Embodiment 1

[0027] Embodiment 1, see attached figure 1 , where the ordinate is the number of leaf beetles (head / plant), and the abscissa is the number of different host plants, where the labels a and b on the histogram mean: the same label means no significant difference, for example, the label a on Chinese cabbage and the label on cabbage Mark a represents no significant difference between the two, while mark a on Chinese cabbage and mark b on Rumex wrinkled leaf represent significant difference.

[0028] Indoor measurement results of the feeding preference of the little ape beetle to different host plants

[0029] Select host plants: Chinese cabbage, cabbage, mustard greens, Chinese cabbage, sorrel wrinkled leaves, the above plants are in good growth condition and keep the same leaf age. Take one plant of each of the above-mentioned 5 kinds of plants, and place them equidistantly on the five edge positions of the circular cultivation net cage, and the distance between the plants and th...

Embodiment 2

[0033] See attached figure 2 , where the ordinate is the number of leaf beetles (head / plant), and the abscissa is divided into 7 groups on the basis of 0 day, 3 days, 6 days, 9 days, 12 days, 18 days, and 30 days, and each group has a place of blank treatment. Plot A, plot B treated with Beauveria bassiana, plot C treated with phoxim, and plot D treated with R. rugosa.

[0034] Effects of Different Treatments on Controlling Ape Beetle on Cabbage Crops in Field Experiment

[0035] Select 4 vegetable plots with relatively consistent habitats, numbered plot A, plot B, plot C, and plot D, each plot is 4 mu, and the distance between them is greater than 5km.

[0036] The cabbage plants were drilled in the fields with a plant spacing of 25 cm. Among them, plots A, B, and C are all planted with cabbage.

[0037] Cabbage is planted in plot D, and a 1.0mX1.0m non-crop planting area is vacant at a distance of 8-10m among the cabbage plants.

[0038] Wherein A was used as a blank co...

Abstract

The invention discloses a method for preventing and treating brassicaceous vegetable leaf beetle type pests through rumex weeds, and mainly solves the problems that due to the adoption of chemical pesticide for treating the brassicaceous vegetable leaf beetle type pests, brassicaceous vegetables are easy to pollute and the treating effect is poor. According to the method for preventing and treating the brassicaceous vegetable leaf beetle type pests through the rumex weeds, the rumex weeds are used for trapping and killing the leaf beetle type pests, so that the vegetables are difficult to pollute, and the treating effect is good.

Description

technical field [0001] The invention belongs to the field of pest biological control, and in particular relates to a method for controlling cruciferous vegetable leaf beetle pests by sorrel weeds. Background technique [0002] Vegetable leaf beetles include flea beetles, flea beetles, flea beetles, black-backed flea beetles, and ape beetles and other coleopteran pests of the Chrysoplastidae family. They occur frequently in spring and autumn every year, and the damage is more severe in autumn than in spring. Vegetable leaf beetle mainly harms cruciferous vegetables such as green vegetables, cabbage, radish, and rapeseed. It eats the mesophyll, causing holes and defects in the leaves. In severe cases, the leaves are eaten up, leaving only the petioles, which affects the growth and quality of vegetables. Leaf beetle is also the medium of many diseases of vegetables, such as soft rot and viral diseases. [0003] At present, the control of leaf beetle pests is mainly based on ch...
