Problems solved by technology

The larvae harm the underground leaf sheaths, tender stems and buds of leeks, bite off the tender stems and eat into the bulbs. At present, the main control methods for leek maggots are soil sterilization and pesticide spraying during the growth period. The control procedures are cumbersome and prone to antibiotics. sex

Abstract

The invention belongs to the technical field of vegetable pest control and specifically relates to a method for preventing and controlling Chinese chive maggot. Specifically, the method comprises the following steps: planting Chinese chives in the manner of trench sowing; planting Chinese chives on trench; paving a layer of adhering plates at the trench bottom within four periods, including the middle ten days of April, the beginning of June, the middle ten days of July and the beginning of September; uniformly coating a layer of adhesive on the adhering plates; removing the adhering plates after 6-7 days. The method for preventing and controlling Chinese chive maggot, provided by the invention, is simple, pollution-free and low-cost.

Description

technical field [0001] The invention belongs to the technical field of pest control of vegetables, and in particular relates to a method for preventing and controlling leek maggots. Background technique [0002] Leek maggots mainly harm lily vegetables such as leeks, green onions, onions, shallots, and garlic. The tender stems are damaged, and the newly hatched larvae first damage the base of the leek leaf sheath and the upper end of the bulb. In spring and autumn, they mainly damage the young stems of the leek, causing rot, causing the leaves to turn yellow and die. In summer, the larvae move downward and bore into the bulbs. In severe cases, the bulbs rot and the whole pile of leeks dies. Generally, there are 4 generations in a year, which occur in early May, mid-June, early August and late September respectively. Overwinter as pupae, mature from late July to early August, and larvae occur in large numbers. The larvae damage the underground rhizomes of leeks in groups. A...
