Attractant composition for dioryctria abietella and application of attractant composition

Abstract

The invention discloses a dioryctria abietella attractant composition and application thereof. The dioryctria abietella attractant composition is prepared from dioryctria abietella sex pheromone and a synergist, the sex pheromone is prepared from cis-9, trans-11-tetradecadiene acetate, cis-3, cis-6, cis-9, cis-12, cis-15-pentacosapentaene, and the synergist is one or more of alpha-pinene, beta-pinene and ocimene. The attractant composition provided by the invention can greatly improve the trapping amount of the male bioryctria abietella, effectively interfere with the mating of the male and female bioryctria abietella, and reduce the probability of harm to offspring. The attractant composition provided by the invention has the advantages of easily available raw materials, convenience in use and environmental friendliness, can be accurately applied to insect situation forecasting, mass trapping and killing and mating interference, and has important significance on green prevention and control of dioryctria abietella.

Description

technical field [0001] The invention relates to the technical field of biological control, and in particular relates to an attractant composition for preventing and controlling A. fir. Background technique [0002] Dioryctria abietella, also known as Korean pine cone borer and pine cone borer, belongs to Lepidoptera, Moth family, and is an important pest of the main shoots and cones of Korean pine in Northeast China. Domestically, it is mainly distributed in Heilongjiang, Jilin, Liaoning, Beijing, Shaanxi, Jiangsu, Zhejiang, Hubei, Hunan, Sichuan and other places; abroad, it is mainly distributed in the Czech Republic, Poland, Finland, the Soviet Union, the United States, Canada, North Korea, Japan, etc. Damaged tree species are Korean pine, fir, masson pine, slash pine, loblolly pine, spruce, Siberian Korean pine, Pacific silver fir. The larvae mainly damage the biennial cones and twigs of Korean pine, and eat the fruit axis, seeds and fruit scales, causing some cones to f...

AI Technical Summary

Problems solved by technology

The larvae mainly harm the twigs of the two-year-old cones of Korean pine, eating the fruit axis, seeds and scales, resulting in some cones falling off and necrotic, resulting in a sharp drop in the quality and yield of Korean pine seeds, trunk bifurcation, material and yield rate Significant decline, seriously affecting the economic benefits and ecological construction of the forest area

It is difficult to control the larvae of the fir moth larvae due to the hidden location, short exposure time, and irregular eclosion period of adults.

[0003]Traditionally, chemical pesticide control and light trapping are mostly used; biological control methods such as parasitoid wasps of the family Adenidae are used; however, chemical pesticides are used, and the control effects are washed away by rain And the decomposition of ultraviolet rays in the sun will be rapidly reduced, and the Korean pine seeds are precious medicinal materials in our country. Spraying a large amount of pesticides will produce residues that will affect human health and pose a threat to the safety of humans and the environment.
