Life history parameters (±SEM) of A. gossypii at … Major aphids found in Nepal are Green peach aphid (Myzus persicae), Cabbage aphid (Brevicoryne brassicae), mustard aphid (Lipaphis erysimi), Cowpea aphid (Aphis craccivora), Bean aphid (Aphis fabae), Cotton aphid (Aphis gossypii), Banana aphid (Pentalona nigronervosa) etc which have high occurrence. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Common Name: Cotton aphid or melon aphid Scientific Name: Aphis gossypii Glover Order: Homoptera Description:Adult aphids are winged or wingless, soft bodied yellow to dark green aphids 1/16 inch or less in size.Winged forms have a black head and thorax and hold their wings roof-like … Common names. Aphis gossypii is an important cosmopolitan pest on Malvaceae and Cucurbitaceae plants (Carletto et al., 2009; Ebert and Cartwright, 1997).Cotton aphids present a similar life-cycle as other aphids species ().During spring and summer, the parthenogenetic population expands rapidly, resulting in a high nutrient consumption of the host plant. Instar-specific and total nymphal development duration (±SEM) of .4. gossypii at six constant temperatures in the laboratory, 2003 27 2.3. Aphids have many generations a year. Adults pass the winter on greens and other wild hosts. Aphis gossypii is one of the most biologically diverse and widely distributed aphid species. Life cycle: LIFE CYCLE. Problems in the designation of type of life cycle and the evolutionary significance of the life cycle … Winged forms migrate to other hosts in late spring. During these migratory flights, aphids may spread viral diseases from infected volunteer plants and weeds to healthy crops. Life Cycle and Description The life cycle differs greatly between north and south. Aphids have piercing-sucking mouthparts and have two protrusions on their rear tips called cornicles. Aphis spiraecola and Aphis gossypii are the most abundant and diverse species in the region. Young aphids are called nymphs. Although size can vary based on environmental conditions, adult aphids tend to be about 1/16th inch in length, are soft bodied and pear shaped. Most aphids in California's mild climate reproduce asexually throughout most or all of the year with adult females giving birth to live offspring—often as many as 12 per day—without mating.
