Description

Cherry fruit fly trapping device

Technical Field

The utility model relates to the technical field of plant protection, in particular to a cherry fly trapping device.

Background

Cherry drosophila is a kind of insect pest with important economic significance, and seriously damages cherry (European sweet cherry) and other soft-skin fruits with high added value, mainly comprises fruit flies with lepidoptera, gorgeous drosophila, sub-gorgeous drosophila and the like, and belongs to diptera, drosophila and Drosophila. When cherry fruit fly is harmful, female insects pierce the fruit skin by using a serrated oviposition device, spawn is laid in the fruit, and after hatching, the larvae feed on pulp, so that the fruit can not be eaten and lose commodity value, and direct economic loss is caused. Cherry fruit fly is multi-feeding, and besides cherry, host is harmful to more than 60 kinds of soft skin fruits such as blueberry, strawberry, raspberry, grape, fig, kiwi fruit, etc. When the climate condition is proper, cherry flies are bred for every two weeks for one generation, the single female spawning quantity reaches 400, the generation is short, the biological characteristics of strong fertility enable the population quantity of the cherry flies to be rapidly increased in a short period, serious harm is caused when fruits are about to mature, and the fruits fall down before maturity or are full of the fruits. In recent years, cherry flies have been reported to be harmful in multiple provinces such as Sichuan, shandong, guangxi, guizhou, henan, hubei and Yunnan, so that serious economic losses are caused in the soft skin fruit industry of places, for example, in the cherry producing area of Sichuan Abam, if the population of cherry flies is controlled in the early stage of cherry maturity without strict measures, the insect fruit rate in part of late-maturing cherry gardens can reach more than 90%.

Currently, cherry flies are controlled by chemical measures, and traps are generally only used for monitoring occurrence conditions. When the occurrence of cherry flies is monitored in an orchard, in order to prevent the cherry flies from propagating on the fruits in a large quantity, pesticide needs to be sprayed once every 5-7 days to kill the cherry flies in the orchard until the fruits are all harvested. The pesticide is used in the vicinity of the harvest period, which may cause the amount of pesticide residue in fruits to exceed the standard when the fruits are on the market, and the pesticide resistance of pests is easily generated by spraying the pesticide frequently, which is unfavorable for long-term control of cherry flies, so that development of new green control measures for controlling the number of cherry flies in the field is needed.

The pest trapping and controlling technology is used for controlling various lepidoptera, coleopteran and dipteran pests, and has better control effect. At present, the development of cherry fly attracting technology is still in a starting stage, most of the cherry fly traps put on the market are used in series, are not suitable for trapping cherry flies, and the traps designed for the cherry flies are also suitable for attracting indoor common black-belly flies and other species, and do not consider the unique biological and behavioral learning such as the visual preference, the olfactory preference and the like of field cherry flies, so that the trapping effect is not strong, and the control effect is poor.
