et al. 2022

Compost and flambéing on the plantain (Musa sp. cv. AAB, var Ngbangele) offshoot power studied under the conditions of Gbadolite in the Democratic Republic of Congo, remain among the techniques that protect the soil and increase production in the face of factors limiting such as climate change and soil destroyer including NPK. The experimental device chosen was that of complete randomized blocks comprising 3 repetitions and 4 plots 3 m long. The plots were arranged so that the flamed cultivars were adjacent depending on the substrates including T0: control substrate or unamended plot; T1: substrate from sawdust; T2: substrate from rice husk; T3: substrate from slush. Each plot contained 10 sample suckers of plantains. The greenhouse was installed after applying the buckling technique. It was observed that a bulb produced an average of 4 weaned suckers in the control bulbs; 8 suckers weaned on bulbs installed on substrates originating from slush; 9 suckers weaned on bulbs planted on substrates made from sawdust and rice husk. The releases installed on the control plot experienced a post-buckling recovery rate of 66.7%; those planted on sawdust and rice husk gave 83.3% and the subjects planted on the substrate from slush experienced a recovery rate of 80%; these results showed that the flame suckers adapted to the greenhouse conditions. In view of these results, it should be noted that this technique remains a major asset for the production of healthy suckers and in large quantities.

“…The town of Gbado-Lite (Figure 1) is located in the Umbrian ecoregion, a subset of the Northeastern Congolian lowland forests. This ecoregion is one of the 200 global priority terrestrial ecoregions known as the « G200 » [Ngbolua, 2018;Ngbolua, 2019a;Ngbolua, 2019b;Ngbolua, 2019c;Ngbolua, 2020a;Ngbolua, 2020b].

The objective of this study was to evaluate the effect of the nature of the food ration on the size, weight, weight gain and ex situ reproduction of the snail (Achatina achatina) in Gbado-Lite. The results of this work show that variations in size [from 8.2±1.2 cm at feeding (D0) to 9.9±2.1 cm at day D84 (snail farm A) and from 8.4±1.1 cm to 10.2±1.8 cm (snail farm B)]; hatching rate [88.2% (snail house A) and 94.2% (snail house B)]; weight [460±18.5 g at loading (D0) to 760±26.3 g on day D84 (snail house A) and 475±10.9 g to 760±26.3 g (snail house B)]; mean absolute weight gain 84 days after loading [37.7±12.0 g (snail house A) and 36.5±9.6 g (snail house B)] were not statistically different between snail houses including mean daily weight gain (0.450±0.1 g/d vs. 0.363±0.1 g/d) and survival rate (90% vs. 100%). Both formulations have the same effect on the reproduction of Achatina achatina in captivity. It is therefore desirable that more in-depth studies be conducted with the aim of popularizing this non-conventional breeding in the city of Gbado-Lite. Thus, in the current context of biodiversity erosion linked to human activities as well as environmental factors, snail farming can contribute to empowerment, improved socio-economic conditions and household resilience to climate change.

The purpose of this study was to conduct a survey of edible caterpillars and the ethno-medical value of their host plants in Gbado-Lite using the "snowball" sampling technique. The results of this study show that Anaphe panda, A. venata, Elaphrodes lactea, Imbrasia epimethea, I. oyemensis, I. truncata and Pseudanthera discrepans are the most consumed caterpillars. Drying is the most used preservation method (82.4%); ground collection is the most used harvesting method (86.3%) while evisceration (45.1%) and dehairing (33.3%) are the main cooking methods used. Harvesting is done more in the forest (94.1%) from May to July (86.3%). The vast majority (98%) of host plants are used in traditional medicine; leaves (53%) and bark (45%) are the most used parts, while decoction is the most used method of preparing therapeutic recipes (92%). The felling of trees (39%) and traditional agriculture (26%) are to varying degrees the main causes of the disappearance of edible caterpillars and their host plants. Incomplete cooking (78.4%) and/or the host plant (19.6%) are the main causes of consumer poisoning. It is therefore desirable that sustainable participatory management strategies for edible caterpillars and their host plants be put in place in North Ubangi Province. These include community agroforestry, which should be practiced in peri-urban areas in order to strengthen the resilience of communities to climate change while at the same time fighting hunger and poverty. Indeed, the domestication of species would allow annihilating the pressure on wild resources, to conserve them, to fight against deforestation and to ensure the availability and sustainability of edible caterpillars. Those phytochemical, pharmacological and toxicological studies could be carried out on host plants in order to identify compounds of medical interest contained in these plants.
