Summary Introduction

To review:

The reason that prevented the molting of a Rhodnius when it was decapitated after one hour of feeding, but molting occurred when decapitation was done after one week of feeding.

Introduction:

Rhodnius prolixus is an inch-long arthropod, which is reddish-brown in color. It is commonly called assassin bug and is the vector for a protozoan that causes Chagas disease. Due to the fact that it can survive without a head for a longer time, it is used by the researchers for various experiments.
