The existing method of prevention and control of chive maggots is mainly to irrigate the roots with chemical pesticides. In order to obtain a good control effect, farmers use a large amount of pesticides, which not only easily causes food safety problems, but also easily causes environmental pollution.

Embodiment Construction
[0027] The invention provides a method for researching the predation effect of predatory mite on chive maggots:
[0028] Prepare the predation experiment chamber, connect the predatory mite adult mites and chive maggots into the predation experiment chamber, provide water source for the predation experiment chamber, and conduct the following research:
[0029] Obtaining the preference data of adult predatory mite to different worm states of chive maggots, processing the acquired data, and obtaining the preference index of adult predatory mite mite to different worm states of chive maggot;
[0030] Obtain the functional response data of adult predatory mite to chive maggot, process the acquired data, and establish the functional response model of predatory adult mite to chive maggot;
[0031] Obtain the predation rate data of the adult mite of the predatory mite on the leek maggot, process the acquired data, establish the predation amount model of the adult mite of the predator...

Abstract
The invention discloses a method for researching predation of predatory mites on chive maggot and relates to the field of plant protection. The method includes that the predatory mites and the chive maggot are moved to a predation lab for predation research, research on different wormlike preference, function responses, predation amount and larval predator behaviors of the predatory mites on the chive maggot are emphatically carried out, predation data of the predatory mites on the chive maggot is acquired through creative design experiments, relevant data is processed, predation related models are established, accuracy of the relevant models is verified in association with actual data, and valuable reference materials and premises are provided for biological green control of the chive maggot by taking the biological predatory mites as a medium; once the method is implemented, the problem about food safety and environment pollution generated are avoided, manpower and material resource are saved by only releasing adults of the predatory mites appropriately.
Description
technical field [0001] The invention discloses a method for researching the predation effect of predatory mites on chive maggots, and relates to the field of plant protection. Background technique [0002] Chive maggots, the name of insects, belong to the order Diptera and belong to the Oculomidae family. It mainly harms leeks, scallions, onions, shallots, garlic and other lily vegetables, and occasionally lettuce, green vegetables, celery, etc. It is distributed in Beijing, Tianjin, Shandong, Shanxi, Liaoning, Jiangxi, Ningxia, Inner Mongolia, Zhejiang, Taiwan and other places. It is one of the main pests of 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...
