摘要

The aim of the study was to assess the efficacy of dichloromethane and methanol extracts of two Chenopodiaceae (Salicornia arabica and Suaeda fruticosd) and one Tamaricaceae (Tamarix gal lied) Moroccan medicinal plants for their toxicity against the early second and third instar larvae and adults of Ceratitis capitata: one of the most destructive fruit pest. The activity of the extracts was performed using incorporated plant extracts into diet and determination of lethal concentration 50 value, whereas the mortality of adults was counted after treatment by feeding on cotton discs soaked by different dilutions the extract. The C. capitata larvae and adults were more sensitive to methanol than dichloromethane extracts. The larval mortality was observed after 24 h exposure and the highest activities on larvae and adults were found for T. gallica methanol extract with LC_(50) dose of respectively 0.5% and 30 mg mL~(-1). The methanol extract of T. gallica found to be highly effective against C. capitatais potential to be used as an ideal ecofriendly approach for the control of this insect.
