Abstract

Modern agriculture requires technology to give precise measures about relevant parameters such as pest control. Here, we developed an algorithm model as base for bait spray intervention, by monitoring the olive fruit fly, Bactrocera oleae (Rossi), with conventional traps, in 24.3 Hectares of non-irrigated Baladi olive cultivars, in Hassbaya region. We installed 49 yellow sticky traps with ammonium bicarbonate. The adults, males and females were monitored, on weekly basis. The traps and the trees were georeferenced, and the parameters such as temperature, relative humidity, tree phenology (BBCH), and fruit load rate were compiled. The results showed that the infested fruits were correlated as much with the fruit load rate as with the number of adults captures which were correlated more to the temperature than the relative humidity. The number of the males captured was higher than the females all over the cultivation period. The first symptoms of the fruits were observed from 22 September when the BBCH was equal to 85%, with an average of adult captures lesser than 5 adults by trap by 7 days.
