Abstract:

RNA interference technology has been widely used for investigating functions of genes for more than 20 years since its inception. In Hymenoptera, parasitoid wasps are a group of important natural enemy against pests in agriculture and forestry. The inhibition of target gene expression relies on the delivery of dsRNA. However, the parasitoids develop on host insects, and interact with their hosts. This biological characteristic makes it challenging to conduct RNAi technology. The RNAi technology has already been conducted in the studies involved the molecular mechanisms of at least 13 species of parasitoid wasps, e.g. Nasonia vitripennis, Microplitis mediator, Cotesia vestalis, Pteromalus puparum, and Meteorus pulchbernis. This study reviewed the studies of the molecular mechanisms by using RNAi method, and summarized the factors influencing RNAi efficiency in parasitoid wasps, aiming to provide the reference for application of RNAi technology in parasitoid wasps.

Key words: parasitoid wasps, RNA interference, molecular mechanism, RNAi efficiency
