Abstract:

Sampling of litter samples was carried out on broiler and parental poultry farms with different age stages of cultivation. The ecological features of formation of populations of synanthropic species of beetles are investigated. The influence of insecticides on the kind of darkling beetle is shown as one of the methods of preventing the spread of their population. In the course of research it is shown that the microclimate of the poultry house and high temperatures are optimal for the development of harmful entomological fauna. The distribution of beetle populations depends on the term of growing poultry and mechanical damage to the litter. It has been shown that insecticides are an optimal option to fight pests in poultry enterprises even in small doses. But due to their prolonged use, insects have developed resistance to drugs so they need to be changed with a certain periodicity which can be economically disadvantageous for the poultry industry and make significant financial expenses. The article outlines the probable ways of pests in broiler and parental poultry farms and the negative effects of their spread. Such species of beetles as were identified – Alphitobius diaperinus, Trogoderma  variabile and Sіtophhilus granaries The insecticidal effect of pyrethroid drugs on the species A. diaperinus is shown, optimal harmful concentrations are calculated Author Biographies Olga Tertychna, Institute of Agroecology and Environmental Management National Academy of Agrarian Sciences of Ukraine Metrolohichna str., 12, Kyiv, Ukraine, 03143 PhD, Senior Researcher Department of ecotoxicology Laboratory soil rehabilitation
