Can you see such worms in your orchard?
Protecting beneficial insects, preventing and controlling pests is very helpful, and when beneficial insects reach the appropriate amount, green prevention and control can be produced. My orchard not only sees drifting insects, but also grassflies, frogs, spiders and so on. This is the "heterochromic ladybug" among the beneficial insects can help a lot, see which pests it can prey?
Heterochromic ladybirds can prey on insects, red spiders, psyllids, shellworms and eggs, fungal spores, etc., and will also prey on homoptera, Coleoptera, Hymenoptera, diptera, Lepidoptera, and staple-eating aphids. Adult heterochromic ladybirds prey on pest larvae and can prey on 70 eggs a day. Heterochromic ladybugs will prey on pests and eggs from larvae to adult stage, isn't it very powerful?
However, it should be noted that when the amount of heterochromic ladybird is too large, it will affect other beneficial insects. Because it will prey on insect eggs, other beneficial insects will be reduced to extinction, and when the number is large, it is necessary to prevent and kill. It can be used for pesticide control, with matrine can kill about 80% of heterochromic ladybirds, inulin pesticides can kill larvae, nicotinic pesticides are safe for adults. This is determined according to the abnormal situation of heterochromic scoop, and selective medication can ensure that other beneficial insects balance each other and achieve all-round prevention and control of pests and diseases.
To protect natural enemies of pests, try to use pesticides that are harmless to natural enemies or use biological agents when preventing and controlling pests and diseases, which can protect natural hazards well and are pollution-free agricultural products.
