| Abstract: | It is effective to control vegetable pest Pieris rapae and Pluttella xylostella with Bacillus thuringiensis strain H3-7. More than 76% of mortality in 72 hours with dilution of 1 000-fold of BtH3-7 could be achieved. The effect of BtH3-7 on the enemies of Pieris rapae and Pluttella xylostella, Apanteles glomeratus L. and Apanteles glomeratus L. is minor. There is little difference in rate of parasiting enemies in pests between check and BtH3-7 plot which is parasited by 54% of Apanteles glomeratus L. in Pieris rapae and 86% of Apanteles glomeratus L. in Pluttella xylostella. In contrast, the phoxim plot is only 4% and 46% respectively. |
| Keywords: | Bacillus thuringiensis H3-7 strain Pieris rapae Pluttella xylostella mortality natural enemy |
