Agricultural control
(1) Build water conservancy so that droughts and floods do not occur.
(2) to do a large area of wasteland reclamation planting, change the habitat of locusts, reduce the area of the base of occurrence.
(3) plant trees and forests, change the microclimate of the locust area, reduce the locust spawning and breeding of suitable places.
(4) Improvement of farming and cultivation techniques to achieve control of locust eggs, changing the layout of crops according to local conditions to reduce locust damage.
Biological control
(1) In locust-infested areas, use high-efficiency and low-toxicity agricultural and biological pesticides to protect predatory natural enemies in locust areas.
(2) Large-scale application of locust microsporidia.
Pharmaceutical control
Large-area use of pharmaceutical control of locust locust locusts should be mastered before the 3rd instar. Use 75% malathion emulsion for ultra-low volume or low volume spraying. Aircraft control with 60 to 70 grams per acre; ground spray, 75 grams per acre, or ground ultra-low-volume spraying with 45% malathion emulsifiable concentrate, 75 to 100 grams per acre, or 20% Enemy Horse Combination, 100 grams per acre, or 1.5% lindane powder, 1.5 to 2 kilograms of spray powder per acre.
