    Abstract: The subject invention concerns Bacillus thuringiensis microbes with activity against select coleopteran pests, e.g., Diabrotica sp., Hypera sp., and various flea beetles. For example, the B.t. isolates of the invention are active against alfalfa weevils (AW, Hypera brunneipennis), rape flea beetles (RFB, Phyllotreta cruciferae), and corn rootworms (CRW, Diabrotica undecimpunctata undecimpunctata). Thus, these microbes can be used to control these pests. Further, genes encoding toxins active against these pests can be isolated from the B.t. isolates and used to transform other microbes. The transformed microbes then can be used to control susceptible coleopteran pests. In preferred embodiments, a gene from PS140E2 is used to transform plants so that the transformed plants are resistant to flea beetles of the genus Phyllotreta.

    Abstract translation: 本发明涉及具有针对选择性鞘翅目害虫的活性的苏云金芽孢杆菌微生物,例如Diabrotica sp。,Hypera sp。和各种跳蚤甲虫。 例如,B.t. 本发明的分离株对苜蓿象鼻虫(AW,Hypera brunneipennis),强奸跳蚤(RFB,十字花科植物)和玉米根虫(CRW,Diabrotica undecimpunctata undecimpunctata)具有活性。 因此,这些微生物可用于控制这些害虫。 此外,编码对这些害虫有活性的毒素的基因可以从B.t. 分离并用于转化其他微生物。 然后转化的微生物可用于控制易感的鞘翅目害虫。 在优选的实施方案中,使用来自PS140E2的基因来转化植物,使得转化的植物对Phyllotreta属的跳蚤甲虫具有抗性。
