Published: 2024-11-08 Author: mysheen
Last Updated: 2024/11/08, The wing pattern of the adult Ligustrum lucidum is slightly like a basket of woven texture, with a wingspan of about 9-10cm, which is a large moth. The larvae are gray-black or light-colored, and there are two dorsal horns on the 2nd and 3rd segments of the body when young, and the 2nd and 3rd segments are dilated when they are nearly old, and the color around the valve is bright. The larvae can make a cackling sound in their mouth when they are disturbed. Adult Eclosion from June to July. The hosts are privet, lobular wax, Japanese privet, white wax, sweet-scented osmanthus and so on. At present, it is the period of damage to the older larvae, which we are used to seeing. Prevention and control methods:

Prevention and control methods:

The main results are as follows: 1. The artificial killing of low trees such as nursery and engineering color blocks is simple and effective.

2. Bigger trees can be sprayed with pesticides such as dichlorvos and phoxim.
