Why do camphor leaves grow insects in autumn?

research report on why camphor trees grow insects and their control. 1. Question: In the afternoon just after the typhoon, my mother and I took a walk on the road next to Tianning Temple. There are many trees and flowers here, which is a good place for people to rest. We stopped under a camphor tree and enjoyed its fragrance. My mother explained: "Cinnamomum camphora, as its name implies, is a very fragrant tree. People use its wood to make camphor boxes, so that clothes will not be eaten by insects. This tree probably won't have worms, right?" I appreciate this tall tree carefully. Hey, why is there a hornet's nest on this tree? When I looked again, I found that it was not a hornet's nest. It looked like something stuck together by dead branches and leaves and some white silk. There were some bugs crawling on it like spiders, and they climbed quickly, as if they didn't want people to find it. I broke off the branches of the long worm hard and saw some yellow balls wrapped in a pile of dead leaves. I really couldn't understand what this was.

With these doubts, I started an investigation on why camphor trees grow insects. Second, survey methods 1. Consult books about trees and insects, read newspapers and surf the Internet to learn about camphor trees. 2. Write an email and call the technicians of the agricultural technology department to learn about the knowledge of pests and diseases that harm trees. 3. Through other channels. Third, the investigation and information channels involved in the specific content of online camphor tree Why does camphor tree grow insect repellent function? Fruits and leaves can emit a camphor smell and have insect repellent function, but camphor tree will also suffer from pests and diseases: powdery mildew, black spot, camphor sawfly, moth moth, Anoplophora sylvestris and other pests and diseases invade camphor tree. Write an email and call the agronomist in Wang Jinming, Agriculture and Economics Bureau, and seek the answer. The reply from the agronomist in Wang Jinming: The cause of camphor tree worms and how to prevent and control any kind of plants will be harmed by pests and diseases, even poisonous plants can't escape bad luck. This is a kind of pest called moth. Prevention and control methods of moth moth: 1. In the larval stage, the nest is picked manually, the branches and leaves with insects are cut off, and the larvae in the nest are burned; 2. In the early stage of larvae, low-toxic and pollution-free pesticides are selected for control, which can be sprayed with 8% dichlorvos emulsifiable concentrate 1 times and 9% crystal trichlorfon 8 times. V. Conclusion I have come to this conclusion about the investigation report on the camphor tree worm beside the road in Tianning Temple. This is a pest that is not afraid of the smell of Cinnamomum camphora. Its name is Cinnamomum camphora. It builds a nest on Cinnamomum camphora, which is composed of dead leaves, silk vomited by insects and insect dung. The insects hide inside, and many eggs, dead leaves and branches stick to the outside of the nest, which firmly bites on the branches, causing the leaves of Cinnamomum camphora to wither. These pests are the culprit. The larvae of moth moth moth spin silk and compose leaves to form a nest, where they feed on leaves and tender shoots, and in severe cases, they will eat up the leaves of moth moth moth. The "moth moth" will break out for about three generations in a year, and new larvae will hatch around May, August and October, which is also the best time to control the moth. Therefore, the agricultural department suggested that the pest of "moth moth" should be comprehensively controlled in early August to prevent its further expansion. As the saying goes, everything has its vanquisher. Nature is like this. People don't have perfect people, so do trees. Without perfect trees, people will get sick.
