| Abstract: | Insecticidal activity of juice from Pinellia ternata and Melia azedarach and their effects on the larvae of Cabbage butterfly (Pieris rapae L.) were studied in lab .The results indicate that the juice from Pinellia ternata has the strongest stomach toxicity because its revised motality is as high as 75.8% and it possesses the best effectiveness of controlling cababage butterfly in lab, compared with the others of 82.3%. Therefore, the value of application of Pinellia ternata is to be studied further. |
