Until 1985 discussions of pesticides and honey bee toxicity in the USA were focused on
pesticides applied to crops and the unintentional exposure of foraging bees to them. The …

So far, genetic engineering of plants in the context of insect pest control has involved
insertion of genes that code for toxins, and may be characterized as the incorporation of …

The genetics of arthropod resistance have been studied since the early 20th century, when
Harlan (1916) demonstrated that resistance to the leaf blister mite, Eriophyes gossypii …

This Botanical Briefing examines the hypothesis that modern agricultural practice affects
natural biotic pollination to the extent that crop yields suffer. Few staple foods depend on …

Background Honey bees (Apis mellifera L.) are the most important pollinators of many
agricultural crops worldwide and are a key test species used in the tiered safety assessment …

In a comparative approach, we evaluated the effects of Cry1Ab protoxin, deltamethrin and
imidacloprid insecticides on mortality, syrup consumption, foraging activity and olfactory …

As more transgenic crop plants become commercialised, there is an increasing need for
information on their impacts on honey bees and bumblebees. Direct effects on bees may …

Genetic engineering provides a means to introduce genes into plants via mechanisms that
are different in some respects from classical breeding. A number of commercialized …

The entomopathogenic bacterium Bacillus thuringiensis (Bt) and its toxins are extensively
used for pest control purposes in agriculture, forestry and public health programmes since …

Abstract Transgenic Cry1Ac+ CpTI cotton (CCRI41) is increasingly planted throughout
China. However, negative effects of this cultivar on the honey bee Apis mellifera L., the most …
