Introduction: The storage and preservation of agricultural products remain the only conditions ensuring the almost permanent availability of foodstuffs. However, infestations due to insects and microorganisms are very often noted. Objective: This present work aimed at understanding farmers' constraints, perceptions, and know-how on the post-harvest conservation of cereals and pulses. Place and Duration of Study: A survey was conducted from March 2017 to March 2018 among 320 producers in the Far North region (Cameroon). Methodology: The questionnaire consisted of closed and open questions which mainly related to the principal stored grains, the main constraints, and the usual means of control of stocks. The interview was conducted in a local language (Fulfulde), Arabic and/or French during 25 minutes for each participant. Insect stock photos were also presented to the participants for confirmation of the information given. Results: The results show that producers in our study area are aware of the post-harvest damage and adopt stock control techniques according to the nature of the products, the fate of the grain and the storage structure. The main food crops grown are sorghum (44.4%), cowpea (24.1%) and maize (15.60%). Six main types of storage structure; three methods of storing foodstuffs, five modes of packaging and, six usual methods of control were identified but store maintenance and warehouse monitoring (56.25%) was the most used. According to respondents, insects are the main causes of post-harvest losses. 11 species belonging to four orders were recorded. Conclusion: The producers in our study area are aware of the post-harvest damage and adopt stock control techniques according to the nature of the products, the fate of the grain and the storage structure. But this control would be more efficient if all producers had access to training on storage techniques, isothermal bags or the use of resistant varietal genotypes.
