Abstract

The present invention relates to a new type of tropism agent for cotton bollworm. The tropic agent is any one of two substances, trans-9-hexadecenal and cis-11-hexadecenyl acetate, or a binary composition thereof, and its tropic effect is better than that of the same dosage. The cotton bollworm pheromone phalanx. Among them, the effect of fascination is the best when the ratio of binary composition is 1:1. When applied in the field, 20-40 oblique silks are installed per mu, and 10-200mg of oblique agent is added to each oblique silk, and the oblique rate of more than 90% can be achieved. The invention is safe to the environment and natural enemies, convenient to operate, low in cost, easy to produce, used for controlling cotton bollworm and armyworm in a large area, and has remarkable ecological and social benefits.
