Abstract A survey was carried out between March and August 2010 to identify insect pests of stored yam chips in Ogbomoso Metropolis, Nigeria. Dried yam chips were randomly obtained from old stocks in 6 local markets within the metropolis on monthly basis. There was a significant (P < 0.05) difference in insect abundance based on month of sampling and insect species. Dinoderus porcellus (Coleoptera: Bostrychidae) was the most abundant species. Other species encountered were Araecerus fasciculatus (Degeer) (Coleoptera: Anthribidae), Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) and Tribolium castaneum Herbst (Coleoptera: Tenebrionidae). When chips were infested with Dinoderus porcellus and stored for 3 months, reconstituted thick paste (amala) was made from the flour and was evaluated for consumers’ acceptability. Sensory characteristics such as odour, colour, texture, appearance, taste and overall acceptability were significantly (P < 0.05) affected when compared with the paste prepared from the uninfested chips.

Neste trabalho a meta principal foi avaliar a suscetibilidade dos adultos de Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae) e Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) e a qualidade fisiológica dos grãos de milho submetidos ao tratamento com ozônio, em diferentes camadas da massa de grãos, razão pela qual se construíram gaiolas de 3,0 cm de altura e 15,0 cm de diâmetro, em PVC, sendo o fundo e a tampa confeccionados em tecido do tipo organza; as gaiolas foram dispostas em recipientes cilíndricos, também em PVC, com 20 cm de diâmetro, 100 cm de altura e conexões para injeção e exaustão do gás ozônio. Tanto os insetos quanto os grãos de milho foram submetidos a uma atmosfera modificada com 50 mg kg-1 de ozônio injetado a um fluxo contínuo de 8,0 L min-1 em conexão localizada na base (plenum) do recipiente, em diferentes períodos de exposição. A espécie que se mostrou mais susceptível foi a S. zeamais, independentemente da sua distribuição na massa de grãos. O menor período de exposição para controlar 95% dos adultos de S. zeamais e T. castaneum foi de 23,76 e 64,19 h, respectivamente, quando distribuídos próximos à injeção do gás ozônio; em geral, os tratamentos com atmosfera modificada com 50 mg kg-1 de ozônio não afetaram a qualidade fisiológica dos grãos de milho.

Considerando-se as altas temperaturas nos graneleiros junto à esteira transportadora de grãos objetivou-se, neste trabalho, avaliar a influência da temperatura no momento da pulverização, sobre a eficácia biológica do bifentrina. Para isso, pulverizou-se o inseticida sobre grãos de milho dentro de uma câmara climática nas temperaturas de 25, 30, 35, 40, 45 e 50 ºC, com umidade relativa em torno de 55%. Após a pulverização e a cada 15 dias, até completar 90 dias, foram feitas as análises da eficácia biológica utilizando-se os insetos Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae) e Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). Observou-se tendência decrescente da eficácia biológica do bifentrina com o aumento da temperatura do ar ambiente, no momento da pulverização e com o maior tempo de armazenamento dos grãos de milho, resultando em menor mortalidade dos insetos-praga.

Okra Abelmoschus esculentus (L.) Moench (Malvales: Malvaceae) is a major fruit vegetable consumed in either fresh or dried form in Africa. As part of our efforts to identify the pestiferous species attacking dried fruits, a laboratory experiment was conducted to investigate the damage potentials of Sitophilus zeamais (Motschulsky, 1855) (Coleoptera: Curculionidae) and Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidae) against dried okra. Three levels of infestations (5, 10 and 20 adults of each insect) on dried okra and okra without insect infestation, which served as control were kept under ambient conditions. The experiment was laid out in completely randomized design and replicated thrice. Data were collected on percentage insect mortality, okra weight loss and proximate composition. Percentage mortality increased with storage duration, while weight loss was significantly affected by insect infestation levels and ranged from 0.04%-0.18%, 0.07%-0.21%, 0.08% 0.22%, 0.07%-022%, 0.11% 0.22% and 0.12%-0.23% for 1, 2, 3, 4, 5 and 6 weeks after infestation, respectively. Crude fibre significantly increased with insect infestation (13.98%-14.62% for the infested okra compared with 9.12%-13.63% in the control), while other proximate components were not significantly affected. The results show that the two species pose no serious threat to intact dried okra, in the short term, but long term multiple generation infestation of dried okra by the insects may cause greater damage.

Research studies were carried out to evaluate insecticidal action of two plant products and a synthetic insecticide on a major stored-product insect, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The plant species studied were, Piper nigrum and Eucalyptus camaldulensis, whereas methoprene used as synthetic insecticide. Two formulations viz., powder and ethanol extract of each plant and four concentrations (5ppm, 10ppm, 15ppm and 20 ppm) of methoprene were tested. Repellency was tested using the filter paper test whereas mortality, weight loss protection and anti-feedant potential of all treatments was evaluated by using whole maize grains. Our results were highly significant as compared to control however; P. nigrum was more effective as compared to E. camaldulensis. The investigation of cumulative effects of botanical and synthetic insecticide and isolation of active ingredients of botanicals are further issues to be investigated for their inclusion in. I. P. M programs.
