Problems solved by technology

[0005] The purpose of the present invention is to overcome the phenomenon that the botanical attractant cannot completely trap the adults when the trap lures and catches the adults of the red beetle, and some of the adults are transferred to the surrounding pine trees, which aggravates the damage of the pine trees around the trap , and provide a kind of attractant that is used to lure red fat beetle, this attractant has added the verbenone synergist of low dose in the plant source attractant, can make the original plant source attractant to the size of red fat beetle The trapping effect of beetles increases by 42-46%. The synergist is a natural organic substance with stable structure and stable chemical properties under normal temperature and pressure. It is non-toxic and does not pollute the environment; it is simple to prepare, easy to use, and slow to release. Long service life

[0019] The proportioning dosage listed in Table 1 is loaded into the release carrier.

[0020] Put the release carriers with different synergist contents next to the release carrier of the botanical attractant of the red beetle, check the number of insects in the traps of each synergist and the control, the average number of lures = the total number of traps in the trap Number of bugs / number of traps. 10 repetitions were set for each carrier, and the insect-attracting effect of the measured release carrier is listed in Table 1

Abstract

The present invention relates to an attractant for attracting dendroctonus valens leconte. Said attractant includes component A, component B, component C and component D, in which the component A is alpha-pinene, component B is beta-pinene, component C is 3-carene and component D is verbenone. Their weight mixing ratio is 1:2:10:0.0011.

Description

technical field [0001] The invention relates to an attractant, in particular to an attractant for attracting the red beetle beetle. Background technique [0002] The red beetle Dendroctonus Valens LeConte is a major invasive pest that harms Pinus tabulaeformis, Pinus tabulaeformis, Pinus huashanensis, Pinus sylvestris and other Pinaceae plants. The worm is native to North America, and according to research, it invaded my country with the timber trade in the 1980s. The red beetle began to appear in Qinshui, Yangcheng and other places in Shanxi Province in the autumn of 1998. After that, it broke out in large areas from south to north in the concentrated distribution of Chinese pine forests in Shanxi Province. According to the survey in 2000, the occurrence area of ​​the red beetle in Shanxi Province was 3.85 million mu, involving 47 counties in 8 cities of the province and 74 state-owned forest farms in 7 provincial forestry bureaus, and the disaster area was 1.93 million mu...
