Abstract

The insecticidal properties of Hoslundia opposita Vahl (Lamiaceae) leaves' essential oil (EO) against Tribolium castaneum were investigated using contact toxicity and repellency bioassays. Mortality progressed with exposure period and ranged from 61.13% observed at 24 h after treatment (HAT) to 88.86% at 168 HAT. The LT50 (lethal time for 50% of treated adults) of H. opposita EO against T. castaneum was 10.42 h. Application of EO at 20-30 μL/30 cm(2) caused significantly (P < 0.05) higher percentage repellency than what was observed in control, 10 and 15 μL/30 cm(2) at 1 and 3 HAT, with significant repellency at 24 HAT regardless of dosage. Repellency class increased with EO dosage, with class V observed at 30 μL/30 cm(2), regardless of exposure duration. The RD50 (repellency dose for 50% of treated adults) of 15.88 and 13.37 μL/30 cm(2) for 1 and 2 HAT, respectively, was significantly higher than 0.09 μL/30 cm(2) at 24 HAT.

摘要

采用接触毒性和驱避性生物测定法，研究了对叶苞杯花（唇形科）叶精油（EO）对赤拟谷盗的杀虫特性。死亡率随暴露时间增加，处理后24小时（HAT）观察到的死亡率为61.13%，168 HAT时为88.86%。对叶苞杯花EO对赤拟谷盗的LT50（50%处理成虫的致死时间）为10.42小时。在1和3 HAT时，以20 - 30 μL/30 cm²施用EO导致的驱避率显著（P < 0.05）高于对照、10和15 μL/30 cm²，在24 HAT时无论剂量如何均有显著驱避性。驱避等级随EO剂量增加，在30 μL/30 cm²时观察到V级，无论暴露持续时间如何。1和2 HAT时的RD50（50%处理成虫的驱避剂量）分别为15.88和13.37 μL/30 cm²，显著高于24 HAT时的0.09 μL/30 cm²。
