Problems solved by technology
[0003] Among the existing control methods, the use of attractants to lure and kill, that is, the use of insect semiochemical substances for prevention and control is a commonly used green and pollution-free control method, but the existing attractants are mostly used for horizontal pit cutting. Pine beetle, Pine beetle, Huashan pine beetle, but little research has been done on the control of Pine beetle in Yunnan

Embodiment 1
[0021] As an embodiment of the present invention, the odor composition used to lure the Yunnan tip-cutting beetle consists of 4-allyl anisole, farnesene, α-pinene and longifolene, and every milliliter of the solution contains 0.5 mg of 4-allyl anisole, 1 mg of farnesene, 2 mg of α-pinene, and 2 mg of longifolene.
Embodiment 2
[0023] As an embodiment of the present invention, the odor composition used to lure the Yunnan tip-cutting beetle consists of 4-allyl anisole, farnesene, α-pinene and longifolene, and every milliliter of the solution contains 4-allyl anisole 1 mg, farnesene 0.5 mg, α-pinene 1 mg, longifolene 2 mg.
Embodiment 3
[0025] As an embodiment of the present invention, the odor composition used to lure the yunnanensis beetle consists of 4-allyl anisole and farnesene, containing 1 mg of 4-allyl anisole in every milliliter of solution , farnesene 0.5 mg.

The invention belongs to the field of insect control, and in particular relates to an odor composition used to lure Yunnan beetles, comprising at least two of 4-allyl anisole, farnesene, α-pinene or longifolene. The present invention utilizes chemical information substances containing hosts and worms to attract a large number of Yunnan tip-cutting beetles, make them gather in a certain device and then kill them. The advantages of pesticide resistance make the past passive chemical control into active biological control, and achieve the purpose of monitoring and forecasting forestry pests according to the number of bark beetle in the trap.
Description
technical field [0001] The invention belongs to the field of insect control, and in particular relates to an odor composition for attracting the tip-cutting beetle of Yunnan. Background technique [0002] Tomicus yunnanensis, which belongs to the family Scolytidae, belongs to the genus Tomicus and is a dry-boring pest that seriously damages Pinus plants. The tip-cutting beetle is distributed in Eurasian countries, and also occurs in many provinces of our country, among which Jilin, Shaanxi, Zhejiang, Sichuan, Chongqing and Yunnan are particularly serious. Morphologically, T. yunnanensis is very similar to Tomicus piniperda. For a long time, the tip-cutting beetle that endangers Yunnan pine has been considered as the vertical pit tip-cutting beetle. It was not until 2008 that it was confirmed morphologically that S. yunnanensis was a new species of S. yunnanensis that had not yet been described, and it was described and named as S. yunnanensis. The Yunnan pine beetle is ma...
