Influence of some plant extracts on the ovi-position behavior of Aedes fluviatilis and Culex quinquifasciatus

Publication date: June 2014 Source:International Journal of Veterinary Science and Medicine, Volume 2, Issue 1 Author(s): Abdulhakim A. El Maghrbi , Mohamed M. Hosni Alcoholic/acetone extracts of nine species of plants (Allium tuberosum, Apium leptophylum, Carica papaya, Cymbopogon citratus, Euphorbia cotinofolia, Melia azedarach, Ocimum canum, Ricinus communis and Tagetes erecta) were tested in respect to their influence on the ovi-position behavior of the mosquito, Aedes fluviatilis and Culex quinquifasciatus in concentrations of 100, 10 and 1mg/L. Three days after mosquito females had fed on blood of anesthetized mice and pigeon respectively, experimental and control dishes were placed into cages for 24h then number of eggs laid in each dish was counted. Alcoholic/acetone extracts of C. papaya, C. citratus and T. erecta at 100mg/L; E. cotinofolia and O. canum at 100 and 10mg/L were proved to be repulsive for ovi-position of Ae. fluviatilis. On the other hand, acetone extracts of A. tuberosum and M. azederach at 100 and 10mg/L; A. leptophyllum, O. canum, E. cotinofolia and R. communis at 100mg/L produced same effect on ovi-position behavior of Ae. fluviatilis. Alcoholic extracts E. cotinofolia, R. communis (100mg/L) and M. azedarach (100 and 10mg/L) were attractive to Cx. quinquifasciatus. Five acetone extracts (A. tuberosum, A. leptophylum, C. papaya, C. Citrates and M. azedarach) were repulsive for ovi-position at 100mg/L. Acetone extract of A. tuberosum and M. azed...
