What category does Bacillus popillae belong to?

Bacillus popillae is a bacterium that is specifically used as a biological insecticide. This bacterium targets and is pathogenic to certain insects, particularly the larvae of the Japanese beetle. As it infects and multiplies in these pests, it effectively helps to reduce their populations, demonstrating the characteristics of an insecticide.

The classification of Bacillus popillae as an insecticide highlights its role in pest management, which focuses on naturally occurring organisms to control pest species without the reliance on synthetic chemicals. This method aligns with integrated pest management practices, aiming for more sustainable and environmentally friendly approaches to control pest populations.

While Bacillus popillae does belong to the broader category of pesticides, identifying it specifically as an insecticide provides a more precise understanding of its application and target, distinguishing it from herbicides, fungicides, or other pesticide categories that do not address insect pests.
