AbstractEffects of soil moisture, texture, and temperature on larval and pupal survival and development of the bean leaf beetle, Cerotoma trifurcata (Forster), were investigated in laboratory and greenhouse studies. In both cases, mortality rates were highest during the first instar, decreased during subsequent larval instars, then increased during the pupal stage. Under constant laboratory conditions, survival and adult weights were highest in wet and organic soils and lowest in dry and loamy sand soils. In wet and organic soils, developmental time was shorter than in other soils.Although survival/plant in the greenhouse was greatest in sandy clay loam, survival/nodule was greatest in organic soil.These studies, together with oviposition preference, egg survival, and larval movement experiments agree with field observations and provide some explanations for observed patterns of local and regional abundance of the bean leaf beetle in North Carolina.

A field population of bean leaf beetle, Cerotoma trifurcata (Forster), adults on soybean, cv. Lee, in north Mississippi showed consistent frequencies of occurrence of polymorphic forms during the growing season. The greatest percentage of beetles were in the beige with spots category (62%), followed in order by beige without spots (27%), crimson with spots (8%), and crimson without spots (3%). Field-collected adults experimentally transmitted bean pod mottle virus from infected soybean plants, cv. Bragg, to healthy seedlings (1st trifoliolate) after a 24-h acquisition feeding on virus infected source plants with equal degrees of polymorph transmission efficiency (29 - 35%, n.s.).
