Disclosed are a nucleotide sequence and a method for controlling insect invasions, the isolated polynucleotide sequence comprising: (a) a polynucleotide sequence as shown in SEQ ID NO: 1, 2 or 3; or (b) a polynucleotide sequence hybridizing with the polynucleotide sequence defined in (a) under stringent conditions; or (c) a polynucleotide sequence having an identity of not less than 80% to the polynucleotide sequence defined in (a); or (d) a polynucleotide sequence of at least 19 consecutive nucleotides of the polynucleotide sequence defined in (a), wherein a double-stranded RNA comprising at least one strand complementary to the polynucleotide sequence, when ingested by an insect pest from Hemiptera, inhibits growth of the insect pest; or (e) a complementary sequence of the polynucleotide sequence as defined in (a), (b), (c) or (d). The three target sequences for controlling an insect pest from Hemiptera, Lygus, have the advantages of efficiency, specificity, convenience and low cost.
公开了一种用于控制昆虫入侵的核苷酸序列和方法,该分离的多核苷酸序列包括:(a) SEQ ID NO:1、2 或 3 中所示的多核苷酸序列;或 (b) 在严格条件下与(a)中定义的多核苷酸序列杂交的多核苷酸序列;或 (c) 与(a)中定义的多核苷酸序列的同一性不低于 80%的多核苷酸序列;或(d)(a)中定义的多核苷酸序列的至少19个连续核苷酸的多核苷酸序列,其中包含至少一条与该多核苷酸序列互补的链的双链RNA,当被半翅目害虫摄食时,可抑制该害虫的生长;或(e)(a)、(b)、(c)或(d)中定义的多核苷酸序列的互补序列。这三种用于控制半翅目害虫蝇蛆的靶序列具有高效、特异、方便和成本低的优点。
