Abstract
Oils of Callistemon rigidus (bottle brush), Zanthoxylum armatum, DC. syn. Zanthoxylum alatum Roxb (timur), Azadirachta indica (neem) and synthetic repellent N, N-diethyl-meta-toluamide (DEET) and dimethyl phthalate (DMP) were evaluated for leech repellency properties and persistance on cloth. In statistical analysis, bio-repellents were found at par with DMP. Bottle brush oil afforded better protection against land leeches than timur oil, neem oil and synthetic repellent DMP at all the three concentrations evaluated. However, DEET was found superior to all the repellents evaluated and remained effective for 19.8 days at 0.93 mg/cm2 followed by 7 days and 6.3 days at 0.56 mg/cm2 and 0.37 mg/cm2 treatment, respectively, while bottle brush oil was found effective for 13 days at 0.93 mg/cm
