Abstract

The synthetic plant growth regulator indolebutyric acid delayed pupation, produced lighter pupae, and interfered with the larva-to-pupa molt of the western tent caterpillar, Malacosoma californicum pluviale (Dyar), when it was mixed with water (0.1 g/1.) in which cut foliage for rearing the larvae was kept. Treatment of very young larvae led to adults that produced more and better eggs than the controls. Treating older larvae produced antigonadotrophic effects.
