The range of invasive mosquitoes is constantly expanding. During entomological monitoring of the Black Sea coast of the Caucasus, mosquitoes Aedes aegypti, Aedes albopictus and Aedes koreicus are carriers of arbovirus diseases dangerous to humans.

The fauna of hemipopulations of adult ixodid ticks on five islands of the Peter the Great Gulf (Primorsky Krai) has been studied. Contemporary data on the population of the complex of their species are compared with materials from the work of G.V. Colonin (1986). In just two comparable observation periods on the islands by flagging of vegetation seven of the same species of ixodid ticks have been collected: Ixodes persulcatus, I. pavlovskyi, Haemaphysalis japonica, H. concinna, H. longicornis, H. flava, Dermacentor silvarum. On all islands without exception, I. persulcatus was previously and now found, although the species is not always dominant, sometimes rare. No directional changes have been revealed in the representation of H. japonica, H. concinna and D. silvarum on the islands, which are common species for the mainland of Primorye. A decrease in the occurrence of I. persulcatus and an increase in the occurrence of I. pavlovsky have been noted. In some areas of sympatry zones of these species, the latter becomes dominant. H. longicornis occurs in large numbers only on the island of Askold, where sika deer continue to live. The data obtained allow us to assert that the southern species H. flava is gradually spreading the territory of Primorye. Based on the established complex of ixodid tick species on the islands of Peter the Great Gulf, in order to prevent cases of tick-borne infections in humans, it is necessary to strengthen nonspecific prevention measures, in particular, carrying out acaricide treatments in places where vacationers are accommodated and planned mass events, usage tick-proofing clothes.

The aspects of the analytical definition of the most common group of insecticidal preparative forms, which are conventionally combined under the term «liquid», are considered. These can confidently include emulsion and suspension concentrates (micro-encapsulated products, due to their specificity, are considered separately), as well as ready-to-use solutions of substances. Using concrete examples, the possibilities of using chromatographic methods (RP HPLC, GC) in the analysis of the most common groups of insecticidal substances (neonicotinoids, POS, pyrethroids, carbamates) and synergists (piperonyl butoxide, MGK 264) are considered. UV spectra (220-340 nm) were demonstrated for each of the 14 substances considered. Information is provided that allows relatively quickly, within the framework of a harmonized approach, to develop an analytical method based on an available chromatographic method or to identify the facts of falsification of products. The work is a continuation of a series of studies aimed at solving methodological issues of creating techniques and their correct implementation into the quality management system at enterprises specializing in the field of «pest control».

In Russia, as in most countries of the world, there are territories that can be classified as special ecological and epidemiological geographical areas that require increased attention to sanitary protection from imported and endemic infectious diseases. The Black Sea coast is one of such territories our country. Epizootically significant biotopes and habitats of blood-sucking mosquitoes Aedes aegypti and Aedes albopictus based on the results of long-term epizootological monitoring were identified. Their epidemiological significance in different countries is shown. The algorithm for improving the antimosquito measures tactics and the performance evaluation of the insecticidal treatments using modern means and methods of disinsection are presented.
