With the aim to assess its biological activity, three extracts of a Chilean endemic plant, Lepechinia chamaedryoides (Balb.)Epling (polar extract, resinous exudate and essential oil) were evaluated for its insecticidal activity on Diptera larvae,Drosophila melanogaster Meigen. The bioassay was conducted on the basis of a completely randomized experimentaldesign with 15 treatments and three repetitions, which includes the study of mortality variables and 50% lethal concentration(LC50) and 90 % (LC90), in addition to the observation of organisms through a magnifying glass, optical microscopy andtransmission electronic microscopy. Mortality was recorded over than 90 % in four tested concentrations of essential oil.In the case of polar extract ...
