Abstract

The invention relates to the technical field of pest control, and particularly discloses a control method of drosicha contrahens. The control method includes the following steps: in late January, annular drug segments of a high-chlorine.imidacloprid agent are sprayed on the surfaces of tree trunks, in early February, pest sticking adhesive tapes are wound around the middles of the annular drug segments closely attached to the tree trunks, the number of live drosicha contrahens between the lower edges of the pest sticking adhesive tapes and the lower edges of the annular drug segments is observed at fixed period, and when the number of the live drosicha contrahens is greater than 1/100 cm<2>, a sophocarpidine agent is sprayed additionally in time. According to the control method of the drosicha contrahens, a comprehensive control measure combining physical blocking and chemical control is adopted, the control effect is achieved to be 98% or above, the base number of the drosicha contrahen population in the year is effectively decreased, operation is easy, convenient and feasible, the material cost is low, the environmental pollution problem is avoided, safety of people and animals is achieved, and the good economic, social and ecological benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a control method for Paramecia. Background technique [0002] Paramecia, also known as paramecium and mulberry louse, is an insect belonging to the genus Paramecia in the family Cottonidae of Hemiptera. Paramecia is an omnivorous piercing-sucking insect, which mainly harms the branches, trunks and buds of ash, locust tree, Chinese toon tree, willow tree, cherry blossom and other flowers and trees, and also harms economic tree species such as peach tree, jujube tree and apricot tree. The nymphs and adults of Paramecium often gather on the branches and trunks of plants to pierce and suck the juice, destroying the nutrition of the host, causing the trees to grow weak, the leaves to turn yellow, the branches to dry up, and even the whole plant to die. The mucus secreted by them can easily pollute the branches and roads , Greatly destroy the achievements of urban greening and ci...
