Abstract

The invention discloses a composite attractant of bactrocera dorsalis hendel, which comprises aqueous solution of a molasses, aqueous solution of a complex protein hydrolyzate and a fruit flavor. The mass ratio of the aqueous solution of the molasses to the aqueous solution of the complex protein hydrolyzate is 4:1; the complex protein hydrolyzate is the hydrolysate which is obtained by mixing soy protein and brewer's yeast protein at the weight ratio of 1:1-9, adding 5,000U / g of acidic protease, 0.5-5.0 parts by weight of preservative and 0.01-0.1 part by weight of spinosad, and hydrolyzing at 50 DEG C for 2hours. The formula of the composite attractant of the bactrocera dorsalis hendel is simple, and the raw materials are cheap and easy to obtain. The composite attractant has good effect of attracting the male and female adult bactrocera dorsalis hendel, and particularly, the composite attractant can attract more than 25% of bactrocera dorsalis hendel of 10-11 days old. The raw materials used for preparing the composite attractant do not contain any harmful chemical substances, have no toxic effects on people and animals and meet the environmental protection requirements.

Description

technical field

[0001] The invention relates to the field of plant protection, in particular to a composite attractant for Bactrocera dorsalis. Background technique

[0002] Bactrocera dorsalis ( Bactrocera dorsalis Hendel), belonging to Diptera (Diptera), is a major fruit and vegetable pest in tropical and subtropical regions, and is very dangerous. Its host range is very wide, and it mainly harms more than 250 kinds of crop fruits in 46 families such as mango, citrus, carambola, papaya, etc., mainly tropical and subtropical fruit and vegetable plants. Bactrocera dorsalis occurs throughout the year in southern my country, with serious generation overlap. In Guangdong, there are two hazard peaks each year. The occurrence of adults gradually increases from May, and a larger peak occurs in August, followed by another occurrence in November. 1 peak, and the occurrence of adults did not decrease slightly until December. Bactrocera dorsalis adults live up to 1 year and can sur...
