Bactrocera dorsalis drug and preparation method thereof

Abstract

The invention relates to a bactrocera dorsalis drug and a preparation method thereof. The bactrocera dorsalis drug is prepared from the raw material components in percentage by mass: 5 percent to 10 percent of attractant, 0.5 percent to 1.0 percent of insecticidal composition, 2 percent to 5 percent of emulsifier, 2 percent to 5 percent of coemulsifier, 1 percent to 3 percent of solubilizer, and the balance of water. The preparation method comprises the steps of mixing the attractant, the insecticidal composition and the emulsifier according to the proportion, then adding one third of water under intense mixing, adding the coemulsifier after 10 minutes, continuously stirring for 20 minutes, adding the rest of water and solubilizer, and stirring for 30 minutes to obtain the bactrocera dorsalis drug. According to the bactrocera dorsalis drug and the preparation method thereof provided by the invention, the attractant and the insecticidal composition are emulsified and coated by the emulsifier so as to obtain a uniform solution drug, demulsification is continuously carried out along with the volatilization of water in the drug, and the attractant and the insecticidal composition are released; the technical principle is that through an emulsifying technology, the release speed of methyleugenol is retarded, and the time for attracting and killing the bactrocera dorsalis is prolonged.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a fruit fly medicament and a preparation method thereof. Background technique [0002] Fruit fly is an important pest of fruit trees. It has a very strong reproductive ability and is migratory. There is a tail needle at the tail of the fruit fly, that is, the ovipositor, and its eggs are produced in the peel of the fruit fly through the tail needle, and the egg mass is difficult to find with the naked eye. The adult moths lay eggs and penetrate into the fruit, and the hatched larvae eat the flesh of the melon, causing local yellowing of the melon and fruit, and then the whole melon and fruit rots and becomes smelly, causing a large number of fallen melons and fruits. Gum flow, abnormal subsidence, hard skin of melons and fruits, bitter taste of melons and fruits, seriously affecting the quality and output of melons and fruits, and endangering pears, peaches, or...

Problems solved by technology

Although methyl eugenol has a good attracting effect on fruit flies, because methyl eugenol is exposed to the air and is affected by oxygen, light, heat, etc., it is easy to deteriorate and fail. The control effect is not ideal
