Massive use of chemical based insecticides led to detrimental effects on the public healt and environment. This situation, environment
friendly and biodegradable natural products of plant
origin alternatives to synthetic larvacids
have received attention as agents for vector control. Thus, many researchers have studied on alternative methods for
pest control instead of chemical ones.
In this study, some medicinal valuable plants naturally
growing in Turkey were selected for this purpose and
investigated the larvicidal effect against Asian tiger mosquito Aedes albopictus larvae. Bioassays were carried
out by appliying late 3th to early 4th instar larvae of Aedes albopictus to two different dose
of plant extracts. The larval mortality was counted after 24 and 48 h after
experiments. Bioassay results revealed that Leucanthemum
vulgare was the most effective for ethyl acetate extract in 500 ppm
concentration, 100 % for 24 h, 100 % for 48 h. Salvia vertisillata induced a second high mortality after 24 h
treatment for two doses of both extracts. Inula
vulgaris and Matricaria chamomilla produced high and
moderate mortality for 500 ppm dose of both extracts, respecitvely.
Our results
evidenced that the high larvicidal activity was detected products obtained from
crude extracts with ethyl acateta and methyl alcohol of Salvia verticillata, Leucanthemum
vulgare, Inula vulgaris and Matricaria
chamomilla.
But need to be further study about possible candidate species for new and safer
control products against mosquito control.
