The material is exposed on 222 pages and consists of introduction, 5 chapters, conclusions and recommendations, bibliography, which comprises of 265 sources and 2 annexes. The dissertation includes 52 tables and 36 figures. The results are published in 63 scientific works.
Field of study: 06.01.11 – plant protection.
Aim. Appraisal of ethological and physiological aspects in determination of action mechanism of sexual pheromones on ontogenetic cycle of species of target insects and elaboration of an application strategy for their decrease in population density by means of mass trapping and disorientation of males.
Objectives. Appraisal and classification of stages of sexual behavior of insect species with hidden life-style and determination of appeared impact under the action of medium saturated with sexual pheromones on them, arguing the disorientation process theoretically and practically.
Scientific novelty and originality. Determination of the mechanism of pheromone influence on ontogenetic cycle of insects with hidden life-style; identification and classification of stages of sexual behavior; identification of factors and physiological modifications which reduce the female fertility under action of pheromones; identification and determination of role of aphrodisiac pheromones in the course of process of sexual behavior; elaboration of estimation criteria of mass trapping and disorientation of males.
Scientific problem consists in appraisal of ethological, phisiological features and descryption of action mechanism of synthetical sexual pheromones analogoues on ontogenetic cycle of target insects species and elaboration of their application strategy for descrease of population of insect pests when applying the mass trapping and males' desorientation methods.
Theoretical significance. For the first time there was argued the disorientation method of males and was carried out the appraisal of the mechanism of pheromone action on ontogenetic cycle of insects with hidden life-style. The obtained results shall serve as a basis for interpretation of the mechanism of pheromone action in the course of disorientation methods and mass trapping of males, assuring the decrease in density population of target insects.
Applied value of work. This study represents an effective base for application of synthetic sexual pheromones in integrated protection of plants for the purpose of obtaining a competitive crop and regeneration of a natural balance in agrobiocenosis.
Implementation of scientific results. Elaborated methodological and technological methods have been introduced in protection of cabbage, tomato cultures and plum gardens.
