Mosquitoes are insects which are harmful to humans as vectors of various
diseases. The purpose of this research was to study the effect of aquatic media
containing plant leaves against the emergence and development of Culex
quinquefasciatus mosquito larvae. Four species of leaves (kaffir lime, fragrant
pandan, betel, vinca rosea) were used in this research. Several pieces of fresh
leaves (10 g) or the dried ones were added into a pail filled with 2 litres of clean
water or contaminated water containing faeces of goats. The pails were opened for
24 hours and closed by plastic screen afterward. Treatments were repeated three
times. The numbers of emerging larvae in the water were counted and their
development was followed until become adult mosquitos. In the media with
contaminated water, the immersion of various leaves showed lower average in the
emergence of larvae than in the media containing clean water. In average, the
lowest emergence (<10 individual) was found in water contaminated media
containing the fresh kaffir lime, fresh betel, dried fragrant pandan leaves and in
clean water media containing fresh betel, dried kaffir lime leaves. Most of the
larvae and pupae failed to become imago. Whereas larvae and pupae that managed
to be imago required a longer time in its development.
