摘要: 目的 了解美洲大蠊对蓖麻粗毒的嗅觉行为反应。方法 利用蜚蠊红外监测仪观察24h。结果 美洲大蠊进入装有蓖麻粗毒活动小盒的平均频次为9.67,与蒸馏水(F=5.57)和空白对照(F=5.40)差异有统计学意义(χ2=16.70,P<0.01);而美洲大蠊进入装有蓖麻粗毒活动小盒的停留时间为18.67s,与蒸馏水(15.14s)和空白对照(8.80s)差异无统计学意义(χ2=5.047,P>0.05)。结论 美洲大蠊对蓖麻粗毒有一定的正向趋性。

Abstract: Objective To learn about the olfactory behavior of Periplaneta americana to ricin. Methods The infrared sensor was employed to keep investigating for 24 h. Results There was significant difference between the average frequency of P.americana attracted to ricin (F=9.67) and that to distilled water (F=5.57) or the control (F=5.40) (χ2=16.70,P<0.01), but the retention time in the box was not significantly different (χ=5.047,P>0.05). Conclusion P.americana was positively attracted to ricin.
