(2) The generational differentiation of longhorn beetles is relatively complicated, and the general generation is long, with a life cycle of more than one year. Due to the huge differences in the niches in which individuals live, their life history is changeable and complicated, which has caused great harm to the control work of longhorn beetles. great difficulty
[0004] 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 longicorn beetle is a kind of boring pest, and biological control agent is difficult to reach the adult and larva of longicorn longicorn; 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
When spraying, the amount of medicine is large, and the droplets will drift with the wind. It is necessary to use high-pressure spraying machinery, and it is difficult for the medicine to reach the insect body effectively, and the utilization rate of the medicine is too low
The poison swab method needs to find the openings 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 the tree is damaged after drilling, and the self-healing of the tree The capacity is limited, and most of them will be rotten. Farmers have certain difficulties in accepting this method

Abstract
The invention discloses high-efficiency longhorn beetle control paste with strong intake transportation characteristic and contact toxicity, and belongs to the field of pesticides and preparations thereof. The paste is prepared by blending the following components in percent by weight: 0.1-30% of thiacloprid, 0.1-20% of 2-phenyl-1-(5-(2-phenylethynyl)thiophene-2-yl) ethyl ketone (hereinafter referred to as PPTE) and the balance of additives. The additives comprise a solvent, an adhesive and filler, wherein the weight of the solvent, the adhesive and the filler respectively accounts for 0.1-80.0%, 0.1-80.0% and 0.1-80.0% of the total weight of the paste. The invention further discloses an application method of the paste; and when the paste disclosed by the invention is applied to the part where bark is peeled off, good adhesion and persistence are realized; pesticide application is simple and convenient; insecticide utilization rate is improved; environmental pollution is reduced; an insecticide can enter into plants through internal absorption of plant epidermis; and the paste disclosed by the invention has a certain contact toxicity so as to prevent pests from crawling up and downon a tree trunk, thus greatly reducing harm to trees.
Description
technical field [0001] The invention relates to a high-efficiency, systemic conduction ointment for controlling long beetles and a method for using the same, belonging to the field of pesticides and preparations thereof. Background technique [0002] Beetle is an important borer pest of poplar, willow, elm, maple and other tree species in my country. There are more than 100 kinds of beetles reported in China. Due to the secluded life of longicorn beetles, few types of natural enemies, and complex life history, poplar and willow are 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 longicorn beetles and serious harm to longicorn beetles in my country. , with an annual area of 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 restr...
