A modified bilateral in utero electroporation technique allows for the gene transfer in large populations of neurons and examination of the causative effects of gene expression changes on social behavior.

Biology RNAi Trigger Delivery into Anopheles gambiae Pupae Kimberly Regna1, Rachel M. Harrison1, Shannon A. Heyse1, Thomas C. Chiles1, Kristin Michel2, Marc A. T. Muskavitch1,3 1Biology Department, Boston College, 2Division of Biology, Kansas State University, 3Discovery Research, Biogen RNA interference (RNAi) is an extremely valuable tool for uncovering gene function. However, the ability to target genes using RNAi during pre-adult stages is limited in the major human malaria vector Anopheles gambiae. We describe an RNAi protocol to reduce gene function via direct injection during pupal development.
