The value chain of the edible caterpillar Elaphrodes lactea Gaede (Lepidoptera: Notodontidae) in the Miombo forest of the Democratic Republic of the Congo
BACKGROUND: Elaphrodes lactea Gaede is a highly praised edible lepidopteran insect in the Miombo forest in the DRC. Both caterpillars and pupae of this species are consumed. Following recent declines in the Miombo forest, it is crucial to investigate the rate of consumption, biological, and exploita...

description | BACKGROUND: Elaphrodes lactea Gaede is a highly praised edible lepidopteran insect in the Miombo forest in the DRC. Both caterpillars and pupae of this species are consumed. Following recent declines in the Miombo forest, it is crucial to investigate the rate of consumption, biological, and exploitation cycles, as well as the trade and profitability of E. lactea to develop a sustainable program for its use. METHODS: We, therefore, embarked on a survey in 10 sites located in Lubumbashi between 2011 and 2015. Information on E. lactea supply chain and harvesting period was also documented as well as the mode of selling, pricing, and other determinants of the business. Data were analyzed using R2.15.0 software and means were compared using the Fisher LSD test. RESULTS: The study revealed that E. lactea is the most preferred caterpillar and several indicators guide its exploitation. Caterpillars are available between March and April, and pupation starts in May. Harvesting starts within the household surroundings before reaching the bush, and several harvesting techniques are used. The indirect mode of trade of E. lactea is the most commonly used, with the average price/kg varying between USD2.32 (during in-season = production period for caterpillars) and USD5.24 (during dry season = off-season, mainly pupae). During the peak season of caterpillar production, the harvester’s average income per day varies between USD1.6 and USD3.0 whereas it varies between USD2.2 and USD5.2 during the pupal season. Anthropogenic activities, coupled with climatic factors, constitute the main drivers affecting the availability of E. lactea. CONCLUSIONS: The study, therefore, calls on a concerted action from all stakeholders to increase awareness and the development of innovative measures for sustainable exploitation of this insect while ensuring rehabilitation of the forest through community participation. |
