Abstract

The invention discloses a bactrocera dorsalis attractant. The formula of the attractant is hydrolysate obtained through enzyme hydrolysis of soybean protein and protein of brewer yeast at a certain ratio under a certain condition. The attractant is beneficial to environmental protection and the edible safety of fruits, the ecological environment is not polluted, and the human health and the safety of natural enemies of bactrocera dorsalis are not threatened. The attractant is simple in preparation method and low in production cost, and the condition that relatively high attractive force can be stably kept by the hydrolysate can be ensured. The attractant has relatively good attracting action on male and female worms of the bactrocera dorsalis, so that the targets of controlling the population quantity of the bactrocera dorsalis and reducing the hazard ratio can be achieved, and the bactrocera dorsalis attractant has good popularization significance.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to an attractant for Bactrocera dorsalis. Background technique [0002] Bactrocera dorsalis (Hendel) belongs to Diptera (Diptera), Tephritidae (Tephritidae), and is a worldwide quarantine pest. It has a wide range of memory and strong reproductive ability, and can harm 46 families such as guava and mango. More than 250 kinds of fruits and vegetables, vegetables and flowers are destructive pests, which have caused serious economic losses to the fruit, vegetable and flower industries in many countries. [0003] At present, the following methods are mainly used for the detection and control of Bactrocera dorsalis at home and abroad: [0004] (1) Chemically synthesized attractant: At present, it has been found that various chemical substances such as methyl eugenol, decoy ketone, and methoxybutyrophenone have a certain attractant effect on Bactrocera dorsalis, among wh...
