Abstract
Abstract TWO BIOLOGICAL INSECTICIDES AND METHOD OF PREPARATION THEREOF ARE DISCLOSED. IN THE ONE METHOD POLYHEDRAL INCLUSION BODIES OF THE NUCLEAR PLYHEDROSIS VIRUS OF THE CABBAGE LOOPER, TRICHOPLUSIA NI, WERE PRECIPITATED FROM CONCENTRATED SUSPENSIONS IN 4-6% SOLUTIONS OF LACTOSE UPON ADDITION OF ACETONE. ALTERNATE STEPS TO THE METHOD OF PREPARATION ARE ALSO PROVIDED. A DRY RESUSPENDABLE PRODUCT (IN WATER) IS OBTAINED. IN THE SECOND METHOD, THE SPORE-CRYSTALLINE TOXIN COMPLEX OF BACILLUS THURINGIENSIS WAS PRECIPITATED FROM CONCENTRATES DERIVED FROM FERMENTATION BEERS RESUSPENDED IN 4-6% LACTOSE UPON ADDITION OF ACETONE.
