摘 要 ：研究了担子菌黄硬皮马勃 SclerodermacitrinumPer. 子实体提取物对3龄粘虫的杀虫活性.黄硬皮马勃甲醇-氯仿总浸膏及其石油醚萃取物在浓度为25mg·mL-1时,对3龄粘虫的48h拒食率分别为96.8%和81.3%,而其氯仿及正丁醇萃取物的拒食活性相对较弱;石油醚浸膏具有较强的毒杀作用,在浓度10mg·mL-1时,3龄粘虫的48h校正死亡率均大于80%;石油醚萃取物的触杀活性相对较弱,25mg·mL-1剂量对3龄粘虫7d内的校正死亡率小于60.0%.

Abstract:In this study the fruiting body of basidiomycete Scleroderma citrinum was investigated for its insecticidal property against 3-instar Mythimna separate. At the concentration of 25.0 mg/mL, the antifeeding rates of chloroform-methanol total extract of S.
