Abstract
The purposes of this study are to find out the toxicity and repellency of lemongrass oil (Cymbopogon flexuosus) to the German cockroach (Blatella germanica). Study was conducted from August to October 2016 in Research Laboratories of Animal Physiology, Department of Biology, Faculty of Mathematics and Natural Sciences Andalas University Padang. This study used the glass jar method (contact) with three strains of German cockroaches (VCRU-WHO, KRS-BDG and HHB-JKT) and lemongrass oil. The average of lethal time after 6 hour exposure ware counted with a probit analysis until found value LC90. The results showed that based on value LC90 strain VCRU-WHO 15,20%, strain KRS-BDG 22,42% and strain HHB-JKT 19,28% after 6 hour exposure.

Summary
Toksisitas dan Repelensi Minyak Sereh Dapur [Cymbopogon flexuosus (Nees ex Steud.) W. Watson] terhadap Kecoak Jerman (Blattella germanica L.). Toxicity of Lemongrass Oils [Cymbopogon flexuosus (Nees ex Steud.) W. Watson] to the German Cockroach (Blattella germanica L.). INTISARI Penelitian ini bertujuan untuk mengetahui toksisitas minyak sereh dapur (Cymbopogon flexuosus) terhadap kecoak Jerman (Blatella germanica). Penelitian dilakukan pada bulan Agustus- Oktober 2016 di Labolatorium Riset Fisiologi Hewan, Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Andalas, Padang. Penelitian menggunakan metode glass jar (Kontak) dengan tiga strain kecoak Jerman (VCRU-WHO, KRS-BDG dan HHB-JKT) dan Bioinsektisida minyak sereh dapur. Rata- rata waktu kematian pada jam ke-6 setelah pemaparan dianalisis probit sehingga didapatkan LC90. Hasil penelitian menunjukan nilai LC90 strain VCRU-WHO 15,20%, strain KRSBDG 22,42% and strain HHB-JKT 19,28% pada jam ke-6 setelah pemaparan
