Abstract :
Biopesticide from Beauveria bassiana which were isolated from soil were obtained by using
local materials. According to the number of spores/g of each material, two formulas were chosen.
Formula A consist of 300 g (B. bassiana) grown on rice seeds + 400 g CaCO3 + 100 of hornwort + 200 g
of kaolinite. Formula B consist of 300 g (B. bassiana) grown on millet seeds + 400 g CaCO3 + 100 g
hornwort + 200 g kaolinite. Field experiment reveled that biopesticide formulated from B. bassiana was
effective in control date palm stem borer but formula (B) which consisted mainly from B. bassiana grown
on millet seeds was the best in control date palm stem borer larva as mortality percentage reached 72.7 %
compared with 60 % of formula A.
