Abstract |
Field experiments were conducted during 2001 and 2002 cotton seasons at Kafr El-Sheikh, Egypt. The effects of early-season insecticide treatments on the interrelations between the early and late-season populations of certain sucking pests and their associated predators were studied.
The data revealed that the correlations between the early-season populations of the sucking pests and their associated predators were positive, while no such correlations existed between the late-season populations of the pests and predators. The interrelations were negative between the early-season populations of the predators and the late-season populations of the sucking pests.
The data also showed that the early-season insecticide treatments reduced the early-season populations of the sucking pests and predators. The effects of the early-season insecticide treatments were extended to the late-season populations of the predators. The increase in the late-season populations of the pests may be due to the decrease in the early-season populations of the predators in the treated fields.
