Abstract
The seed extract of Himalayan shrub, timru (Zanthoxylum alatum) has been tested for its lousicidal properties against tropical hen louse, Lipeurus lawrensis tropicalis Peters. Its lousicidal properties varied with respect to dilution and exposure time. The undiluted extract and its 1:1 dilution caused 100% mortality within 12 hrs. Its further dilution 1:5, 1:10 and 1:100 could cause 93.3%, 83.3% and 56.7% mortality in 48 hrs.
