Abstract

The biology and control of Hypsipyla robusta (Moore).

Abstract

In field studies conducted in Yunnan, China, Hypsipyla robusta had 4 generations each year and overwintered as a pupa. Larvae bored into the branches of Chinese toon (Toona sinensis). Sixty to 100% of trees were injured at the thicket stage. The distribution, injuriousness, occurrence, biology and control of H. robusta are described. Control is based on silvicultural management, pest forecasting and surveys, and includes manual control during the winter and spring, and chemical control during the summer and autumn augmented with biological control.
