title: [Chemical composition and lethal effect of essential oil from Pimenta racemosa (Myrtales: Myrtaceae) on Blatella germanica (Dictyoptera: Blattellidae)].
abstract: Gas chromatography test and Gas chromatography/mass spectrometry test allowed examining the essential oil from Pimenta racemosa leaves (Mill.) J.W. Moore (Myrtales: Myrtaceae). A total of 26 volatile compounds representing 99.5% of the whole composition were identified, being ternipen 4-ol and 1.8 cineol those having the largest portions. Lab bioassays were performed with 5 different oil doses on Blattella germanica. DL50, 15.55 and DL95 = 48.16% were estimated by a probit-log analysis as well as diagnostic dose of 2 microg/insect of 50% oil that is recommended for field surveillance of the use of various formulations in insect control programs.
