Anthracnose caused by Colletotrichum gloeosporioides is a disease that causes losses of cashew production in Benin. This study aims to evaluate the economic losses in cashew nuts caused by the disease. The data were collected using a questionary on a sample of 84 farmers from 12 villages in

This work has compared the effects of the biofertilizer Bacillus amyloliquefaciens FZB42 with that of compost for cotton production. The population dynamics of pests and predators have been studied in order to check whether the use of both fertilization materials can contribute to pest management in cotton. Three treatments were considered: (i) dressing of seeds in rhizobacteria suspension, (ii) introduction of rhizobacterial suspension directly in the pocket, same time with the seeds, and (iii) fertilization with compost. The study was carried out in northwest Benin (West Africa). Results showed that cotton aphids, Aphis gossypii, pink bollworm, Pectinophora gossypiella, leaf roller, Sylepta derogata, and cotton bugs, Dysdercus sp. are the major insect pests encountered in the experimental plots. Cotton bollworm, Helicoverpa armigera, was present but under the economic threshold. The coccinellid predators, Cheilomenes spp., occurred in the experimental plots and almost suppressed aphid proliferation. Other natural enemies such as chrysopids and ant species also occurred and probably contributed to maintain the cotton bollworm under the economic threshold. The treatment with seeds dressed with the rhizobacteria suspension yielded 39% more cotton compared to the compost
