Microspatial distribution of pupal green cloverworms, Plathypena scabra (F.) (Lepidoptera: Noctuidae), in Iowa soybean fields
Environmental Entomology 12 (1), 273-276
Abstract: The microspatial distribution of pupal green cloverworms, Plathypena scabra (F.), was studied intensively in six soybean fields during 1979 and 1980. Pupae occurred within the plant canopy and on the soil surface but not below the surface. About 90% of the pupae were collected in the litter on the soil surface. Pupal densities were biased with respect to directional aspect during 1979, with significantly (P < 0.05) more pupae located in southern exposures than northern exposures, but biases were not observed during 1980. No obvious preferences were observed with respect to eastern or western exposures. Pupal densities also varied inversely with distance from the soybean row. The quantity of litter cover seemed to influence pupal distribution. Implications for pupal sampling are discussed.
