Some strains of Bacillus thuringiensis produce protein that kill certain Insects such as armyworm. Armyworm is

Options

A. dipteran
B. lepidoptera
C. Coleopteran
D. all of these

Answer

To solve the question regarding the classification of armyworm in relation to Bacillus thuringiensis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: We know that Bacillus thuringiensis (Bt) is a bacterium that produces insecticidal proteins effective against certain insects, including armyworms.

2. **Identify the Options**: The options given are Diapetron, Lapidopetra, Coleopetron, and all of these. We need to determine which of these classifications includes armyworms.

3. **Research Insect Classification**:
- Diapetron is a genus that includes flies and mosquitoes.
- Coleopetron refers to beetles.
- Lapidopetra is a group that includes moths and butterflies, which are known to have species like armyworms.

4. **Narrow Down the Options**: Since armyworms are not flies or beetles, we can eliminate Diapetron and Coleopetron.

5. **Confirm the Correct Group**: Since armyworms belong to the order Lepidoptera, which is included in the group Lapidopetra, we conclude that the correct classification for armyworm is Lapidopetra.

6. **Final Answer**: Therefore, the correct answer to the question is **Lapidopetra**.
