Insecticidal and repellent activity of three Satureja species against adult red flour beetles, Tribolium castaneum (Coleoptera: Tenebrionidae)

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 Satureja spp (S. khuzestanica, S. rechingeri and S. bachtiarica) which grow wild in Iran, against the red flour beetle, Tribolium castaneum (Coleoptera: Tenebrionidae), known as one of the most common stored-product pests worldwide.
