“…Pendant les stades prtchrysalide (Yeager 1945;Arnold 1952;Clark et Chadbourne 1960) et chrysalide (Wittig 1968), il y a habituellement une baisse significative de leur nombre suivie d'une nouvelle stabilisation chez l'adulte (Yeager 1945;Arnold 1952). Gtntralement, ces cellules se maintiennent un niveau numerique habituellement tleve jusqu'au dernier stade larvaire ou a la chrysalide.…”

Five types of hemocytes were identified: prohemocytes, plasmatocytes, granular hemocytes, spherule cells, and oenocytoids. The low numbers of prohemocytes and oenocytoids, the significant decrease in the number of plasmatocytes in last larval stages, and the corresponding increase in granular and spherule cells have been compared with existent literature. Total hemocyte counts were also made.

“…Spherulocytes undertake the secretion of cuticular components (peptides), although their role remains somewhat enigmatic. Granulocytes prove instrumental in encapsulation and indirectly contribute to phagocytosis [ 172 , 174 , 175 , 176 , 177 ].…”

“…Intriguingly, the interconnected nature of G. mellonella's cellular and humoral immune systems is evident. Hemocytes assume responsibility for the production of humoral molecules, and their activation by these molecules underscores the model's significance as an intermediary in vivo system, bridging the gap between in vitro assays and mammalian investigations [168,172]. The wax worm possesses anatomical and physiological barriers fortifying it against the external environment.…”

In the study of fungal pathogenesis, alternative methods have gained prominence due to recent global legislation restricting the use of mammalian animals in research. The principle of the 3 Rs (replacement, reduction, and refinement) is integrated into regulations and guidelines governing animal experimentation in nearly all countries. This principle advocates substituting vertebrate animals with other invertebrate organisms, embryos, microorganisms, or cell cultures. This review addresses host–fungus interactions by employing three-dimensional (3D) cultures, which offer more faithful replication of the in vivo environment, and by utilizing alternative animal models to replace traditional mammals. Among these alternative models, species like Caenorhabditis elegans and Danio rerio share approximately 75% of their genes with humans. Furthermore, models such as Galleria mellonella and Tenebrio molitor demonstrate similarities in their innate immune systems as well as anatomical and physiological barriers, resembling those found in mammalian organisms.
