Granular holotrichia parallela slow-releasing sex attractant and preparation method thereof

Abstract

The invention relates to a slow-releasing sex attractant and a preparation method thereof and particularly relates to a granular holotrichia parallela slow-releasing sex attractant and a preparation method thereof. The granular holotrichia parallela slow-releasing sex attractant is prepared from sex attractant effective components, a slow-releasing carrier, a diluting agent, an auxiliary agent and a wetting agent according to a certain ratio, wherein the sex attractant effective components comprise methyl L-isoleucinate and (R)-(-)-linalool; the slow-releasing carrier is medical starch. Compared with an existing holotrichia parallela sex attractant, the granular holotrichia parallela slow-releasing sex attractant has the advantages of being simple in preparation process, reliable in dosage preservation, obvious in releasing rule and the like, and is absolutely environmentally-friendly; a releasing curve of a slow-releasing preparation meets a quadratic trinomial rule; the attraction acting effect on holotrichia parallela can last for 15-20 days and the disadvantages that the lasting period is short and the labor cost is wasted in an existing preparation are overcome; the frequent raining characteristic in a rain spell is avoided; the granular holotrichia parallela slow-releasing sex attractant has the feasibility of large-scale production, is good for large-scale popularization and has the economic significance and the ecological significance.

Description

technical field [0001] The invention relates to a slow-release attractant and a preparation method thereof, in particular to a granular black-branched beetle slow-release attractant and a preparation method thereof. Background technique [0002] The black beetle is one of the most harmful pests in various crops such as peanuts, soybeans, sweet potatoes, and corn. It often causes large-scale crop failure of peanuts, so it has always been the focus and difficulty of pest control work. In recent years, with the development of my country's agricultural production, the area of ​​insect damage has increased rapidly, especially in peanut fields, where the number of insects per hectare is as high as hundreds of thousands or even millions. According to the five-year follow-up survey, the annual peanut production loss caused by the diablo beetle is more than 150 million kilograms. [0003] At present, there are mainly chemical methods for the prevention and control of black beetles: u...

Problems solved by technology

The currently used lure wick (ZL201120387584.4) is to use the active ingredients of its sex attractant to adsorb on absorbent cotton, hang it in the field, and trap male adults who come to mate. This method is efficient and targeted. , but the dosage form has a very fast volatilization rate and uneven release, so it is necessary to replace the lure in the field every day, and during the mating period of the black beetle adults, there is a lot of rain, not only the medicine is easily eroded by wind and rain, but also increases the labor of farmers. This restricts the further promotion of the technology
