Abstract

The invention belongs to the technical field of pest control in garlic cultivation, and in particular relates to a method for preventing and controlling onion fly adults. The steps of the present invention are as follows: 1) carry out research on the dynamic change law of the onion fly population, grasp the occurrence dynamics of the onion fly, and determine the peak period of the onion fly occurrence; 2) after the garlic emerges, the mulch film is broken by dragging or swatting to break the film. Treatment; 3) Use blue armyworm plate for armyworm treatment during any growth process of garlic; 4) Co-control with 50% clothianidin WG and 2% high chloride and emamectin EC. In the present invention, by carrying out the dynamic monitoring of the onion fly population, the time for centralized spraying and killing of the onion fly is clarified, and the control of larvae is changed to the control of adults. and other control measures to achieve effective control of onion fly adults.

Onion fly larvae are commonly known as "garlic maggots", which are more harmful to garlic bulbs. The occurrence of garlic maggots is closely related to the growth period of garlic, cultivation measures and planting environment. Garlic maggots have the habit of avoiding light. When they are harmful, they often pierce the epidermis and eat the bulbs of garlic, causing the bulbs to become holes, incomplete, and emit a foul smell. Some fields ha...
