Problems solved by technology

Chemical control has the characteristics of obvious effects and quick results. However, the long-term use of these chemical pesticides will inevitably lead to the resistance of Lygus clover bugs, forcing farmers to continuously increase the amount of pesticides used to control pests, resulting in a vicious cycle of drug resistance and increased dosage. very serious

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

[0027] In recent years, with the strengthening of people's awareness of environmental protection and the requirements of sustainable agricultural development, the research on the control technology of Lygus sativa has entered a new period. The use of sex pheromones to trap and control male Lygus sativa can directly reduce the damage of adults to crops, and greatly reduce their mating rate and the number of offspring populations, so as to achieve the goal of effectively controlling Lygus sativa.

[0028] As an embodiment of the present invention, the sex attractant of Lygus californica consists of the following components according to their respective weight percentages:

[0029] Butyrate-trans-2-hexenyl 50-80%,

[0030] 4-Carbonyl-trans-2-hexenal 20-50%,

[0031] And th...

Abstract

The invention discloses a sex attractant for alfalfa plant bugs and application of the sex attractant. The sex attractant for the alfalfa plant bugs comprises the following components in percentage by weight: 50-80 percent of butyric acid-trans-2-hexene ester and 20-50 percent of 4-carbonyl-trans-2-hexenal, and the sum of weight percentage of the two components is 100 percent. The sex attractant for the alfalfa plant bugs is uniformly mixed with an organic solvent difficult to volatilize; then the mixed solution is put into a sealed plastic bottle; the plastic bottle is fixed on a sticky coloured card trap for trapping male alfalfa plant bug adults. The sex attractant for the alfalfa plant bugs, which is provided by the invention, can be accurately used for observing and predicting insect pest situations of the alfalfa plant bugs, trapping a large number of the alfalfa plant bugs, and disturbing the mating of the alfalfa plant bugs and has significance in comprehensive treatment of the alfalfa plant bugs.

Description

technical field [0001] The invention relates to the technical field of preparation of insect sex pheromones, in particular to a sex attractant for Lygus californica and its application. Background technique [0002] Lygus sativa is an arthropod of the Miridae family. It mainly harms alfalfa, sweet-scented clover, potato, cotton and other crops. The feeding habits of Lygus sativa are very mixed, and it is preferable to eat a variety of plants. It especially likes to eat crops and pastures such as Chenopodiaceae, legumes, cucurbitaceae, and flax, such as sugar beets, beans, melons, flax, and alfalfa. Poaceae. Nymphs or adults like to gather and move. Generally, a dozen or dozens of them gather on a plant to feed. They like to eat young plant tissues, such as cotyledons, heart leaves, flower buds, and flower organs of newly unearthed seedlings. Nymphs can crawl and adults can fly. The ability is strong, and the speed of diffusion and migration is fast. The peak of activity i...
