Five years ago, bees made headlines when a mysterious condition called colony collapse disorder decimated honey bee colonies in parts of the United States. Now bees are poised to be in the news again, this time because of evidence that systemic insecticides, a common way to protect crops, indirectly harm these important pollinators. Two field studies reported online this week in Science document problems. In bumble bees, exposure to one such chemical leads to a dramatic loss of queens and could… Expand
Risk Assessment of Pesticidal Toxicity and Threats on Pollinators: A Review on Honey Bee
Sustainable agriculture, effective policy and proper management can decrease pollinators' risk by helping to diversify the agriculture for pollen and nectars with reduced usage of pesticides and propermanagement. Expand
Neonicotinoid pesticides and nutritional stress synergistically reduce survival in honey bees
The results provide the first demonstration that field-realistic nutritional stress and pesticide exposure can synergistically interact and cause significant harm to animal survival. Expand
An Inventory of Documented Diseases of African Honeybees
This review provides a comprehensive update on the documented diversity and geographic distribution of honey bee pathogens and points to the need of further information on these constraints of honeybee health. Expand
Neonicotinoids, bee disorders and the sustainability of pollinator services
The limited available data suggest that neonicotinoids are likely to exhibit similar toxicity to virtually all other wild insect pollinators, therefore a transition to pollinator-friendly alternatives to neonicotine is urgently needed for the sake of the sustainability of pollinator ecosystem services.

Effect of thiamethoxam on foraging activity and mortality of Apis mellifera (L.)
Thiamethoxam had a negative impact on foraging activity and cause mortality of honey bees for a period of three to four days following the spraying in field condition. Expand
Repellent effects of insecticides on Stephanitis pyrioides Scott (Hemiptera: Tingidae) under laboratory conditions
Pest management can be improved by using insecticides that repel S. pyrioides, which is an important insect pest of azalea plants in the USA. Expand
Comparison of the contents of selected elements and pesticides in honey bees with regard to their habitat
The research indicates the markers of contamination: Al, As, and Cr on the surface and Cd inside the bodies of honey bees, and the large city environment is not harmful for honey bees. Expand
Layout 1
Almost overnight, genetically engineered (GE) crops have profoundly changed agriculture in the U.S. Leading the way have been corn, soybean, and cotton crops resistant to the herbicide glyphosate. AsExpand
A common neonicotinoid pesticide, thiamethoxam, impairs honey bee flight ability
These results provide the first demonstration that acute or chronic exposure to a neonicotinoid alone can significantly alter bee flight and may impair foraging and homing, which are vital to normal colony function and ecosystem services. Expand
Non-target toxicity of novel insecticides
This review summarises recent literature published on non-target toxicity of neonicotinoids, pyrethroids, and neem-based insecticidal substances, with a special emphasis on neonicsotinoid toxicity in honeybees. Expand
