Evaluation of acute contact toxicity of imidacloprid and thiacloprid to honey bees: A comparative analysis of effects on survival and behavioral activity
The paper presents the results of a study of the acute contact toxicity of imidacloprid and thiacloprid to honey bees (Apis mellifera Linnaeus, 1758). The experiment assessed survival and behavioral activity of insects at 4, 24, and 48 hours after a single exposure to various concentrations of the insecticides. It was found that both compounds exhibit high insecticidal activity; ...
Genetic lability of Varroa Destructor as a factor of the epizootic process in Apis Mellifera Carpatica populations
The global decline of honey bee (Apis mellifera) populations poses a serious threat to crop pollination and global food security. Among the multiple factors causing colony weakening and loss, varroosis, an invasive disease caused by the ectoparasitic mite Varroa destructor, plays a pivotal ...
Genetic variability and phylogeographic relations of Nosema Apis at the apiary level
The results of a comprehensive analysis of the genetic diversity of the microsporidian Nosema apis, the causative agent of nosemosis in honey bees (Apis mellifera), are presented using the example of a single apiary located in the Laishevsky District of the Republic of Tatarstan. Identification of the haplotypic composition of the pathogen and assessment of its phylogeographic relationships with Eurasian ...
Neonicotinoids and their effects on honey bees: a comparative analysis of the acute oral toxicity of imidacloprid and thiacloprid
A comparative study of the acute oral toxicity of the neonicotinoid insecticides imidacloprid and thiacloprid with respect to honey bees (Apis mellifera) was conducted. Under laboratory conditions, survival dynamics, changes in locomotor activity, and the repellent effect were examined under exposure to various concentrations of these compounds. The study established that both insecticides exhibit ...
