The reporter learned yesterday that according to the information on diseases and insect pests released by the Hohhot Plant Protection Station, recently, with the rise in temperature, locust eggs in the capital locust area have begun to hatch in large quantities, of which Wuchuan County has entered the peak period of locust excavation and has begun to spread. Up to now, the area of locust occurrence in the city has reached 1 million mu.
It is understood that on May 18, Wuchuan County monitoring personnel in Erfenzi Township Heisha rabbit village, West Ulan Bulang Town Shuiquan Village, Shangwuhai Township Baishanzi and other natural villages around the grass beach found that locusts are in the peak of excavation, and a large area of spread, the general insect population density of 10 to 20 heads / square meter, the highest density of 40 heads / square meter. In the grassy beaches around the farmland in Qingshuihe County, the density of locusts is 3 to 4 heads/square meter, and the highest density is 5 heads/square meter. Helin County occurred in Heilaoyuan, Xindianzi, Yangqungou and Chengguan Town, and the locust density was 0.8 heads/square meter. At present, the locusts in the grassland of the desert beach in Wuchuan County have reached the control target. By late May, as temperatures rise rapidly, locusts will continue to emerge in large numbers, the density of insect populations will continue to increase and will spread rapidly, and crops that are in the early stages of emergence will be threatened. In this regard, the agricultural department reminded that it is expected that the end of May to the beginning of June is the right period for locust control, and all flag counties and districts should strengthen monitoring, use radio, television, newspapers and other media to do a good job in prevention and control technical guidance, at the same time, we must give full play to the role of local specialized prevention and control organizations, use large-scale pesticide application equipment to carry out ground emergency prevention and control and professional unified prevention and control, and prevent its spread to farmland as a harm.
