Pest control technology for pests in autumn and winter

In the fall season, various pests such as mushrooms, mosquitoes, cockroaches, worms, and nematodes can cause damage. Other small animals like snails, rats, and lice may also contribute to some extent. Effective pest control is essential to ensure healthy mushroom cultivation. During the binder fermentation phase, one of the most effective preventive measures is the use of insect nets. These nets are cost-effective, easy to apply, and help avoid drug residues. They are especially useful for general vegetable breeding, as even tiny mushroom flies cannot pass through them. In addition, low-concentration, high-efficiency, and low-residue pesticides can be applied on the material tables to prevent infestation. However, it's important to use them sparingly to minimize residue. If possible, clinker cultivation methods should be adopted. Pest control not only manages insects but also helps eliminate harmful bacteria. For species like *Agaricus bisporus* and *Agaricus blazei*, secondary fermentation at 60°C for two days can effectively kill all stages of pests, including eggs, larvae, and adults. Although this increases production costs slightly, it leads to better results in killing pests, eliminating bacteria, improving base material uniformity, and reducing unpleasant odors—offering multiple benefits. During the seed germination stage, a large number of pests can invade, typically lasting between three to five weeks. Species like *Pleurotus ostreatus* and *Coprinus comatus* have microporous bags that allow easy entry and exit for pests. To manage this, high-density screens should be used to seal vents, doors, and windows, along with closed-light cultivation to prevent adult insects from entering. Regular monitoring is crucial; if any pests are found, they can be sprayed with low-concentration pyrethroid insecticides or even just water, which can make their wings heavy and cause them to fall to the ground. When the surrounding environment is unsanitary—such as near garbage, toilets, or manure piles—it's important to clean thoroughly and install insecticides around walls and open spaces as a strong preventive measure. During the mushroom management stage, high-density insect protection nets should cover all entrances and vents. Reducing light intensity inside the shed can also help. Water management should prioritize well or tap water over stagnant water from ditches or ponds. A lime barrier of 1–2 meters wide at the entrance can prevent pests and small animals from entering. During non-fruiting periods, pyrethroids and disinfectants like formaldehyde or bleaching powder can be used to control both pests and bacteria. However, during fruiting, no chemicals should be used to avoid affecting product quality. When pests are detected, it's crucial to choose the right pesticide carefully, considering both residue levels and potential phytotoxic effects. If the infestation is light, low-residue pyrethroids can be sprayed in the air or on the surface of the substrate. For moderate infestations, eggs may be laid in the material, so immediate action is needed. For mushroom mosquitoes and springtails, an 800-times dilution of DDVP can be applied to the substrate and covered with plastic for 3–5 hours. For other insects, a 1,000-times dilution of insecticides like Broom Special or Killing Alcohol can be used, with coverage for several hours. Nematodes can be treated with a 0.5% formaldehyde solution, covered for 2–4 hours. If brown spots appear on the substrate and worm-like pests are visible on the stems, the infestation is severe. At this point, spraying is often ineffective. The best option is to use aluminum phosphide for fumigation. The method involves removing all fruiting bodies, sealing the area with plastic film, placing aluminum phosphide tablets at intervals of 1 meter on both sides, and sealing the film tightly. After 8–10 hours, the film can be removed. Before doing so, open all doors and vents first. After removal, wait 1–2 hours before taking off the plastic. Finally, collect and bury the aluminum phosphide waste deep underground to avoid environmental contamination.

Single Use Trocar Site Closure Device

A fascial closure device is a laparoscopic instrument used to close the fascia, the layer of tissue that covers and separates abdominal organs and muscles. The device is used during laparoscopic surgery to create a secure closure of the fascia after the surgical procedure is complete.

The fascial closure device consists of a needle and suture material attached to a handle. A needle is used to puncture the fascia, then suture material is passed through the puncture site and tied tightly to close the fascia. The device's handle is used to control the movement of the needle and suture material, allowing precise placement and closure of the fascia.

The use of fascial closure devices during laparoscopic surgery can help reduce the risk of postoperative complications such as hernias, wound infections, and intestinal obstruction. It also closes the fascia more quickly and efficiently, reducing the overall time required for the procedure.
