Embodiment 1

[0016] Accurately weigh 0.4 g of L-isoleucine methyl ester, 0.2 g of (R)-(-)-linalool, 0.1 g of 1-aminocyclohexanecarboxylic acid and (9Z, 12Z, 15Z )-octadecatrienal 0.3 gram, dissolves in 3 gram ethyl acetates. After pulverizing 5 grams of castor leaves, 5 grams of elm leaves and 5 grams of hawthorn leaves, soak them in 12 grams of ethyl acetate solution at 40 degrees for 3 hours. Put a mix of sex and food attractants into the trap. Phosphor powder was sprayed on the trap, and 25 unmated female adults of the black beetle were fixed on the trap at the same time.

Embodiment 2

[0018] Accurately weigh 0.4 g of L-isoleucine methyl ester, 0.2 g of (R)-(-)-linalool, 0.1 g of 1-aminocyclohexanecarboxylic acid and (9Z, 12Z, 15Z )-octadecatrienal 0.3 gram, dissolves in 3 gram ethyl acetates, puts into the trap after mixing evenly, and the trap does not do extra treatment.

Embodiment 3

[0020] After pulverizing 5 grams of castor leaves, 5 grams of elm leaves and 5 grams of hawthorn leaves, soak them in 12 grams of ethyl acetate solution at 40 degrees for 3 hours. After mixing evenly, put it into the trap, and the trap will not be treated additionally.

Abstract

A method for improving the attractive effect of a Holotrichia parallela sex attractant is characterized in that the sex attractant is combined with a food attractant, a light attractant and a shape attractant to attract male Holotrichia parallela in a synergistic manner, so defects of single attractants are avoided, the attractive effect is greatly improved, and Holotrichia parallela in peanut fields is well controlled.

Description

technical field [0001] The invention discloses a method for improving the lure effect of a black beetle sex attractant, which belongs to the technical field of biological control methods for peanut pests. Background technique [0002] Grubs are the most serious underground pests that harm peanuts. 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. It is difficult for chemical agents to meet the above requirements at the same time. Adult grub beetles come out of the ground in the evening to feed. In line with the principle of "underground pest control on the ground", this opportunity can be used to prevent and control adults, and achieve the goal of eliminating beetles and making larvae grubs extinct under the premise of high efficiency and environmental protection. Among many kinds of scarabs, the black beetle is...
