Chemical composition and insecticidal efficacy of essential oil of Echinophora platiloba DC (Apiaceae) from Zagros foothills, Iran
Essential oil of Echinophora platyloba was screened for its chemical composition and possible fumigant and contact toxicity effects against Tribolium castaneum (Herbst), Callosobruchus maculatus (F.) and Rhyzopertha dominica (F.). Aerial parts were subjected to hydrodistillation and obtained oil che...

| Summary: | Essential oil of Echinophora platyloba was screened for its chemical composition and possible fumigant and contact toxicity effects against Tribolium castaneum (Herbst), Callosobruchus maculatus (F.) and Rhyzopertha dominica (F.). Aerial parts were subjected to hydrodistillation and obtained oil chemical composition was analyzed by GC-MS. (Z)-β-ocimene (33.06 %), p-cymene (10.98 %) and Limonene (5.77 %) were major constituents. Fumigation tests were performed for 24, 48 and 72 h, while contact toxicity of essential oil was evaluated in 24h. Experimental units were located in 25±2 °C and darkness condition. In contact toxicity evaluation tests T. castaneum (LC50= 14.712 μl/39cm2) was more tolerant and R. dominica (LC50= 9.712 μl/39cm2) was more susceptible species. After 24 h, T. castaneum (LC50= 39.658 μl/250 ml air) and C. maculatus (LC50= 3.835 μl/250 ml air) were more tolerant and susceptible species in fumigation bioassays, respectively. In general, mortality increased as the doses of essential oil and exposure time increased. |
