title: [New coleopterancidai strains of Bacillus thuringiensis and production of coleopterancide].
abstract: Two coleopterancidal strains of Bacillus thuringiensis, YM-03 and SHQ11-10, were isolated from soil in China. H-Serotype of YM-03 was H8a8b, and H-Serotype of SHQ11-10 has not been identified. Both of them produced flat bipyramid-like crystals which consisted of 68-70 kD and 65 kD protein respectively. Bioassay indicated that these two Bt strains were very active on the larva of Leptinotarsa decemlineata and Plagioder aversicolora. They grew prosperously in fermentation. Powder of YM-03 product was high effect against colorado potato beetle in the field experiment.
