| Abstract: | The appetite and body weight increment of infected cabbage caterpillar were obviously lighter than CK.After infected 72h,the appetite of 3rd instar cabbage caterpillar's inoculanted by 2×107 conidia/ml and 8×107 conidia/ml reduced by 18.3% and 31.7% respectively than CK with by 9.8% and 16.4% for 4th larvae.The influence was stronger as dosage increasing. |
