sequence was added at the C-terminal end of Vip2A toxin. Because melon aphid sometimes overwinters in greenhouses, and may be introduced into the field with transplants in the spring, it has potential to be damaging almost anywhere. Insecticide sprays targeting cotton aphid occur in most regions, especially in arid regions to preserve lint quality and improve milling quality. Introduction to Aphis gossypii: scientific and common names, protected status (red lists, regulations), biological status in France, historical and contemporary. These oligomers insert into the membrane, forming pores with high conductance in the black lipid bilayer [40]. The Vip1A forms sodium dodecyl sulfate (SDS)–resistant and heat-sensitive oligomeric structures in solution [40]. The mean threshold for developmentis estimated at 6.2ºC; generational time is 4.5 days at the optimal temperature of … Aphis gossypii is considered as an important vector of chilli veinal mottle potyvirus (CVMV) and cucumber mosaic cucumovirus (CMV) in Malaysia. In plants which produce the phytoestrogen coumestrol, such as alfalfa, damage by aphids is … The most important aphid-transmitted virus is sweetpotato feathery mottle virus. To solve this problem, a Vip2 zymogen with lower actin-ADP-ribosylating activity than the wild type was constructed using protein engineering with a proper extension of the polypeptide chain. [1] The nymphs vary in colour, being shades of green, tan and gray. Variable watermelon populations resistant to cucumber beetle (D. balteata Lec. Small to medium sized aphids. Several members of the Aphidiinae and Aphelinidae wasp families are parasitoids of aphids. PRSV is acquired and transmitted during very short probes, what makes its spread within a field generally rapid. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. pp. We examined the effect of fertilization on population growth and within-plant distribution of melon or cotton aphid, Aphis gossypii Glover, on potted chrysanthemum, Dendranthema grandiflora (Tzvelev). In general, cotton aphid is an indirect pest that feeds on the underside of leaves and can produce large amounts of honeydew. Resistance to red pumpkin beetle (Af) was dominant to susceptibility.102, M. El-Otmani, ... L. Zacarías, in Postharvest Biology and Technology of Tropical and Subtropical Fruits: Açai to Citrus, 2011. The juvenile forms are almost always yellowish in color. ), cucumber beetle (Diabrotica balteata Lec. Journal of Asia Pacific Entomology 5, 185 – 191. Interactions where Aphis gossypii is the victim or passive partner (and generally loses out from the process) . In the United States, it is regularly a pest in the southeast and southwest, but is occasionally damaging everywhere. [4], In the southern half of the US, as far north as Arkansas, sexual reproduction of the cotton aphid is not important. It is cosmopolitan in habitat. There is considerable debate about the pest status of cotton aphid and its impact on cotton yields. Similar toxins were reported in B. cereus sharing 95% identity and showing insecticidal activity against the Coleopteran D. virgifera [39]. They cause damage by sucking sap, thus weakening the plants, and by excreting a sticky honeydew that grows into a sootylike mold on leaves that makes plants unable to carry out photosynthetic activities. In terms of pest management implications, we also investigated the effect of fertilization on the number of insecticide The legs are yellow, as are the antennae which are three quarters of the length of the body. Long-distance spread may occur through the movement of infected material (seedlings, fruits). Classification. The control of aphids is not an easy task, as they have multiple hosts besides citrus. From: Current Opinion in Insect Science, 2014, Ambayeba Muimba-Kankolongo, in Food Crop Production by Smallholder Farmers in Southern Africa, 2018. Apterae very variable in colour, large specimens dark green, almost black, but adults produced in crowded colonies at high temperature may be less than 1 mm long and very pale yellow to almost white. In general, insect damage may be more severe in locations that are dry or have low rainfall. Among cucurbit vegetables, it can seriously affect watermelons, cucumbers, cantaloupes, squash and pumpkin. Aphis (Aphis) gossypii Glover, 1877: UKSI Synonym Source; Aphis gossypii Glover, 1877 synonym: UKSI Classification unranked Biota kingdom Animalia phylum Arthropoda subphylum Hexapoda class Insecta order Hemiptera family Aphididae genus Aphis species Aphis gossypii. Figure 30.5. It is not known where this species originated, but it is now found in tropical and temperate regions throughout the world except extreme northern areas. As melon aphid occasionally overwinters in greenhouses, and may be introduced into the field with transplants in the spring, it has potential to be damaging almost anywhere. USSR), Austria, Azores, Belgium, Britain, Bulgaria, Czechoslovakia, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Malta, Netherlands, Norway, Poland, Portugal, Romania, Sardinia, Sicily, Spain, Sweden, Switzerland, Yugoslavia, ASIA (excl. Morphometric variation of A. gossypii … During heavy infestations, plant vigor is greatly reduced. Winged aphids may travel long distances and introduce viruses into new areas. A Manual of the Insects of the Hawaiian Islands, including Enumeration of the Species and Notes on Their Origin, Distribution, Hosts, Parasites, etc. sexmaculatus positively correlated with its prey distribution. The life span of a parthenogenic female is about twenty days in which time it can produce up to 85 nymphs. A. gossypii has a worldwide distribution, although in arctic regions it is mostly confined to glasshouses. The cotton aphid, Aphis gossypii (Hemiptera: Aphididae), is a serious pest of Malváceae in the northeastern Brasil. (2002) Vertical and temporal distribution of Aphis gossypii Glover and coccinellid populations on different chilli (Capsicum annuum) varieties. [3], The wingless female cotton aphid has an ovoid body about two millimetres long in varying shades of green. [1], Carbamates and organophosphates are commonly used against A. gossypii around the world. The aphids are a vector of crinkle, mosaic, rosette, CTV and other virus diseases. Hide Fungi Hide Ascomycete Fungi Hide Basidiomycete Fungi Hide Fungoids The cotton aphids (Aphis gossypii), which are about 1–1.5 mm long, constitute the major pest of okra in Southern Africa. [3], Predators include midges, lacewings, syrphid fly larvae, anthocorid bugs and ladybirds (ladybeetles). They damage sweetpotato plants by sucking sap from growing shoots causing wrinkling, cupping, and downward curling of young leaves. Melon aphid occurs in tropical and temperate regions throughout the world except northernmost areas. This disease causes the death of infected trees. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. Life Cycle: Aphis gossypiiis viviparousthroughout the year. [1] In Russia various wild plants are hosts to the overwintering eggs. Worldwide: cosmopolitan, everywhere host plantsare grown. (2004) showed that leaf nitrogen is higher in young and physiologically mature leaves than older, basal leaves. Reproduction in these pests is largely asexual, and development is rapid, leading to explosive population increases. PRSV is transmitted in a non-persistent manner by more than 24 aphid species among which Aphis gossypii, Myzus persicae and A. craccivora are the most efficient. Cécile Desbiez, Hervé Lecoq, in Reference Module in Life Sciences, 2020. A new distribution map is provided for Aphis gossypii Glover (Doralis frangulae[Aphis frangulae] Kalt., Cerosipha gossypii[Aphis gossypii] (Glov.)) The three-dimensional (3D) structure of Vip2A (PDB 1QS1) is similar to nicotinamide adenine dinucleotide (NAD)–dependent ADP-ribosyltransferase of other bacterial toxins, such as Iota toxin from C. perfringens and C2 toxin from C. botulinum (Figure 30.5). Population growth rates and within-plant distributions of Aphis gossypii Glover and Myzus persicae (Sulzer) were studied on potted chrysanthemums, Dendranthema Grandiflora Tzvelev. management strategy. Reproduced from Varela, A.M., ICIPE, Infonet-Biovision. In addition, aphids transmit the yellow vein mosaic virus in okra.. John L. Capinera, in Handbook of Vegetable Pests, 2001, Melon aphid is widely distributed, and is known from tropical and temperate regions throughout the world except northern Canada and northern Asia. Idris, A.B. Biology & Ecology: Life cycle. Pest outbreaks can also be prevented by the elimination of weeds that favor pests development and mites can be reduced by pruning affected leaves. Resistance to fruit fly was controlled by a single dominant gene Fwr.39 Chambliss and Cuthberg5 found that resistance to Diabrotica balteata Lec. (Hemipt. Because melon aphid sometimes overwinters in greenhouses, and may be introduced into the field with transplants in the spring, it has potential to be damaging almost anywhere. In the United States, it is regularly a pest in the southeast and southwest, but is occasionally damaging everywhere. However, the expression of these toxins severely affected the plant development, killing the plant [41]. Noni monocultures favor pest outbreaks; thus, the severity and frequency of pest attacks can be minimized by intercropping with other species of non-host plants. Due to their specific activity against D. virgifera, this binary toxin was cloned into corn plants. Volume 5. The Vip2A attaches a ADP-ribose moiety to a monomeric G-actin, affecting its polymerization and the integrity of the cytoskeleton [39]. It was proposed that it could block the active site or the NAD-binding site. A study on the distribution pattern of Aphis gossypii Glover and its coccinellid predator, Menochilus sexmaculatus Fabricius, was conducted in a chilli ecosystem at the experimental field of Universiti Putra Malaysia. The aphids' impact is especially important on vegetable crops such as courgette, melon, cucumber, aubergine and strawberry and on cotton, citrus and mallow. [3] Winged forms then migrate to secondary host species in the families Rosaceae, Chenopodiaceae, Malvaceae, Cruciferae, Cucurbitaceae, Solanaceae, Compositae and others. By continuing you agree to the use of cookies. Distribution. It is distributed almost worldwide, and is particularly abundant in the tropics. Aphis gossypii is a tiny insect or greenfly in the superfamily Aphidoidea in the order Hemiptera.It is a true bug and sucks sap from plants. (See color figure 158. Indeed, aphids were shown to be able to acquire and transmit efficiently PRSV-W from commercial infected melon fruits. In Insects of Hawaii. According to Nelson (2001), pests known to attack noni in Hawaii include aphids (Aphis gossypii), ants, scales (the green scale), mites (eriophyid mites), whiteflies (fringe guava whitefly), and slugs. In the southeastern United States, frequent rainfall in the fall limits the accumulation of honeydew except in dry years. United States: southeastern and southwestern United States. Homoptera: Sternorhyncha. The foliage may become chlorotic and die prematurely. Pesticides such as Abamectin and Acetamiprid are applied on trees to control the pest. Vector of crinkle, mosaic, rosette and other virus diseases. The total number of apterous aphid per plant stratum was significantly different among plant strata of a particular variety (treatment) as well as among the treatments. The population abundance and spatial distribution of the aphids, Aphis gossypii Glover (Homoptera: Aphididae) and its predator coccinellids (adult) on chilli var. It thrives outdoors in southern Europe but survives only under glass in northern Europe. Aphis cucurbiti Buct. The zymogenized form of Vip2 interfered with its enzymatic function.

The oval eggs are yellow when first laid but soon turn glossy black. [5], "Influence of abiotic factors on some biological and ecological characteristics of the aphid parasitoid, https://en.wikipedia.org/w/index.php?title=Aphis_gossypii&oldid=997517464, Creative Commons Attribution-ShareAlike License, This page was last edited on 31 December 2020, at 22:27. However, there is evidence that on a global scale the name A. gossypii is being applied to a number of forms with different life cycles and/or host-plant associations. The study had revealed that distribution of M . [3] These mature in about twenty days at 10 °C and in about four days at 30 °C. The Aphis gossypii is a very polyphagous Afide with an adult measuring approximately 2 mm in length and with a very variable color, from greenish to dark grayish. Attitude and biological cycle – However, as with thrips and whiteflies, greatest damage from these pests may be caused by transmission of plant viruses.

In the tropics Aphis gossypii is a major pest of cotton. OCT/1991 . Greenhouse crops are damaged by numerous aphid pests, but a few highly polyphagous species, including green peach aphid Myzus persicae, melon aphid Aphis gossypii, potato aphid Macrosiphum euphorbiae, and foxglove aphid Aulacorthum solani, are of primary importance (Chow and Heinz, 2004). In the former Soviet Union it is found up to 54°N. In Canada, it is widespread in the eastern portion of the country, extending at least as far west as Manitoba; frequent injury is limited to southern Ontario and Quebec. Distribution. Aphis gossypii Glover (Hemiptera: Aphididae) is a destructive pest of numerous crops worldwide. It is cosmopolitan in habitat. Its direct damage is much less important than its role in transmitting virus diseases. USSR), Afghanistan, Bonin Islands, Burma, Ceylon, China, Cyprus, Gaza, Strip, Hong Kong, … It is a true bug and sucks sap from plants. ), J. Leland, J. Gore, in Microbial Control of Insect and Mite Pests, 2017. [1] One which shows promise as a biocontrol agent is Aphelinus asychis. A. gossypii is extremely polyphagous and very damaging to many economically important crops, including cotton, aubergine, citrus, coffee, melon, okra, peppers, potato, squash and sesame. Aphids, particularly Aphis gossypii and others (Hemiptera: Aphididae) are soft-bodied insects, 1–2 mm long, yellowish green to black, with or without wings. Here, both males and sexual females are produced, mating takes place and the females lay eggs which overwinter, ready to repeat the life cycle the following year. Aphis gossypii Glover is a polyphagous aphid pest with a worldwide dis-tribution. Crystal structure of Vip2A toxin. This sap-sucking insect affects plants via direct feeding and indirectly via plant viral disease transmission (more than 50 plant pathogenic viruses known). [1], It is not known where this species originated, but it is now found in tropical and temperate regions throughout the world except extreme northern areas. It is common in North and South America, Central Asia, Africa, Australia, Brazil, East Indies, Mexico and Hawaii and in most of Europe. Information is given on the geographical distribution in EUROPE (excl. A. Carrillo-López, E.M. Yahia, in Postharvest Biology and Technology of Tropical and Subtropical Fruits: Mangosteen to White Sapote, 2011. We use cookies to help provide and enhance our service and tailor content and ads. Other vegetable crops attacked include pepper, eggplant, okra and asparagus. It is a major pest of cotton and cucurbits. The body appears dull because it is dusted with wax secretions.
