Trapping device with composite insect sex pheromone lure and application thereof

Abstract

The invention relates to the technical field of pest prevention and treatment, and aims to provide a trapping device with a composite insect sex pheromone lure and an application for the trapping device. Key points of a technical scheme of the invention are as follows: the trapping device comprises a trap body and the composite sex pheromone lure arranged in the trap body, wherein the composite sex pheromone lure comprises a shell and a composite sex pheromone carrier arranged in the shell; and the compound sex pheromone comprises the following components in parts by weight: 50 to 70 parts ofcis 11-octadecenal, 400 to 600 parts of cis 13-octadecenal, 50 to 70 parts of cis 11-octadecenol, 80 to 200 parts of cis 13-octadecenol, 40 to 50 parts of cis 11-hexadecenal, 20 to 60 parts of cis 9-hexadecenal, 60 to 80 parts of linalool, 40 to 60 parts of (E)-alpha-bergamotene, 100 to 200 parts of a vetiver grass extracting solution, 1 to 3 parts of an antioxidant and 2 to 5 parts of an anti-ultraviolet agent. The trapping device with the compound insect sex pheromone lure provided by the invention is applied to insect and pest prevention and treatment for rice borer, chilo suppressalis andcnaphalocrocis medinalis. The trapping device provided by the invention has the advantages of large prevention and treatment range, good prevention and treatment specificity and high prevention and treatment effects.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a trapping device with a compound insect pheromone lure core and an application thereof. Background technique [0002] Insect pheromone is a general term for compounds used for communication between insects, and is a chemical molecular language for communication between insects. Pheromones can be divided into different types, which can cause certain behavioral responses of other individuals, including functions such as mating, spawning, gathering, and alarming. Among them, the pheromones used to attract mating between male and female insects of the same species are called sex pheromones (also called sex lures), which are highly specific and sensitive. [0003] Traditional plant pest control is mainly carried out by chemical pesticides. Although chemical pesticides have the advantages of high efficacy and easy large-scale spraying application, their toxicity, environmental p...

Problems solved by technology

[0006] Although the technical scheme of the above-mentioned existing patent 1 increases the number of female moths of the rice leaf roller to reach the information source by enhancing the antenna potential (EAG) response of the female and male moths of the rice leaf roller to the sex pheromone, but in actual use During the process, since the rice pests include the rice borer and the rice stem borer in addition to the rice leaf roller, a single rice pest attractant cannot control a variety of rice pests in a wider range, and the control effect is low;

[0007] Although the technical solution of the above-mentioned existing patent 2 realizes the effect of trapping phototactic pests through the cooperation of insect trap lamps and power grids, the trapping of single light source is not specific enough for trapping pests, and is not suitable for large-scale rice field pests. prevention
