Article Synopsis
- Scarabaeoidea and Chrysomeloidea are harmful insect pests affecting agriculture, and there's limited effective control through Bt insecticidal proteins.
- The study identified a Bt strain, BtSU4, which contains two new genes producing a 135 kDa protoxin that forms irregular crystals, showing activity against various coleopteran species.
- Bioassay results indicate that Cry8Ha1 protoxin is toxic to both larval and adult stages of certain pests, while activation by chymotrypsin changes its toxicity pattern, making it a more effective option for targeting specific coleopteran insects.
