The present study aimed to estimate the effect of botanical extracts on the cuticle of the 3rd larval instar of Cx. quienqufasciatus, by using the LC50 of the methanol extract of Matricharia chamomella for periods of 6 hours,12 hours, 24 hours and 48 hours. The ultrastructural studies on the cuticle indicated that the larva were affected according the time elapse after exposure to the LC50 of the extracts, these effects appeared in separating epicuticle from cuticle, then the spaces between the epicuticle and exocuticle were increased after 12 hours.
