Effects of Dietary Intake of Volcanic ash from Puyehue Cordon Caulle onTenebrio molitor(Coleoptera: Tenebrionidae) Larvae Under Laboratory Conditions

“…Previous studies on insecticidal activity of volcanic ash in laboratory exposure bioassays on Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), Sitophilus oryzae (L.) (Coleoptera: Curculionidae), and Dichroplus vittigerum (Blanchard) (Orthoptera: Acrididae) have shown the acute insecticidal effect of volcanic ash from Puyehue Cordon Caulle through contact toxicity (Buteler et al 2011;Buteler et al 2014;Fernández-Arhex et al 2016). Kuriwada & Reddy (2016) found that the fallen ash adheres to the surface of plants and insects. The fallen ash has been reported to have reduced dehydration tolerance (Kuriwada & Reddy 2016) and mating behavior in the field cricket Gryllus bimaculatus (De Geer) (Orthoptera: Gryllidae).…”

“…Kuriwada & Reddy (2016) found that the fallen ash adheres to the surface of plants and insects. The fallen ash has been reported to have reduced dehydration tolerance (Kuriwada & Reddy 2016) and mating behavior in the field cricket Gryllus bimaculatus (De Geer) (Orthoptera: Gryllidae). The present study investigated the potential for chronic dietary intake and sub-lethal effects of volcanic ash given that most studies have assessed contact toxicity.…”
