      Abstract
      Penelitian dilakukan untuk mengetahui kejadian penyakit cendawan entomopatogen pada Spodoptera exigua (Lepidoptera: Noctuidae) dalam jaring tritrofik pada tanaman bawang daun. Populasi S. exigua dan infeksi cendawan entomopatogen pada S. exigua dilakukan dengan pengamatan langsung. Identifikasi cendawan terisolasi menginfeksi S. exigua dilakukan di laboratorium. Populasi S. exigua pada ketiga perlakuan, yaitu monokulktur bawang daun, monokultur bawang daun disemprot dengan ekstrak daun wortel, dan tumpang sari bawang daun dengan wortel tidak berbeda nyata. Kejadian penyakit yang disebabkan oleh Nomuraea sp. relatif rendah karena populasi S. exigua yang rendah. Kejadian penyakit Nomuraea sp. pada ketiga perlakuan, yaitu monokulktur bawang daun, monokultur bawang daun disemprot dengan ekstrak daun wortel, dan tumpang sari bawang daun dengan wortel tidak menunjukkan peberbedaan yang nyata
       
      The study was conducted to determine the incidence of entomopathogenic fungus on Spodoptera exigua (Lepidoptera: Noctuidae) in net tritrophic on green onion. Population of S. exigua and fungal infection of S. exigua was recorded by direct observation. Identification of isolated fungus infecting S. exigua was carried out in the laboratory. Populations of S. exigua on three different treatments, green onion, green onion sprayed with carrot leaf extract and green onion intercropped with carrot, were not significantly different. Incidence of disease caused by Nomuraea sp. was relatively low due to the low population of S. exigua. Incidence of disease caused by Nomuraea sp. on three different treatments, green onion, green onion sprayed with carrot leaf extract and green onion intercropped with carrot, was not significantly different
