Methods and Results: After chemical analysis by the standard methods (AOAC) in the laboratory, the composition of this… Show more
“…Iron is a trace element essential for the functioning of cells and is a fundamental constituent of red blood cells because it allows the transport of oxygen. The larvae studied have an iron concentration close to that reported by Foua Bi et al (2015) for the larvae of Imbrasia oyemensis. It is higher than the average iron content recommended by l'EFSA (2015) and FAO (2004).…”

“…The iodine value observed for palm larvae (142.83 ± 0.61 mg KOH / g) is higher compared to that of beef (45.5 ± 0.4 g / I2 / 100 g). Apart from beef, the iodine value of these larvae is higher than that of the corn oil grown in Pakistan (Qasim et al, 2013) and flour from Imbrasia oyemensis (Foua Bi et al, 2015). Indeed, the iodine index is an essential trace element that is directly related to the thyroid gland which it ensures the proper functioning.…”
In Côte d'Ivoire, the larvae of the oil palm weevil, Rhynchophorus phoenicis, are appreciated and consumed by rural and urban populations. However, many people are unaware of the nutritional qualities of these larvae. The objective of this study was to compare the nutritional value of these larvae with that of the beef and fish usually consumed. The different nutritional components of late stage larvae, beef and fish were determined from standard analytical methods. Moisture contents of 25.66 ± 0.05; 60.47 ± 0.08 and 39 ± 0.28 mg / 100 g, lipid 39.14 ± 0.01; 12.47 ± 0.05 and 1.26 ± 0.005 mg / 100 and protein of 29.9 ± 0.11; 25.56 ± 0.02 and 22.16 ± 0.15 mg / 100 g were obtained for R. phoenicis, beef and fish, respectively. The ash content was 5.02 ± 0.01; 1.5 ± 0.1 and 0.46 ± 0.57 mg / 100 respectively for R. phoenicis, beef and fish. These three samples are characterised by respective iodine numbers of 161.86 ± 0.1; 142.83 ± 0.2 and 45.5 ± 0.4 I2 / 100 g and saponification of 159.53 ± 0.61; 69.33 ± 0.00 mg KOH / g. Larvae, beef and fish oils have acid values of 3.06 ± 0.01; 6.43 ± 0.05 and 6.33 ± 0.057 KOH / g and peroxides 4.56 ± 0.11; 8.56 ± 0.16 and 7.03 ± 0.05 meq O 2 / kg low. This study shows that late stage R.phoenicis larvae have significant nutrients that are able to balance diets.

“…The most consumed insects belong to the orders Lepidoptera (caterpillars), Coleoptera (beetles), Isoptera (termites), Hymenoptera (bees and ants), Diptera (flies) and Orthoptera (grasshoppers, crickets and crickets) (Anankware et al, 2016;Johnson, 2010;Kelemu et al, 2015). The nutritional value of edible caterpillars in the Congo Basin is confirmed by numerous studies (Van Huis et al, 2014;Foua et al, 2015;Okangola et al, 2016;Ombeni & Munyuli, 2016;Mabossy-Mobouna et al, 2017). This nutritional value can contribute to the qualitative and quantitative improvement of the diet of populations in situations of undernourishment, malnutrition or food crisis (Ambombo, 2022).…”

Edible caterpillars are of vital importance to rural communities in developing countries providing high protein values and income. However, their ecology particularly seasonal fluctuations in their numbers is still poorly understood. With the ongoing climate change and increasing deforestation, their survival is a crucial issue. The aim of this study was to assess the structural characteristics of Petersianthus macrocarpus (Lecythidaceae) on the abundance of edible caterpillars of Imbrasia epimethea (Saturniidea). The forest area on the outskirts of Yaoundé is an important production basin for edible caterpillars making a perfect medium to answer questions on the variations in the abundance of caterpillars of I. epimethea in relation to the forest type of P. macrocarpus. Concerning biometric parameters, the [20-30[ cm diameter class in agroforest had more edible caterpillars (31.1 %). In the secondary forest and swamp forest, it was the [50-60[ cm diameter class with respectively 34 % and 27.4 %. In terms of height, the [30-40[ m height class contained more edible caterpillars (68.50 %), whereas the [60-70[ m height class represented the stratum with the least edible caterpillars (5.10 %). In different forest types, the abundance of caterpillars of I. epimethea according to the social status of P. macrocarpus individuals showed that caterpillars are found in abundance preferentially on dominant individuals (52.7 % in swamp forest, 49.7 % in secondary forest and 45.6 % in agroforest). The mean abundance of I. epimethea caterpillars was higher in secondary forest (563 ± 62 caterpillars) compared to agroforest and swamp forest. In contrast, swamp forest had the lowest mean abundance of edible caterpillars (375 ± 24 caterpillars) according to the social status of P. macrocarpus. These results point way to a better understanding of the use and management of an economically important NTFP.
There are 472 edible insect species in sub-Saharan Africa, of which 31% are Lepidoptera. Wild harvesting is still the main source of supply for these prized species to this day, with some harvesting techniques negatively impacting the environment. The successful production of edible caterpillars requires the appropriate and efficient implementation of husbandry techniques and practices. In this review, we present current literature on edible caterpillars. We provide a general overview of their life history, nutritional composition, and availability associated with specific host plants, with emphasis on semi-domestication and rearing practices that should replace wild harvest. Based on the assimilated information, a proposal of potential species for farming is provided, with details on key characteristics of development cycles to promote the establishment and development of sustainable farms of edible caterpillars at small and large scales. Such advances would contribute toward reducing anthropological pressure related to the exploitation of these food resources, as well as the environmental footprint of this widespread practice.
