“…Two species of edible saturniids were selected for distribution modeling, i.e., B. alcinoe and C. forda, because of their popularity and economic importance in sub-Saharan Africa (SSA). Cirina forda and B. alcinoe are widely consumed [11,17,[49][50][51] and traded [16,[52][53][54]] in western, central, eastern, and southern Africa.…”

The promotion of edible insects, including saturniid caterpillars as potential food source is widely gaining momentum. They are adequately rich in nutrients such as proteins, amino acids, fatty acids, and micronutrients. Despite saturniids being a traditional food source with economic benefits, information on their diversity, host plants and their potential distribution in Africa are lacking, which this study seeks to address. Edible saturniids and their host plants were characterized using specific primers (LepF1/LepR1 and 3F_KIM_F/1R_KIM_R, respectively). Maximum entropy (MaxENT) and GARP (genetic algorithm for ruleset production) models were used to characterize the potential distribution of commonly consumed saturniids under current and future climate scenarios. Seven species of saturniids were recorded from 11 host plants in Kenya: Gonimbrasia zambesina, Gonimbrasia krucki, Bunaea alcinoe, Gonimbrasia cocaulti, Gonimbrasia belina, Gynanisa nigra and Cirina forda. Two morphotypes of G. zambesina and B. alcinoe were recorded. These saturniid caterpillars occur twice a year except for G. cocaulti. Predictive models revealed that tropical and subtropical regions were potentially suitable for B. alcinoe and C. forda. The information generated from this study would be important to guide conservation efforts and their sustainable utilization as food in Africa.

“…There are over 130 edible caterpillar species consumed in Africa alone, compared to nearly 400 species worldwide [ 112 ]. Despite their enormous contribution to global food security, little is known about their ecological relevance [ 113 ], associated microbiota, and antimicrobial potential. Caterpillars, unlike other living organisms, do not have a gut microbiota, demonstrating their freedom from symbionts [ 114 ].…”

The need for easily biodegradable and less toxic chemicals in drug development and pest control continues to fuel the exploration and discovery of new natural molecules. Like certain plants, some insects can also respond rapidly to microbial infections by producing a plethora of immune-induced molecules that include antibacterial and antifungal peptides/polypeptides (AMPs), among other structurally diverse small molecules. The recent recognition that new natural product-derived scaffolds are urgently needed to tackle life-threatening pathogenic infections has been prompted by the health threats posed by multidrug resistance. Although many researchers have concentrated on the discovery of AMPs, surprisingly, edible insect-produced AMPs/small molecules have received little attention. This review will discuss the recent advances in the identification and bioactivity analysis of insect AMPs, with a focus on small molecules associated with the microbiota of selected African edible insects. These molecules could be used as templates for developing next-generation drugs to combat multidrug-resistant pathogens.

“…Moreover, G. africana, N. septemfasciata, L. migratoria and C. forda are noticed by whistling and canals in the wet ground. (Ngute et al, 2020). Also, it should be noted that most of the hosts are plants used as a source of food and revenue; for example, the plant B. toxisperma is a class A timber species, which produces fruits with a highly valued and edible oil is extracted (Meunier et al, 2015).…”

In response to growing food demand, edible insects are seen as a potential source to alleviate food insecurity. With its wide edible insects’ biodiversity, the Democratic Republic of Congo is one of the most important biodiversity hotspots in Africa. This study aimed at giving a first insight on the inventory showing diversity, perception, consumption, availability, host plants, harvesting techniques and processing techniques of edible insects in South-Kivu, DRC. It recorded twenty-three edible insects belonging to nine families and five orders, some of which are consumed in the larval, adult, egg and pupa stages. Rhyncophorus phoenicis, Alphitobius diaperinus, Macrotermes subhylanus and Acheta domesticus were the most preferred edible insects in Fizi Territory, Ruspolia differens and Apis melifera larvae in Kabare Territory, Imbrasia oyemensis, Imbrasia epimethea, Rhynchophorus ferrugineus and Rhyncophorus phoenicis in Mwenga Territory, Ruspolia differens, Macrotermes subhylanus, Gryllotalpa africana, Nsike, Nomadacris septemfasciata and Apis melifera larvae in Walungu Territory. R. differens, I. oyemensis, A. melifera larvae, G. africana and Nsike were preferred for their taste. A. domesticus, A. diaperinus and A. melifera larvae were abundant throughout the year, while the others were only available for 9 months or less per year. Numerous plants have been recorded as their hosts, including plants used for food and income. Harvesting strategies and period, processing methods and preservation techniques depend on insect species, local knowledge and practices. These findings suggest similar and thoroughly studies on entomophagy across the country, while encouraging the rearing of edible insects to address the high existing demand and environmental need.
