dc.description.abstractLeptocorisa oratorius (Hemiptera: Alydidae) is a pest potensial that at certain times become an important pest . This study aimed to test the ability of several concentrations of entomopathogenic fungi B. bassiana Vuillemin Riau local to get a good concentration to control paddy bug pests Leptocorisa oratorius F. This research was conducted at the Center of Agricultural Development and Plant Pests Laboratory, Agriculture Faculty, University of Riau from September 2012 to February 2013. This research has been carried out by using a completely randomized design (CRD), with 8 treatments and 4 replications, in order to obtain 32 experimental units. Each experimental unit consist of 10 imago paddy bug pest, i.e. 0 g/l aquades, 10 g/l aquades, 15 g/l aquades, 20 g/l aquades, 25 g/l aquades, 30 g/l aquades, 35 g/l aquades and 40 g/l aquades. Data were analyzed statistically by analysis of variance and further test with 5 % level of Duncan’s New Multiple Range Test (DNMRT). The parameters observed during the initial test imago death (hours), lethal time 50 (hours), percentage of total mortality (%), temperature and humidity as supporting observations. The results showed local entomopathogenic fungi Beauveria bassiana at a concentration of 35 g/l aquades with a density of 7.98 x 107 conidia/ml is better at controlling paddy bug pest Leptocorisa oratorius F, because cause total mortality of 97.5 % for 12 days (297 hours), the early death of during 13.50 hours and lethal time 50 during 144 hoursen_US
