| Sumario: | <p><strong>The effect of <em>Bacillus thuringiensis</em> to the mortality of corn stemborer <em>Ostrinia furnacalis</em> (Lep. Pyralidae).</strong> The study was conducted at the laboratory of Bogor Research Institute for Agricultural Biotechnology and Genetic Resources during 2005. The objective of this study was to evaluate the effect of the dosages of <em>Bacillus</em>. <em>thuringiensis</em> var. aizawai and var. Kurstaki on the mortalities of larvae of corn stemborer <em>Ostrinia furnacalis</em>. Completely randomize design was used with seven treatments. Each treatment was repeated four time with ten larvae per replication. The treatments were three formulation dosages of <em>B. thuringiensis</em> var. aizawai, i.e. 0,5; 1,0; and 2,0 g/l, thee formulation dosages of <em>B. thuringiensis</em> var. Kurstaki, i.e. 0,5; 1,0; and 2,0 g/l, and untreated control. Second instar larvae of <em>O. furnacalis</em> was used in this study. <em>B. thuringiensis</em> was contaminated to the surface of artificial diet with a small paint brush. The result showed that <em>B. thuringiensis</em> var. kurstaki at the dose rate of 1,0 g/l was toxic to the test insect while <em>B. thuringiensis</em> var. aizawai at the dose rate of 2,0 g/l was toxic to the test insect <em>B. thuringiensis</em> var. kurstaki was more toxic than <em>B. thuringiensis</em> var. aizawai to the corn stemborer.</p> |
