| 摘 要： | 研究了兴安獐牙菜全草的不同提取液对甘蓝夜蛾幼虫的触杀和拒食作用.研究结果表明,乙醇浸提液对甘蓝夜蛾幼虫具有较高的触杀作用,24,48 h的致死中浓度(LC50)分别为3.746 7,3.172 7 mg/mL.水蒸气蒸馏液对甘蓝夜蛾幼虫具有较强的拒食作用,24,48 h的拒食中浓度(AFC50)分别为5.039 9,5.216 7 mg/mL.丙酮浸提液对甘蓝夜蛾幼虫的触杀和拒食作用不显著.

| Abstract: | Contacting and anti-feeding of different extraction from the herb of Swertia diluta against Barathra brassicae through uniform design was studied. The ethanol extract had high contacting activity, the LC50 of the ethanol extract were 3.746 7 mg/mL in 24 h and 3.172 7 mg/mL in 48 h; the wet-distillation liquid had strong antifeedant activity, the AFC50 of the wet-distillation liquid were 5.039 9 mg/mL in 24 h and 5.216 7 mg/mL in 48 h. Acetone extracts had indistinctively contacting and anti-feeding. |
