Citrus fruit fly attractant and preparation method thereof

Abstract

The invention discloses a citrus fruit fly attractant and a preparation method thereof, and belongs to the field of preventing plant diseases and insect pests. The attractant comprises the following components in parts by weight: 150-400 parts of eugenol methyl ether, 3-5 parts of ethyl butyrate, 10-12 parts of geraniol, and 6-10 parts of linalool, and further comprises 2-8 parts of 2,6-butylated hydroxytoluene. The preparation technology comprises the following steps: weighing and taking the eugenol methyl ether, the ethyl butyrate, the geraniol and the linalool in parts by weight, pouring the eugenol methyl ether, the ethyl butyrate, the geraniol and the linalool which are weighed and taken into a beaker, adding water into the beaker, and fully stirring the mixture of the eugenol methyl ether, the ethyl butyrate, the geraniol, the linalool and the water so as to obtain a fragrance source agent of which the concentration is 10<-3>g / mL-10<-1>g / mL; weighing and taking the 2,6-butylated hydroxytoluene in parts by weight, pouring the weighed and taken 2,6-butylated hydroxytoluene into the beaker, adding the water into the beaker, and fully stirring the mixture of the 2,6-butylated hydroxytoluene and the water so as to obtain an oxidizing agent solution of which the concentration is 10<-3>g / mL-10<-1>g / mL; respectively putting the obtained fragrance source agent and the obtained oxidizing agent solution into a freezing chamber to perform the preservation, wherein the refrigerating temperature is 4-8 DEG C; during use, uniformly mixing the fragrance source agent and the oxidizing agent solution according to the compounding ratio of 10:1 so as to obtain the citrus fruit fly attractant of which the concentration is 10<-3>g / mL-10<-1>g / mL. According to the method, not only the production is simple, but also the cost is low, and products have the characteristic that the attractive effect is strong.

Description

technical field [0001] The invention relates to the field of pest control, in particular to an attractant for Bactrocera dorsalis and a preparation method thereof. Background technique [0002] Bactroceradorsalis (Bactroceradorsalis Hendel), also known as Bactroceradorsalis citrus, Bactrocera orientalis, Bactrocera dorsalis, etc., is one of the important pests of agriculture, especially fruit. The host range of Bactrocera dorsalis is very wide, and it mainly harms more than 250 kinds of crop fruits in 46 families such as mango, citrus, carambola, papaya and so on. [0003] In the monitoring and control of Bactrocera dorsalis, it is better to use eugenol methyl ether sex attractant to attract male adults of Bactrocera dorsalis, but due to the difference in the additives of the attractant, the attractant of Bactrocera dorsalis produced by different units is less effective. Insect effects vary. Contents of the invention [0004] The object of the present invention is to pro...
