    • This invention pertains to recombinant baculoviruses that have been engineered to afford optimal expression of genes encoding insect-selective neurotoxins. More specifically, this invention pertains to an isolated nucleic acid sequence encoding the scorpion toxin LqhIT2, derived from Leiurus quinquestriatus hebraeus, wherein said sequence has been optimized for gene expression in nuclear polyhedrosis virus-infected cells. This invention also pertains to chimeric genes comprising a codon-optimized LqhIT2 nucleotide sequence, insecticidal compositions comprising recombinant baculoviruses expressin a codon-optimized, insect-selective neurotoxin (e.g., the LqhIT2 toxin gene), and methods for controlling insects in both agronomic and non-agronomic environments comprising application of insect baculoviruses containing the codon-optimized nucleic acid sequence encoding an insect-selective neurotoxin such as the LqhIT2 toxin.
    • 本发明涉及已被改造以提供编码昆虫选择性神经毒素的基因的最佳表达的重组杆状病毒。 更具体地说,本发明涉及编码源自雷欧曲霉(Leiurus quinquestriatus hebraeus)的蝎毒素LqhIT2的分离的核酸序列,其中所述序列已被优化用于在核型多角体病毒感染的细胞中的基因表达。 本发明还涉及包含密码子优化的LqhIT2核苷酸序列的嵌合基因,包含密码子优化的昆虫选择性神经毒素(例如,LqhIT2毒素基因)表达的重组杆状病毒的杀虫组合物,以及用于在农艺和非农业中控制昆虫的方法 所述方法包括应用含有编码昆虫选择性神经毒素如LqhIT2毒素的密码子优化的核酸序列的昆虫杆状病毒。
