Technical Field

The invention belongs to the technical field of agricultural pest monitoring and trapping, and particularly relates to a lygus lucorum attractant and a using method thereof.

Background

In recent years, due to the large-area popularization and planting of transgenic insect-resistant cotton, the use amount of insect-resistant cotton field pesticides is greatly reduced, so that plant bug pests such as lygus lucorum (Apolygus lucorum) and Adelphocoris suturalis (Adelphoris suturalis) gradually become main pests of cotton fields. The lygus plants prick and absorb the juice of the cotton plants by the nymphs, so that the phenomena of massive drop of the bolls, head breaking of the cotton and the like are caused, more than 25 percent of economic loss can be caused when the harm is serious, and the problem of influencing the cotton production is already a prominent problem. Meanwhile, the lygus bugs have complicated hosts and can harm various crops such as jujubes, peaches, cherries, grapes and the like, and corresponding economic loss is brought. Therefore, a green and safe control means for controlling lygus lucorum is urgently needed.

Disclosure of Invention

The invention provides a lygus lucorum attractant and a using method thereof, aiming at the technical problem that green and safe lygus lucorum control means are urgently needed when lygus lucorum pests become main pests of crops such as cotton fields and the like, compared with the traditional chemical pesticide, the lygus lucorum attractant attracts insects to control pests by utilizing the attractant, and has the advantages of strong pertinence, considerable control effect, small environmental pollution and the like.

The lygus attractant provided by the invention comprises methyl levulinate and/or diethyl phthalate.

In one embodiment, the lygus attractant comprises methyl levulinate and diethyl phthalate, and the volume ratio of the methyl levulinate to the diethyl phthalate in the lygus attractant is (3:7) - (3: 1).

In one embodiment, the ratio of methyl levulinate to diethyl phthalate in the lygus attractant is (3:7) - (3: 2).

In one embodiment, the ratio of the methyl levulinate to the diethyl phthalate in the lygus attractant is (3:7) - (9:11), or the ratio of the methyl levulinate to the diethyl phthalate is (3:2) - (3: 1).

In one embodiment, the ratio of the methyl levulinate to the diethyl phthalate in the lygus attractant is (3:7) - (2:3), or the ratio of the methyl levulinate to the diethyl phthalate is (3:2) - (7: 3).

In one embodiment thereof, the ratio of methyl levulinate to diethyl phthalate in the lygus attractant is 3:7 or 3:2 by volume.

In one embodiment thereof, the lygus attractant is for attracting lygus lucorum and lygus lucorum.

In one embodiment thereof, the lygus attractant is used to lure adults of lygus bugs.

The invention also provides a using method of the lygus lucorum attractant, and the lygus lucorum attractant is used as a lure and placed in an insect trap.

According to the lygus attractant and the using method thereof, methyl levulinate and/or diethyl phthalate are/is used as functional components of the attractant, and pest control is performed by utilizing the attraction effect of the attractant on lygus pests, so that the attractant is strong in pertinence, good in control effect, small in environmental pollution, extremely low in toxicity of the methyl levulinate and the diethyl phthalate, small in toxicity to human beings and animals, and safe and reliable to use.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

The invention provides a lygus attractant which comprises methyl levulinate and/or diethyl phthalate. The lygus lucorum attractant adopts methyl levulinate and/or diethyl phthalate as functional components, has simple preparation method and lower cost, utilizes the attraction effect of the lygus lucorum attractant on lygus pests to prevent and control the pests, becomes an important component in a comprehensive pest prevention and control technical system, has the characteristics of strong pertinence, good prevention and control effect, small environmental pollution and the like, and can be used for monitoring and preventing and controlling cotton lygus lucorum; and the methyl levulinate and the diethyl phthalate have extremely low toxicity, are harmless to people and livestock, are environment-friendly, are not easy to generate drug resistance, and are safer and more reliable to use.

The embodiment of the invention carries out experimental verification on the using effect of the lygus lucorum attractant through a Y-shaped insect olfactory selector. The selectivity of the lygus lucorum and the lygus lucorum to cotton leaves, methyl levulinate, diethyl phthalate and the compound preparation of the methyl levulinate and the diethyl phthalate are compared, and experiments prove that the functional components of the lygus lucorum attractant, namely the methyl levulinate, the diethyl phthalate and the compound preparation of the methyl levulinate and the diethyl phthalate have good trapping activity to the lygus lucorum and the lygus lucorum, so that the lygus lucorum attractant has a good effect of trapping the lygus lucorum.

The experimental reagents and instruments used in the invention are as follows:

experimental reagent: methyl levulinate was purchased from Shanghai Crystal Biochemical technology Ltd, and diethyl phthalate was purchased from Shanghai Merlin Biochemical technology Ltd.

An experimental instrument: the Y-shaped insect olfactory selector is purchased from Shanghai Yuming instrument Co., Ltd, the glass rotor flowmeter is purchased from the auspicious cloud flow instrument factory, and the single-stage rotary-vane vacuum pump is purchased from the ruby vacuum equipment factory in Wenling City of Zhejiang province.
