Active composition based on camphor and n-octyl alcohol, chilo suppressalis attractant and application

Abstract

The invention discloses an active composition based on camphor and n-octyl alcohol. The active composition is prepared from the following components in parts by weight: 30 to 60 parts of the camphor, 15 to 50 parts of the n-octyl alcohol, 5 to 30 parts of nonyl aldehyde and 2 to 18 parts of linalool. The invention further provides a chilo suppressalis attractant composed of the active composition and a non-volatile organic solvent, and a chilo suppressalis lure for packaging the chilo suppressalis attractant in a mating disruption thread. The active composition disclosed by the invention can be used for directly luring female moths and male moths of chilo suppressalis; the control efficiency on the chilo suppressalis is higher than that of a sex attractant and the active composition can be used for trapping and killing a large amount of the chilo suppressalis, remarkably reducing the quantity of chilo suppressalis adults in the field and reducing the population density of descendants. The active composition also can be used for predicating the chilo suppressalis and the quantity of attracted and trapped insects can accurately predicate the population dynamic of the chilo suppressalis.

Description

technical field [0001] The invention relates to an attractant, in particular to an attractant for simultaneously attracting female and male moths of Chilo suppressalis. Background technique [0002] Insect attractant is an active substance produced by plants or artificially synthesized to attract specific insects. In the host selection process of insects, the special "fingerprint" volatile substances of plants often play a key role, and the effective components can be used for pest trapping and control. [0003] US 4880624 (A) describes the combination of such compounds as dimethoxybenzene, trimethoxybenzene or guaiacol with one or more of indole, phenylacetaldehyde, anethole, eugenol, cinnamaldehyde and cinnamonitrile. Application of the mixture as an attractant for the control of insects of the genus Rhizoma genus. US 4600581 (A) describes a synthetic pheromone active composition suitable for Spined Soldier Bugs, said active composition comprising a mixture of A-terpene ...

AI Technical Summary

Problems solved by technology

CN104782594 A discloses a compound attractant capable of simultaneously attracting both female and male moths of Chilo suppressalis, but the attractant still needs the cooperation of a sex attractant to achieve a good attractant effect, which increases the production cost of the attractant
