Comparative mosquito repellency of essential oils against Aedes aegypti (Linn.), Anopheles dirus (Peyton and Harrison) and Culex quinquefasciatus (Say)

Toxicity and biochemical efficacy of chemically characterized Rosmarinus officinalis essential oil against Sitophilus oryzae and Oryzaephilus surinamensis

“…In the present investigation, LC 50 valves of R. officinales EO against the S. oryzae was slightly higher than the earlier report by Lee et al, 2001. Such variation in toxicity could be due to the variation in active ingredients and their ratio, mode of application, rate of vapor release, level of sorption, environmental factor (ambient temperature and air humidity), age and vitality of the insect pest (Papachristos and Stamopoulos, 2002;Burt, 2004;Phasomkusolsil and Soonwera, 2011). In general, the biological effectiveness of EOs is related to their different chemical constituents (major, minor and their mutual ratios) acting either synergistically or antagonistically with major components (Hummelbrunner and Isman, 2009;Pavela, 2014Pavela, 2014.…”

Clove Oil Efficacy on the Red Spider Mite, Oligonychus coffeae Nietner (Acari: Tetranychidae) Infesting Tea Plants

“…Clove oil is also reported to be an excellent larvicide, pupicide, adulticide, repellent, oviposition deterrent and ovicide against two mosquito vectors (Aedes aegypti, Aedes albopictus and Culex quinquefasciatus) (Phasomkusolsil and Soonwera 2010Soonwera , 2011Soonwera , 2012Shapiro 2011;Bhat and Kempraj 2009).

Mosquito repellent from Thai essential oils against dengue fever mosquito (Aedes aegypti (L.)) and filarial mosquito vector (Culex quinquefasciatus (Say))

“…However, C. odorata oil also showed excellent repellent activity against the mosquito species tested with 98.94 to 99.20% protection for 86 to 126 min. Moreover, C. odorata oil also exhibited high potential for oviposition-deterrent and ovicidal action against A. aegypti, C. quinquefasciatus and A. dirus (Phasomkusolsil and Soonwera, 2012). The essential oil of C. odorata flowers has been shown to possess repellency against mosquito bites (A. aegypti) and two grain storage insects, Sitophilus zeamias and Tribolium castaneum (Trongtokit et al, 2005;Nerio et al, 2009;CaballeroGallardo et al, 2011).…”
