Disclosed is a novel .delta.-endotoxin, designated CryET29, that exhibits insecticidal activity against siphonapteran insects, including larvae of the cat flea (Ctenocephalides felis), as well as against coleopteran insects, including the southern corn rootworm (Diabrotica undecimpunctata), western corn rootworm (D. virgifera), Colorado potato beetle (Leptinotarsa decemlineata), Japanese beetle (Popillia japonica), and red flour beetle (Tribolium castaneum). Also disclosed are nucleic acid segments encoding CryET29, recombinant vectors, host cells, and transgenic plants comprising a cryET29 DNA segment. Methods for making and using the disclosed protein and nucleic acid segments are disclosed as well as assays and diagnostic kits for detecting cryET29 and CryET29 sequences in vivo and in vitro.

Onthuld wordt een nieuwe delta.-endotoxin, aangewezen CryET29, die insecticideactiviteit tegen siphonapteraninsecten, met inbegrip van larven van de kattenvlo (felis Ctenocephalides), evenals tegen coleopteraninsecten, met inbegrip van het zuidelijke graan rootworm (undecimpunctata Diabrotica), westelijk graan rootworm (virgifera van D.), de aardappelkever van Colorado (decemlineata Leptinotarsa), Japanse kever (japonica Popillia), en rode bloemkever tentoonstelt (Tribolium castaneum). Ook onthuld wordt nucleic zuur segmenteert het coderen CryET29, recombinante vectoren, gastheercellen, en transgenic installaties bestaand uit een segment van DNA cryET29. De methodes om de onthulde eiwit en nucleic zuursegmenten te maken en te gebruiken worden onthuld evenals analyses en kenmerkende uitrustingen voor in vitro het ontdekken van opeenvolgingen cryET29 en CryET29 in vivo en.
