Organic farming
In Bockl矇 (Garoua-Cameroon), from August 01 to December 22, 2020, the insecticidal effect of the powders of three plants (Azadirachta indica, Carica papaya and Senna didymobotrya) was observed on the entomofauna of Solanum melongena in order to evaluate the population dynamics of insect pests, to collect data on the number of leaves, flowers and fruits per plant, to study the foraging activity of the floricultural insect Apis mellifera and to determine the cumulative impact of botanical insecticides and this bee on the seed yields of this Solanaceae. The experimental field was arranged in completely randomized blocks. All insecticides tested very significantly reduced the pest population and influenced the activity of floricultural insects. The combined action of the powdered insecticides and flowering insects increased the fruiting rate, the average number of seeds per fruit and the percentage of normal seeds. In order to protect the eggplant crop from insect pests while preserving insect pollinators, the use of botanical insecticides should be encouraged as an alternative to pesticide use.

Performance and potential of local plants
A study on the performance and potential of edible caterpillar plants planted in the Ibi-village SAF was conducted in the Bat矇k矇 Plateau in the Democratic Republic of Congo. The main objective of this study was to evaluate the performance and potential of edible caterpillar plants planted in the Ibi-village agroforestry system and to do so, we used observation as a research method. 35 species of edible caterpillar host plants were identified in this study, divided into 16 families and 7 orders. Regarding the ecological spectra of the floras, Mesophanerophytes and Sarcochores are preponderant. On the phytogeographical level, the strong representativeness of the Guinean-Congolese element. Morphologically, the majority of the species are trees. From this study, the species Pentaclethra eetveldeana is the most dominant species. The most represented families are Fabaceae and Euphorbiaceae.
