Species diversity and number of potential pollinator species on H. officinalis seed crops in various ecotopes of farm fields were studied under the influence of “Bi-58 new” insecticide treatment and without preliminary treatment. The presence of 16 insect species belonging to four families of the genus Hymenoptera (Megachilida, Apidae, Halictidae and Vespidae), two families of the Diptera row (Syrphidae and Stratiomyidae) and one family of the genus Lepidoptera (Lycaenalidae) has been identified on the seed crops of H. officinalis. The insecticidal treatment in general did not significantly affect the total number of pollinators, but changed the species composition of pollinators and their number on the field area. As much as possible, the decrease in the prevalence and number of the Megachilida species was affected.

The dynamics of behavioral reactions is studied. Habit, live weight of roosters in artificially created models of desynchronosis: acute, due to three-day inversion of the light regime, and chronic, due to crowding increased placing density. An assessment of the behavior, habitus, feed intake, feather cover and molting conditions in combination with the glycemia level, which together provide an objective assessment of the effect of desynchronosis on the functional state of birds and their adaptation to acute and chronic stress.
