Abstract

Suppression of Lymantria obfuscata Walker by sex pheromone trapping of males.

Abstract

The effect of disparlure on the suppression of mating by disrupting pheromonal communications between the sexes of L. obfuscata was studied in apple orchards with willow [Salix] and poplar [Populus] in Kashmir, India. Removal of a substantial proportion of males by pheromone traps resulted in a significant suppression of mating as shown by the egg mass count before bud burst and after leaf fall. Reduction of egg mass density was between 62.02 and 77.97%.
