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. Common names. 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. During these migratory flights, aphids may spread viral diseases from infected volunteer plants and weeds to healthy crops. This aphid is globally distributed, located in all but the coldest terrestrial habitats. cotton plants to growth chambers for the cotton aphid life history study, 2003 26 2.2. 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.
