Development of integrated control programs using Ceranock "Attract and kill" system and Metarhizium anisopliae to prevent Ceratitis capitata damages in Citrus orchards
This study investigated the potential of Ceranock “attract and kill” system and the entomopathogenic fungus Metarizhium anisopliae to control Ceratitis capitata (Med-fly) infestation. Two control strategies were evaluated under field conditions in two citrus orchards located in the Souss Massa region of south-eastern Morocco. The first control strategy (S1) used 100 Ceranock female bait stations and 100 g of Ceranock male gel per hectare, while the second strategy (S2) used 50 Ceranock female bait stations, 50 g of Ceranock male gel and a ground application of M. anisopliae KN14. Results indicated that both strategies restricted fruit infestation to 0.7% and 0.72%, respectively. In addition, they proved to be successful in substantially reducing the Med-fly population to 44.9 % and 41.7%, respectively. On the other hand, a laboratory bioassay was used to assess the pathogenicity of M.

anisopliae KN14 against different life stages of C. capitata, and mortality rates were 70.53%, 60.91% and 15.29% of the 3rd instar larvae, pupae and adults, respectively.
