Grapholitha molesta sex pheromone efficient composite synergist and trapping application

Abstract

The invention discloses a grapholitha molesta sex pheromone efficient composite synergist and trapping application. The composite synergist is composed of E8, E10 dodecadienol, terpinyl acetate and acetic acid. The field trapping amount of the grapholitha molesta sex pheromone can be greatly increased, and the synergistic effect can reach 60% or above. The compound provided by the invention is non-toxic and residue-free, has no or less influence on non-target insects, and is beneficial to maintaining field ecology and promoting the development of green agriculture. According to the application trapping device, the advantages of a triangular trap and a basin type trap can be combined, the influence of the natural environment on traditional basin trapping is reduced, and the release time of a liquid attractant is prolonged.

Description

technical field [0001] The invention relates to the field of preparation of biological pesticide preparations, in particular to a high-efficiency composite synergist for sex pheromone of the pear borer moth and its trapping application. Background technique [0002] The small pear borer (Grapholitamolesta), also known as the Oriental fruit moth or the peach tip moth, belongs to the family Lepidoptera and is one of the main fruit-boring pests in the world. It mainly harms pears, peaches, apples, cherries, etc. It occurs most commonly in North China and Central China. The individual insects are small, with more fruit borers and a few generations. The number of annual reproductive generations is large and there are often overlapping generations. Because of its hidden moth shoots, host transfer, difficult control of traditional chemical pesticides, high residues, poor selectivity, and damage to the original ecology, it is contrary to the development of green agriculture in my co...

Problems solved by technology

[0005] Organic volatile terpineyl acetate (alpha organic volatile terpineyl acetate (dienol is codling) and acetic acid (acetic acid) are often used as the main component or additional component of traditional lure sweet and sour liquid, which itself has only a weak trapping effect. Insect ability, although the combination with sweet and sour liquid can improve the effect of attracting insects, but its volatile, poor stability, easy to trap non-target insects and other problems still limit the actual agricultural application

[0006] However, there is no report on the synergistic effect of using E8, E10 dodecadienol alone to lure insects or using a mixture of terpineol acetate and acetic acid as a sex pheromone synergist for pear borer worm, so we use the above substances as synergistic substances , studied their synergistic effect on pear small sex pheromone in the field, showing that the mixture of E8, E10 dodecadienol, terpineyl acetate and acetic acid has a significant synergistic effect on pear small sex pheromone
