Dark melolonthidae sex pheromone and sex attractant

Abstract

The invention discloses a dark melolonthidae sex pheromone and a sex attractant. The sex pheromone comprises the following components: L-isoleucine methyl ester, (R)-(-)-linalool and 1-cyclohexane amino acid with the weight ratio of 2-9:1:0-1. The sex attractant comprises the dark melolonthidae sex pheromone and organic solvents; and the weight ratio of the sum of all components in the dark Melolonthidae sex pheromone and the organic solvents is 1:2.2-100. The dark melolonthidae sex pheromone is beneficial to protecting natural enemies, benefiting and eliminating pests, giving full play to integrated control power and improving the control effect when being used for forecasting insects and preventing dark melolonthidae pests by using a trapping method and an interference mating method; and in addition, the application of chemical pesticides is avoided so as to reduce the pollution, protect the environment and ensure remarkable economic benefits, social benefits and ecological benefits. The invention is suitable for the control of the dark Melolonthidae pests in farmlands.

Description

technical field [0001] The invention relates to an insect sex attractant, in particular to a black beetle sex pheromone and the prepared sex attractant. Background technique [0002] Grubs are one of the most important underground pests that harm crops. Because they are harmful underground, they have high requirements for pesticide application methods, duration of efficacy, and pesticide residues. Therefore, grub control is a recognized problem at home and abroad. Existing chemical agents are difficult to meet the above requirements simultaneously. Adult grub beetles come out of the ground in the evening to feed, and this opportunity can be used to prevent and control the adults, so as to achieve the goal of eradicating scarabs and exterminating larval grubs under the premise of high efficiency and environmental protection. Among the many kinds of scarabs, the black beetles occur in a large amount in various dry fields, and are the dominant species among the scarabs. Theref...

Although hundreds of insect sex attractants have been used at home and abroad, so far there is no report on the field application of the sex attractant of the black beetle. Qu Mingjing applied for a kind of black beetle in the Chinese patent application number 200810211798. method for the isolation and identification of sex pheromones, but did not clearly describe the sex attractant components of the black beetle
