Abstract
This study was perfomed to assess the in vitro effect of oil from the seed of andiroba (Carapa guianensis Aubl.) on Felicola subrostratus (Burmeister, 1838) (Mallophaga: Trichodectidae). Six hundred specimens of F. subrostratus from neighborhood of Jordao, Recife-PE, Brazil, were collected by hand directly from the fur of cats infested naturally. The lice were transported in plastic recipients to the Laboratory of Parasitic Diseases of Domesticated Animals of the Department of Veterinary Medicine of the Universidade Federal Rural de Pernambuco (Brazil) for the immersion test. Four dilutions of andiroba oil (100, 50, 25 and 10%) in distilled water were tested, using Tween 80 as dispersant; two control groups (one with distilled water and the other with monosulfiram) were also formed; four replicates were performed, with 25 specimens for each dilution, totaling 100 lice per treatment. After the test, the insects were kept at room temperature and observed for mortality rates for 72 h. The biological activity of the product achieved 100% mortality of the insects in the first hour at concentrations of 100 and 50% and in the third hour at concentrations of 25 and 10%. The results demonstrate the possibility of controlling F. subrostratus throught the use of oil extracted from andiroba seeds.
