Bean leaf beetles, Cerotoma trifurcata (Forster), were reared from egg to adult at temperatures from 18 to 32°C. To maximize larval survivorship, larvae were fed cotyledons of cowpea, Vigna unguiculata (L.). To test the effect of larval diet, other

Effects of a mixture of the postemergence herbicides acifluorfen and bentazon, and simulated defoliation expected from green cloverworm on population densities of Heterodera glycines were determined in field plots in Iowa. The herbicide mixture and d

Amethod was developed to use the sequential probability ratio test of Wald (sequential sampling) in a time-oriented sense rather than in a spatial sense. The method allows a grower or scout to decide if a population is of an endemic or outbreak type

Plots measuring 25 ft by 4 rows (30-inch centers) were replicated 4 times in a randomized complete block design. Before planting, meat and bonemeal (1 liter/25 row-ft) was applied over the rows to enhance seedcorn maggot (SCM) oviposition. Plots were
