茶叶是我省的特产之一,由于长期使用化学农药防治害虫,严重影响了茶叶的品质,且残毒危害人民健康。过去资料报导,苏云金杆菌类对茶树鳞翅目害虫,茶毛虫、大尺蠖、茶蚕等有一定的效果,但没有较理想的菌种,1979年5月起,我们开始进行茶树害虫病原微生物的调查和筛选工作,拟选育出杀虫效率高、残毒低、生产性能好的菌株,用来防治茶树害虫,提高茶树的产量和质量。 Tea is one of the specialties of our province. Due to the long-term use of chemical pesticides to control pests, the quality of tea has been severely affected, and residual poison endanger people’s health. According to the data in the past, Bacillus thuringiensis has certain effects on lepidopteran pests, tea caterpillars, macrophylla, tea silkworm and the like, but there is no ideal species. Since May 1979, we started to carry out pathogenic microorganisms Investigation and screening work, we intend to bred strains with high insecticidal efficiency, low residue, good performance, used to control tea pests and improve the yield and quality of tea trees.
