Distribution and efficacy of pyrethrin aerosol to control Tribolium confusum (Coleoptera: Tenebrionidae) in food storage facilities
A field test was conducted whereby adult Tribolium confusum (du Val), the confused flour beetle, were exposed in Petri dishes lined with filter paper and containing 0–2000mg of flour, to a pyrethrin–CO2 aerosol inside an empty warehouse. Applications were made according to label directions, and beetles were exposed to the aerosol for 2 h. After exposure, knockdown was assessed, and beetles were...
متن کاملEfficacy of a volatile formulation of hydroprene (Pointsourcet) to control Tribolium castaneum and Tribolium confusum (Coleoptera: Tenebrionidae)
Threeand 4-week-old Tribolium castaneum (Herbst), the red flour beetle, and Tribolium confusum (du Val), the confused flour beetle, were exposed at five different temperature–relative humidity (r.h.) combinations to a volatile formulation of the insect growth regulator (IGR) hydroprene (called Pointsourcet). Typical effects associated with IGR exposure, such as arrested larval growth, morpholog...
متن کاملEfficacy of chlorfenapyr against Tribolium castaneum and Tribolium confusum (Coleoptera: Tenebrionidae) adults exposed on concrete, vinyl tile, and plywood surfaces
The insecticidal pyrrole chlorfenapyr was applied to concrete, vinyl tile, and plywood surfaces, at an application rate of 1.1 gAIm . Adult Tribolium castaneum (Herbst), the red flour beetle, and adult Tribolium confusum (Du Val), the confused flour beetle, were exposed for 2 and 4 h, removed, and held without food for 7 d post-exposure. All beetles survived the initial exposures, but survival ...
متن کاملGenetic structure of Tribolium castaneum (Coleoptera: Tenebrionidae) populations in mills.
The red flour beetle, Tribolium castaneum (Herbst), is primarily found associated with human structures such as wheat and rice mills. Such structures are predicted to be spatially isolated resource patches with frequent population bottlenecks that should influence their genetic structure. Genetic diversity and differentiation among nine populations of T. castaneum collected from wheat and rice...
متن کاملMolecular techniques for detection of Tribolium confusum infestations in stored products.
The confused flour beetle, Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae) is a stored-product pest that contaminates a wide range of food products, from flour and cereals to spices. The insect reduces food quality and is responsible for large economic losses every year. Although several methods for detection of stored-product pests are common and widely used, they are time-cons...
