Control of two sucking insect pests, a whitefly (Bemisia tabaci) and a thrips (Frankliniella occidentalis), infesting hot peppers by spraying LDH-formulated dsRNA.

ABSTRACT:

Background

Whiteflies and thrips are serious pests by feeding on plant tissues and transmitting plant viruses to crops. To avoid excessive uses of chemical insecticides, spraying double-stranded RNA (dsRNA) has been proposed as an alternative control measure against these sucking insect pests. However, it is not clear how best to effectively deliver dsRNA to the sucking insects.

Results

A potent dsRNA was generated against a vacuolar type ATPase subunit B (vATPase-B) gene of the silverleaf whitefly, Bemisia tabaci, which shares a high sequence homology (85.7%) with that of the western flower thrips, Frankliniella occidentalis. The gene was well expressed in the intestine of the whitefly at the nymph and adult stages, in which it was highly expressed at the filter chamber and
