摘要: Grains and milling products constitute a major part of the daily diet of human and animal. The primary factor in grains and by products losses is the depredation of stored-product beetles. The objective of this trial was the evaluation of insecticidal and repellent activity of essential oils (EOs) from three spp ( , ) which grow wild in Iran, against the red flour beetle, (Coleoptera: Tenebrionidae), known as one of the most common stored-product pests worldwide. EOs were extracted from aerial parts of three spp using a Clevenger type apparatus. Their chemical compositions were analyzed by gas chromatography–mass spectrometry (GC/MS). Results indicated that phenolic compounds, such as thymol and carvacrol, are the main constituents of the EOs. Insecticidal activity on the adult was evaluated by direct contact and fumigation bioassays. EO was the most efficient with the lowest estimated LD and LC as 20.11 μg/adult 2.51 mg/L air, respectively. All the tested EOs were strongly repellent to the adult at the tested concentration (1% v/v). Similarly, oil at 1% (v/v) showed the highest repellent activity (98% to 100%) after 4 h of exposure. Considering the potential toxicity and repellency of the mentioned spp EOs to the red flour beetle, future studies could investigate the practical application of this potential bio-insecticide for the control of this pest.
