Embodiment

[0022] Embodiment: A kind of new medicine of preventing and treating armyworm and its application method

[0023] 1.1 Armyworms tested

[0024] Armyworm 2nd instar larvae.

[0025] 1.2 Cyclosporin A concentration

[0026] Cyclosporin A doses: 50 μM, 100 μM and 150 μM.

[0027] 1.3 Bioassay methods

[0028] In this paper, medicament mixed artificial feed (yeast powder 34 g, wheat germ powder 40 g, corn leaf powder 100 g, mix well; 2, sorbic acid 2 g, methylparaben 4 g, 300 mL distilled water boiled and mixed well Finally, add the mixture to ① and mix well; 3. 600mL distilled water, 18 g agar powder, boil and mix well, then add to ②, stir evenly; 4. When the temperature drops to 40 ℃, add VC 2.5 g, linoleic acid (Soybean oil) 5-6 drops, mix well; store at 5, 4 ℃.) method for bioassay. That is, the armyworm artificial diet was prepared first, and before the feed was cooled and solidified, different doses of cyclosporine A were mixed into the armyworm artificial diet, and the...

Abstract

The invention belongs to the field of toxicological activity of pest control, and particularly relates to a new drug for controlling mythimna separata and a use method of the new drug. The new drug iscyclosporin A, wherein the mythimna separata refers to 2-year-old mythimna separata. The method for preventing and treating the mythimna separata by using the new drug comprises the step of mixing the new drug with an artificial feed to feed the mythimna separata. According to the invention, the cyclosporin A is mixed with the mythimna separata artificial feed, and by setting different doses of the cyclosporin A, the prevention and treatment effect on the mythimna separata is detected after 7 days. The prevention and treatment effect of the cyclosporin A is evaluated, and the prevention and treatment dosage of the cyclosporin A is determined. And a new active functional group is provided for the design of a standby insecticide or new drug for preventing and treating the mythimna separata.

Description

technical field [0001] The invention belongs to the field of toxicological activity of pest control, in particular to a new drug for preventing and controlling armyworm and its application method. Background technique [0002] Armyworm ( Mythimna separata (Walker)), belonging to Lepidoptera Noctuidae, also known as shaving insects, marching insects, commonly known as multicolored insects, wheat silkworms, is a heterogeneous polyphagous mainly eating wheat, corn, sorghum, rice and other food crops and pastures , migratory, intermittent explosive pests. There are 6 instars of armyworm larvae, and the 4th to 6th instars are the overeating period, which is the main stage of harm. It can harm more than 104 species of plants in 16 families, especially gramineous plants. Except for some areas in the Northwest, it is distributed in other places. When armyworm outbreaks occur, crop leaves can be eaten up, causing serious damage to crop growth. In recent years, armyworm outbreak...
