As the summer season approaches, the monitoring activity of the olive fly (Bactrocera oleae) has begun.
La mosca dell’olivo è l’agente patogeno più dannoso e pericoloso per gli Ulivi. Può causare la caduta prematura del frutto oltre ad alterare qualitativamente le olive con conseguente aumento dell’acidità dell’olio.
Population development generally stops in the winter period; the fly's flight activity begins at temperatures above 14-18 ° C. High summer temperatures also compromise the survival of adults (above 39-40° C) and larvae (above 33-35° C). Furthermore, in the presence of temperatures above 30° C, there is a decrease in the fecundity of the females.

Starting from mid-June, when the attached olives begin to grow, we have installed traps with pheromones to monitor the olive fly.
Ai fini di una lotta integrata alla mosca, l’utilizzo di trappole con ferormoni consente di seguire la dinamica di popolazione e monitorare l’andamento dei voli degli adulti e il loro numero.
As reported in the technical data sheet of the traps BacTrap distributed in Italy by Biogard , it is a yellow polywave plastic shed trap, equipped with a special support for housing the pheromone dispenser. The inside is sprinkled with glue for catching adults. This trap allows for good levels of effectiveness thanks to the combined action of the pheromone (which attracts males) and the yellow color (which mainly attracts females).
The traps are checked twice a week: the monitoring of adults is strategic to identify the correct positioning of the first preventive treatment based on repellent / anti-deponent products whose success will depend on how promptly the intervention.
When limit thresholds of 5-10% of infested drupes are reached, it becomes necessary to chemically intervene with appropriate treatments.
