| Efficacy of essential oils from rhizomes of Alpinia conchigera, Zingiber zerumbet and Curcumazedoaria to repel Sitophilus zeamais and Tribolium castaneum at 0.003, 0.03, 0.15, 0.31, 0.63 and 1.27 μL/cm2 by Petri-dish choice bioassay indicated that the most efficiency was found in C. zedoaria oils (91.5%) followed by Z. zerumbet oils (89.4%) and A. conchigera oils (78.1%). For T. castaneum, A. conchigera oil (97.4%) was the most effective one, followed by C. zedoaria oil (95.3%) and Z. zerumbet oil (93.0%), respectively. Furthermore, the residual of three essential oils were also estimated at 1.27 μL/cm2 and the results demonstrated that Alpinia conchigera and Z. zerumbet oils strongly repelled both insects till the end of experiment (8 days) while C.... |
