僵蚕提取物对棉铃虫的胃毒作用和碱性磷酸酶活性的影响
Toxicity and Alkaline Phosphatase Activity Inhibition of the Extracts from Bombyx batryticatus Against Helicoverpa armigera
摘要
Abstract
This paper reported the study results on feeding toxicity and inhibition effects on alkaline phos-phatase (ALP) of Helicoverpa armigera treated with the extracts of Bombyx batryticatus. The corrected mortality of H. armigera treated with the extracts of B. batryticatus at 3 mg · g-1 concentration in insect diet was 66. 7% after feeding on the toxic diet three days, while the corrected mortality was up to 83% to the larvae treated with a concentration of 5 mg · g-1, indicating that the B. batryticatus extracts was high toxic to the third instar larvae of H. armigera. The enzyme assay showed that the ALP activities decreased significantly while treated with the B. batryticatus extracts concentration ranged from 1 mg · g-1 to 5 mg · g-1, and the correlationship was responsible to the dosage of B. batryticatus extracts. Thus, the inhibition on ALP activity is a possible mechanism for the pesticidal activity of B. batryticatus extracts.关键词
