Abstract

This work aims to develop and evaluate an attractant based on the combination of DAP and Eucalyptus essential oils. Essential oils were isolated by steam distillation from Eucalyptus species and analyzed by GC-MS. About 12 and 22 constituents were identified with 1.8 was the major compounds in crude essential oil and formulations. The adsorption efficacy depends on the abundance of each compound in crude essential oils and the polarity of terpenic components. Results indicated the attractant potential of both essential oils (class III) and that DAP/essential oils formulations accomplished better attractant performance (class IV). Formulations were toxic against medfly adults.

Introduction

MedflyCeratitis capitata (Wiedemann) (Diptera: Tephritidae), is among the major destructive pests of fruits worldwide, in the Mediterranean regions [1,2].InTunisia, Medfly is a key economic pest on citrus and various crops [3]. Current control program is mainly based on applications insecticides [4].their use is subject to much controversy [5].In this respect, botanical extracts and essential oils could be suggested as alternatives[6]. Many essential oils are known for their important insecticidal, pesticidal and repellent/attractant properties. The use of attractants is associated with procedure in which the pest is displaced from a protected resource (crops, fruits, area ...) and concurrently lured [8]. In this respect, it has been demonstrated that plant essential oils could act as insect attractant [9]. Various studies have been cited on attractant potential of eucalyptus essential oils against
