Aphids prefer to feed on young leaves, shoots, flowers and immature seed pods. Bangkok, Thailand: Regional Office for Asia and the Pacific region (RAPA). In 1987, the average temperature was lower (11.1-13.3°C) during this period, while rainfall was relatively high (125 mm), and aphid reproduction did not begin until the beginning of June (Kuroli et al., 1988). First record of Aphis craccivora Koch 1854 (Hemiptera: Aphididae) on weed in Santa Maria, RS State. Study on methods for controlling aphis in commercial lucerne production. Micromus timidus, and a predatory dipteran, e.g. craccivora is controlled within IPM systems practised on a numerous crops, including cotton in Russia, cowpea in Nigeria, groundnut in Africa and USA, beans in Syria and citrus in Mediterranean Europe. Predation effectiveness of syrphids (Diptera: Syrphidae) on Aphis craccivora Koch (Homoptera: Aphididae) in Eastern Africa. Indian Journal of Entomology. A. craccivora is polyphagous, and reservoirs of aphids and associated disease infection can exist on non-crop plants throughout the year.Groundnut rosette virus Groundnut plants take on a bushy appearance due to attack by A. craccivora and infection with rosette virus. The economic damage due to aphids varies with the stage of plant development, with most damage caused if aphids infest the growing points of groundnut early in the plant's development (Mayeux, 1984). A new virus involved with leaf crinkle disease of urdbean (Vigna mungo) was observed in Himachal Pradesh, India. craccivora was reported transmitting five isolates of Peanut stripe virus (PStV) on groundnut in China (Chen et al., 1999).

Arabidopsis thaliana is a host of the legume nanovirus Faba bean necrotic yellows virus. Photoperiodic regulation of the development of winged gynoparae in the aphid, Aphis fabae. Biotechnol., 7(14), 2486-2490. Corpus allatum activity associated with development of wingbuds in cabbage aphid embryos and larvae. For example, the incidence of beet yellows was reduced where the distances between plants or between rows were reduced (Blencowe and Tinsley, 1951). Insect Environment, 5(2):75. A strong negative relationship was found between the concentration of the tannin, procyanidin, in the leaf bud petioles of seven genotypes of groundnut and fecundity of A. craccivora (Grayer et al., 1992). These variably wrinkled leaflets have edges more serrated thanusual. Severe tornadoes can stop swarms of aphids, while heavy rains can destroy colonies on young plants, where foliage is not plentiful enough to protect them (Mayeux, 1984). Hamid et al.

Indirect damage caused by A. craccivora is due to the production of honeydew and the transmission of plant viruses. Path. Resumo. Infection with Peanut mottle virus led to a mean yield loss of 20%/plant in Georgia, USA, in 1973 (Kuhn and Demski, 1975).

A typical groundnut yield in Africa would be around 450-670 kg/ha, but using insecticides and other management practices yields over 1300 kg/ha can exceptionally be achieved.

Incoming viruliferous alatae initiate the infection and yield loss is greatest when aphids arrive early in the crop's development. divaricata, US Fish and Wildlife Service, It is a major economic pest of groundnut and cowpea, particularly in the tropics, and a significant pest of mungbean (Vigna radiata), pigeonpea (Cajanus cajan), chickpea (Cicer arietinum), field and green beans (Vicia spp. An interesting interaction has been observed between ZYMV and A. gossypii, an aphid vector colonizing cucurbit crops.
