Causes of Tea Geometrid Outbreaks and Pollution-Free Control Methods
Tea geometrid, also known as the arching worm, measuring worm, and hanging-silk worm, belongs to the order Lepidoptera, family Geometridae. In Liandu District, this pest is mainly distributed in tea areas such as Bihu and Lixin, and is a voracious pest. If control is not timely, it often causes severe reductions in summer and autumn tea yields, and leads to decline in tree vigor, seriously affecting tea production.
