Embodiment 1

[0018] The preparation method of Taiwan rice borer attractant 1 comprises the following steps:

[0019] 1) Weighing cis-11-hexadecenal, cis-13-octadecenal and cis-9-hexadecenal in a weight ratio of 48:6:5, and mixing them uniformly to obtain an attractant for the stem borer;

[0020] 2) Weighing 50% of methyl salicylate and 50% of Chilo borer attractant by weight percentage;

[0021] 3) Mix the methyl salicylate and the attractant for the rice borer evenly to obtain the attractant 1 for the rice borer in Taiwan.

Embodiment 2

[0023] The preparation method of Taiwan rice borer attractant 2 comprises the following steps:

[0024] 1) Weighing cis-11-hexadecenal, cis-13-octadecenal and cis-9-hexadecenal in a weight ratio of 48:4:3, and mixing them uniformly to obtain an attractant for the stem borer;

[0025] 2) Weighing 1% of methyl salicylate and 99% of Chilo borer attractant by weight percentage;

[0026] 3) Mix the methyl salicylate and the attractant for the rice borer evenly to obtain the attractant 2 for the rice borer.

Embodiment 3

[0028] The preparation method of Taiwan rice borer attractant 3 comprises the following steps:

[0029] 1) Weighing cis-11-hexadecenal, cis-13-octadecenal and cis-9-hexadecenal in a weight ratio of 48:5:4, and mixing them uniformly to obtain an attractant for the stem borer;

[0030] 2) Weighing 30% of methyl salicylate and 70% of Chilo borer attractant by weight percentage;

[0031] 3) Mix the methyl salicylate and the attractant for the rice borer evenly to obtain the attractant 3 for the rice borer in Taiwan.

Abstract

The invention discloses a chilotraea auricilia dudgeon attractant, as well as a preparation method and application thereof. The attractant is prepared from the following raw materials in percentage by weight: 1-50 percent of methyl salicylate and 50-99 percent of chilo suppressalis attractant, wherein the chilo suppressalis attractant is two or three components of cis-11-hexadecenal, cis-13-octadecene and cis-9-hexadecenal; and the methyl salicylate and the chilo suppressalis attractant are uniformly mixed to obtain the chilotraea auricilia dudgeon attractant. The attractant is added into a lure, and then the lure is fixed in a boat-shaped trap for trapping chilotraea auricilia dudgeon. The insect pheromone can be used for effectively trapping chilo suppressalis, controlling population growth and reducing population quantity by utilizing combination of the chilo suppressalis attractant and methyl salicylate, can be used for trapping imagoes of chilotraea auricilia dudgeon and reducing the population density of chilotraea auricilia dudgeon, and has an important meaning to comprehensive treatment of chilotraea auricilia dudgeon.

Description

technical field [0001] The invention relates to the technical field of insect biological control, in particular to a Taiwan rice borer attractant and its preparation method and application. Background technique [0002] Taiwan rice borer (Chilo auricilius) belongs to Lepidoptera Pyralidae, a kind of borer pest, mainly damages grass crops such as rice, wild rice stem, corn and sugarcane, and can cause dead heart, white ears and Symptoms such as insect damage to plants affect the yield and quality of crops. Taiwan rice borer has the characteristics of miscellaneous food habits, many overwintering places, and damage caused by transplantation. It is one of the rice pests in my country, and the damage is increasing year by year. [0003] Our country adheres to the principle of "prevention first and combination of prevention and control". Chemical drug control has the advantages of quick effect and thorough insecticide, which is one of the most direct and effective methods of con...
