The subject invention relates in part to the discovery that BtBooster (BtB) peptides enhance Bt strain and Cry protein toxicity to the lesser mealworm. The subject invention also relates in part to the discovery that Bt tenebrionis producing Cry3Aa crystals and Bt japonensis BuiBui producing Cry8Ca crystals are insecticidal to A. diperinus larvae (darkling beetle or lesser mealworm). The subject invention also relates in part to the discovery that fragments from cadherins of the western corn rootworm and the yellow mealworm enhance the toxicities of Bt tenebrionis and Bt japonensis BuiBui toxicity to coleopteran larvae of the genus Alphitobius. In addition, the subject invention relates in part to the use of cadherin fragments to enhance the toxicities of Cry3Aa, Cry3Bb and Cry8Ca to coleopteran larvae of the genus Alphitobius. The subject invention also relates in part to screening Bt strains and Cry proteins for toxicity to larvae of darkling beetles or lesser mealworm, Alphitobius diaperinus.
