Tea geometrid imago attractant and preparation method of lure with same

Abstract

The invention discloses a tea geometrid imago attractant and a preparation method of a lure with the attractant, belonging to the technical field of prevention and control of pests by means of large-quantity trap with the combination of information compounds and trappers. The attractant comprises the following ingredients in parts by weight: 0.5-40 parts of cis-3-hexene butyrate, 1.5-120 parts of benzyl alcohol, 0.5-240 parts of cis-3-olefine aldehyde, 0.001-0.2 part of 2,6-bitertiary butyl p-cresol and 0.001-0.2 part of 2-hydroxy-4-methoxy-benzophenone. The tea geometrid imago attractant disclosed by the invention is reasonable in compatibility of medicines, and can effectively trap, prevent and control tea geometrids; the tea geometrid imago attractant adopts a polyethylene sustained-release bottle, so that effective components can be slowly and uniformly released, and the lasting period is prolonged. Due to an antioxidant and an ultraviolet absorbent added into the tea geometrid imago attractant, the components of the attractant are effectively prevented from oxygenolysis by factors of external air, light, ultraviolet light and the like. Therefore, the attractant is a tea geometrid imago attractant with persistent effects.

Description

technical field [0001] The invention belongs to the technical field of preventing and controlling pests by using semiochemicals combined with traps for a large number of trapping methods, and particularly relates to a tea inchworm adult attractant and a method for preparing a lure core containing the attractant. Background technique [0002] Tea looper ( Ectropis obliqua Prout (=Boarmia obliqua hypulina Wehrli)), belonging to Lepidoptera, Cyclopidae, is one of the important tea tree pests in my country. Serious occurrences have occurred in tea gardens in Jiangsu, Zhejiang, Anhui, Fujian and Henan provinces. In addition to harming tea trees, it also harms plants such as cherries, pomegranates, maple poplars and soybeans. In the field, it is a striped aggregation distribution type, with 6-7 generations per year, serious overlapping of generations, large spawning, and frequent occurrence. In severe cases, the branches and stems will be bare, the third and fourth teas cannot...

Problems solved by technology

Unfortunately, although the research on sex pheromones of tea geometrids started earlier, the existing pheromone components have an unsatisfactory effect on trapping adults of tea geometrids in the field, and sometimes they are completely ineffective. An embarrassing situation that cannot be directly applied to prevention and control
