Classification of bioagent

The bioagents can be classified as;

1. Obligate bioagents:

• Associated with a specific insect or disease host and are difficult to culture artificially.
• Eg; Bacillus popilliae causing milky disease of white grubs.

2. Spore forming bioagents:

• The protein crystals formed by these sporulating inoculants are toxic to target pests.
• Eg; Bacillus cereus produce such toxins.

3. Determinative bioagents:

• They get activated inside host and multiply in haemocoele of insect producing lethal septicemia.

4. Facultative bioagents:

• The host tissue is damaged by the invasion of the bioagents but they are not obligate parasites.
