取食感虫品种的白背稻虱若虫体内羧酸酯酶(CarE)、酸性磷酸酶(AcpE)和碱性磷酸酶(AkpE)的活力明显高于取食抗虫品种的;取食中抗和中感品种的介于取食感虫品种和抗虫品种之间。水稻不同抗性品种对白背稻虱成虫及第二代若虫上述三种酶活力的影响也有类似倾向。
The activities of carboxylesterase (CarE), acid phosphatase (AcpE) and alkaline phosphatase (AkpE) in nymphs of feeding whiteworms fed on susceptible varieties were significantly higher than those of feeding insect resistant varieties. And susceptible species ranged between feeding susceptible varieties and insect-resistant varieties. The effects of rice varieties with different resistances on the activities of the above three enzymes of adult whitebacked pest and second-generation nymphs also have similar tendencies.
