“…This result is consistent with the increase in the calcium content in Hermetia illucens larvae fed with sh feed, up to 2.3 times the initial concentration of young larvae, reported by Proc et al(2020b), and it is also similar to the results obtained in larvae fed with co-products (dried sugar beet pulp), up to 2.7 times the initial calcium concentration, highlighted by Tschirner and Simon (2015). Previous studies with other y larvae (Musca autumnalis) have revealed that large amounts of Ca are ingested and stored in the Malpighian tubules during the larval stage, to subsequently be used during the pupariation process (Darlington et al 1983;Grodowitz and Broce 1983). This calcium uptake by y larvae depends on the concentration of this element in the diet (Dube et al 2000).…”

Bioconversion by Hermetia illucens larvae is a novel technology for organic waste treatment and valorization. However, since the possible uses of products from this process are in agriculture and livestock, the bioconversion must guarantee the mineral quality of both the Hermetia illucens larvae frass and larval biomass. Therefore, this study aimed to assess the mineral content changes for both the larval biomass and larvae frass of Hermetia illucens after the manure bioconversion to determine their suitability as animal feed and organic fertilizer, respectively. Hermetia illucens larvae were put into a plastic box containing fresh cattle manure, and the control treatment with the same conditions without larvae was established. After the first pre-pupae were detected, frass and larvae were collected, and their mineral content was analyzed. At the end of the experiment, the larvae showed increases in some micro and macronutrients, especially calcium and manganese, increasing up to 2.6 and 22.6 times the initial concentration, respectively. The toxic elements concentration was increased in larval biomass, but these levels met the international legislation for animal feed. As a result, the mineral content in larval biomass revealed that Hermetia illucens could be potentially used as animal feed, which could be comparable with fish meal, and is probably better than soybean meal. However, the larvae frass could only be used as organic fertilizer in a Canadian context, with further treatment for decreasing the chromium content being necessary.

“…Multiple mechanisms for HC03-eMux may be important not only in pH regulation but also for specific utilization of HC03-. Examples of this are the silk gland secretion of KHC03 for cocoonase buffering (Kafatos, 1976) and Ca(HCO&, used for puparium development (Darlington et al, 1983). It is reasonable to speculate that the specific tissues involved in these processes might utilize ion transport similar to those found in the CHE cells.…”

The monovalent ion transport systems of an immortalized insect cell line (CHE) have been investigated. These cells are unusual in that unlike most vertebrate cells, their normal extracellular environment consists of high potassium and low sodium concentrations. CHE cells maintained high intracellular [K+] through both a furosemide-inhibitable and a vanadate-inhibitable transport system. Intracellular exchangeable [Na+] was slightly lower than the extracellular [Na+] and was maintained at this level through a vanadate-sensitive transport system. Na+ uptake was also inhibited by furosemide: however, the stoichiometry of furosemide-sensitive Na+ uptake when compared with furosemide-sensitive K+ uptake indicated that these cations are not cotransported. 4,4'-Diisothiocyano-2,2'-disulfonic acid stilbene (DIDS) inhibited Na+, K+, and Cl- uptake. Vanadate and furosemide decreased cytoplasmimic pH, while cytoplasmic pH increased in the presence of DIDS. A model is presented explaining how Na+, K+, Cl-, H+ and HCO3-fluxes are regulated in these cells.

“…Ca and Zn were previously determined in arthropod cuticles in the form of alkaline earth metals (Ca) and transition metals (Zn) and related to an increase in E and H by cross-linking of the chitin fibres [33,[61][62][63][64][65][66][67][68][69][70]. Si was previously also determined in insect cuticle, also in connection with S, Cl, K or Na [60,61,63,69,[71][72][73][74][75][76][77][78][79][80][81]. However, EDX does not enable testing of the atomic bounds.…”

Cimicidae are well-known for traumatic insemination, and males pierce females with their parameres and transfer sperm through them. The shape of parameres is relatively stable in the family, but in some genera, the paramere is elongated, appearing less resistant against lateral deflection. To understand the mechanical limitations of the paramere, we studied its penetration mechanics of the common bed bug, Cimex lectularius . We examined the post-abdominal morphology, paramere geometry and material properties and conducted breaking stress experiments on the paramere under wet and dry conditions. Mechanical property gradients are present with the paramere tip as the stiffest region and the base as the most flexible one. These mechanical properties relate to the presence of Ca, Zn and Si. The basal wing-shaped structure is flexible, enabling it to interlock with the anal region during mating. The paramere is slightly twisted; the tip region is circular in cross-section, and the geometry of the rest is rather complex. In the mechanical tests, wet parameres mainly buckled, while dried parameres broke off. The level of structural failures depended on directions from which the compression forces were applied. Structural, material and mechanical strengthening mechanisms preventing the paramere from mechanical failure are discussed.
