Description

一种昆虫病原线虫防治韭蛆的水肥管理装置及方法A kind of water and fertilizer management device and method for entomopathogenic nematodes to control chive maggots

技术领域technical field

本发明涉及韭蛆防治技术领域，具体地说是一种昆虫病原线虫防治韭蛆的水肥管理装置及方法。The invention relates to the technical field of leek maggot prevention and control, in particular to a water and fertilizer management device and method for preventing and treating leek maggot by entomopathogenic nematodes.

背景技术Background technique

韭蛆属双翅目，眼蕈蚊科，迟眼蕈蚊属。主要危害韭菜、大葱、洋葱、小葱、大蒜等百合科蔬菜，偶尔也危害莴苣、青菜、芹菜等，是葱蒜类蔬菜的主要害虫之一。虫态有成虫、卵、幼虫、蛹，以幼虫聚集在韭菜地下部的鳞茎和柔嫩的茎部为害。初孵幼虫先为害韭菜叶鞘基部和鳞茎的上端。春、秋两季主要为害韭菜的幼茎引起腐烂，使韭叶枯黄而死。夏季幼虫向下活动蛀入鳞茎，重者鳞茎腐烂，整墩韭菜死亡。韭蛆的防治，可通过浇水的方式施加化学药剂。病原线虫可寄生于昆虫消化道内，通过释放共生菌在昆虫血液内增殖，进而导致昆虫的死亡。将药剂防治以及病原线虫施加结合起来防治韭蛆，则可减少化学药剂使用。Leek maggots belong to the order Diptera, Oculomycetidae, and Bradyophthora genus. It mainly harms leeks, green onions, onions, shallots, garlic and other lily vegetables, and occasionally lettuce, green vegetables, celery, etc. It is one of the main pests of green onion and garlic vegetables. There are adults, eggs, larvae, and pupae in the insect state, and the larvae gather in the bulbs and tender stems of the leeks. The newly hatched larvae first damage the base of the leek sheath and the upper end of the bulb. In spring and autumn, the young stems of leeks are mainly caused to rot, causing the leaves of leeks to wither 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. The prevention and control of leek maggots can be applied with chemical agents by watering. Pathogenic nematodes can parasitize in the digestive tract of insects and proliferate in the blood of insects by releasing symbiotic bacteria, leading to the death of insects. Combining chemical control and application of pathogenic nematodes to control chive maggots can reduce the use of chemical agents.
