Abstract

The invention discloses an application of hansenula anomala in preparing citrus fruit fly bait. The invention also discloses citrus fruit fly bait which consists of hansenula anomala hydrolysis fermentation broth and auxiliary bait, wherein the auxiliary bait includes polypeptone, brown sugar, table vinegar or ammonium acetate, preservative and water composition or sweet and sour liquid. The citrus fruit fly bait disclosed by the invention realizes a good effect on inducing bactrocera minax and bactrocera dorsalis as well as a good effect on inducing both the females and males of the bactrocera minax and bactrocera dorsalis, is safe and non-toxic and harmless to human bodies and other beneficial insects, and avoids the residues.

Description

technical field [0001] The invention belongs to the field of citrus pest control, in particular to a Hansenula anomaly ( Hansenula anomala ) in the preparation of the citrus fruit fly attractant bait, the present invention also relates to the citrus fruit fly attractant bait. Background technique [0002] Bactrocera citrus Bactrocera ( Tetradacus ) minax , also known as Bactrocera citrus, belongs to Diptera, Tephritidae, Tephragidae, commonly known as "citrus maggot", is a destructive pest of citrus. There is one generation of Bactrocera citrus per year, and the damaged fruit is called maggot fruit or maggot orange. Bactrocera citrus overwinters in the soil as a pupa, and usually emerges from the soil in mid-to-late May. After the adults are sexually mature, they fly to the orange tree to mate and lay eggs. The female adults lay eggs on the inner cortex of the fruit. Generally, there are 13-17 eggs in each egg-laying hole, up to 35 eggs. The damaged fruit changes from h...
