Volatile attractant applied to citrus fruit flies and application thereof

Abstract

The invention provides a volatile attractant applied to citrus fruit flies. The volatile attractant is prepared from the following components: ethyl propanoate, ethyl caprylate and Z,3-hexenyl acetateaccording to a mass ratio of (1-8) to (1-8) to (1-8). When the attractant is used, the attractant is added into a carrier or is placed in a monitoring, trapping and killing device used for attractingand killing the citrus fruit flies; the device comprises a main body, an upper insertion part and a lower insertion part; the attractant is placed in the main body; a contact insecticide is distributed on the outer surface of the main body. The attractant is composed of a series of volatile substances included in fruits, is easily available in raw materials, simple in formula and convenient to prepare, and can achieve an excellent effect of attracting mature citrus fruit flies and especially mature mated citrus fruit flies.

Description

technical field [0001] The invention relates to an attractant of the fruit fly genus, in particular to a volatile attractant of Bactrocera dorsalis. Background technique [0002] Bactrocera fruit flies are native to the tropical and temperate regions of Asia and Australia, and are the main fruit pests in these regions. Of these, Bactrocera dorsalis is the most destructive pest, attacking citrus, mango, peach, guava, carambola, and many other fruits. Bacteralis orange, which colonized sub-Saharan Africa and Hawaii, was introduced to tropical Queensland in 1995. [0003] The flying ability of Bactrocera dorsalis is very strong, and it is easily attracted by various volatile substances. Methyl eugenol is well known as an attractant for male fruit flies. Food attractants for immature female fruit flies include ammonia and various odors associated with fermentation, and volatile attractants have been successfully used to monitor B. dorsalis by trapping and to control B. dorsal...

AI Technical Summary

Problems solved by technology

After mating, mature Bactrocera dorsalis will lay eggs on many fruits, and the larvae will feed on the pulp after hatching from the eggs, resulting in a large number of rotten fruits and fruit drop, seriously affecting the quality and yield of fruits

[0004] At present, there is no particularly effective method for mature and mated female Bactrocera dorsalis. Studies have found that volatile substances in certain fruits are extremely attractive to Bactrocera dorsalis, so these volatile substances were used Food attractants made of substances are used to trap and kill Queensland fruit flies. For example, ethyl acetate, ethyl propionate and ethyl butyrate are mixed to make attractants. The effect is not ideal, and it is aimed at Queensland fruit flies. Not Bacteritis Bacteria
