Severe Infestation of Tea Looper How to Cope, Find Out Here It is currently late summer and early autumn, with cool weather in the morning and evening. This year has seen more rain than usual, resulting in vigorous growth of tea plants with lush green leaves, providing rich food for tea plant pests. According to investigations into the infestation of tea loopers in Longwu tea gardens, various age groups of larvae coexist, with severe overlapping generations. In some severely affected areas of tea gardens, the older leaves have been completely consumed, affecting the growth of tea plants, which requires close attention from tea garden managers. Due to differences in cultivation and management practices among individual households, the timing of infestations and the degree of damage vary across different tea gardens, making pest control challenging. It is essential to strengthen pest monitoring through field observations and the use of trapping devices, promptly understanding the dynamics of pest outbreaks and implementing appropriate measures: 1. Turn on insect-killing lamps, taking advantage of the fact that adult tea loopers are most active between 8:00 PM and 10:00 PM. Set the operating times of the lamps accordingly, ideally using a light-controlled mode where they automatically…

The integrated approach to green precision prevention and control of major tea pests involves using core technologies such as narrow-band LED insect traps, yellow-red dual-color insect-attracting boards, and efficient sex pheromone lures to maintain target pest populations at a low level through long-term and efficient trapping. This is complemented by biological preventive measures, such as spraying inchworm virus preparations and releasing predatory mites, along with good agricultural practices to control pest populations. Finally, highly efficient, low water-soluble chemical pesticides are used as emergency measures in the event of large-scale pest outbreaks. In recent years, tea plant protection scientists have conducted extensive research on pest control techniques, developing effective green precision prevention and control technologies for tea pests. Below, we will use three of the most important pests in Chinese tea gardens—the gray inchworm, the tea inchworm, and the tea tiny green leafhopper—as examples.
