Abstract
The sugar-beet fields are inhabited by numerous insect pests and natural enemies. The plant extracts have shown marked insect control potential. Five of aqueous extracts were tested on sugar-beet insects and predators. It is preferable to use the coriander chamomile or chinaberry extracts, each alone, for controlling, the sugar-beet beetle Cassida vittata ViiI., the sugar beet moth, Serobipalpa ocellatella Boyed., the cotton leaf worm, Spodoptera littoralis Boisd. and beetfly, Pegomia mixta. The European corn borer, Ostrinia nubilalis Hub. was efficiently controlled by Greater Ammi extract. The Greater Ammi extract killed neumerous of the predators, specially, the rove beetle, Paederus alfierii Koch and Coccinellids followed by Christmas berry extract. On the other hand; Coriander and Chinaberry were the lowest potential against predators. Treatment with Selecron promoted the toxic effect against the insect pests but became more hazardous to the predators. Generally, Coriander, Chamomile and Chinaberry extracts were more effective in reducing the insect pest populations and less effective on the associated predators.
