Embodiment 196

[0012] Example 1 The control effect of 96% pyrimepeptidemycin original drug on whitefly in greenhouse

[0013] The test agent: 96% pyrimipeptidemycin original drug, the preparation method of the 96% pyrimpeptidemycin original drug refers to the patent number 200510045975.7);

[0014] The source of the tested insects: whitefly adults in the greenhouse that had first eclosion for one day, and the wild population was collected from the tobacco of Shenyang Agricultural University, Liaoning Province;

[0015] Test conditions: temperature: 25±3°C, humidity: RH 67%, light: L:D=14:10

[0016] Test method: feeding method. 30 μg / mL and 18.75 μg / mL were formulated with 30% sucrose solution of 96% pyrimipeptidemycin as the artificial feed containing the drug. Take a glass tube with a diameter of 3 cm, cover one end of the tube with a thin layer of parafilm, drop 160 μl of medicated artificial feed on the film, and then cover with a layer of parafilm, insert 40 whiteflies in the greenhou...

Embodiment 2

[0020] Example 2 Pyrimipeptidemycin is used as the control effect of active ingredient on whitefly in greenhouse

[0021] Reagent for testing: 2% pyrimepeptidemycin aqueous solution (purchased from Shenyang Hongqilin Co., Ltd.)

[0022] The source of the tested insects: Greenhouse whitefly adults that have just emerged for one day, and the wild populations were collected from the tobacco of Shenyang Agricultural University, Liaoning Province

[0023] Test conditions: temperature: 25±3°C, humidity: RH 67%, light: L:D=14:10

[0024] Test method: feeding method. Dilute 2% pyrimipeptidemycin aqueous solution with 30% sucrose solution to four concentrations of 2, 1.5, 0.9, and 0.5 mg / mL sequentially, as artificial feed containing medicine. Take a glass tube with a diameter of 3 cm, cover one end of the tube with a thin layer of parafilm, drop 160 μl of medicated artificial feed on the film, and then cover with a layer of parafilm, insert 40 whiteflies in the greenhouse into the t...

Embodiment 3

[0028] Example 3 Bioassay Test of Controlling Greenhouse Whitefly

[0029] Reagent for testing: 2% pyrimepeptidemycin aqueous solution (Shenyang Hongqilin Co., Ltd.)

[0030] The source of the tested insects: Greenhouse whitefly adults that had first eclosion for 7 days, and the population was collected from the tobacco of Shenyang Agricultural University, Liaoning Province;

[0031] Test plants: Tobacco, Jiyan No. 9;

[0032] Test conditions: temperature: 25±3°C, humidity: RH 67%, light: L:D=14:10

[0033] experiment method:

[0034] Dilute 2% pyrimipeptidemycin aqueous solution with 0.1% Tween-80 to 0.625mg / mL, spray the prepared drug evenly on the surface of tobacco (Jiyan No. The leaf cage is clamped on the blade, and 2 pairs of female and male greenhouse whiteflies that have first eclosioned for 7 days are introduced into the leaf cage clamped on the blade, and repeated 12 times. The control group was sprayed with 0.1% Tween-80. After 24 hours, the survival status wa...

Abstract

The invention relates to an insecticidal application of antibiotic cytosinpeptidemycin to whiteflies. The cytosinpeptidemycin has a poisoning effect on whiteflies. An agricultural bactericide preparedby taking cytosinpeptidemycin as an active ingredient has a poisoning effect on whiteflies. Cytosinpeptidemycin is used for preparing a stomach poisoning agent and is used to control whiteflies, andthe effective concentration of cytosinpeptidemycin on controlling whiteflies is 30-18 [mu]g / mL. When the environment-friendly bactericide is used for controlling whiteflies in a greenhouse, the drug resistance of whiteflies is retarded, and meanwhile, part of fungal diseases and plant virus diseases can be controlled.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to the insecticidal application of the agricultural antibiotic pyrimpeptidemycin on whitefly. Background technique [0002] Greenhouse whitefly Trialeurodes vaporariorum It was invaded and settled in our country 60 years ago, and it has aggravated in recent years. For a long time, the control of greenhouse whitefly has been dominated by chemical control, coupled with the characteristics of the generation overlap of greenhouse whitefly, the resistance of the greenhouse whitefly population has been significantly enhanced. On the other hand, the abuse of chemical pesticides has also caused its natural enemies A large number of deaths have seriously damaged the ecological balance. Therefore, in the control of whitefly, it is urgent to find new agents to overcome the current situation of increased resistance to conventional agents, while taking into account the safety o...
