The honey bee Apis mellifera plays a significant role as a pollinator of native and cultivated
plants, by increasing the productivity of several cultures, preserving the flora, and producing …

This investigation was undertaken to determine whether active ingredients (AIs) of currently
recommended plant protection products (PPPs) could be transferred to beehives from apple …

Field tests verified and evaluated a pesticide's active ingredient transfer to honeybee hives
from rapeseed crops protected according to current programs. Samples of rapeseed flowers …

We examined the susceptibility of the worker honeybee Apis mellifera L. to pyrethroids. Bees
were intoxicated by selected synthetic pyrethroids (active substances: beta-cyfluthrin …

A circadian clock may underlie pesticide resistance mechanisms in organisms that are very
important for humans, for example, in the honey bee (Apis mellifera). Using the gas …

Field studies were conducted to evaluate the transfer of active ingredients (AIs) of plant
protection products (PPPs) to beehives. They were applied in two commodity red raspberry …

BACKGROUND The ectoparasitic honey bee mite Varroa destructor is a main cause of the
gradual decline in honey bees Apis mellifera. Beekeepers currently utilize a wide range of …

Simple Summary The oscillator, the core element of the biological clock, is a mechanism
operating at the molecular level that is responsible for the generation of rhythms. It is …

Many factors may affect pesticide effectiveness against pests. One of the factors that should
be considered is circadian rhythmicity. In this study, we evaluated daily variations in …

Understanding how endogenous and exogenous factors such as annual seasonal rhythm
and photoperiodism affect pesticide toxicity is important to designing integrated pest …
