VERDOMINANCE for viability of newly arising mutant polygenes has been reported by several investigators in the past decade in Drosophila melanogaster and Tribolium confusum [WALLACE 1957, 1958, 1959, 1963; BURDICK and MUKAI 1958; MUKAI 1961; MUKAI, YOSHIKAWA, and SANO 1966; CRENSHAW 1965 (in radiation-induced mutations). MUKAI, CHIGUSA, and YOSHIKAWA 1964, 1965; MUKAI and YAMAZAKI 1968 (in spon...

Studies on the production of plant-based pest control strategies have been growing in recent years. Origanum (Lamiaceae) species are important medicinal aromatic plants and many studies conducted their biological activities. This study was to determine repellent effects plant essential oils extracted from four different species: O. onites, vulgare var. hirtum, verticium onites × vulgare, agains...

We examined the insecticidal effect of three different dust formulations, which were attapulgite (W), mix with oregano essential oil 52% carvacrol (D1), and 75% (D2), in four major stored-product beetle species, Sitophilus oryzae (L.), Tribolium confusum Jacquelin du Val, Rhyzopertha dominica (F.), Trogoderma granarium Everts. was most susceptible at all followed by T. R. dominica. In contrast,...

Seed germination performance is one of the most essential development stages in medicinal and aromatic plants that may be unfavourably affected by the phytochemicals released from other plants in the soil environment. The present research was conducted in the laboratory to study the allelopathic effect of Erythroxylum monogynum Roxb. to the germination and growth parameters of Solanum lycopersi...

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...
