“…The morphology of the testicles described in the present study is consistent with the observations made by other authors in Diptera (Amabis, Reinach, & Andrews, ; Lum, ; Valdez, ; Wensler & Rempel, ). This is the first histological record that evidences the presence of testicles in development in the fourth larval stage in chironomids.…”

Chironomids have been widely used in environmental monitoring and toxicity assays. Assessment criteria for chironomids range from the molecular‐biochemical level to the population level. However, the use of markers to evaluate cellular and anatomical changes in organs and systems of individuals under contaminant exposure is still incipient. In this study, we conducted a histological description of the main systems and organs of immature Chironomus columbiensis. We used fourth instar larvae, obtained from a standardized culture, and confirmed this state through morphological and molecular methods. Larvae were fixed in Duboscq solution for insects during 48 hr, dehydrated in increasing dilutions of ethanol, and embedded and mounted in historesin to obtain 3 μm sections. The digestive, nervous, excretory, and integumentary systems and the fat body and testicles were analyzed through longitudinal and transversal sections, stained with hematoxylin–eosin (HE), and further photographed and described through light microscopy. This is the first description of internal morphology performed for C. columbiensis and can help in future histopathological analysis, because through bioaccumulation some of these organs are contaminant targets. It can even be a great taxonomic tool, since the characteristics of the histological pattern of C. columbiensis presented differences compared to other descriptions made in chironomids.

“…As in other anophelines, An.cu1icifacie.y appeared to have two discrete types of secretion in their accessory glands (Lum, 1961;Mahmood & Reisen, 1982). The anterior portion of the glands had large yellow-coloured granular secretions, whereas the smaller posterior portion had opaque small white granules.…”

Under controlled laboratory conditions of 28-30 degrees C and 16:8 L:D photoperiod, an attempt was made to develop an age-grading technique for Anopheles culicifacies males. Mating activity was maximal when females were 5-12 days old males were 5-7 days old. The numbers of total and mature spermatocysts declined significantly with age, and the proportion of the testes occupied by the sperm reservoir increased as virgin males grew older. Mating resulted in the loss of spermatozoa and accessory gland substance from the reproductive system. Loss of mating ability of older virgin males seemed to be age-related, because the reproductive system contained ample supplies of accessory gland substance and spermatozoa. Morphological changes of the reproductive system, due to mating and age, were used to infer the age and reproductive history of unknown males in a laboratory evaluation.

“…113 The role of the plug in reproduction has been controversial for decades and various hypotheses ranged from a physical barrier against reinsemination or sperm loss to a vestigial trait with no function. 31,[114][115][116] Recently, it has been shown that in…”
