Biological parameters of the predator, Amphibolus venator Klug (Hemiptera: Reduviidae) preying on larvae of Tribolium confusum Duv. (Coleoptera: Tenebrionidae)

Effects of temperature on oviposition and development of Amphibolus venator (Klug) (Hemiptera: Reduviidae), a predator of stored product insects

The egg production and development of Amphibolus venator (Klug) were investigated at five temperatures (25, 27.5, 30, 32.5 and 35°C), 70% r.h. and 16L–8D photoregime. The optimum temperature for multiplication and development of A. venator was around 32.5°C. Pre-oviposition period decreased with increasing temperature. Temperature in the range 25–35°C had no effect on oviposition period. The av...

Efficacy 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 ...

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...

biological effects of citrus peels essential oils against confused flour beetle, tribolium confusum duval (coleoptera: tenebrionidae)

in this research, fumigation efficiency, repellency and persistence of citrus essential oils extracted from dried peels of orange, bitter orange and mandarin (cultivars: satsuma, page, clemantin) were investigated against adults of confused flour beetle tribolium confusum duval. the essential oils were extracted by using clevenger apparatus. 40 ml glass container as bioassay chamber and filter ...
