Areej Abdulkareem Alkhalaf, 2013, Ultrastructural Effects of Matricharia chamomella Extracts on Cuticle of 3rd Larval Instar of Culex quinquiefasciatus, Journal of Mosquito Research, Vol.3, No.10 71-75 (doi: 10.5376/jmr.2013.03.0010)

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.
