Automatic-liquid-supplementing fruit fly trap

Abstract

The invention discloses an automatic-liquid-supplementing fruit fly trap which comprises a trapping agent container comprising a main container and a supplemented liquid container. A window for fruitflies to fly in is arranged on the upper portion of the main container, an automatic liquid supplementing device is arranged at the bottom of the main container and comprises a shell fixed at the bottom of the main container, the shell comprises an upper cavity and a lower cavity, a liquid incoming joint is arranged on the side face of the lower cavity, the upper cavity and the lower cavity are communicated through a vertical tube hole, a liquid discharging hole is formed in the upper cavity, a buoyancy block capable of moving up and down is arranged in the upper cavity, a pull rod matched with the vertical tube hole is connected on the buoyancy block, and an end cap is arranged at the lower end of the pull rod; a liquid discharging tube connected with the liquid incoming joint is arrangedon the lower portion of the supplemented liquid container. Through a combined structure of the main container, the supplemented liquid container and the automatic liquid supplementing device, a function of the fruit fly trap in automatically supplementing a trapping agent is realized, and the technical problem that existing fruit fly traps need manual supplementing of the trapping agent is solved.

Description

technical field [0001] The invention relates to a trap, in particular to a trap for trapping fruit flies. Background technique [0002] Drosophila widely exists in temperate and tropical climate zones around the world. Because its staple food is fruit and yeast, and rotten fruit is easy to breed yeast, fruit flies are easy to reproduce in large numbers in orchards. [0003] Drosophila is one of the main pests that harm fruits such as bayberry and blueberry. The female fruit fly lays eggs on the mature fruit, and the hatched larvae eat the fruit, causing unevenness of the damaged fruit, juice overflow and fruit drop, which reduces the yield and quality, and affects fresh sales, storage, processing and commodity prices. Fruit flies are most common in the summer and autumn seasons when the fruits are ripe. The temperature is high in this season, which makes the traps in the fruit fly traps volatilize quickly, requiring manual replenishment of traps, which is time-consuming and...
