用天幕毛虫核型多角体病毒(Nucleus Polyhedrosis Virus,NPV)对黄褐天幕毛虫Malacosoma neustria testacea Motschulsky幼虫以胃毒方式进行生物测定.结果表明:NPV对黄褐天幕毛虫幼虫具有较强的致病力,幼虫感染后的死亡率与病毒浓度呈正相关.1.824×102,1.824×103,1.824×104,1.824 × 105,1.824 × 106,1.824×107 PIB/mL 6种病毒浓度接种天幕毛虫幼虫后死亡率分别为26.63%,34.78%,48.37%,72.83%,80.98%和94.57%,致死中浓度为1.096×104 PIB/ mL.接种1.824×10 7,1.824×106,1.824×105 PIB/mL浓度的幼虫致死中时分别为6.8,8.2,9.1d.
用天幕毛蟲覈型多角體病毒(Nucleus Polyhedrosis Virus,NPV)對黃褐天幕毛蟲Malacosoma neustria testacea Motschulsky幼蟲以胃毒方式進行生物測定.結果錶明:NPV對黃褐天幕毛蟲幼蟲具有較彊的緻病力,幼蟲感染後的死亡率與病毒濃度呈正相關.1.824×102,1.824×103,1.824×104,1.824 × 105,1.824 × 106,1.824×107 PIB/mL 6種病毒濃度接種天幕毛蟲幼蟲後死亡率分彆為26.63%,34.78%,48.37%,72.83%,80.98%和94.57%,緻死中濃度為1.096×104 PIB/ mL.接種1.824×10 7,1.824×106,1.824×105 PIB/mL濃度的幼蟲緻死中時分彆為6.8,8.2,9.1d.
