Promising groups of environmentally-safe insecticides consist of analogues of insect hormones, such as juvenile hormone, and antagonists of such hormones. The traditional bioassay approach for screening potential juvenile hormone analogs and antagonists is slow, expensive and inefficient. A recombinant bHLH-PAS-juvenile hormone receptor, isolated from methoprene-tolerant locus on
Drosophila,
provides the basis of in vitro and in vivo binding assays that can be used to discover new juvenile hormone-type targeted insecticides. Moreover, the nucleotide sequence of the
Drosophila
bHLH-PAS/JHR polypeptide provides tools for isolating juvenile hormone receptor genes from other insect species.
有前景的环境安全杀虫剂包括昆虫激素(如幼虫激素)的类似物和此类激素的拮抗剂。传统的生物测定方法筛选潜在的幼虫激素类似物和拮抗剂的速度慢、成本高、效率低。从果蝇的耐甲氧苄啶基因座中分离出的重组 bHLH-PAS-幼年激素受体,可用于筛选潜在的幼年激素类似物和拮抗剂。
