Abstract
The incidence levels of moths and larvae of Etiella zinckenella were studie d in the reproductive stage of soybean at eight farmers' field sites. A pos itive relationship was found between moths, caught by sweeping during flowe ring and pod-formation, and seed damage. Hence, rough predictions of damage can be made based on moth catches. Damage incidence was recorded in unspra yed plots and in plots sprayed with deltamethrin during flowering and pod-f ormation. Spraying did not affect the densities of moths and larvae or dama ge to pods and seeds. Larvae of H. armigera, Spodoptera litura and Plusiina e were not affected by spraying, but the pod-sucking bug Riptorus linearis, and two groups of predators, spiders and coccinellids, were reduced.
