Description

technical field [0001] The invention belongs to the field of pest control, and in particular relates to a method for controlling tea plant pests by using Beauveria bassiana. Background technique [0002] Beauveria bassiana is an entomogenic fungus of the ascomycete class. The main species include Beauveria bassiana and Beauveria b. bassiana. It often produces conidia through asexual reproduction. The hyphae have transverse septa and branches. The distribution range of Beauveria bassiana is very wide. Beauveria bassiana has been found in mountains ranging from a few meters above sea level to more than 2000 meters. Beauveria (non-ribosomal polypeptide toxoid), oosporin (benzoquinone toxoid) and calcium oxalate crystals are produced, which can cause insect poisoning, disrupt metabolism and cause death. [0003] The conidia of Beauveria bassiana begin to germinate on the host epidermis, stomata, or digestive tract under suitable conditions, and form germ tubes. At the same tim...
