The spring occurrence of populations of the cotton aphid, Aphis gossypii GLOVER, the seasonal variation in their aliesterase activity, and their susceptibility to organophosphorus insecticides were investigated using eggplants (Solamm melongena L.) and cucumbers (Cucumis sativus L.) cultured without insecticides in a plastic greenhouse (all sides open) and in a field at Higashihiroshima in Hiroshima Prefecture from 1987 to 1990. In the spring. populations of aphids on eggplants increased rapidly and dispersed. but those on cucumbers hardly increased. There were two peaks of 0-5 and 15-25 nmol/10 min/μg protein in the frequency distribution of aliesterase activity in apterous adults on eggplants and cucumbers. Consequently, individuals could be divided into a low-activity group, and a high-activity group. The majority of individuals on eggplants in the plastic greenhouse had low aliesterase activity but those on cucumbers had high activity. However, some individuals with high aliesterase activity were observed in the populations on eggplants, and the frequency tended to be higher in the autumn and in the field than in the plastic greenhouse. Individuals with low aliesterase activity were also found in the populations on cucumbers, but they did not become predominant. Susceptibility to fenitrothion was higher in the populations on eggplants than those on cucumbers which paralleled the aliesterase activity. The control effect of fenitrothion was also higher for populations on eggplants than on cucumbers.
