Fig. 2From: Establishment of molecular genetic approaches to study gene expression and function in an invasive hemipteran, Halyomorpha halys Severe defects in unhatched offspring after Scr RNAi. Photographs of nymphs dissected out of egg cases are shown. a Control, gfp pRNAi is fully developed with proboscis (red dashed line). Note that wild-type animals darken after they hatch. b, c Different examples of Hh-Scr pRNAi offspring with severely malformed or absent head structures (yellow dashed lines). These Hh-Scr pRNAi embryos were presumably unable to hatch and therefore were still within the egg shell as they matured and darkenedBack to article page
