Trypanosomes are known as widespread blood parasites of birds; however, knowledge of their prevalences in vectors and their overall biodiversity is rather limited. To assess the prevalences in potential vectors, we have microscopically examined ornithophilic bloodsucking Diptera (Culicidae, Simuliidae and Hippoboscidae) for the presence of trypanosomatids in their guts. In total, 3270 specimens...

Larval and adult Tribolium confusum were tested in flour and sand substrates at various relative humidities, ranging from 10% to 90%. Both life stages preferred a flour environment of from 10% to 50% relative humidity. In sand, however, the insects selected more humid environments. Investigations of survival in sand, flour, and air environments indicated that two factors may be operating in the...

Tribolium confusum and Sitophilus oryzae are stored product pests found worldwide. Environmental damages, human health issues the emergence of resistance driving scientists to seek alternatives synthetic insecticides for its control. Under this scenario, plant secondary metabolites being increasingly studied as bioinsecticides because they renewable, natural, biodegradable, non-persistent in en...
