Confirmation of bean leaf beetle, Cerotoma trifurcata, feeding on cucurbits
The objective of these studies was to assess the degree to which bean leaf beetle, Cerotoma trifurcata (Forster), will feed on cucurbits. In 2003, we documented an infestation of C. trifurcata in a commercial pumpkin field near Rosemount, MN, USA. To evaluate C. trifurcata feeding on cucurbits, we conducted laboratory no-choice and choice test feeding studies. In the laboratory, C. trifurcata f...
متن کاملEvaluation of Organic Pest Management Treatments for Bean Leaf Beetle and Soybean Aphid Neely-Kinyon Trial, 2004
The soybean aphid (Aphis glycines Matsumura) is native to China and Japan, and was a new pest in Iowa in 2000. Aphid numbers were high in the 2001, but in 2002 and 2003, aphids appeared to be less of a problem. This small, yellow aphid has distinct black cornicles (“tailpipes”) on the tip of the abdomen and develops colonies on soybean plants as winged and wingless forms. Aphids feed through pi...
متن کاملPopulation Dynamics of Bean Leaf Beetle, <i>Cerotoma trifurcata</i> (Coleoptera: Chrysomelidae) on Edamame Soybean Plants In Nebraska

Bean leaf beetle, Cerotoma trifurcata, is a sporadic pest of soybean in Nebraska, however, its pest status and abundance has increased in the recent years due to an increase in soybean acreage. This was a field experiment aimed at determining the populatio...
متن کاملCircadian leaf movements in biloxi soybeans.
Leaf movement in Biloxi soybean has been investigated in some detail by Bunning (1) and Holdsworth (2). The results and the interpretations presented by these investigators differ with regard to the nature of the leaf movement response. Bunning considers the leaf movement to be a circadian manifestation of the physiological clock, while Holdsworth considers it to be essentially a photonastic re...
متن کاملEvaluation of Organic Pest Management Treatments for Bean Leaf Beetle⎯Neely-Kinyon Trial, 2001-2005
Introduction Annual organic soybean [Glycine max (L.) Merr.] production in the U.S. has risen to more than 150,000 acres (USDA-AMS, 2010). Critical challenges associated with organic soybean production include weed control and bean leaf beetles (Cerotoma trifurcata Förster) – primarily as vectors for the seed-staining bean pod mottle virus (BPMV) and for providing sites for other seed-staining ...
