Abstract: To screen high efficient measures for preventing and controlling main tobacco diseases and insect pests during the production of Aphidius gifuensis, we carried out greenhouse experiments to study the effects of 5 different sizes nylon meshes, 20 single chemical agents and 3 mixing agents on preventing and controlling of main tobacco diseases and insects pests, and their impacts on the breeding of Aphidius gifuensis. Results showed that: (1) nylon net with 70 meshes and 6% Spinetoram 2000 times could effectively control Liriomyza, Thrip Cyrtopeltistenuis (Reuter), Prodenia litura (Fabricius), Hyperpara sitic parasitism and Syrphidae; (2) the mixing agents of 2% Oligosaccharins 800 times and 0.3% Calcium superphosphate solution could effectively control tobacco mosaic virus and tomato spotted wilt virus; (3) 6% Spinetoram plus 24% Myclobutanil (1:1) 2000 times and 25% Azoxystrobin 1500 times could effectively control powdery mildew; (4) the mixing agents of 6% Pseudomonas florescence, 2% Naphthylacetic acid wettable powder (WP) and 25% Metalaxyl WP could effectively control tobacco black shank and Thielaviopsis basicola. In conclusion, the above measures had little effects on Aphidius gifuensis.
