Abstract

Evaluation of certain insecticides and intervals between applications for control of the leopard moth, Zeuzera pyrina L., on pear trees.

Abstract

Field tests were carried out at Fayoum, Egypt, in 1974-75 on the chemical control of larvae of Zeuzera pyrina (L.) on pear trees. The results showed that 5 or 6 sprays of phenthoate (Cidial) at 0.2%, and mixtures of endrin and dicrotophos (Bidrin) at 0.35% and DDT and parathion-methyl (methyl parathion) at 0.5 and 0.15%, respectively, applied at 3-week intervals (starting in mid-May and ending about mid-September, with a 3-week gap before harvest) gave the best control of the moth.
