Problems solved by technology

At present, nematodes are the main biological control factors for the prevention and control of tardigrades in chives, but nematodes are greatly affected by the environment, and the control effect is not ideal
At present, no one has reported the use of natural enemy insects to control tardigrade gnats and the specific release methods

Embodiment 1

[0025] Embodiment 1, release application method of dirty fly class adult

[0026] 1. Method 1

[0027] In this release application method, the released natural enemy insects and target pests are composed of the following ratios:

[0028] 1 part of adult filth fly;

[0029] 5 copies of fungus mosquito adults.

[0030] In the specification of 1 x 1.5 x 1m 3 In the enclosure, place 10 pots of leeks, each containing 20 plants of leeks. At the beginning of the experiment, the leaves above the ground of the leek were cut off, and 300 adults of the newly emerged leek tardigrade and 60 adults of the emaciated scorpion fly were put into the cage. From July to September (high temperature season), when the adult population of the tardigrade gnats on chives drops rapidly, put 15 newly emerged emaciated adults of emaciated dwarf flies into the cage every week (calculated according to the size of the area to be controlled, 30cm×30cm×1m / head). fly adults). In other months, according to...

Abstract

The invention discloses a releasing application method of a predatory natural enemy insect-coenosia attenuata imago, and provides a method for controlling bradysia odoriphaga by using coenosia attenuata. The method for controlling bradysia odoriphaga comprises the steps that in July-September, coenosia attenuata, alternative preys (providing food sources for coenosia attenuata in absence of coenosia attenuata) and a storage matrix (in place of the food sources of preys) are put into a to-be-controlled area; the putting proportion of coenosia attenuate to the alternative preys is 1 to 5-15; theputting quantity of the storage matrix is calculated according to 0.5-1.5 grams of put storage matrix of each put alternative prey; in other months in addition to July-September, coenosia attenuate is put into the to-be-controlled area, and the putting quantity takes one fifth to one twentieth of the number of bradysia odoriphaga imagoes as a standard. The insect mouth decline rate of bradysia odoriphaga of the method for controlling bradysia odoriphaga by using coenosia attenuata is significantly improved compared with that of an exiting method. The method has the advantages that the methodis simple, the sources of raw materials are wide, the purchase is easy, the investment is less, the production cost is low, and the method is suitable for promotion and application in vegetable industries.

Description

technical field [0001] The invention relates to the field of biological control, in particular to a release and application method for predatory natural enemy insects—coenosia attenuata adults, in particular to an application method for the coenosia attenuata adults. Background technique [0002] Food is food to safety first. At present, a series of problems caused by illegal abuse of chemical pesticides in my country, such as human and animal poisoning, excessive pesticide residues, agricultural product export disputes, environmental pollution and increased resistance of pests, have attracted more and more attention. Vigorously promoting the biological control of pests is a profound revolution in the concept of agricultural development. Green, ecological and healthy development has become the main theme of global development. In recent years, various localities have promoted biological pest control according to local conditions, and positive progress has been made. The bi...
