20090018074 | Peptides for Inhibiting Insects - The subject invention pertains to the use of peptide fragments of cadherins (including cadherin-like proteins). The subject invention includes a cell (and use thereof) comprising a polynucleotide that expresses the peptide fragment. The subject invention includes methods of feeding the peptides to insects. In preferred embodiments, the peptides are fed to target insects together with one or more insecticidal proteins, preferably (but not limited to) B.t. Cry proteins. When used in this manner, the peptide fragment can not only enhance the apparent toxin activity of the Cry protein against the insect species that was the source of the receptor but also against other insect species. Preferably, the cadherin is a | 01-15-2009 |

20110112012 | Novel Protein for Binding Bacillus Thuringiensis Cry Toxins and Fragments of Cadherins for Enhancing Cry Toxicity Against Dipterans - The subject invention relates in part to a novel protein for binding | 05-12-2011 |
20110183896 | ENHANCEMENT OF BACILLUS THURINGIENSIS CRY PROTEIN TOXICITIES TO COLEOPTERANS, AND NOVEL INSECT CADHERIN FRAGMENTS - The subject invention relates in part to the discovery that a fragment from a cadherin of the western corn rootworm enhances Cry3 toxicity to larvae of naturally susceptible species. The subject invention also relates in part to the discovery that a cadherin fragment from a beetle enhances Cry3Aa and Cry3Bb toxicity to coleopteran larvae, particularly those in the family Chrysomelidae. Such cadherin fragments are referred to as Bt Boosters (BtBs). The subject invention can be extended to the use of BtBs with other coleopteran-toxic Cry proteins for controlling a wide range of coleopterans. | 07-28-2011 |
20110201549 | Enhancement of Bacillus Thuringiensis Cry Toxicities to Lesser Mealworm Alphitobius Diaperinus - 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 | 08-18-2011 |
20120034610 | IDENTIFICATION OF TOXIN-BINDING PROTEIN INVOLVED IN RESISTANCE TO CRY1 TOXINS, AND RELATED SCREENING METHODS - The subject invention relates in part to the surprising and unexpected discovery that insects that are resistant to | 02-09-2012 |
20120220521 | MODIFIED PEPTIDES HAVING TOXIN-ENHANCING EFFECTS - This invention relates in part to modifying BtBooster (BtB) peptides, in part to increase their stability in insect midgut digestive juices. Some preferred embodiments of BtB have removed proteinase cleavage sites resulting in increased stability of the modified BtB in the insect gut, while retaining the ability to enhance B.t. proteins for improved insect control. In some preferred embodiments, the protease-stable BtB is used in combination with B.t. spores and/or crystals comprising a Cry protein. Also reported herein is the significant and increased enhancement of Bt toxins against relatively Bt-tolerant insects ( | 08-30-2012 |
