Assessing the Influence of Bt Crops on Natural Enemies
Transgenic Bt crops expressing proteins derived from Bacillus thuringiensis (Bt) currently are grown commercially in ten countries on over 20 million hectares. Assessing their environmental safety is a critical part of the regulatory approval process and product stewardship for Bt crops. The environmental safety testing process for Bt crops follows a standard risk assessment approach, and invol...
متن کاملNatural Enemies Delay Insect Resistance to Bt Crops
We investigated whether development of resistance to a Bt crop in the presence of a natural enemy would be slower than without the natural enemy and whether biological control, in conjunction with a Bt crop, could effectively suppress the pest population. Additionally, we investigated whether insecticide-sprayed refuges of non-Bt crops would delay or accelerate resistance to the Bt crop. We use...
متن کاملBt crops benefit natural enemies to control non-target pests
Crops producing insecticidal crystal (Cry) proteins from Bacillus thuringiensis (Bt) control important lepidopteran pests. However, pests such as aphids not susceptible to Cry proteins may require other integrated pest management (IPM) tactics, including biological control. We fed aphids on Bt and non-Bt plants and analyzed the Bt protein residue in aphids and compared the effects of Bt plants ...
متن کاملNatural enemies of the gall-maker Eugeniamyia dispar (Diptera, Cecidomyiidae): predatory ants and parasitoids.
Natural enemies of the gall maker Eugeniamyia dispar (Diptera: Cecidomyiidae) were studied on the urban area of Porto Alegre, RS, Brazil from October 1993 to March 1996. Galls and associated arthropods were followed weekly in the field on individual host plants (Eugenia uniflora, Myrtaceae) and also in the laboratory. Three species of ants attacked the galls, the most common being Pseudomyrmex ...
