Causes of outbreak of tea inchworm and its pollution-free control
Tea inchworm, also known as Archworm, measure-inch worm, hanging filariasis, belongs to the family Lepidoptera. The pest is mainly distributed in Bihu, Lixin and other tea areas in Liandu District. It is a kind of overeating pest. If the prevention and control is not in time, the output of summer and autumn tea will be seriously reduced, and the tree potential will decline, which will seriously affect the tea production. It happened every year in the past few years, but it didn't do much harm. In August 2007, the insect occurred in a large area in the tea garden in Huangling, Lixin Township, which not only seriously affected the tea yield in that season, but also caused tree potential decline and poor cold tolerance.
