The leafcutter bee, Megachile rotundata, is more sensitive to N-cyanoamidine neonicotinoid and butenolide insecticides than other managed bees

Is Apis mellifera more sensitive to insecticides than other insects?

BACKGROUND Honey bees (Apis mellifera L.) are among the most important pollinators in natural and agricultural settings. They commonly encounter insecticides, and the effects of insecticides on honey bees have been frequently noted. It has been suggested that honey bees may be (as a species) uniquely sensitive to insecticides, although no comparative toxicology study has been undertaken to exam...

Neonicotinoid insecticides and bees

The alfalfa leafcutting bee, Megachile rotundata: the world's most intensively managed solitary bee.

The alfalfa leafcutting bee (ALCB), Megachile rotundata F. (Megachildae), was accidentally introduced into the United States by the 1940s. Nest management of this Eurasian nonsocial pollinator transformed the alfalfa seed industry in North America, tripling seed production. The most common ALCB management practice is the loose cell system, in which cocooned bees are removed from nesting cavitie...

p63 is more sensitive and specific than 34βE12 to differentiate adenocarcinoma of prostate from cancer mimickers

Objective(s): Prostate cancer is the world’s leading cause of cancer and the second cause of cancer-related death in men after lung cancer. Differentiation of prostate adenocarcinoma from benign prostate lesions and hyperplasia sometimes cannot be done on the basis of morphologic findings. Considering the fact that in the prostate adenocarcinoma there is no basal cell layer, basal cell markers ...

Neonicotinoid Insecticides and Honey Bees: Technical Answers to FAQs

Neonicotinoids are a class of insecticides with the same mode of action as nicotine. Examples include imidacloprid, thiamethoxam, clothianidin, acetamiprid, thiacloprid and dinotefuran. These compounds interfere with the transmission of impulses in the nerve system of insects. Similar to the naturally occurring signal-transmitting acetylcholine, neonicotinoids stimulate certain nerve cells by a...
