Abstract: The use of natural plants products that reduce mosquito population can provide many associated benefits that limit pesticides environmental impact due to shorter latency and may be useful in preventing development of resistance. The larval mortality was observed at 24hrs and 48hrs of time exposure. LC50 value was calculated. Microscopic slides were prepared from live larvae and microscopic photography were done for the prepared slides and studied for visible changes. Dose mortality test observation showed the intensity of activity in a descending order as - Moringa oleifera Lam. > Catharanthus roseus Linn. > Lantana camara L.> Thyme vulgaris L. From this result we can conclude that more effective plant extracts results in more clumped/fused chromosomes. Effects of plant extract induced on polytene chromosome most frequently were structural in nature.
