Herein, we compared the effects of a conventional insecticide (dimethoate),used with a plant protection system allowed by organic legislation (mass trapping plus rotenone)against B. oleae , with an untreated control field . The experiments were performed in the Calabria region at Mirto Crosia (on the Ionic side of Cosenza province)in a grove with extensive active insect infestation. In two conventionally treated fields with a surface area of 2 hectares each, two treatments were performed (in August and September) utilizing dimethoate (150 g in 100 liters water). In another 2 hectare area, mass-trapping devices (attract and kill) were installed and treatment with rotenone (Rotena 300 g in 100 l water) was performed in September. The entomo-fauna present in the different areas was evaluated by insect capture utilizing cromotropic traps. The integrated protection system (mass-trapping plus rotenone treatment) led to a reduction in the total number of insects in comparison to the traditional method (dimethoate treatment). It proves the negative effect of the tested organic system on the olive ecosystem entomo-fauna. date: 2007 date_type: published publication: IOBC/WPRS Bulletin publisher: IOBC/WPRS refereed: yes referencetext: Bagnoli, B. 2000: Indagini sull’impatto di dispositivi per la cattura massale di adulti di Bactrocera oleae sull’entomofauna utile dell’oliveto.
