Condition of entomophilic fauna on Hyssopus officinalis L. crops depending on ecotope conditions

Abstract

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.
