Catmint oil and hydrogenated catmint oil were evaluated as repellents for adult Tribolium casteneum (Herbst) (Coleoptera: Tenebrionidae), the red flour beetle, and T. confusum (DuVal), the confused flour beetle, using both a traditional method of visual assessment of distribution and a video recording method to determine movement patterns of individual insects. Visual assessments of distributio...

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...

In the present work, we examined the insecticidal effect of spinosad, against adults of the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), the confused flour beetle, Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae) on wheat and the larger grain borer, Prostephanus truncatus (Horn) (Col...

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...

The insect growth regulator methoprene can be mixed into the matrix used to comprise bags and other packaging materials. Different methodologies were utilized to evaluate the efficacy of different types of methoprene-treated packaging towards Tribolium castaneum (Herbst), the red flour beetle, and T. confusum Jacquelin duVal, the confused flour beetle, two common insect species that infest stor...

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...
