The purpose of ecological control is to eliminate conditions conducive to the reproduction of locusts. In areas where locusts are prone to occur, such as coastal beaches, lakeside areas, river flooding areas, and agricultural and pastoral areas. By planting trees and grass, reclaiming wasteland, etc., increase the area of vegetation coverage, reduce the living space of locusts, and control the locust plague.
In low- and medium-density areas, lake and reservoir water source areas, and nature reserves, use Metarhizium anisopliae, microsporidian microbial preparations, botanical pesticides, and chickens and ducks to control locusts.
(1) Biological pesticides
Metarhizium anisopliae and locust microsporidia can parasitize the locusts, cause the locusts to die, and can spread between locusts. By drone agriculture spraying metarhizium anisopliae or locust microsporidian preparations, the population density of locusts can be effectively controlled.
(2) Botanical pesticides
In areas where locusts occur in non-lake reservoir water source areas, when the density of locusts is low or sporadic, spray matrine, azadirachtin, cangolin and other plant-derived pesticides to control locusts
(3) Controlling locusts with chickens and ducks
For Xinjiang, Inner Mongolia and other northern agricultural and pastoral areas or grassland locust areas, during the locust control season, in locust areas that are not too high in altitude, relatively flat, convenient in transportation, and not far from the water source, trained chickens, the flocks of chickens or ducks can be transported there and prey on the locusts, reducing the density of locusts, and controling the damage done by locusts.
(4) Use natural enemy protection
In natural breeding areas for pink starlings in Xinjiang and other areas where locusts occur, artificially build bird nests and create habitats to lay eggs to attract pink starlings to lay eggs and brood chicks. By attracting pink starlings to prey on locusts, control the harm of locusts.
When the density of locusts reaches the control target, chemical pesticides can be used for control. Currently commonly used pesticides are: organophosphate insecticides (such as malathion), pyrethroid insecticides (such as lambda-cyhalothrin, deltamethrin).
Compared with manned aircraft, plant protection drones have the advantages of being simple, easy to learn, flexible and low-cost in locust control. At the same time, in some areas with large slopes and ravines, plant protection drones can penetrate even more complex environments to comprehensively prevent and control locusts. Therefore, as a brand-new locust control method, plant protection drones have been applied to the control of locust plagues.
The operating environment for locust control is diverse. The operating mode should be selected according to the operating terrain. If the work area is small and the terrain is complex, manual work mode can be used. If the operating area is large, the terrain is complex, and there are many obstacles, you can first carry out surveying and mapping and planning the route before flying defense operations. If the operation area is relatively flat and the plot is large, the route planning mode can be used for operation. After each landing, the carcasses and residues of locusts falling on the surface of the aircraft must be cleaned up to reduce the burden of operations. Shenzhen TitanFlying Technology Co., Ltd will pay attention to the dynamics of locust plagues and introduce corresponding measures to actively bring the experience and ideas of drones to prevent locust plagues to overseas hard-hit areas to help locals eliminate locust plagues.
