Artificial repellent for monochamus alternatus

Abstract

The invention provides an artificial repellent for monochamus alternatus, which belongs to the technical field of controlling of insects. The artificial repellent is characterized by containing 8 to 19% of active components, 5 to 12% of synergistic components, 2 to 11% of a stabilizing agent and 63 to 81% of a solvent. Through mutual synergism of a plurality of the active components which have good repellent effects, the artificial repellent for monochamus alternatus provided in the invention can substantially repel monochamus alternatus larvae boring into pine trees and monochamus alternatus adults on the surface of pine trees; therefore, carrying and propagation of pine wood nematode by the pine trees can be mitigated, the survival rate of the pine trees can be increased, overflowing of pine wood nematode can be effectively controlled, and a transmission source can be cut off. Production process for the artificial repellent is simple and convenient, and monochamus alternatus does not generate resistance even under the condition of long-term usage of the artificial repellent; and the artificial repellent has the advantages of a good repellent effect, low production cost and suitability for large-area sprinkling usage in a pine forest.

Description

technical field

[0001] The invention belongs to the technical field of insect control, in particular to an artificial monochamus alternatus repellant. Background technique

[0002] Monochamus monochamus is an important forest pest, and it is mainly distributed in Jiangsu, Anhui, Zhejiang, Guangdong, Shandong, Taiwan, Hong Kong and other places in China. Monochamus alternata is also the main vector insect of pine xylophilus, and pine xylophilus disease is a devastating disease of pine trees. At present, the common damage of monochamus monochamus and pine wood nematode has caused the death of a large number of pine trees.

[0003] Some people have studied the repellent substances of Monochamus alternatus. Hexane extracts of the hindgut of female monochamus alternata were found to contain chemicals that have repellant effects on oviposition. α-pinene, β-pinene, myrcene, 3-carene, limonene, terpinolene, and 4-methyl-2,6-di-tert-butyl were identified in extracts from the hindg...
