The recent rapid rise in temperature has moderate rainfall, and the population density of the Citrus spider has increased rapidly and appears to be overweight. From April 25 to 27, local surveys showed that the occurrence of spider mites was generally more than 10 per leaf. For example, the number of leafhoppers in Xibiantang Village, Xiaotang Township was 6.7 (1 to 18), and the number of red leafhoppers per leaf was 50. Above; 22.13 per leafworm in Dilong Village, Dingtang Town (2~50 heads); 1.8 leaf per leafhopper in Xiaobaizhang Village, Hepu Town, 48 eggs per leaf (8~232 grains). The individual re-issued Orange orchards at Xiashan Village, Danxi Street, etc. have a total of 84.25 leafhoppers (17 to 150 heads). With the growth of citrus shoots, red spiders gradually spread to new shoots, and the damage will be further exacerbated. At the same time, part of the orange larvae are also harmful to young shoots. For this purpose, the local farmers are urged to intensify their inspections. For orange groves with an average population density of 10 or more per leaf, they should be treated with pesticides in a timely manner. The control agent can be used for 15% of Fuling EC 1500 times, or 1% of A. EC 4000 times liquid spray. The control of aphids can be sprayed with 10% imidacloprid 3000 times solution. It is currently at the flowering stage of citrus, and special attention should be paid to science and safe drug use.
