Cryptonephridic complex

Weboccurrence of the cryptonephric condition in insects has recently been written by Saini (i962). The present work is concerned only with the cryptonephric condition as it exists in the larva and adult of the mealworm, Tenebrio molitor L. The structure of the rectal complex has been worked out in considerable detail, as will WebInsect diuretic hormones are hormones that regulate water balance through diuretic action.. The insect excretory system, responsible for regulating water balance in the insect, comprises the Malpighian tubules and the hindgut (the ileum and rectum).Malpighian tubules secrete primary urine, most of which is passed into the hindgut where water, ions …

Webknown as ‘cryptonephric complex’. This system facilitates the reabsorption of water and, therefore, is more highly developed in insects that feed on dry substances or live in a relatively dry environment and therefore need to retain water [4,7].
