Embodiment 1

[0026] Example 1 Preliminary test on the control of oak garden pests.

[0027] Before carrying out the pest control in the oak garden, carry out relevant pre-experiments in the laboratory. The test was completed in the test base of Sericulture Science Research Institute of Liaoning Province. The medicament components are A, AB, AC, AD, AE, AF, ABC respectively. The dosage of malathion in 15L water was 0.35 g~3.5 g. 10 1-2 instar tussah silkworms were placed in disposable lunch boxes or insect cages, and 10 tussah silkworms in the 1st and 2nd instars were placed, and 2 replicates were made for each treatment. The room temperature is 25°C, the relative humidity is 70%, and the temperature is 27°C during the outdoor test. 24 hours after spraying the pesticide, the control effect was investigated. Spraying water was used as the control treatment. Correction control effect is statistically calculated according to conventional experimental methods.

Embodiment 2

[0031] Example 2 Prevention and control of the larvae of the broad-winged beetle in the oak orchard.

[0032] The experiment was carried out in the oak garden in Xiuyan County, Anshan City, Liaoning Province. In the experiment, the drug was administered once in the afternoon during the peak period of the occurrence of young nymphs of Carina pachygnathus (August 8). The components of the medicine are A, AB, AC, AD, AE, AF, ABC, and the dosage of buprofezin in 15 L of water is 0.35 g~15.0 g. Spray evenly with a knapsack-type manual sprayer. On the oak tree, there are mainly concave-winged beetle larvae, a small amount of black beetle beetle, adult stinkbugs, stinkbugs, and silkworm katydids. The day of spraying was cloudy, and the average temperature was 29.5°C; There was no rain for 2 days after the medicine. 24 hours to investigate the effect of prevention and control. Correction control effect is statistically calculated according to conventional experimental methods.

Embodiment 3

[0036] Example 3 Prevention and control of black scapularia, stink bugs, and silkworm katydids in the oak garden.

[0037] In the tussah silkworm farm in Xiuyan County, Anshan City, Liaoning Province, A buprofezin and its different ratios with B buprofezin, C dimethoate, D malathion, E pirimiphos-methyl, F sulfoxaflor In the control effect test of the combination on the black scapularia, stinkbug and katydid, the dosage of buprofezin in 15 L of water was 0.35 g~15.0 g. Above 3 kinds of components are processed by the ratio shown in table 2, and test method is all the same as embodiment 1.

[0038] Table 3 Field control effects of buprofezin and combined pesticides on black scapularia, stinkbug, and katydid

[0039] .

[0040] It can be seen from Table 3 that buprofezin A and its combination with B, C, D, E, and F in different ratios have better control effects on black scapularia, stinkbug, and katydid in the wild. It shows that buprofezin alone or in combination with oth...

Abstract

The invention relates to the field of pesticide application, in particular to application of buprofezin serving as an effective component to prevention and control of pests (tussah pests and oak tree pests) in a tussah garden. The buprofezin pesticide provided by the invention is suitable for effectively preventing and treating predatory and phytophagous pests with chewing mouthparts, hemiptera mouthparts and sponging mouthparts, such as coleoptera, hemiptera, lepidoptera, diptera, homoptera, orthoptera, mantis, hymenoptera and araneae in a tussah garden on the premise of ensuring the safety of tussah, and is particularly suitable for preventing and treating Calosoma maximoviczi Morawitz, Parena cavipennis Bates, Pinthaeus humeralis Horvath, arma chinensis, tetfigonioidea and Xylodrepa sexcarinata.

Description

technical field [0001] The invention relates to the technical field of pesticide applications, in particular to the application of a pesticide with buprofezin as an active ingredient to prevent and control pests in tussah gardens in tussah silkworm production. Background technique [0002] Oak leaves are the favorite food of tussah silkworms. Tussah silkworm is a kind of wild silkworm with important economic value. The growth and development stage of its larvae is completed on the oak trees in the oak garden. In the natural environment in the wild, pests in the tussah garden (tussah pests, oak tree pests) pose a serious threat to the normal growth and development of tussah silkworms, such as: black broad-shouldered carapace, concave-winged broad-jawed carapace, stinkbug, stinkbug, and silkworm The invasion of tussah silkworm by predatory pests such as katydid, Qingya star bug, and four-star burial insect, and herbivorous oak tree pests compete with tussah silkworm for eatin...
