Fruit fly trapping agent, preparation method and application thereof

Abstract

The invention discloses a fruit fly trapping agent, as well as a preparation method and application thereof. The fruit fly trapping agent comprises a trapping agent A and a trapping agent B. Calculated according to volume fraction, the trapping agent A comprises dimehypo, brown sugar, vinegar, wine and water, and the trapping agent B is methyleugenol, wherein the mass percent of acetic acid in the vinegar is larger than 0.6%; the mass percent of alcohol in the wine is larger than 52%. According to the fruit fly trapping agent, smell diffused by the sugar and vinegar trapping agent and the methyleugenol is completely utilized to induce a fruit fly to enter a trapping bottle, and the fruit fly is killed by utilizing the dimehypo to achieve the effect of trapping and killing the fruit fly in the field. The trapping bottles are hanged at the periphery of an orchard, and therefore, an external insect source likely to invade the orchard can be prevented, and the control effect is strengthened. By utilizing the fruit fly trapping agent, male and female worms of the fruit flies can be trapped simultaneously, and the defect of only trapping the male worms of the fruit flies or the female worms of the fruit flies by other fruit fly trapping agents is overcome. In addition, because the dimehypo does not have pesticide smell, the trapping effect of the trapping agent is not affected.

Description

Technical field [0001] The invention relates to the field of agricultural science, in particular to a fruit fly trapping agent and its preparation method and application. Background technique [0002] Fruit fly is an important pest of fruit trees. It has very strong reproductive ability and migratory nature. Because its eggs are laid in the peel of hanging melon through tail needles, it is difficult to find the egg mass. The fruit fly has a tail needle, which is the ovipositor. The adults lay eggs and pierce the melons and fruits. The hatched larvae eat the flesh of the melons, causing local yellowing of the melons, and then the whole melons (fruits) rot and become smelly, causing a large number of melons (fruits) to fall. Condensation of glue in the wound, deformed sinking, hard skin of melon (fruit), bitter taste of melon (fruit), which seriously affects the quality and yield of melon (fruit), and harms pears, peaches, oranges, guava, mango, carambola, A variety of economic f...

AI Technical Summary

Problems solved by technology

Extensive use of pesticides to control this kind of pests will lead to serious problems such as pest resistance and pesticide residues, so it is difficult to achieve the desired effect by chemical control

But the investment of fruit bagging is big and labor-intensive and time-consuming

The fruit fly traps currently used are mainly sex lures, which can only trap fruit fly males or females usually, and the trapping and control effect is not ideal.
