The utility model is used for the suction collection of small volume insects, such as thrips, whitefly and the like small volume insects, provides suction force through air suction pump, and air suction hose can realize the operation of various angles, and intermediate connecting pipe is used for connecting air suction hose and insect collecting tube, in order to facilitate production insect collecting tube, avoids the escape of insects, and gauze is fixedly set in the end part, prevents the escape of insects that are sucked into insect collecting tube, and the number of collected insects and the monitoring of insect state are more convenient to observe with the transparent pipe of insect collecting tube, and the tail end opening is plugged after single collection is completed.

This invention discloses a class of compounds and their uses, belonging to the field of agricultural technology. The compounds provided by this invention have excellent inhibitory activity against insect eggs, especially against the eggs of thrips, mites, lepidopteran moths, whiteflies, and ladybugs, and also have fungicidal activity. Compounds with this structure can be used to kill insect eggs and fungi, and have high research value in pesticides, with broad application prospects in the field of pesticide science.

This invention relates to a method for propagating the Japanese ladybug and its application, belonging to the field of insect population propagation technology. The method for propagating the Japanese ladybug includes introducing Japanese ladybugs to lay eggs on eggplant leaf discs, which hatch into larvae; feeding Mediterranean mealybug eggs in a culture dish to obtain adult Japanese ladybugs; mating and egg-laying in a concentrated manner to obtain Japanese ladybug eggs; and repeating this cycle to complete the propagation of the Japanese ladybug. The Japanese ladybugs propagated by this invention show significantly improved growth, development, and reproduction, with a significantly increased survival rate, and their predation ability against whiteflies is comparable to that of natural populations.

This invention relates to the field of pest control technology, specifically a method for jasmine cultivation using high-density mesh netting for pest control. The method includes the following steps: scaffolding construction; mesh netting coverage; mesh netting fixation; operation management; film pressing line fixation; and windproof reinforcement. This invention constructs a scaffolding structure and covers it with 30-150 mesh high-density insect-proof mesh netting. The bottom of the mesh netting is buried in the soil and compacted. The seams are secured with double stitches or snap fasteners, forming a fully enclosed physical barrier that completely blocks the entry paths of adult beet armyworms, jasmine flower borers, whiteflies, and spider mites. This eliminates the need for any chemical pesticides during the jasmine harvesting period. It solves the problems of overlapping pest generations leading to no safe interval, excessive pesticide residues, and interference with fragrance in traditional cultivation. This method ensures that jasmine pesticide residues meet EU export standards, significantly increases the content of key aroma substances, and produces intact, deformed flower buds.

The application discloses a coumarin derivative, a preparation method and application thereof, and belongs to the technical field of agricultural pest control. The coumarin compound has a structural formula shown in formula (I) and is recorded as COUM-N. In the formula (I), R is hydrogen, halogen, methoxy or hydroxyl. The coumarin compound is a target type natural environment-friendly compound for killing whitefly, and has little harm to human bodies and the environment.

This invention provides a compound that exhibits excellent inhibitory activity against insect eggs, and in particular, has very strong inhibitory activity against the eggs of thrips, mites, lepidopteran moths, whiteflies, and ladybugs, as well as bactericidal activity.

The application discloses a primer combination for simultaneously detecting multiple plant viruses invading tomatoes, a kit and application thereof, and belongs to the technical field of plant virus detection. In view of papaya virus E, a newly discovered RNA virus invading tomatoes in production, and tomato yellow leaf curl virus, a DNA virus also transmitted by whitefly, the application designs a kit for simultaneously detecting papaya virus E and tomato yellow leaf curl virus in whitefly, so that the whitefly virus-carrying condition can be detected, and early warning and early prevention and treatment of the two viruses can be realized. In view of a tomato sample, the application also designs a kit capable of simultaneously detecting papaya virus E, tomato yellow leaf curl virus, tomato spotted wilt virus and tomato brown rugose fruit virus in tomatoes, so that accurate and efficient detection can be performed on the four virus complex invasions and actual occurrence conditions of tomatoes.
