Problems solved by technology

The distribution of the rice stem borer in China is almost all over the rice area. The damage of the rice stem borer is mainly caused by the dry sheath, dry booting ear, white ear and insect damage to the plant, which greatly reduces the rice yield.
The control of C. borer usually uses chemical pesticides, but over time, C. borer inevitably develops resistance to various pesticides to varying degrees.
However, a large number of field experiments and applications have found that the lure effect of this ratio is not ideal, especially when the population density in the field is low, it is difficult to trap male moths

Abstract

The invention provides a sexual attractant and attraction core for attracting chilo suppressalis (Walker), and relates to the technical field of insect sexual attractants. The sexual attractant is prepared from active ingredients including, by weight, 50 parts of cis-11-hexadecenal, 4-10 parts of cis-13-octadecenal, 4-10 parts of cis-9-hexadecenal and 0.4-200 parts of cis-9-hexadecenol. The sexualattractant has a strong attraction effect on chilo suppressalis (Walker), is safe to human and animals, has no pollution to the environment and can reduce the use of pesticide. The sexual attractantis low in use cost and convenient to operate, can be applied to prediction and prevention of chilo suppressalis (Walker), and has good social, economic and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of insect sex attractants, and in particular relates to a sex attractant and a lure core for attracting Chilo suppressalis. Background technique [0002] Chilo suppressalis (Walker), belonging to Insecta, Lepidoptera, Mothidae, is widely distributed in temperate, subtropical and tropical regions, and is a worldwide rice pest. The distribution of the rice stem borer is almost all over the rice area in China. The damage of the rice stem borer is mainly caused by dry sheaths, dry boots, white ears and insect damage to the plants, which greatly reduces the rice yield. The control of Chilo borer usually uses chemical pesticides, but over time, Chilo borer will inevitably develop resistance to various pesticides to varying degrees. Many rice-growing regions have developed severe resistance to conventionally used insecticides, and with the rise of global temperatures, changes in field farming systems and the emerg...
