Herd locusts.
More than 270 species of locust insects live in Kazakhstan, of which 10-15 species are dangerous pests of grain, vegetable crops, pastures and hayfields. The most dangerous and harmful are the herd species of locusts - Asian, Moroccan and Italian Prussian. Herd locusts have a constant tendency to group into groups (clusters of larvae) and swarms (clusters of adults) and live crowded. Kuligi and stai perform migration over considerable distances. Herd locusts can cause serious harm and endanger the food security and livelihood of the local population. The complexity of anti-locust treatments is that it is difficult to predict their invasion.
Italian Prussian is a pest that is widespread in Kazakhstan, but it has the largest concentration in northern and western Kazakhstan. Inhabits areas of cereal-sage, often sandy steppes of the steppe and desert zone of Kazakhstan. This is a very ecologically plastic species, capable of easily adapting to different habitats. The preferred fodder plants are mostly forages, although almost all crops, including cereals, can be damaged during outbreaks. Spawning occurs from the end of April to the middle of June. Larva development lasts 40-55 days and passes through five instars. Adult insects are usually present from the beginning of July. Mating from July to August to September. Females lay one to four eggs (up to 120 overwintering eggs) in dry, weedy soils, as well as in loose, dry soils. Adults die at the end of summer.
Asian locust - brown or green imago 29-55 mm long, gregarious species. Eggs overwinter in cups in the soil at a depth of 5-6 cm. Nymphs emerge in the spring and come to the surface of the soil. They develop in 35-50 days. Fertility of the female is 60-80, sometimes 120 eggs (2-3 cubes). Nymphs of the form of a herd form agglomerations, which can cover large distances - 45 km.
In 2025, the monitoring survey of herd locusts in the territorial inspection of B. Mailina district will amount to 152 thousand hectares. Of them, according to Italian Prussia, the total survey area is 102.0 thousand ha. of them, 1.0 thousand ha - spring cubs, 50.0 thousand ha - spring-summer larvae, 50.0 thousand ha summer imago, 1.0 thousand ha - autumn cubs. 50,000 ha of Asian locusts to be surveyed. There are 30,000 ha of larvae from them. Imago 20.0 thousand ha.
By 2025, the projected volume of locust cultivation is 1.0 thousand ha on state reserve lands, of which Belinsky village - 0.2 thousand ha, Novoilinovsky village - 0.4 thousand ha, Kalininsky village - 0.3 thousand ha, Ayet village - 0.1 thousand ha.
When fighting locust larvae, the main target and treatments against them are carried out in the spring. Treatments can also be aimed at cubs (early spring) or imago (late spring and summer). Mechanical and agrotechnical measures are sometimes used. Spraying with chemical preparations (insecticide) is the main method of combating locusts. It is mainly carried out by land and air. Different methods of processing are used against locusts: continuous - the entire territory inhabited by the pest is treated; barrier - certain strips are processed in the direction of movement of locusts, leaving the interbarrier space without processing; local - treated only the foci of accumulation (coolies) of larvae; regional - are performed around the crops of agricultural crops.
