Valorisation de la chenille comestible Bunaeopsis aurantiaca dans la gestion communautaire des forêts du Sud-Kivu (République Démocratique du Congo)

The forests of the Albertine Rift are known for their high biodiversity and the important ecosystem services they provide to millions of inhabitants. However, their conservation and the maintenance of ecosystem service delivery is a challenge, particularly in the Democratic Republic of the Congo. Our research investigates how livelihood strategy and ethnicity affects local perceptions of forest ecosystem services. We collected data through 25 focus-group discussions in villages from distinct ethnic groups, including farmers (Tembo, Shi, and Nyindu) and hunter-gatherers (Twa). Twa identify more food-provisioning services and rank bush meat and honey as the most important. They also show stronger place attachment to the forest than the farmers, who value other ecosystem services, but all rank microclimate regulation as the most important. Our findings help assess ecosystem services trade-offs, highlight the important impacts of restricted access to forests resources for Twa, and point to the need for developing alternative livelihood strategies for these communities.

“…This low value of moisture allows a good physical and qualitative conservation of the larvae slowing considerably their degradation (Muvundja et al, 2012 ;Mabossy et al, 2013). The ash content of R. phoenicis larvae flour (5.02 ± 0.01%) was higher than that of beef (0.46 ± 0.57%) and tuna (1.5 ± 0.1 %) indicates that the larvae of this insect contain a lot of minerals.…”

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 excessive collection of these caterpillars has adverse effects on future harvests [ 22 ]. The availability of edible caterpillars might also be affected by logging, as the host trees of some edible caterpillar are also used as valuable timber (e.g., E. cylindricum ) or artisanal charcoal production [ 105 , 119 , 120 ]. Deforestation destroys the natural habitat of edible caterpillars and their host plants by reducing the amount of foliage used to feed them [ 121 ].…”

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.
