AI Technical Summary
The existing technology lacks effective methods for controlling white grub pests, especially because of their underground living habits and insensitivity to low-toxic contact pesticides, which makes control difficult.
Use ground cloth to cover the soil surface and use pesticide for ground treatment. The weight of the ground cloth should be no less than 90g/m2. The pesticide should be diluted and then double diluted. Spray it between 6 and 7 pm to prevent and control the grubs according to their activity characteristics of entering and exiting the soil day and night.
The ground cloth physically blocks the damage caused by white grubs emerging from the soil, reduces the contact of pesticides with crops, improves the prevention and control effect, reduces the amount of pesticides used, and achieves green prevention and control.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of pest control, and in particular to a comprehensive control measure for scarab beetle pests based on circadian rhythm. BACKGROUND
[0002] Integrated pest management refers to the coordinated use of multiple strategies in control to optimize the control of all categories of pests in an ecologically and economically reasonable manner. In agriculture, there are many benefits to using integrated pest management, such as reducing the amount of pesticide used, protecting the environment and human health, and saving economic costs for farmers in the long run. However, there are still challenges in implementing integrated pest management, and the lack of control measures is one of the difficulties.
[0003] Scarab beetles are an important group of underground pests that feed on seeds, seedlings and underground tissues of plants, causing seedling death, plant growth weakness and crop yield reduction. The adult scarab beetles feed on the leaves of various plants and are an important agricultural and forestry pest. However, its control has always been a difficult problem. Scarab beetles usually live underground and are not easy to find and control with pesticides, and adult scarab beetles have a hard exoskeleton and are not sensitive to low-toxicity contact pesticides. Therefore, there is an urgent need for an integrated control technology for scarab beetle pests.
[0004] The circadian rhythm of insects refers to the regularity of insect activity with the change of day and night. The circadian rhythm affects the feeding, flying and mating activities of insects. Previous studies have shown that most scarab beetle adults have a clear circadian rhythm, and if control methods can be designed according to their circadian rhythm, not only can the control effect on scarab beetle pests be improved, but also the harm to other insects can be reduced, achieving the purpose of green control.
[0005] Based on this, the present application is proposed. SUMMARY
[0006] The purpose of the present application is to provide a comprehensive control measure for scarab beetle pests based on circadian rhythm, to solve the problem of the lack of current scarab beetle pest control methods.
[0007] In order to achieve the above-mentioned purpose of the application, the present application provides the following technical solutions: The present application provides a comprehensive control measure for scarab beetle pests based on circadian rhythm, comprising using a ground cloth to cover the soil surface or using a pesticide to treat the ground surface. When the ground cloth is used to cover the soil surface, the weight of the ground cloth per unit area is greater than or equal to 90g / m 2 ; When the pesticide is used to treat the ground surface, the pesticide is sprayed after being diluted twice the normal dilution amount.
[0008] Preferably, the ground cloth is black PE weed-preventing ground cloth.
[0009] Preferably, the ground cloth laying method is that the ground cloth is fixed to the ground by special ground nails at the joints and edges.
[0010] Preferably, the pesticide is used in a ground spraying manner, and the pesticide has a transpiration effect.
[0011] Preferably, the pesticide is used at six to seven o'clock in the evening.
[0012] Preferably, the normal dilution ratio of the pesticide is 2000-4000 times, and the double dilution ratio is 4000-8000 times.
[0013] Preferably, the pesticide is sprayed 2-3 times.
[0014] Preferably, the scarabaeiform pest has a diurnal and nocturnal soil entry habit.
[0015] The present application has the following beneficial effects by adopting the above technical scheme: the present application provides two comprehensive prevention and control methods for scarabaeiform pests based on diurnal and nocturnal rhythms, and the scarabaeiform pests are prevented and controlled by using ground cloth and pesticide ground treatment. Among them, the ground cloth covering treatment utilizes the high physical strength of the ground cloth, and physically blocks the emergence of the scarabaeiform pests. The pesticide ground treatment is sprayed at six to seven o'clock in the evening, and is sprayed on the soil surface and weeds, thereby increasing the contact opportunity of the pesticide with the scarabaeiform pests, and reducing the direct contact of the pesticide with crops, thereby reducing pesticide residues. Both prevention and control methods achieve the prevention and control effect while reducing the use of pesticides, and provide a new strategy for pest comprehensive prevention and control.

[0017] The technical solutions provided by the present application will be described in detail below in combination with examples, but they should not be understood as limiting the scope of protection of the present application.
[0018] Example 1
[0019] The implementation site is in a kiwifruit orchard in Chibi City, Hubei Province. The test site has been planted with kiwifruit since 2001. The kiwifruit is planted with a row spacing of 3 meters and a spacing of 2 meters. The harmful organism to be controlled is Popillia japonica. This beetle has a clear circadian rhythm (as shown in FIG. 1). It is in the soil during the day and comes out at night to feed and cause damage. The tarping treatment includes three repetitions. Each repetition is performed in a 6x10 meter plot. The tarping treatment is performed before P. japonica has caused damage. In this example, the tarping treatment was performed on July 26. Before laying the tarp, the overgrown weeds were first cut down using a lawn mower. The tarp used is a black PE material weed barrier with a unit area weight of 90 g / m2. The tarp is laid tightly against the ground. The joints and edges of the tarp are fixed with special ground nails at a spacing of 20 to 30 cm (as shown in FIG. 2). The number of adult beetles in each plot was investigated after P. japonica began to cause damage. This investigation was conducted from 9 pm to 10 pm on August 25. Figure 1 Figure 2
