The entomophagy or feeding on insects provides nutritional and economic opportunities. We studied the nutritional value of bee larvae harvested in the Eastern part of the Democratic Republic of Congo. Bees (Apis mellifera L.) named « Bukavu », which come from beehives set in the region of Bukavu and its surroundings (~60 km radius) in a region known traditionally as Bushi, were studied in September 2014. Bee larvae from Bukavu were compared to those available in the Province of Namur (Belgium) and larvae of the wax moth. In Belgium bee larvae were collected from local beehives whereas the larva of the greater wax moth Galleria mellonella were bought from the supermarket. Quantitative analyses of triglycerides, cholesterol, phospholipids and glucose based on specific enzymatic reactions performed. The composition (weight/dry weight) of the Bukavu larvae was made of 20.68% for lipids, 15.40% for proteins and 7.36% for glucose. That of Namur larvae was made of 13.75% for lipids, 31.94% for proteins and 18.43% for glucose. Larvae of the greater wax moth contained 40.14% for lipids, 16.7% for proteins and 0.14% for glucose. These results are equivalent to 251 kcal for the Bukavu bees, 416 kcal for Namur bees and 312 kcal for moth larvae in 100 g of dry weight samples. Mineral element composition (w/dry weight) was 3.07% for Bukavu bee larvae, 6.86% for Namur bee larvae and 2.41% for moth larvae. The nutritional value of bee larvae from Bukavu and Namur depends somehow upon their origin, the environmental conditions including the availability of melliferous plants, and other factors. We conclude that bee larvae (Apis mellifera L) and larvae of the wax moth Galleria mellonella L may be used at a large scale to fight against protein deficiency and malnutrition among the local populations in the region of Bukavu. Their production can be integrated in the management plan of Kahuzi-Biega National Park. Our results are similar to the findings published by other authors on Apis mellifera and Galleria mellonella larvae.

Abstract: (french)
L’entomophagie, le fait de se nourrir d’insectes, présente des avantages à la fois nutritionnels et économiques. Nous avons étudié la valeur nutritive de larves d’abeilles récoltées dans l’Est de la RD Congo. Les abeilles dénommées ‘Bukavu’ ayant fait l’objet de cette étude, proviennent principalement des ruches de Bukavu et ses environs dans la partie communément appelée BUSHI, soit dans un rayon de 60 km autour de la ville de Bukavu (septembre 2014). A titre de comparaison, ont été analysées, des larves d’abeilles récoltées dans la Province de Namur, Belgique (septembre 2014) et de fausse teigne, commercialisées par les supermarchés, octobre 2014). Les analyses quantitatives des triglycérides, cholestérol, phospholipides et glucose se basent sur des réactions enzymatiques spécifiques. Les larves ‘Bukavu’ contiennent, par rapport à 100 g de poids sec, 20,68 g de lipides, 15,40 g de protéines et 7,36 g de glucose. La composition des larves ‘Namur’ par rapport à 100 g de poids sec se composent de 13,75 g de lipides, 31,94 g de protéines et 18,43 g de glucose ; les larves de fausses teignes totalisent 40,14 g de lipides, 16,7 g de protéines et 0,14 g de glucose par 100 g de poids sec. Cette composition met en évidence la valeur énergétique de ces larves qui sont respectivement de 251 kcal, 416 kcal et 312 kcal/100 g de poids sec pour les larves d’abeilles ‘Bukavu’, ‘Namur’, et de fausse teigne. Les éléments minéraux, calcium, magnésium, potassium et sodium par 100 g de poids sec totalisent 3,07 g chez les larves ‘Bukavu, 6,86 g chez les larves ‘Namur’ et 2,41 g chez les larves fausse teigne. La richesse et la composition des larves d’abeilles, récoltées à Bukavu et à Namur, en protéines, lipides, glucose et minéraux dépendent dans une certaine mesure de leur origine et sans doute de la saison, de l’environnement, des plantes mellifères et autres facteurs. Les larves des fausses teignes sont également riches en nutriments. Les larves d’abeille et de fausse teigne pourraient être utilisées à large échelle pour lutter contre les carences protéiques dans les populations de Bukavu et environs mais également être intégrées dans le plan global de gestion et conservation du Parc National de Kahuzi- Biega (Est-RDC). Ces données ne s’écartent pas des valeurs trouvées par d’autres chercheurs sur les larves d’Apis mellifera L. et de celles de Galleria mellonella L.
