Physical prevention and control method for blueberry fruit flies

Abstract

The invention provides a physical prevention and control method for blueberry fruit flies, and belongs to the technical field of fruit tree production management. The prevention and control method comprises the following steps of 1, pruning blueberry fruit trees from October to December according to the solar calender, and ensuring that an orchard is ventilated and pervious to light; 2, removing weeds and branches in the orchard from January to February of the next year according to the solar calender, and covering the ground of the whole orchard with reflective film, wherein the reflective film is provided with small breathable conical holes, and the small conical holes are formed by piercing the film with round nail points with the diameter smaller than or equal to 1.5 mm. According to the prevention and control method, through film coverage, it is difficult for overwintering pupae or fruit fly imagoes at ground soil cracks or in bushes to get out of the film for mating, and the number of insects in the orchard is reduced; meanwhile, the whole orchard reflects light, the dark and humid environment beneficial to egg laying of the fruit flies is changed, which goes against spawningand pupating of the imagoes which fly into the orchard from outside, and the harm of generation overlapping is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of fruit tree production management, and in particular relates to a physical prevention and control method for blueberry fruit flies. Background technique [0002] Drosophila has a strong reproductive ability and a short reproductive cycle, causing serious damage to small berries such as blueberries and raspberries. At present, the control of fruit flies in small berry orchards such as blueberries and raspberries is a worldwide problem. With the expansion of scale and the growth of cultivation years in my country's main blueberry production areas, the damage of blueberry fruit flies has become more and more serious. The damage rate of mature fruits in blueberry industrial bases in the southern region has reached more than 80%. [0003] In the past ten years, various places have invented prevention and control measures such as trapping and killing with various sweet and sour liquids and sex inducers, stickin...
