Problems solved by technology
[0007] The difficult problem that above each method faces is that the biological control effect is unstable, and the control effect is affected by factors such as weather, and poplar longicorn beetle is a kind of boring pest, and biological control agents are difficult to reach the adults and larvae of longicorn beetle; Chemical control methods are used in large areas, such as poison swabs, drilling injections, burying drugs, spraying, etc., but these methods encounter great difficulties in the control effect or specific implementation
The poison swab method needs to find the holes of longhorn beetle larvae and adults, and the workload is too large for large-scale control; the workload of drilling and injection is too large for large-scale control, and the xylem of poplar is damaged after drilling. The self-healing ability is limited, and most of them will be rotted. Farmers have certain difficulties in accepting this method; when spraying, the dosage is large, and the droplets will drift with the wind. High-pressure spraying machinery is required, and the medicine is also difficult. Effectively reach the worm body, the utilization rate of the medicine is too low

Abstract
The invention relates to ointment for preventing and treating poplar longhorned beetles, and belongs to the fields of pesticides and preparations thereof. The insecticidal ointment containing the photoactivation insecticide 2, 5-bithienyl-2-thiophene acetylene is prepared by blending 0.1-40% of 2, 5-bithienyl-2-thiophene acetylene, 0.1-40% of thiacloprid and the balance of additives in percentage by total weight of the insecticidal ointment, wherein the additives comprise 0.1-80.0% of solvent, 0.1-80.0% of adhesive and 0.1-80.0% of packing in percentage by total weight of the insecticidal ointment. The insecticidal ointment is long in lasting period and simple and convenient to operate and has low pollution to environments. The insecticidal ointment is applied to stripped barks, has good adhesive force and persistent effect and is simple and convenient to apply; the utilization rate of the ointment is increased; the environmental pollution is reduced; and the insecticidal ointment can be absorbed in plants and has certain contact action.
Description
technical field [0001] The invention relates to an ointment for preventing and controlling poplar beetle pests, and belongs to the field of pesticides and preparations thereof. Background technique [0002] Poplar longhorn beetle is an important borer pest of poplar, willow, elm, maple and other tree species in my country. More than 100 species of poplar longhorn beetle have been reported in China. Due to the hidden life of poplar longhorn beetles, few types of natural enemies, and complex life history, poplar is one of the preferred tree species for afforestation in my country, such as afforestation, windbreak and sand fixation, fast growth and high yield, resulting in sufficient food resources for poplar longhorn beetles. The occurrence area is 600,000 hm 2 about. In the past 10 years, the macular beetle and the bare-shouldered beetle have spread rapidly and caused serious damage, which has greatly restricted the development of poplar trees and seriously affected the heal...
