Problems solved by technology

In recent years, various regions have conducted systematic investigations on the occurrence of leek maggots every year, and the methods used to trap and monitor adult leek maggots are mainly insect trap lamps, yellow boards or sweet and sour water basins, but for leek maggots The prevention and control of chive maggots has no obvious effect, because the adult chive maggots themselves have obvious dark habits, and the light waves produced by the insect lamp and the yellow board are not suitable for trapping the adult chive maggots, and the above trapping methods also ignore The trapping effect of host plants on leek maggot adults, therefore, it is necessary to use the dark habit of leek maggot adults and the food attraction effect of host plants to find a way to effectively trap and monitor adults

Embodiment 1

[0022] A method for trapping leek maggot adults to lay eggs, the concrete steps are:

[0023] (1) Weigh 30g of Chinese chive flowers and 1g of yeast powder, mix them with a blender to form a muddy state, and ferment at 4°C for 8 hours to obtain bait materials;

[0024] (2) Adult traps are disinfected with 70% alcohol spray;

[0025] (3) Weigh 0.5g of agar powder, add 24.5g of water, heat and dissolve in a microwave oven and pour it into the adult trap. After solidification, spread a layer of filter paper moistened with sweet and sour liquid, and put the bait material in the adult trap. on the surrounding filter paper;

[0026] (4) The leek field is selected as the 3-year-old leek experimental field of the Institute of Plant Protection, Shandong Academy of Agricultural Sciences, with a total area of ​​40m 2 , adult traps with 1 / 10m 2 The density is placed in the leek field, 30cm above the ground, and the placement time is the peak period of leek maggot emergence.

Abstract

The invention relates to the field of plant protection and insect trapping and monitoring technology, in particular to a method for trapping and monitoring leek maggot adults. The bait material is prepared from leek flowers and yeast powder to trap the leek maggot adults. The present invention combines the color-taxis effect and the olfactory effect of leek maggot adults and proposes a new method for trapping and monitoring leek maggot adults. The combination of bait materials and adult traps can ensure that all adults can be trapped. The accuracy of monitoring is improved, and the harm of leek maggots is reduced at the same time, which provides a new way for the green and pollution-free production of leeks.

Description

technical field [0001] The invention relates to the field of plant protection and insect trapping and monitoring technology, in particular to a method for trapping and monitoring leek maggot adults. Background technique [0002] Chive maggots are the larvae of Chive maggots, which belong to the genus Pleurophyllidae of Diptera Longoceraphyta. , Compositae, Chenopodiaceae, Cruciferae, Cucurbitaceae, Umbelliferae and other 7 families and more than 30 kinds of vegetables, especially leeks in the northern protected areas are the most affected, which can cause 30%-80% yield loss. Leek maggots are also very widely distributed, and occur all over the country, mainly in North China, Northeast China, Northwest China and Shandong. Leek maggots have the property of boring, and the roots, white tender stems, pseudostems, and bulbs of leeks will all be damaged and then rot. In order to increase the yield of leeks, people use a large amount of highly toxic and highly toxic pesticides, w...
