Adaptation of the Stavropol population of the predatory bug Orius laevigatus (Fieber) (Heteroptera, Anthocoridae) to mass rearing conditions
Abstract
Natural geographic range of the predatory bug Orius laevigatus which is widely used for biological control of various insect pests in greenhouses includes Western, Central, and Southern Europe, Mediterranean, Northern Africa, and South Asia. In the former USSR it was recorded in the southern Ukraine, Crimea, Abkhazia, Armenia, Azerbaijan, and Turkmenistan. In 2020 we found O. laevigatus in a sunflower field in Stavropol Territory of Russia. To estimate the biocontrol potential of the Stavropol population, the process of its adaptation to mass rearing conditions was investigated over 17 sequential generations. The experiments have shown that individuals of the Stavropol population did not differ significantly in several important parameters of reproduction and development (female fecundity, survival of preimaginal stages, etc.) under the mass rearing conditions from individuals of the laboratory population reared at these conditions over many tens of generations. These results suggest that the Stavropol population of O. laevigatus originates from bugs sporadically escaped from local greenhouses and mass rearing facilities rather than represents the result of the natural spread from the Black Sea coast caused by global warming.

Biodiversity of soldier flies (Diptera, Stratiomyidae) of the Crimean Peninsula
Abstract
Annotated list of soldier flies (Diptera, Stratiomyidae) of the Crimean Peninsula is presented. It comprises 42 species from 14 genera of 6 subfamilies. Nine species are recorded for the first time in the Crimea. The fauna of Stratiomyidae of the Crimean Peninsula is compared with the faunas of countries situated around the Black Sea (Romania, Bulgaria and Turkey).

Two new species of the genus Mikluchomaklaia Gorochov (Orthoptera, Gryllidae: Phalangopsinae) from New Guinea and adjacent islands
Abstract
Two new species of the genus Mikluchomaklaia Gorochov, 1986 are described in the nominotypical subgenus: M. (M.) chuрini sp. n. from Waigeo and Gam islands near the western coast of New Guinea, and M. (M.) glupovi sp. n. from the southern part of New Guinea. These species differ from other representatives of this subgenus in shorter male tegmina and some features of the male genitalia, and from each other, mainly in the male genitalia characters.
