Abstract: The study aims to verify the breeding rules of aphids and Aphidius gifuensis under different positions in greenhouse and number of inoculating aphids. ‘Yunyan 87’ was used as the main test material, the experiment of different positions in greenhouse and number of inoculating aphids on breeding of aphids and Aphidius gifuensis was conducted at flue-cured seedling house in Xinfeng(107°01′33.2″E, 27°17′16.6″N), Nanmudu Town, Kaiyang County, Guizhou Province in 2015, to explore the effects of different positions (forepart and rear) in greenhouse and number of inoculating aphids (20,40, 60 piece/plant) on breeding of aphids and Aphidius gifuensis. The results showed that accumulated temperature, mean daily temperature, mean daily highest temperature of the forepart (3-4 row) were higher than that at the rear (9-10 row) of the greenhouse, but mean daily humidity of the forepart was lower than that at the rear. The number of aphids and Aphidius gifuensis breeding at the rear was more than that of the forepart, and 40 piece/plant was the maximum, followed by 20 piece/plant, 60 piece/plant was the minimum. The agronomic characters of tobacco plant at the rear were better than that of the forepart in greenhouse, and became worse with the increase of the number of inoculating aphids. The rear of the greenhouse is conducive to the production increase of aphids and Aphidius gifuensis, and also to the growth and development of tobacco, and the number of inoculating aphids with 40 piece/plant is advisable, 20 and 60 piece/plant are adverse to the breeding of aphids and Aphidius gifuensis.
