[0032] 1 Materials and methods

[0033] 1.1 Tested insects and reagents

[0034] Insects to be tested: the black beetles were collected from the experimental base of Peanut Research Institute, Laixi Wangcheng, Qingdao City, Shandong Province. After the collected adult black beetles were separated from males and females, they were reared with fresh elm leaves in incubators with ventilation holes respectively. The soil humidity in the incubator was kept between 18% and 20%. The insects to be tested were starved for 24 hours before the test.

[0035] Reagents for testing: The reagents used in the test were purchased from Sigma Company, and the purity of each reagent was above 95%. See Table 1 for specific reagents.

[0036] Behavioral response test equipment: (1) Antenna potential instrument is composed of micromanipulator INR-5, data acquisition controller IDAC-4, odor stimulation control device cs-05 and antenna potential recording and display output device, produced by Synt...

Abstract

The invention discloses an acetic acid cis-3-hexenyl ester synergistic holotrichia parallela sex attractant, wherein the weight ratio of the sex attractant and acetic acid cis-3-hexenyl ester is (3-7):1. The sex attractant comprises a holotrichia parallela sex pheromone component and an organic solvent, wherein the holotrichia parallela sex pheromone component comprises methyl L-isoleucinate, (R)-(-)-linalool and 1-aminocyclohexanecarboxylic acid in a weight ratio of 6: 1: 0.1 and the weight ratio of the holotrichia parallela sex pheromone component and the organic solvent is 1: 3. The organic solvent is one or more of dichloromethane, methanol or acetone. Behavior experiments show that EAG and selective reaction rate of male and female worms on a mixture of the sex attractant and acetic acid cis-3-hexenyl ester are relatively good. The field trapping experiments on holotrichia parallela show that acetic acid cis-3-hexenyl ester has a synergistic effect on the trapping effect of the sex attractant, thereby providing a ground for monitoring and preventing and treating holotrichia parallela by using plant volatile matters and insect sex pheromone in a synergistic manner.

Description

technical field [0001] The invention relates to an insect sex attractant synergized by plant source substances, in particular to a black gill beetle sex attractant synergized by cis-3-hexenyl acetate. Background technique [0002] The dark gill beetle (Holotrichia parallela) belongs to the Coleoptera (Coleoptera), Scarabaeoidea (Scarabaeoidea) gill beetle (Melolonthidae), and is an important class of soil-dwelling pests in agricultural, forestry and animal husbandry production. Its larval grubs harm peanuts, soybeans, sweet potatoes, corn, lawns, flowers, vegetables and other crops, often causing huge economic losses (Hu Qiongbo, 2004; Liu Shusen et al., 2008). Taking peanuts as an example, in recent years, the number of peanut grubs in all parts of the country has been increasing year by year, causing serious harm to peanut production. Generally, the damage is reduced by 10-20%, and severe cases are 50-80%, and even the grains are not harvested (Li Xiao et al. , 2012). Be...
