Abstract
Variations in cropping practices significantly affected the abundance of the Mexican bean beetle, Epilachna varivestis Mulsant, and the redlegged grasshopper, Melanoplus femurrubrum (De Geer), in southern Indiana soybeans. Mexican bean beetle adults and larvae were more abundant in tilled soybeans than in no-till soybeans. The Mexican bean beetle was limited to one larval generation on double crop soybeans, while 2 generations developed on early planted soybeans. Late in the season, Mexican bean beetle adults left the nearly mature early planted soybeans and aggregated on the late developing double crop soybeans. No-till planting in conjunction with soybean double cropping favored redlegged grasshopper populations by providing a continuous suitable habitat for their development. Changes in row-width (from 97 to 48 cm) did not significantly affect the abundance of either of these pests in double crop soybeans.This publication has 1 reference indexed in Scilit:
