Verbatim
e0“severe decrease in cotton aphid numbers occurred on caged plants that treated with insecticides and this decrease continued up to 15 days after spray, then increases in aphid numbers happened and significantly indicated the highest aphid population density at the last inspection.”
t0“cotton”
e1“Density of aphid populations increased rapidly on caged-untreated plants, where insect predators were excluded and no insecticides were applied and declined only after exceeding the carrying capacity of cotton plants.”

- Observation Aphids on predator-excluding untreated caged plants increased rapidly until carrying capacity was exceeded.
- Observation Diafenthiuron was the most toxic insecticide to insect predators.
- Observation Imidacloprid and thiamethoxam were significantly least toxic to insect predators.
