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 objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail in conjunction with specific embodiments.

[0027] In recent years, with the strengthening of people's awareness of environmental protection and the requirements of sustainable development of agriculture, the research on the prevention and control technology of alfalfa bug has entered a new era. Using sex pheromone to trap and control male alfalfa bugs, on the one hand, directly reduces the damage of adults to crops, on the other hand, greatly reduces their mating rate and reduces the population of offspring, so as to achieve the goal of effective control of alfalfa bugs.

[0028] As an embodiment of the present invention, the alfalfa bug attractant is composed of the following components according to their respective weight percentages:

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

[0030] 4-carbonyl-trans-2-he...

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 insect sex pheromone preparation, in particular to a clover bug sex attractant and its use. Background technique [0002] Alfalfa mirids are arthropods of the Mirididae family. Mainly harm alfalfa, sweet clover, potato, cotton and other crops. The feeding habit of alfalfa mirid is very mixed, it is preferable to be a variety of plants, especially to eat Chenopodiaceae, legumes, cucurbitaceae, flax and other crops and pastures, such as beets, beans, melons, flax and alfalfa, etc., do not eat Gramineae. Nymphs or adults like to gather activities, generally more than a dozen or dozens of them gather on a plant and feed on young plant tissues, such as cotyledons, heart leaves, flower buds and floral organs of newly unearthed seedlings. The crawling ability of nymphs and adults fly Strong ability, rapid spread and migration, the peak of activity is in the morning and evening of each day, and the back of the plan...
