An investigation on the occurrence of pests at the green prevention and control tea garden in Shangyu County

The green prevention and control technology was used out in the Tianxiang tea plantation in Shangyu District(Shaoxing,Zhejiang Province),through installing inhalation solar insecticidal lamps and yellow sticky pest trap.The occurrence of pests during June 2018 and August 2020,including tea green leafhopper,tea geometrid,tea mites,tea aphids and tea thrips,was investigated,with the local Jinjia plantation without intervention as the natural occurrence pattern control.The results showed that the population of tea green leafhopper,tea mites,tea aphids and tea thrips at both tea plantations showed a single peak from August to October annually,while tea mites had its second population peak from April to May.Besides,the populations of tea mites and tea thrips were reduced under tea garden green prevention and control.No burst of tea geometrid was observed during the investigation period.Thus,green prevention and control technology is considered to be effective for controlling the population of specific insects without affecting the occurrence pattern.
