| Abstract | ||||
| The biological effectiveness of some insect growth regulators (the anti-moulting agent (teflubenzuron) and the neem seed kernel extract (azadlrachtin)) were evaluated against all stages of the tortoise beetle Cassida vitiate Vill. infesting sugar beet plants at Kati' El-Sheikh Governorate during two successive seasons (1999/2000 and 2000/ 2001). This evaluation was conducted in comparison with one of the recommended organophosphorus insecticide namely, profenofos. The obtained results showed that, profenofos was the most effective compound against C. vittata under field conditions, but was very harmful against its associated natural enemies. Teflubenzuron and azadirachtin exhibited sufficient effectiveness as biorational compounds in controlling C. vitiate and showed much lower toxicity against its associated predators. These biorational compounds could therefore be involved in integrated pest management program against this pest on sugar beet. | ||||
