Investigation of midgut's ultrastructure of Notonecta viridis Decourt, 1909 and Notonecta maculata Fab., 1794 (Hemiptera:Notonectidae)

Abstract

A pparently, since insects have so many species and perceived as harmful organisms, it has brought to mind the idea of avoidance of these organisms and fighting with them. Insects which we accept both harmful as well as beneficial even have important functions in maintaining the ecological balance [1]. Insect body is divided into three parts as head, thorax and abdomen. Head segments are completely fused and the boundaries of segments cannot be distinguished in adults [2].In generally, insects get their nutrients by bitingchewing or sucking but internal parasite larvae get their nutrients through the body surface. Types of diet and food types of insects are as follows feeding with various parts of plants (herbivores), feeding with peat moss (saprophytes), feeding with small insects or other animals, feeding with fungi and bacteria, feeding with feces, carrion and blood, and those feeding with the filtrate.

Investigation of the midgut structure and ultrastructure in Cimex lectularius and Cimex pipistrelli (Hemiptera: Cimicidae)

“…Therefore, it can be differentiated in some distinct regions with numerous caeca (Rost-Roszkowska 2008). In the majority of Hemiptera that have various feeding strategies, including hematophagous ones, the midgut is divided into three regions—the anterior, middle, and posterior midgut (Silva & Terra 1994, Silva et al 1995, Guedes et al 2007, Habibi et al 2008, Azevedo et al 2009, Bandani et al 2010, Megiud et al 2013, Suicmez & Ozmen 2014). The hemipteran midgut has also been described as having four (Nava-Gervasio et al 2007) or two regions (Jarial 2005).…”
