RESULTS OF THE RESEARCH OF DYNAMICS OF NUMBER OF THE MAIN WRECKERS ON LANDINGS OF THE TOMATO IN THE SOUTHERN KAZAKHSTAN AREA
In this article results of researches of studying of bioecological features of the main wreckers of a tomato are given in the Southern Kazakhstan area. By researches it is established to regularity of dynamics of number cotton scoops and plant louses on landings of a tomato in 2016–2017: the largest number cotton scoops is noted twice – the first in the 1st decade of July, the second – in the 3rd decade of August; it is possible to call settling of plants of tomatoes a cotton sovka rather uniform; the peak of number of the wrecker was observed from the moment of emergence of fruits – in June and July; the population of landings of tomatoes caterpillars cotton scoops was from 47,2 to 54,5 percent from total of plants; the average density of caterpillars on landings of tomatoes was from 1,1 to 1,5 copies on a plant. Results of studying of dynamics of number of a peach plant louse: the first individuals of winged plant louses appeared on landings of tomatoes in May, in June number increased, the peak of number was noted in July, so in 2016 – 25 individuals, in 2017 – 30 individuals; larvae of a wingless peach plant louse have been registered on plants of tomatoes in 1 – 2 decades of June, and mass reproduction was noted also twice – it is in 3 decades of July and in 1-2 decades of August. Results of studying of bioecological features of the main wreckers of tomatoes of the Southern Kazakhstan area – cotton scoops and plant louses can be used for development an action for protection of the tomatoes which are grown up in the Southern Kazakhstan area.
