Problems solved by technology

[0003] However, there are deficiencies in the current fruit fly attractants: most of the fruit fly attractant formulations are liquid formulations, which are easily isomerized or oxidized under the influence of light and temperature conditions; The effect is generally only 2 to 4 weeks, and cannot maintain a stable release rate for a long time; the amount of attractant used is relatively large, and the operability is poor

Abstract

The invention discloses a slow-release attractant for fruit flies and a preparation method of same. The slow-release attractant consists of an attractant, a paraffin carrier and cellulose acetate fiber bundles, wherein the attractant and paraffin carrier are blended to fill the cellulose acetate fiber bundles. The preparation method is simple and low-cost and is high in operability; speed of oxidization and decomposition of active components in the attractant are reduced, and use amount of the attractant is greatly reduced too. The slow-release attractant can stably and continuously release the attractant for at least twelve weeks.

Description

technical field [0001] The invention belongs to the technical field of insect attractants. More specifically, it relates to a slow-release attractant for fruit flies and a preparation method thereof. Background technique [0002] Fruit flies are herbivorous insects, and their larvae are latent feeding. They are important and destructive agricultural pests in the world. They can seriously harm fruits and vegetables all over the world, restrict the export of local fruits and vegetables, and cause serious economic losses every year. At present, the use of attractants to trap males and population monitoring of fruit flies has become an effective technical means to control fruit fly pests. [0003] However, there are deficiencies in the current fruit fly attractants: most of the fruit fly attractant formulations are liquid formulations, which are easily isomerized or oxidized under the influence of light and temperature conditions; The effect is generally only 2 to 4 weeks, and...
