Attractant for oriental tobacco budworms

Abstract

The invention belongs to the technical field of development of pest attractants and particularly relates to an attractant for oriental tobacco budworms. The attractant for oriental tobacco budworms isprepared from four or more of cis-3-hexylene-1-alcohol, trans-2-hexylene-1-alcohol, 1-hexanol, nonanal, trans-beta-caryophyllene, cis-3-hexene acetate, and cis-3-hexenylhexyl ester as attractant components. Compared with a single attractant component, the attractant for oriental tobacco budworms, provided by the invention, combines multiple different attractant components so as to obviously enhance the attractant effect; and tests show that trans-beta-caryophyllene-3-hexylene-1-alcohol has an enhanced attractant effect on the composition of cis--hexylene-1-alcohol, trans-2-hexylene-1-alcohol,1-hexanol and nonanal.

Description

technical field [0001] The invention belongs to the technical field of pest attractant development, in particular to a tobacco budworm attractant. Background technique [0002] Tobacco budworm is a Lepidoptera pest with wide distribution, miscellaneous feeding habits, strong fecundity, and strong stress resistance. It mainly damages crops such as tobacco. Tobacco budworm feeds on the heart buds and young leaves of tobacco, and in serious cases eats up the mesophyll; or drills into the tender stems to feed, causing the young leaves on the upper part of the stem to wither and die, seriously affecting the yield and quality of tobacco. For a long time, people have used chemical pesticides to prevent and control budworms. Although chemical pesticides have good effects and quick results, there are generally "3R" problems. Increasing year by year, environmental pollution is becoming more and more serious, and the amount of pesticide residues in tobacco leaves is increasing. [00...
