RNAs from different tissues (fat body, midgut, and Malpighian tubules of adults), as well as 1st- and 2nd-instar larvae, were isolated by using RNeasy[R] Plus Micro Kit with Qiageng DNA Eliminator spin column (Qiagen, Hilden, Germany).
The digestive tracts were divided into the foregut, midgut, ileum, rectum, and Malpighian tubules.

Total RNA was isolated from different tissues (fat body, gut, Malpighian tubule and trachea of the third instar larvae), 1- and 4-d larvae, using RNeasy[R] Plus Micro Kit with gDNA Eliminator spin column (Qiagen, Hilden, Germany).
In all cases the appendix tubules are one-third the diameter of the Malpighian tubules and motile: in Euphasmatodea they are coiled like springs, and contract and expand throughout the body cavity (Shelomi & Kimsey 2014).
Associated with the digestive tract, but part of the excretory system, are the Malpighian tubules (Figure 4).
