Binodoxys communis | |
Binodoxys communis is a parasitoid wasp of the genus Binodoxys . The genus Binodoxys is located in the subfamily Aphidiinae which are noted parasitoids of aphids.
The adults of Binodoxys communis are approximately 1.2 mm in length. This small braconid wasp has a brown head, antennae, legs, and thorax. The wing venation is brown and the wings are nearly hyaline. The first tergite, trochanters, and the base of the tibiae are yellow. The rest of the abdomen is brown. Ovipositer sheaths and prongs are relatively lighter in color. [2]
Binodoxys communis was released in the United States prior to 1979 to control Aphis gossypii (Glover), but establishment resulting from that release was questionable. [3] Binodoxys communis was vetted and released in the United States again in 2007 to control the soybean aphid, Aphis glycines Matsumura. [4] Establishment of B. communis throughout the United States has been questionable, likely due to reduced aphid population because of fungal pathogens, competition with other species of parasitoid, and prophylactic usage of pesticides.
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in colour. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving living birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescopic development—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonise new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs.
The Aphididae are a very large insect family in the aphid superfamily (Aphidoidea), of the order Hemiptera. Several thousand species are placed in this family, many of which are well known for being serious plant pests. They are also the family of insects containing most plant virus vectors with the green peach aphid being one of the most prevalent and indiscriminate carriers.
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species.
Citrus tristeza virus (CTV) is a viral species of the genus Closterovirus that causes the most economically damaging disease to its namesake plant genus, Citrus. The disease has led to the death of millions of Citrus trees all over the world and has rendered millions of others useless for production. Farmers in Brazil and other South American countries gave it the name "tristeza", meaning sadness in Portuguese and Spanish, referring to the devastation produced by the disease in the 1930s. The virus is transmitted most efficiently by the brown citrus aphid.
Soybean mosaic virus (SMV) is a member of the plant virus genus Potyvirus. It infects mainly plants belonging to the family Fabaceae but has also been found infecting other economically important crops. SMV is the cause of soybean mosaic disease that occurs in all the soybean productions areas of the world. Soybean is one of the most important sources of edible oil and proteins and pathogenic infections are responsible for annual yield losses of about $4 billion dollars in the United States. Among these pathogens, SMV is the most important and prevalent viral pathogen in soybean production worldwide. It causes yield reductions of about 8% to 35% but losses as high as 94% have been reported.
Brevicoryne brassicae, commonly known as the cabbage aphid or cabbage aphis, is a destructive aphid native to Europe that is now found in many other areas of the world. The aphids feed on many varieties of produce, including cabbage, broccoli (especially), Brussels sprouts, cauliflower and many other members of the genus Brassica, but do not feed on plants outside of the family Brassicaceae. The insects entirely avoid plants other than those of Brassicaceae; even though thousands may be eating broccoli near strawberries, the strawberries will be left untouched.
The little black ant is a species of ant native to North America. It is a shiny black color, the workers about 1 to 2 mm long and the queens 4 to 5 mm long. It is a monomorphic species, with only one caste of worker, and polygyne, meaning a nest may have more than one queen. A colony is usually moderately sized with only a few thousand workers.
The Aphidiinae are a subfamily of tiny parasitoid wasps that use aphids as their hosts. Several species have been used in biological control programs of various aphids.
The soybean aphid is an insect pest of soybean that is exotic to North America. The soybean aphid is native to Asia. It has been described as a common pest of soybeans in China and as an occasional pest of soybeans in Indonesia, Japan, Korea, Malaysia, the Philippines, and Thailand. The soybean aphid was first documented in North America in Wisconsin in July 2000. Ragsdale et al. (2004) noted that the soybean aphid probably arrived in North America earlier than 2000, but remained undetected for a period of time. Venette and Ragsdale (2004) suggested that Japan probably served as the point of origin for the soybean aphid's North American invasion. By 2003, the soybean aphid had been documented in Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New York, North Dakota, Ohio, Pennsylvania, South Dakota, Virginia, West Virginia, and Wisconsin. Together, these states accounted for 89% of the 63,600,000 acres (257,000 km2) of soybean planted in the United States in 2007.
Aphis is a genus of insects in the family Aphididae containing at least 600 species of aphids. It includes many notorious agricultural pests, such as the soybean aphid Aphis glycines. Many species of Aphis, such as A. coreopsidis and A. fabae, are myrmecophiles, forming close associations with ants.
Myzus persicae, known as the green peach aphid, greenfly, or the peach-potato aphid, is a small green aphid. It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues. It is also acts as a vector for the transport of plant viruses such as cucumber mosaic virus (CMV), potato virus Y (PVY) and tobacco etch virus (TEV). Potato virus Y and potato leafroll virus can be passed to members of the nightshade/potato family (Solanaceae), and various mosaic viruses to many other food crops.
Diaeretiella rapae is a species of cosmopolitan parasitoid wasp. It parasitizes many species of aphids, but especially the cabbage aphid, Brevicoryne brassicae. It is the only species in the genus Diaeretiella.
Aphelinus is a genus of parasitoid wasps. Several of the species are important because they parasitize agricultural pests, such as the soybean aphid or the Russian wheat aphid -Diuraphis noxia - (A. albipodus Hayat & Fatima, A. asychis Walker, and A. varipes.
Diaphorina citri, the Asian citrus psyllid, is a sap-sucking, hemipteran bug in the family Liviidae. It is one of two confirmed vectors of citrus greening disease. It has a wide distribution in southern Asia and has spread to other citrus growing regions.
Pauesia is a genus of parasitoid wasps in the subfamily Aphidiinae. The species in the genus use the conifer aphids as their host.
Aphis nerii is an aphid of the family Aphididae. Its common names include oleander aphid, milkweed aphid, sweet pepper aphid, and nerium aphid.
Aphis pomi, commonly known as the apple aphid, or the green apple aphid, is a true bug in the family Aphididae. It is found on young growth of apple trees and on other members of the rose family where it feeds by sucking sap. Reproduction is mainly by parthenogenesis, in which unmated females give birth to live young.
Aphidius nigripes is a species of parasitoid wasp in the subfamily Aphidiinae of the family Braconidae. It is the most common parasitoid of the potato aphid Macrosiphum euphorbiae in eastern North America. Many other species of aphids may also serve as hosts.
Pediobius foveolatus (Crawford), is a tiny exotic parasitoid wasp that is used for biological control of Mexican bean beetle, Epilachna varivestis, an important insect pest of snap beans, lima beans, and sometimes soybeans mainly found at economic levels in the eastern United States. Pediobius foveolatus is in the family Eulophidae, and is the most successful biological control agent for Mexican bean beetle. This wasp only attacks beetle larvae, not eggs or adults. It is commonly used by smaller, organic growers; but is also mass released throughout the state of New Jersey, by their state department of agriculture.
Lysiphlebus testaceipes is a species of small braconid parasitoid wasp in the subfamily Aphidiinae. L. testaceipes can utilize numerous species of aphids as hosts and has often been used as a biological control agent against aphid pests. It is considered an invasive species in several European countries.
