Life habits Jiangxi, Hunan, Guangdong and other provinces are born 3 generations old, with mature larvae in the tea leaves rhizosphere deciduous and surface soil in winter. The Xiushui River in Jiangxi Province has been demobilized in April and has emerged as a moth in May. Each generation of larvae entered the end of May, early June, early July, late July and mid-September. The victims were heavy from July to August. Adults like to eclosion and activity around dusk, and they can mate 1–3 times that evening. Two to fourteen hours after mating, the female moths lay their eggs on the leaf near the lower edge of the tea bush, with one leaf per leaf, two individual eggs, and an egg-laying amount of six to 18 grains. Adult phototaxis is strong. The larvae were dispersed and the larvae were 6 instar. After being matured, the larvae climbed to the place where the tea leaves were planted at the soil, or the leaves were planted and dissipated. Natural enemies include parasitic flies, ichinoia, fungi, and viruses.
Prevention methods (1) When tea trees are cultivated in the winter, 6.5 cm of top soil layer under the tea bushes is combed and turned into the bottom of fertilization to effectively eliminate overwintering mites, such as teat moths, flat moths, and tea silkworms. Tea cones 10cm high, can prevent overwintering and emergence. (2) For other methods, see Mulberry Pests.
