Round shield scale. Prevention and control methods.
1) Strict quarantine. Do a good job in the quarantine of the place of origin, the insect strains need to be treated by the epidemic, and those who are not qualified for the epidemic treatment shall not be discharged and transported.
2) Strengthen management. Greenhouse cultivation should maintain a reasonable density of sparseness, not too dense, and maintain a good ventilation and light transmission environment to reduce the harm. Combined with pruning, remove insect leaves, cut off insect branches with high insect density, or scrape off scales on branches, leaves and fruits, and clean them up or use them as fuel, and do not discard them anywhere.
3) Pharmaceutical prevention and control. During the incubation period of nymphs, spray 1000 times of 40% dimethoate EC, 1500 times of 50% monocrotophos EC, 1000 times of 40% pine borer EC, 4000 times of dimetrical EC, 200 times of cometryphine, etc.
4) Pay attention to the protection and utilization of natural enemies such as ladybugs and parasitic wasps.

This is the scale insect, which is a large group, with dozens of species, and is a relatively common but troublesome tree pest that feeds on tree sap.
Pesticides can be used to kill, and if there are not many infected trees, you can take advantage of the poor mobility of scale insects and wear gloves to directly intervene by humans.

Because ** is too small, the pattern of the insect inside is too small, I can't see it clearly, and if I feel it, he is likely to be the larva of the red toon elephant. This kind of red toon image is also a variety of what we usually call a stinky big sister. It's very smelly, it's smelly, and of course some people think it's fragrant.

Native to the Amazon River Basin in South America, it was introduced to Guangdong Province in 1981 and then spread to many places across the country, due to its strong reproductive ability and adaptability, it has caused serious ecological damage in 14 provinces and cities in South China, East China, Central China and Southwest China, and is also an intermediate host for parasites such as Angiostrongylus guangdongensis. What's worse is that it takes a long time to cook Fushou snails, but the meat quality of Fushou snails that have been burned for a long time is old, and they can't chew it, so some merchants cut corners and shorten the firing time......So, the taste remained, and so did the parasites! Field snails and Fushou snails are different, so be careful!!

You forgot about the picture above. Is it white? If it is, it is powdery mildew, so put the plant in a ventilated and sunny place, and bask in the sun and ventilate it more.

It's a scale insect, it's not an egg, it's a worm. You have to buy medicine quickly**, otherwise you can reproduce quickly, you can use the scale to cure or kill the insecticide, you have to insist, otherwise you will come back to life.

The egg masses are oval, the egg grains are arranged neatly, the egg layer is not easy to fall off, the small egg masses are only a few dozen, and the large egg masses can reach more than 1,000 eggs.

The question you asked, what kind of bug is the red maple tree with white eggs on its branches?
Judging from the ** you send, it seems that it is a drilling worm, which can enter from the branch and eat it until the main trunk, which is very harmful.
The meaning of the paper cut represented by the bird standing on the branch is that instead of worrying about the future, it is better to work hard for the present, and only struggle on this road can give oneself a sense of security. >>>More
Birds, like humans, sleep with a relaxed body, but they don't fall off trees. Actually, the secret lies in the bird's legs and feet. The feet of arboreal birds, with a latch mechanism, have flexor muscles and tendons, which are ideal for grasping branches. >>>More
1.The tree with the bird is particularly vivid. I love these little birds flying from tree to tree and they dance on the branches. >>>More
In the process of metabolism, some plants will produce honey, volatile oil, mucus, resin, milk, tannins, alkaloids, salts and other substances, which accumulate in cells, intercellular spaces or cavities, or are excreted from the body through certain cell structures, this phenomenon is called secretion. The secretions of many plants have important economic value, such as rubber, lacquer, aromatic oils, honey, etc. >>>More
