In the year of the great occurrence of chestnut bee, chestnut trees were the most affected, and some trees had more than 10,000 chestnuts. However, the disease is not as severe in some years. The reason is that the chestnut bee has a body length of 4 mm, which is 4 mm in length and is thin, with both ends pointed, and the body is ventral to the inside. Curly, with yellow-brown sparse fine hair, lively small meat worms, which is the larvae of the long-tailed wasp. After copulation of the adult wasp larvae, the young larvae of the larvae are searched for the larvae of the larvae. The ovipositor is then inserted into the tumor. The ovary is produced on the wall of the larvicidal larvae room and the larvae are transferred to the larvae of the larvae after one or two days. On the body, it bites the body wall of the larvae of the chestnut bumblebee to feed on its body fluids. Usually a long-tailed wasp larvae only parasitizes a larval larvae of the larvae. Therefore, the hazard rate of the larvae of the larvae is reduced where the parasitism rate is high.
Because the long-tailed wasp's larvae have long lived in the tumors of the gallomat bee and have lived together with the larvae of the galliform bee for a long period of time, people often mistake the larvae of the long-tailed wasps for the larvae of the schistosomiasis bees. . In this way, it is not scientific to remove the tumor shoots during winter pruning. It is necessary to protect and use the long-tailed wasps. In the high-parasitic area of ​​the chestnut, the dry-knuckles that are cut every winter are properly kept and put in the chestnut garden from April to May to make them spawn again. In the neoplasm, control of spraying at this time to prevent killing long-tailed wasp, and then burn the stem tumor, can reduce the harm of the gall tumor bee, the natural parasitism rate of long-tailed wasp can reach 40%. The adult Chlamydomoma beetles prefer to spawn in the canopy on the shoots of thin, weak branches that are closed without wind and rain. Therefore, when the pruning is performed, the thin and weak branches must be completely removed, and the overwintering larvae in the buds can be effectively eliminated. Cut off the tender green tumor in the summer and burn it and bury it deeply. When insecticides are used, the adult and spawning period of the long tail wasp should be avoided.
How to prevent and treat cancer
The chestnut bee, also known as the chestnut bee, is a small bee capable of reproduction, having a body length of 2 to 3 mm and capable of parthenogenetic reproduction. The spawning point of the Papilloma bee is mainly in the top bud or leaf of the annual branch of the chestnut tree. The larvae of the Papilloma bees are parasitized in the neoplasms attached to the new shoots. Within each tumour, there are 1 to 13 larvae, mostly 2 to 5 heads. The chestnut bee specifically harms the young shoots, leaves, and branches of chestnut trees, and forms chestnuts on branches, petioles, and veins. This makes the chestnut tree not only unusable in the year, but also affects the results of the next year, which can make the entire branches dry and die. Even out of production. Therefore, the fruit grower said that the chestnut bee is a "cancer" that grows on the chestnut tree.
