RNA int.rference （RNAi） of vit.l insect.genes is a pot.nt.al t.ol for t.rget.d pest.cont.ol. However, select.on of t.e right.t.rget.genes is a challenge because t.e RNAi efficacy is known t. vary am.ng insect.species.

It.is shown t.at.for t.icker sheet.m.t.l, it.is recom.ended using large spherical t.ols （12.7 m. or larger）, or a large fiat.ended t.ol. t.e fiat.ended t.ol provides t.e best.com.inat.on of good form.bilit. and very low surface roughness. For alum.num. galvanized st.el and st.inless st.el, it.is recom.ended using a fiat.ended t.ol.
