Fruit fly trapping and killing device

Abstract

The invention discloses a fruit fly trapping and killing device. The fruit fly trapping and killing device comprises a plurality of trapping and killing bottles and a supporting frame, and the multiple trapping bottles are hung at the top end of the supporting frame; each trapping and killing bottle comprises a bottom support, a lower bottle body, an upper bottle body and a bottle cap which are sequentially arranged from bottom to top; first necking cylinders extending upwards into inner cavities of the lower bottle bodies are arranged in the centers of the bottoms of the bottom supports; a flaring part is arranged at the top end of each first necking cylinder; a plurality of second necking cylinders is arranged at the top end of each flaring part; a supporting table is arranged in each upper bottle body; a trapping and killing bowl is arranged on each supporting table; and trapping and killing agents are arranged in the trapping and killing bowls. The first necking cylinders extendingupwards into the inner cavities of the lower bottle bodies is arranged in the centers of the bottoms of the bottom supports, the trapping and killing agents attract fruit flies to enter the lower bottle bodies along the first necking cylinders, trapping of the fruit flies is achieved, the lower bottle bodies, the upper bottle bodies and the bottle caps are sequentially fixed in a threaded mode and can be separated in pairs, discharging of the fruit flies and replacement of the trapping and killing agents are facilitated, the cost is low, environmental friendliness is achieved, and the trapping and killing effect is good.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit fly trapping and killing, in particular to the technical field of a fruit fly trapping and killing device. 【Background technique】 [0002] Small berries represented by blueberries, raspberries and grapes, and cherries are called "third-generation fruits" or "golden fruits" in the international market and are very popular among people. In recent years, with the large-scale planting of such soft-skinned fruits at home and abroad, large-scale fruit fly infestations have also occurred in various places. Drosophila females lay eggs on soft-skinned fruits, and after hatching into larvae, they feed on the pulp and cause the fruit to rot. At the same time, they also cause secondary infection of pathogenic microorganisms, eventually causing extensive damage to the orchard. [0003] The traditional pesticide spraying method has no significant effect on the control of fruit flies, it is difficult to kill th...

Drosophila females lay eggs on the soft-skinned fruit, hatch into larvae and feed on the pulp, causing the fruit to rot, and also causing secondary infection of pathogenic microorganisms, eventually causing extensive damage to the orchard

[0003] The traditional pesticide spraying method has no significant effect on the control of fruit flies, it is difficult to kill the adult fruit flies flying all over the sky, and it will seriously pollute the fruit, which is not in line with the development concept of green and organic agriculture today

At present, fruit farmers in the field often use plastic buckets or plastic bottles as traps. This kind of device is low in cost, convenient and practical, but because it has no cover and is not resistant to rain, the trap is prone to failure, and the fruit flies are easy to escape.
