Stictococcus vayssierei is a major pest of root and tuber crops in central Africa. However, data on its ecology are lacking. Here we provide an updated estimate of its distribution with the aim of facilitating the sustainable control of its populations. Surveys conducted in nine countries encompa...

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 ...
