Which organisms are specifically controlled by Bacillus popilliae?

• A. Caterpillars
• B. Japanese beetles
• C. Fire ants
• D. Webworms

Answer: (B)

Bacillus popilliae is a bacterium that specifically targets the larvae of Japanese beetles. This pathogen is known for its role in biological control, particularly in managing pest populations without the use of chemical pesticides. When Japanese beetle larvae ingest Bacillus popilliae, the bacteria multiply in their digestive systems, leading to mortality. This method of pest control is environmentally friendly and can reduce the reliance on synthetic insecticides. The other organisms listed do not have a natural susceptibility to this bacterium. Caterpillars, fire ants, and webworms are managed through different biological control agents or chemical methods, but Bacillus popilliae is specifically effective against Japanese beetle larvae, making it a key player in the integrated pest management strategies targeting this particular pest.
