A white star beetle aggregation pheromone and its application method

Abstract

The invention discloses a protaetia brevitarsis aggregation pheromone. The protaetia brevitarsis aggregation pheromone consists of the following components in percentage by weight: 1-8% of heptanone,1-6% of nonanone, 62-79% of 4-methoxytoluene and 14-25% of 4-methoxyacetophenone. According to the protaetia brevitarsis aggregation pheromone and a using method thereof, the usage amount is very small, an obvious attracting effect is achieved on both female and male adults of protaetia brevitarsis, and the protaetia brevitarsis aggregation pheromone are environmentally friendly and are free of pollution.

Description

technical field [0001] The invention relates to the technical field of prevention and control of agricultural pests, in particular to an aggregation pheromone of the white star beetle and a method for using the same. Background technique [0002] White star beetle (Protaetia brevitarsis Lewis), also known as white-patterned copper beetle, white star flower potential, white star beetle, and copper gram beetle, is a pest of the Coleoptera flower beetle family. It is distributed in most provinces in northern my country. Foreign countries are mainly distributed in Mongolia, North Korea, Japan and Russia. Adult white star beetles have mixed feeding habits, and often gather in the fruits of grapes and other fruit trees, field crops such as corn, and flowers and leaves of willows and other trees, seriously affecting the yield and quality of agricultural products and fruit trees, and bringing great losses to agricultural and forestry production.

Problems solved by technology

Adult white star beetles have mixed feeding habits and often gather in the fruits of fruit trees such as grapes, field crops such as corn, and flowers and leaves of trees such as willows, seriously affecting the yield and quality of agricultural products and fruit trees, and bringing great losses to agricultural and forestry production.

[0003] At present, there are reports on the use of chemical pesticides to prevent and control the white star beetle, but the peak period of the insect's damage coincides with the ripening period of agricultural products, and the use of pesticides for prevention and control is likely to cause pesticide residues and pollution

Moreover, because adults have a strong ability to fly, they are easy to escape during the application process, reducing the effect of chemical control.

In addition, fruit growers also use sweet and sour liquid to trap the insects, but the effect is not ideal
