Identification of red-brown insects The red-brown insects, with the scientific name of red spider, are a common indoor plant pest. They are tiny and reddish-brown, and usually gather on the leaves, stems or branches of succulent plants. Red spiders have extremely strong reproductive capabilities. Once discovered, if not treated in time, it can easily cause damage to the entire plant. Causes of red-brown insects 1. Environmental factors: The growth environment of succulent plants is too dry, poorly ventilated, or the temperature is too high, which can easily lead to the breeding of red spiders.
2. Improper maintenance: Maintenance problems such as excessive fertilization and improper watering can also lead to a decrease in the resistance of succulent plants, thus attracting the invasion of red spiders.
3. Plant carrying: Some healthy succulent plants may carry red spider eggs or larvae, so pay attention when purchasing. Prevention and control methods of red and brown insects 1. Clean and maintain the environment: Keep the growth environment of succulent plants ventilated and dry, regularly clean up dust and debris on the plants, and reduce the habitat of red spiders.
2. Moderate fertilization: Reasonable fertilization, avoid excessive application of nitrogen fertilizer, and maintain moderate soil fertility.
3. Appropriate watering: According to the growth habits of succulent plants, appropriate watering to avoid water accumulation in the soil.
4. Check newly purchased plants: When buying succulent plants, check the plants carefully to make sure you don't carry red spiders.
5. Physical prevention and control: Gently brush off the red spider with a fine brush or soft cloth, or immerse the plant in water and use the buoyancy of water to wash away the red spider.
6. Chemical control: When physical control is ineffective, low-toxicity and low-residue pesticides can be used for spraying. When spraying, pay attention to spraying evenly to prevent the liquid from flowing into the heart of the plant.
7. Biological control: Introducing predatory natural enemies, such as predatory mites and ladybugs, can effectively control the number of red spiders.
Red-brown insects are an important factor affecting the growth of succulent plants. Understanding their causes and control methods will help us better maintain succulent plants. In the actual maintenance process, we must pay attention to the environment, maintenance and inspection, and promptly discover and deal with the red spider problem to allow succulent plants to grow healthily.
