Certain essential oils of plants are widely used as fragrances and flavors in the perfume
and food industries. They have long been used as insect repellents. Recent investigations
in several countries have confirmed that some plant essential oils not only repel insects,
but have contact and fumigant insecticidal actions against vectors and agricultural pests.
As part of an effort aimed at the development of reduced-risk pesticides based on plant
essential oils, toxicity and sub-lethal effects of ten essential oils have been investigated
using the “Tiger mosquito” Aedes albopictus and “Coconut mite” Aceria guerreronis as test
vector and agricultural pest species. In this paper the biological activities of essential oils
and their toxicity against mosquito and mite has been studied.

Toxic effect of the essential oils of Lavendula angustifolia, Bursera pencillata, Syzygium
aromaticum and Cyperus rotundus has been evaluated against the coconut mite, Aceria
guerreronis through bioassay on infested coconuts. The study has established the toxicity
of all the four oils on the mite to varying extent. L. angustifolia (EC50 = 0.09 and EC90 =
1.30 mg/nut) recorded highest acute toxicity. This is followed by B. pencillata, (EC50 =
0.12 and EC90 = 1.09mg/nut) S. aromaticum , (EC50 = 0.20 and EC90 = 1.22mg/nut) and
C. rotundus (EC50 = 0.28 and EC90 = 1.56mg/nut) respectively. The investigation further
highlighted the potential of these oils for the regulation of the coconut mite and the
prospects of essential oils of plants as a novel source of acaricides.
