Millet crop-loss assessment methods (NRI Bulletin 62)

At present, losses to the millet crop of Sahelian subsistence farmers are seldom adequately monitored, yet an assessment of such losses is essential in evaluating the effects of and need for different farming inputs and methods. Millet Crop-Loss Assessment Methods offers a range of assessment techniques, each presented as a sequence of steps, including sampling, calculation interpretation and comparative accuracy. Choice of the most appropriate method will depend on government or farmer needs, time constraints and available skills. This publication will be of interest to all those involved in practical agricultural research and extension work in semi-arid areas, either at the level of the individual farmer or village or at the regional and national level of policy evaluation

Pesticides on millet in Mali (NRI Bulletin 50)

The Mali Millet Pest Project (Projet Pilote Britannique), financed by Britain's Overseas Development Administration (ODA) studied the control of millet pests in north-west Mali between 1985 and 1991. The project was executed by Mali's Service National de Protection des vegetaux (SNPV) and ODA's Natural Resources Institute (NRI). These six years of observations, field trials and socio-economic research have produced a wealth of information on the pests of Sahelian millet

Revision of Aresceutica (Orthoptera: Acrididae: Catantopinae) with comments on related genera

The East African forest genus Aresceutica Karsch is revised; there are now four valid species, including A. nguruensis, sp. n. from south eastern Tanzania. Aresceutica is extremely similar to the West African genus Serpusia; it differs only in the form of the prosternal tubercle and the detail of the phallic morphology. Two new combinations are proposed: Ptemoblax lemarineli Bolívar, 1911 = Aresceutica lemarineli (Bolívar, 1911), comb. n. and Aresceutica vansomereni Kevan, 1956 = Duviardia vansomereni (Kevan, 1956), comb. n
