Abstract
Six essential oils (EOs) from Cinnamomum cassia, Citrus sinensis, Mentha piperita, Syzygium aromaticum, Zingiber cussumunar, and Zingiber officinale at 10% in soybean oil were evaluated for their repellent activities against Periplaneta americana L. and Blattella germanica L. adults and compared to that of naphthalene (1 g of sublimating ground powder), a common insect repellent. All six EOs exhibited a significantly higher effective repellency against B. germanica than against P. americana. Among all EOs tested, C. cassia EO exhibited the highest repellent activity against adult B. germanica (90.0%) and adult P. americana (76.0%). Naphthalene, on the other hand, showed 88% repellency against B. germanica and 98% against P. americana. It can repel P. americana better but repel B. germanica worse than C. cassia EO. C. cassia EO has a good potential to be developed into an effective, and safe insect repellent for controlling P. americana and B. germanica populations.
