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 means of trapping large quantities of semiochemicals combined with traps, and in particular relates to an attractant for tea geometrid adults and a method for preparing lure cores containing the attractant. Background technique [0002] tea inchworm ( Ectropis obliqua Prout (=Boarmia obliqua hypulina Wehrli)), belonging to Lepidoptera, Geometridae, is one of the important tea tree pests in my country. Serious outbreaks 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 belongs to the stripe aggregation distribution type, with 6-7 generations per year, serious generation overlap, large egg production, and often occurs in large numbers. When it is serious, the branches and stems will be bare, and the third an...

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
