Gel-like holotrichia parallela sex attractant slow release dosage form as well as preparation method and application thereof

Abstract

The invention relates to a gel-like holotrichia parallela sex attractant slow release dosage form. The gel-like holotrichia parallela sex attractant slow release dosage form is mainly prepared from the following raw materials: a sex attractant effective ingredient, a slow release gel carrier and a solvent, wherein a mass ratio of the sex attractant effective ingredient to solid content of the slow release gel carrier is 1:(0.2-0.6); a massic volume ratio of the solid content of the slow release gel carrier to the solvent is 1:(5-20); the sex attractant effective ingredient is methyl L-isoleucinate and (R)-(-)-linalool in a mass ratio of (5-7):1; the slow release gel carrier is hydroxypropyl methylcellulose and hydroxypropyl methylcellulose phthalate in a mass ratio of 1:(0.1-0.4); and the solvent is ethanol and deionized water in a volume ratio of 1:(10-20). The slow release dosage form provided by the invention has lasting period as long as 60 days, is simple in preparation technology, obvious in release rules, green and environment-friendly, has the characteristic that the whole adult active stage of holotrichia parallela can be covered after the dosage form is thrown for one time, is beneficial to large-area popularization and has obvious economic benefit and ecological significance.

Description

technical field [0001] The invention relates to a slow-release dosage form of a sex attractant and its preparation method and application, in particular to a gel-like slow-release sex attractant for black beetles and its preparation method and application. Background technique [0002] The black gill beetle is a widely distributed agricultural and forestry pest, and its harmfulness ranks first among all kinds of beetles. There is one generation of beetles a year, and the adults are of summer occurrence type. Generally, the emergence of adults begins in the first and middle ten days of June and ends in the middle and late August. Adults feed on the leaves of elm, poplar, willow, pagoda tree and other trees, and have the characteristics of gluttony. Larvae mainly feed on the underground parts of various crops such as peanuts, soybeans, potatoes, and wheat, which often cause large-scale production reduction or even failure of crops, so they have always been the focus of pest c...

Problems solved by technology

However, the main active period of the adult beetles is more than two months, and there is no high-efficiency slow-release dosage form that can basically cover the entire active period of the adult beetles with one use.
