Analysis of two larval-pupla parasitoids (Hymenoptera, braconidae) in th biological control of ceratitis capitata (Wiedemann) in Spanih Mediterranean areas (original) (raw)

2016

Abstract

The Mediterranean fruit fly, Ceratitis capitata (Diptera: Tephritidae), is considered a key pest in fresh fruit and citrus production in the Mediterranean Bassin. Nowadays, it is being studied the use of several ecological methods against this pest in some Mediterranean countries (Spain, Morocco and Tunisia), like the Sterile Insect Technique (SIT), the classical biological control (CBC) and the search for native parasitoids. Two exotic larval - pupal parasitoids of fruit-flies have been imported by the IVIA to Spain: Diachasmimorpha tryoni and D. longicaudata. As it occurs in other countries, in Spain it is being studied the combined use of the SIT and overflooding releases of parasitoids to combat Medfly populations. To achieve this, only one parasitoid species is usually mass reared and released. Over the last two years we have been analyzing the competitiveness of D. longicaudata and D. tryoni in order to choose the species to be used together the SIT for the integrated control ...
