Problems solved by technology

[0003] In 1993, the potato beetle was introduced from Kazakhstan into the northern part of the Xinjiang Autonomous Region of my country, and spread eastward year by year. By 2010, the potato beetle had spread to most areas north of the Tianshan Mountains. The beetle-infested area borders Russia, and there are sporadic reports of the interception and occurrence of potato beetles, but there is no document yet documenting the large-scale occurrence of the beetle

Embodiment 1

[0041] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art, and the raw materials used are all commercially available products. The screening of embodiment 1 potato beetle repellent

[0042] 1. Materials and methods

[0043] 1.1 Source of tested insects

[0044] The source of the tested insects was collected from the potato experimental field of Xinjiang Academy of Agricultural Sciences Comprehensive Experimental Field (N43°57'8.80",; E87°29'32.18"), a special breeding ground for potato beetles. No.), this variety was bred by the Potato Research Institute of Heilongjiang Academy of Agricultural Sciences, with a full growth period of 140 days and an adult plant height of about 65cm. The potato beetle migrated naturally from adjacent farmlands, and no pesticides wer...

Embodiment 2

[0103] The impact of embodiment 2 compound concentration and compound mode on repellent effect

[0104] 1. Materials and methods

[0105] 1.1 Source of tested insects

[0106] During the previous experiment, due to the natural death and growth characteristics of some insects that did not meet the requirements of the experiment, the insect source has been in a state of continuous replenishment, and the required insect source was collected in the experimental field regularly (about two weeks). Due to the late potato beetle The reason for the development of potato beetles in the field is that it is difficult to directly collect larvae that meet the standards, and some larvae are adults of the right age when collected. Ensure the consistency of insect source health and physiological standards (body weight) during the test to reduce accidental errors.

Abstract

The invention provides a potato beetle repellant and application thereof. The repellent is at least one selected from bornyl acetate, α,β-thujone, dihydrocarvone, and eucalyptol. The present invention provides four kinds of active repellents to potato beetles, the repellent effect is directly proportional to the concentration of the reagents, by mixing and compounding two or more reagents (especially bornyl acetate: α, β-side Thujone: Eucalyptol = 1:1:1, Bornyl Acetate: α,β-thujone = 1:1), the insect repellent effect can be improved. The invention provides a powerful tool for the control of the potato beetle.

Description

technical field [0001] The invention relates to the field of agricultural pest control, in particular to a potato beetle repellent and application thereof. Background technique [0002] Potato beetle (Leptinotarsadecemlineata (Say)) belongs to Coleoptera (Coleoptera), Chrysomelidae (Chrysomelidae) LeptinotarsaStal, is a kind of leaf-eating pests that are destructive to potato production. Both larvae and adults feed on crop leaves. (Solanaceae crops such as potatoes) as food, the larvae eat about 40cm of potato leaves every day 2 , adult food intake reduced by about 10cm per day 2 . Once the insect situation occurs in the field, it will cause 30% to 50% yield loss, and it can reach 90% when the insect infestation is serious (potato beetle identification and its distribution, spread and harm in Xinjiang); potato beetle has a very strong ability to expand, It is native to Mexico and the southeastern United States. It was discovered and named in the early 19th century. It ini...
