Survey on the current diseases status of local versus improved cassava varieties and their management strategies in Cameroon
Group surveys were conducted in five villages in each of the three resource-use zones of the humid forest zone of Southern Cameroon, to assess insect pests’ incidence and the variation due to forest landscape degradation in the agricultural production systems. 389 farmers were interviewed. The re...

Species composition and fruit fly infestation levels of 12 wild and cultivated cucurbits were determined in field surveys and in on-station trial in Benin. Six fruit fly species including Dacus ciliatus, D. vertebratus, D. bivittatus, D. frontalis, D. Punctatifrons and Bactrocera cucurbitae, were...

In Cameroon, parasitism by Loranthaceae is a limiting factor of the avocado tree cultivation as well as the many diseases and pests which have been better studied. Inventories were carried out in the agroecosystems of five localities around Yaounde, Cameroon. In each one of these localities, all ...

Dominance behaviours and the structure of the dominance hierarchy in colonies of Belonogaster juncea juncea are described. The frequency of these behaviours was recorded for each individual by noting "all occurrences of rare behaviours". Among the dominance behaviours recorded, the most frequent ...
