Abstract
The efficiency of profenofos, carbosulfan and chlorfenapyr, was evaluated against eggs, larvae, pupae and adults of the tortoise beetle Cassida vittata Vill. inhabiting sugar beet fields in Kafr El-Sheikh Govemo­rate during 1999/2000 and 2000/2001 sugar beet growing seasons. Data obtained revealed that when mortality rates were considered, pro­fenofos and carbosulfan were the most efficient compounds on eggs, lar­vae, pupae and adults of C. vitiate. However, chlorfenapyr, demon­strates a moderate toxic effect. The side effects of the tested insecticides on the associated bio­agents, viz. Coccinella undecimpunctata Reiche, Chrysoperla camea Steph. and Paederus allied; Koch was studied. Unfortunately, profenofos and carbosulfan demonstrate unacceptable toxic effect. Chlorfenapyr was moderately effective either in controlling the insect pest or in its side effect on the associated predators.
