Edible insects are a healthy, sustainable, and environmentally friendly protein alternative. Thanks to their quantitative and qualitative protein composition, they can contribute to food security, especially in Africa, where insects have been consumed for centuries. Most insects are still harvested in the wild and used for household consumption. So far, however, little attention has been paid to insects’ real contribution to food security in low-income countries. Entomophagy, the human consumption of insects, is widespread in many rural areas of Madagascar, a country, at the same time, severely affected by chronic malnutrition. This case study was carried out in a region where entomophagy based on wild harvesting is a common practice and malnutrition is pervasive. The data were obtained in 2020 from a survey among 216 households in the rural commune of Sandrandahy in the central highlands of Madagascar. Descriptive statistics, correlation, and regression analysis were used to show the relative importance of insects for the local diet and to test various hypotheses related to food security. Results show that insects contribute significantly to animal protein consumption, especially in the humid season, when other protein sources are scarce. They are a cheap protein source, as much esteemed as meat by the rural population. There are no significant differences in the quantities of insects consumed by poorer versus richer households, nor between rural and urban households. Insect consumption amounts are strongly related to the time spent on wild harvesting. The importance of edible insects for poor, food-insecure rural areas and how entomophagy can be promoted for better food and nutrition security are discussed.

In the current times of climate change, the intense use of insects as a protein source is gaining popularity worldwide, and will likely contribute to increased nutrient intake in food and feed due to its nutritional, ecological, nutraceutical, and medicinal potential. Ancient traditional consumption of wild-harvested insects in Africa is a valuable but diminishing resource. There is a need for improved technology in insect rearing to match production with the current population pressure since we can no longer depend on wild collection. The current legislation within the European Union opens a pathway towards acceptance, increased consumption, and marketing of edible insects, which already had a big role in African nutrition as a portion of seasonal food. Food security and expensive animal protein sources are a setback in Africa and there is a need to search for alternative sources to curb malnutrition. Insect use in animal feed is gaining momentum in pig, fish, pet, and poultry feed. To meet the rising demand for insect protein in animal feed, it calls for new ways to increase availability while addressing food quality, safety, and environmental sustainability. Apart from their importance as a source of nutrients, insects help to recycle organic waste, and the remaining portion can be used in plant protection and as a soil modifier. This review, therefore, undertakes exploration and outlook on the ancient utilisation of edible insects in Africa, current efforts to improve through farming, and the challenges faced with the hope that traditional practices will shape the future of the edible insect industry.

“…Cirina forda, a Lepidoptera of the family Saturniidae, is univoltine and experiences th obligatory summer diapause in which the 5 instar larva digs, pupates, and remains inactive in the soil for 9 to 10 months (Oriolowo et al, 2023). This phenomenon is common to other related Cirina https://dx.doi.org/10.4314/ijs.v25i1.2 species (Bama et al, 2018;Payne et al, 2019). The pupa remains in this state until favourable conditions of humidity, food, and temperature.…”

Diapause is a complex life history strategy aimed at tolerating or circumventing stress in insects. It is accompanied by alterations in the food reserve levels to cope with the energy demand of this life stage. In the pallid emperor moth (Cirina forda), little is known about the patterns of accumulation and utilization of food reserves before and during diapause, respectively. The accumulation and utilization of food reserves in the haemolymph and the whole body of diapause-destined larvae and diapausing pupae of Cirina forda were progressively compared using photometry and HPLC. The quantity of glucose, total carbohydrate, fats, protein, and amino acids measured were taken as indices of food reserve accumulation and utilization by the immature stages of the insect in this study. Data collated were analyzed using Analysis of Variance (ANOVA), and the means were separated using Fisher's Least Significance Difference (LSD). The results showed progressive accumulation of glucose from 46.20 to 105.06 mg/100 g, total carbohydrates from 175.39 to 212.54 mg/100 g, lipids from 440.49 to 641.57 mg/100 g, and protein from 306.04 to 378.83 mg/100 g in the haemolymph of diapause-destined larvae. The reserves decreased progressively (72.1%, 60.3%, 5.7%, and 6.9%) in diapausing pupae. Total amino acids increased by 2.8%, while 61.1% of amino acids in the whole pupae increased significantly (P<0.05). The study concluded that C. forda accumulates food reserves in preparation for diapause, and reserves decline as they are probably utilized during diapause development.
