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

/70ml water, suspension  B. bassiana with
conydia density 10

/70 ml water, suspension B. bassiana with conydia density 10
/70 ml water,
suspension B. bassiana  with conydia density 10

/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

/70 ml water) with 20.77 gr/polibeg/6
crop.
