We evaluated formulations of diatomaceous earth and zeolite originated from natural deposits Greece as insecticides in concrete steel surfaces for the control three major beetle species stored products: Sitophilus oryzae (L.) (Coleoptera: Curculionidae), Rhyzopertha dominica (F.) Bostrychidae) Tribolium confusum Jacquelin du Val Tenebrionidae). The were tested dusts at 0.5 or 1 g/m2. Our result...

Background: Flour is one of the most important food sources, therefore it must be kept healthy and clean. As a potential pest control modality, we aimed to examine whether flour irradiation is a feasible tool to eradicate Tribolium confusum adults from infected flour considering probable health effects of infested flour consumption. Materials and Methods: unirradiated and irradiated flour were ...

This report reexamines experimentally the problem of competitive indeterminacy in mixed-species populations of the flour beetles, Tribolium confusum and T. castaneum. Indeterminacy takes the form of alternative competitive outcomes: in some replicate cultures one species exterminates the other with a probability, say p, whereas in others, the opposing species wins with a complementary probabili...

Aqueous extract from leaves of Sambcus ebulus L. were tested for antifeedant, growth regulation and ovicidal effects against the red floor beetle Tribolium confusum Duv. under laboratory condition (29?1?C, RH 60?5% and 12L:12D). The results indicated a significant deterrence for feeding, and comparatively significant larval, pupal and adult weight decrease in treated vs. controlled insects. Sim...

The efficacy of low temperatures ranging from 0 to −15 °C was evaluated against all life stages Tribolium confusum, adults Oryzaephilus surinamensis and Liposcelis bostrychophila. All species/life were exposed in empty vials or containing 5 g flour, for time intervals 2–7 d. Eggs pupae the least susceptible T. as these had highest survival at – 15 °C. Nevertheless, this temperature, an exposure...

In the present study, a total of 17 indigenous entomopathogenic fungal (EPF) isolates (Beauveria bassiana (Bals.) Vuill. – 14, Clonostachys rosea (Link) Schroers 2, Isaria farinosa (Holmsk.) Fr. 1) obtained from soil samples collected Antalya province (southwestern part Turkey) and three commercial EPF products [i.e. Priority® (Paecilomyces fumosoroseus), Nibortem® (Verticillium lecanii) Nostal...

This study was conducted to characterize farmers' post-harvest conservation practices and identify the different storage structures, main pests of cereals in stock, as well mode application insecticides protect seeds against infestations. To these practices, we have prepared a questionnaire answering characteristics population three provinces. The grain structures our region vary depending on l...
