Small white worms appeared on the succulents, mostly outbreaks of scale insects. Scale insects are the most common pests of indoor potted flowers, mainly parasitic on the young stems and leaves of plants. The sap is sucked by inserting a stinging mouthpiece into the plant tissue, and the wound is highly susceptible to disease. The secretion of scale insects can also lead to the occurrence of black mold.
Scale insects have a strong reproductive ability and can reproduce for many generations a year under excellent indoor environmental conditions. The eggs hatch into nymphs, and after a short period of crawling, they form a shell, which has a common feature of having a hydrophobic waxy shell on the outside of the body. Generally, insecticides are difficult to enter, and it is difficult to prevent and control, and it is not easy to remove them once they occur.
When it occurs in small quantities, it is usually controlled manually. Gently brush off with a soft brush and rinse off with water. The control of pesticides should be based on the occurrence of scale insects, and it is best to spray during the peak hatching period of eggs, which is not long after the nymphs hatch, and the surface of the insect body has not yet formed a waxy shell, and the agent is easy to kill. Due to the complexity of the generation of scale insects in indoor potted plants, the coexistence of adults, nymphs, and eggs can be observed at the same time. Therefore, it is very difficult to prevent and control, and it is necessary to spray once every 5 7 days, and spray more than 3 times in a row. It can be sprayed with 2000 times of 40% quick-culling emulsion, or sprayed with 50 dimethoate emulsion. When the insect infestation is too serious, it can be manually washed and then combined with spraying, and the effect is better. In order to prevent scale insects, it is necessary to pay attention to ventilation and light transmission during flower farming.
