Abstract

The effect rate of Bacillus thuringiensis and Neemazal were studied determination in trial studies making for biological control of Lymantria dispar (L.) damaging in Quercus (Quercus petraea) forests. Caterpillars in the secand-third tunica were put 75 numbers as 15 numbers in every trial pot. Drug prepared by adding 1 cc to 1 liter water from Bacillus thuringiensis var. kurstaki being 16.000 bacterial in mg was sprayed to fresh Quercus leaves. Leaves which were wetted with drug were put in trial pots by drying on 27.05.2012. Death of  58 caterpillars and death of 6 pupaes were determined in controls made on 03-10-25.06.2012. Moreover, 11 grown pupaes was determined. B. Thuringiensis was observed to be effective in rate of %85,3 on larvaes. With drug prepared by adding 1 cc Neemazal to 1 liter water, it was determined that 59 caterpillars were died, 16 pupaes were remained in pupae stage, 2 pupaes were died, 14 pupaes were adult. Furthermore, Neemazal was observed to be effective in rate of %81,3.

Key words: Lymantria dispar, Bacillus thuringiensis, biological control, Neemazal
