PEST MONITORING OF DISTRIBUTION AND HARMFULNESS OF NON-GREGARIOUS LOCUSTS ON FARMLAND IN NORTHERN KAZAKHSTAN

Abstract

Scientific paper discusses the results of research on pest monitoring of harmful non-gregarious locusts complex on agricultural lands of Northen Kazakhstan for 2013-2015. All identified 9 species of phytophagous often common in areas of Northern Kazakhstan. Particularly common species include Pararcyptera microptera (F.-W.), Dociostaurus brevicollis (EV.), Podisma
pedestris (L.) – they met on all cereal plots, fallow lands and pastures. It is established that on oil and bean cultures the number of insects was very low or absent. Basically, they inhabited habitats of perennial grasses, less frequently - cereals crops. Studies have shown that the harmfulness of this rests becomes economically significant when their numbers are > 10 ind./m2 . In this case it is
recommended to apply phytosanitary measures against harmful non-gregarious locusts complex.
