Uji Efektifitas Jamur Entomopatogen Beauveria bassiana dan Metarhizium anisopliae terhadap Kepik Hijau (Nezara viridula L.) (Hemiptera ; Pentatomidae) pada Tanaman Kedelai (Glycine max L.) di Rumah Kasa

Abstract

The objective of the research was study of  the effectivity test  of  fungi entomopathogen   Beauveria  bassiana  and  Metarhizium anisopliae on different conydia densities to infect the rodent adult green stink bug  (Nezara viridula L.) This research was conducted at the screen house Faculty of Agriculture, University of North Sumatra, from Desember 2013 until Mei 2014. This research using Randomized Block Design non factorial with 7 treatments (control, suspension  M. anisopliae with conydia density 10 7 /70 ml water, suspension M. anisopliae with conydia density 10 /70 ml water, suspension M. anisopliae with conydia density 10 9 /70ml water, suspension  B. bassiana with conydia density 10 7 /70 ml water, suspension B. bassiana with conydia density 10 /70 ml water, suspension B. bassiana  with conydia density 10 9 /70 ml water) with three replications. The results showed that fungi entomopathogen B. bassiana and M. anisopliae affected significantly to percentage of mortality, percentage of natalitas, and soy production. The best result for the percentage of mortality was N 3 (suspension  M. anisopliae with conydia density 10 /70 ml water) with 94.44%, The highest percentage of  natalitas was  N with 96.40%, The highest soy production was N 3 (suspension  M. anisopliae with conydia density 10 0 9 /70 ml water) with 20.77 gr/polibeg/6 crop.
