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...

A series of experiments was conducted to determine the effect of a flour food source on survival of red flour beetle, Tribolium castaneum (Herbst), and confused flour beetle, Tribolium confusum (DuVal), exposed to the labeled rate (0.5 mg/cm2) of Protect-It, a marine formulation of diatomaceous earth. Beetles were exposed at 27 degrees C, and 40, 57, and 75% RH in 62-cm2 petri dishes. When beet...

Entomopathogenic fungi can regulate insect populations. They have extracellular enzymes that degrade cuticle components, mainly hydrocarbons, used as an energy source. The increase in insecticidal activity of fungi in a medium supplemented with cuticular hydrocarbons was assayed and the hydrolytic enzyme profiles of two strains of Purpureocillium lilacinum were evaluated. A spore suspension of ...

Bu çalışmada; sıcak ve soğuk su yöntemi ile Nigella sativa Lavandula angustifolia bitkilerinden elde edilen ekstraktların üçer farklı (10, 15 20 w/w) konsantrasyonlarına ait süspansiyonları, önemli bir depo zararlısı olan Kırma un biti (Tribolium confusum Jacquelin du Val. (Coleoptera: Tenebrionidae))’nin ergin larva dönemlerine karşı fumigant etkileri üzerine değerlendirilmiştir. Çalışmada ayr...
