The application provides a preparation method of a cowpea leafhopper repellent and application thereof, and belongs to the technical field of green prevention and control of agricultural pests. The preparation method is as follows: activated biochar obtained by microwave pyrolysis of straw powder and activated by phosphoric acid is mixed with intercalated montmorillonite-PVA compound obtained by intercalating aluminum ions into montmorillonite and modifying the intercalated montmorillonite with polyvinyl alcohol, and then the mixture is modified with KH-550 to obtain a supported controlled-release carrier; linalool, geraniol and methyl salicylate are loaded on the supported controlled-release carrier to prepare a core; trans-2-hexenal and trans-2-octenal are loaded on the core to prepare a core-shell structure microsphere; the core-shell structure microsphere is coated with poly-N-isopropyl acrylamide to prepare a multi-stage controlled-release microsphere; and the multi-stage controlled-release microsphere is used to prepare the cowpea leafhopper repellent for preventing and controlling cowpea leafhoppers. The application improves the loading capacity and adsorption stability of active components, and improves the compatibility with the wax layer of cowpea leaves. The preparation of the application shows fast effect and long persistence.

This utility model relates to the field of insect hemolymph collection technology, and discloses a leafhopper hemolymph collection device, including a collection tube, a rubber stopper at the opening of the collection tube, a negative pressure cylinder, a liquid collection tube with an insertion needle at one end, and a positioning component for positioning the collection tube. The other end of the liquid collection tube passes through the rubber stopper and is connected to the collection tube. The rubber stopper is tightly fitted to the opening of the collection tube. An air inlet is opened at the upper part of the negative pressure cylinder, and a bent tube is fixedly inserted into the air inlet of the negative pressure cylinder. The bent tube is fixedly inserted into the rubber stopper and is connected to the collection tube. The positioning component includes an upper sleeve with an opening at the lower end, a lower sleeve with an opening at the upper end, and multiple arc-shaped positioning blocks made of elastic rubber. The purpose is to provide a device for collecting leafhopper hemolymph and to solve the problem that existing insect hemolymph extraction devices require insertion and removal of the suction hose and liquid collection hose on the sealing cap during use, resulting in a complex structure and inconvenience in use.

This invention discloses a method for large-scale breeding and preservation of the tea green leafhopper suitable for cicada tea production. Step 1: Select Jin Xuan, Cui Yu, or Fuding Da Bai tea as the host plant variety and determine the host plant specifications; Step 2: Establish adult tea green leafhopper breeding areas, nymph breeding areas, and egg incubation areas, and breed in separate zones, optimizing the optimal breeding conditions and stocking density for each zone; Step 3: Optimize the method for collecting tea green leafhopper eggs, including optimizing the adult sex ratio, egg-laying density, and egg collection time; Step 4: Establish a tea green leafhopper egg storage room and optimize the storage conditions; Step 5: Optimize the incubation conditions and incubation time for tea green leafhopper eggs after low-temperature storage. This invention's large-scale production method utilizes unpruned tea branches from tea gardens, resulting in low costs. Using tea branches for breeding reduces the mortality rate of leafhoppers needing to readjust to the host plant upon release.

The present application belongs to the field of kiwi fruit planting, and discloses a management method of kiwi fruit trees. The present application adopts a double-layer reverse U-shaped ring cutting method, which can slow down the downward transportation of photosynthetic products to a large extent and for a long time, effectively improves the yield and quality of kiwi fruit, reduces the risk of tree death, and balances the vegetative growth and reproductive growth of kiwi fruit. In addition, the present application provides a new type of composite control agent for brown spot disease and leafhoppers, which can more efficiently and scientifically control diseases and pests, thereby significantly improving the yield and quality of kiwi fruit.

The present application belongs to the technical field of biological pesticides, and particularly relates to a biological pesticide composition for preventing and treating cowpea leafhoppers. The effective component of the biological pesticide is compounded by Java Cordyceps bacteria and abamectin or spinetoram; wherein the Java Cordyceps bacteria is 500 billion spores / gram of Java Cordyceps bacteria JS001. When the Java Cordyceps bacteria is compounded with abamectin or spinetoram in the biological pesticide composition, the cowpea leafhoppers show a synergistic effect, the prevention and treatment effect can be improved, the pesticide usage amount can be reduced, and the prevention and treatment cost can be reduced.

This invention discloses a method and system for predicting the small green leafhopper in tea gardens based on a population dynamics model. The system acquires data on tea garden zoning, tea tree phenology, historical pest infestations, overwintering pest populations, and daily meteorological data to construct a structured pest life model and calculate the basic pest population dynamics for each sub-region. Combining pest monitoring with meteorological terminals, control operations and typical meteorological processes are abstracted as events. These events are triggered during model operation to correct the population state, and an assimilation algorithm is used to correct the model's predictions and observed data, yielding the posterior population state. Based on the posterior state, forward simulations of different control schemes are performed to assess pest risk and establish control windows and recommended schemes. The system consists of modules for data management, population modeling, monitoring access, event scheduling, assimilation, and prediction evaluation, enabling small green leafhopper infestation prediction and control decision support.
