Due to the fact that the Republic of Karakalpakstan is situated in the northern part of Uzbekistan, where the climate is sharp and the territory is extra-arid, changes of ecological factors in recent years, in the first place bringing into the decrease of the amount of plant types, yields of agricultural crops, which are being sown in the biotopes. As a result, rapid change of pest types of agricultural crops, which appear in biocenosis, was being observed. While the process of extinction of some types is appeared, there is an opportunity for rapid appearance of types, which did not exist in the past and coming into the ranks of the main pests. It is required to indicate these types of pests as inner and outer quarantine object and carrying out controlling actions in order to prevent them from spreading. Although these types of pests are appearing in the region in recent years, it can be stated as an example potato moth, which is damaging potato and tomato moth, which is the main pest of potato. Nowadays, it is an actual problem to create scientific basics of controlling actions which influence in maximum degree by defining biological peculiarities, developing dynamics, damaging degree in order to carry out effective controlling actions of the types which are spread in the agrobiocenosis.
