Infestation of cereals and pulses in the field by stored products insects and two new records of stored products coleoptera in Uganda
(1970) Nyiira, Z. M.
Some crops are known to be infested by insects associated with stored produce while still in the field. In Uganda, maize and beans are infested by Sitophilus Oryzae or S. zeamais and Acanthoscelides obtectus respectively, in the field. Samples of sorghum (Sorghum vulgare), maize (Zea mays), beans (Phaseolus vulgaris, Pigeon peas (Cajanus cajan) and grams (Phaseolus spp) collected from the filed and incubated in the laboratory, contained 18 spices of insects associated with stored products. Except for the one moth all of these were beetles. During inspection of stores and mills, two additional beetles species were recorded. These are Carcinopos quatiuordecimstriata (Stephens) (Histeridae) and Lyprops badius Hopes (tenebrionidae). An unidentified bruchid which resembled Acanthoscelides obtecurs was found to be common on sorghum in the field.
