Application of Bta60SRPL7 gene in prevention and treatment of bemisia tabaci, reagent for preventing and treating bemisia tabaci and prevention and treatment method

The invention discloses application of a Bta60SRPL7 gene in bemisia tabaci prevention and control, a bemisia tabaci prevention and control reagent and a bemisia tabaci prevention and control method, and belongs to the technical field of pest prevention and control. The nucleotide sequence of the bemisia tabaci Bta60SRPL7 gene is shown as SEQ ID NO.1, efficient silencing dsBta60SRPL7 is prepared according to the Bta60SRPL7 gene, the dsBta60SRPL7 is introduced into the bemisia tabaci body through a feeding method, and the host positioning capacity and feeding behavior of the bemisia tabaci can be remarkably reduced, so that the prevention and treatment purpose is achieved. The method is convenient to operate, high in effectiveness and specificity and obvious in host selectivity influence effect, has the advantages of environmental friendliness and the like, and has a very good application prospect. 本发明公开了一种Bta60SRPL7基因在烟粉虱防治中的应用、防治烟粉虱的试剂及防治方法，属于虫害防控技术领域。本发明烟粉虱Bta60SRPL7基因的核酸序列如SEQ ID NO.1所示，根据Bta60SRPL7基因制备其高效沉
