摘要：采用叶碟浸叶法,研究了4种不同类型的松香含氮衍生物对小地老虎4龄幼虫的拒食活性。结果显示:脱氢枞胺对氯水杨醛Schiff碱(2i)和二氢枞酸异丙醇酰基硫脲(4b)较大地抑制了小地老虎4龄幼虫的取食,质量浓度1 g/L时2i和4b 24 h后的拒食率分别为86.12%和85.13%;脱氢枞胺对甲氧基苯甲醛Schiff碱(2b)、二氢枞酸2-羟甲基-1,3-丙二醇酰基硫脲(4c)和二氢枞酸呋喃酰基硫脲(4g)对小地老虎4龄幼虫具有较强的拒食活性,拒食率分别为52.04%、66.70%和50.48%。2i具有极低的拒食中质量浓度(AFC50),为0.04g/L,2b、4b、4c和4g的AFC50分别为0.66、0.25、1.47和0.69 g/L。脱氢枞胺(取代)苯甲醛Schiff碱和二氢枞酸酰基硫脲2类衍生物对小地老虎具有较强的拒食活性,甲氧基、氯原子和羟基对脱氢枞胺(取代)苯甲醛Schiff碱的拒食活性有明显的增强作用,二氢枞酸酰基硫脲衍生物中羟基的位置和个数对小地老虎4龄幼虫的拒食活性有明显的影响。脱氢枞酸酰胺和脱氢枞酸酰基硫脲衍生物对小地老虎4龄幼虫的拒食活性较弱,且其结构变化对小地老虎4龄幼虫的拒食活性影响较小。
The antifeedant activities of four different kinds of rosin nitrogen derivatives against Agrotis ypsilon 4 instars were investigated by using the method of leaf disc.The results showed that dehydroabietylamine p-chlorine salicylaldehyde Schiff base(2i)and dihydroabietic isopropanol acyl thiourea(4b)could almost completely inhibit A.ypsilon 4 instars feeding,and the antifeedant rates of 2i and 4b were 86.12%and 85.13%at 1 g/L after 24 hours,respectively.In addition,dehydroabietylamine p-methoxy benzaldehyde Schiff base(2b),dihydroabietic 2-hydroxymethyl-1,3-propanediol acyl thiourea(4c)and dihydroabietic furna acyl thiourea(4g)showed strong antifeedant activities against A.ypsilon 4 instars and their antifeedant rates were 52.04%,66.70%and 50.48%,respectively.The 50%antifeedant concentration(AFC 50)for 2i was 0.04 g/L,which was quite low.The values of AFC 50 for 2b,4b,4c and 4g were 0.66,0.25,1.47 and 0.69 g/L,respectively.Dehydroabietylamine benzaldehyde Schiff base and dihydroabietic acyl thiourea showed strong antifeedant activities against A.ypsilon 4 instars.Methoxy,chlorine atom and hydroxyl could efficiently increase the antifeedant activities of dehydroabietylamine benzaldehyde Schiff base.The position and number of hydroxyl groups in dihydroabietic acyl thiourea had obvious impact on its antifeedant activities.The changes in the structure of dehydroabietamide and dehydroabietic acyl thiourea had little influence on the antifeedant activities against A.ypsilon 4 instars.
