What prevention and cure does smelly elder sister use?

Stinky sister stink bugs, also known as bedbugs, shit bugs, etc., belong to more than 30,000 species of Hemiptera bugs, of which more than 90% are agricultural pests, characterized by flattened bodies, large and small bodies, and beak-shaped mouthparts that are suitable for piercing and inhalation. next, let's take a look at what smelly elder sister uses to control it!

Artificial prevention and cure

Adults and nymphs often live on the leaves or fruits outside the crown in the morning and evening or in overcast and rainy weather, and can be caught and killed when the dew is not dry or inactive in the morning or evening. Most of the eggs lay in the foliar egg mass, which can be easily found. During the adult oviposition period from May to August, the eggs can be examined in the orange orchard and removed in time. However, it is found that there is a black ring under the egg cover, indicating that the eggs have been parasitized by parasitic wasps, which should be preserved in the field to protect them and let them reproduce naturally so as to increase the number of parasitic wasps in the orange orchard.

Biological control

There are many natural enemies of smelly elder sister in nature, including yellow mite, parasitic wasp, mantis, spider and so on, which should be protected and utilized.

Chemical control

If there are too many insects to be solved entirely by manual control, spray with 1000 times dilution of 80% dichlorvos emulsion or 800-1000 times dilution of 90% trichlorfon crystals. If some pine alkali mixture is added to the trichlorfon liquid, the control effect can be improved, and the control effect can be better in the first and second instar nymph stage.
