Southern Bean Mosaic Virus in Mexican Bean Beetle and Bean Leaf Beetle Regurgitants

The Mexican bean beetle (Epilachna varivestis) regurgitome and insights into beetle-borne virus specificity

For nearly 400 million years, insects and plants have been embattled in an evolutionary arms race. Insects have developed diverse feeding strategies and behaviors in an effort to circumvent and overcome an extensive collection of plant defense tactics. Sap-sucking insects often inject saliva into hosts plants, which contains a suite of effector proteins and even microbial communities that can a...

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...

An effect of sub-lethal doses of cryolite on Mexican bean beetle larvae, Epilachna varivestis.

RNAi-mediated resistance to Bean golden mosaic virus in genetically engineered common bean (Phaseolus vulgaris).

Bean golden mosaic virus (BGMV) is transmitted by the whitefly Bemisia tabaci in a persistent, circulative manner, causing the golden mosaic of common bean (Phaseolus vulgaris L.). The characteristic symptoms are yellow-green mosaic of leaves, stunted growth, or distorted pods. The disease is the largest constraint to bean production in Latin America and causes severe yield losses (40 to 100%)....

Evaluation 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 ...
