“Bt”菌剂生物杀虫剂是一种好气性产伴孢晶体的芽孢杆菌,(每毫升含活芽孢一百亿以上),所产生的伴孢晶体是一种蛋白质毒素(也称内毒素),它是使害虫致病死亡的芽孢杆菌。对鳞翅、膜翅目中的20多个科150余种害虫具有专一的毒杀作用。
The “Bt” fungus agent is a bacterium of gas-producing progeny spores (more than 10 billion live spores per milliliter). The produced sporulation is a protein toxin (also known as endotoxin ), Which is a Bacillus that causes the pest to die.
