Biological Parameters of Convergent Lady Beetle (Coleoptera: Coccinellidae) Feeding on Aphids (Homoptera: Aphididae) on Transgenic Potato
TLDR
Exposure to δ-endotoxin of Bacillus thuringiensis tenebrionis has no statistically significant effect on survival, aphid consumption, development, or reproduction in beetles.Abstract:
We exposed larval and adult Hippodamia convergens (Guerin-Meneville), convergent lady beetle, to Myzus persicae (Sulzer), green peach aphid, reared on potatoes expressing δ-endotoxin of Bacillus thuringiensis tenebrionis . Because the toxin may be ingested by the aphid, the beetle may in turn be exposed to the toxin. However, we measured no statistically significant effect on survival, aphid consumption, development, or reproduction in beetles.read more

Transgenic crops expressing Bacillus thuringiensis toxins and biological control.
TL;DR: Because Bt-transgenic varieties can lead to substantial reductions in insecticide use in some crops, they can contribute to integrated pest management systems with a strong biological control component.
Journal ArticleDOI
The Ecological Risks and Benefits of Genetically Engineered Plants
TL;DR: A review of existing scientific literature reveals that key experiments on both the environmental risks and benefits are lacking, and existing studies emphasize that these can vary spatially, temporally, and according to the trait and cultivar modified.

Safety and Advantages of Bacillus thuringiensis-Protected Plants to Control Insect Pests
TL;DR: Plants modified to express insecticidal proteins from Bacillus thuringiensis (referred to as Bt-protected plants) provide a safe and highly effective method of insect control and reduce reliance on conventional chemical pesticides.
Journal ArticleDOI
Understanding and Manipulating Plant Attributes to Enhance Biological Control
TL;DR: It is suggested ways of manipulating morphological and chemical attributes of crop plants for a more sustainable and balanced control of insect pests in agro-ecosystems.

Assessing environmental risks of transgenic plants
David A. Andow,Claudia Zwahlen +1 more
TL;DR: This review focuses on changes in the assessment of risks associated with non-target species and biodiversity, gene flow, and the evolution of resistance in the environmental risk assessment process since 1990.

The effects of microbial pesticides on non-target, beneficial arthropods
TL;DR: Beneficial insects can be caused by bacterial and protozoan microbial pesticides and unique standard methods need to be developed for microbial assays for expressing more exactly the dosage administered to the host or natural enemy.
Journal ArticleDOI
History, Use, and Future of Microbial Insecticides
TL;DR: The use of microbial insecticides is growing at a rapid pace of 10–25% peryear compared with chemical insecticides at 1–2% per year, and Bacillus thuringiensis Berliner is primarily responsible for this growth.

Temperature-Dependent Development of the Convergent Lady Beetle (Coleoptera: Coccinellidae)
TL;DR: In this paper, the authors compared the development of Hippodamia convergens Guerin-Meneville at six constant temperatures and found that the heat-unit requirements for development from egg to adult were 228 degree-days above a developmental threshold of 12.5°C.
