RNAi primer group, recombinant expression vector, transformant, kit and method for regulating and controlling Frankliniella occidentalis

The invention discloses an RNAi primer group, a recombinant expression vector, a transformant, a kit and a method for regulating and controlling Frankliniella occidentalis, and belongs to the field of molecular biology. The RNAi primer group is selected from one pair, two pairs or three pairs of the following primer pairs: a FoTRE1-1 primer pair of which the upstream and downstream primer sequences are respectively shown as SEQ ID NO.1 and SEQ ID NO.2; the upstream primer sequence and the downstream primer sequence of the FoTRE1-2 primer pair are respectively as shown in SEQ ID NO.3 and SEQ ID NO.4; the upstream primer sequence and the downstream primer sequence of the FoTRE2 primer pair are shown as SEQ ID NO.5 and SEQ ID NO.6 respectively. After a recombinant expression vector formed by amplification products of the three primer pairs of the primer group is transferred into a target plant, the egg laying rate and the hatching rate of the Frankliniella occidentalis eating the target plant can be remarkably r
