Response of Navel Lane Late citrus trees to regulated deficit irrigation: yield components and fruit composition por Ballester, Carlos, Castel, Juan R., Intrigliolo, Diego S., Castel, Juan R.

“…In conclusion, we suggest that RDI-1 strategy since it did not significantly impair the economic return can be applied in commercial orchards in case of water scarcity. Nevertheless, Navel Lane Late fruit is sensitive to water deficit and the fruit weight can be detrimentally affected.…”

Inoculum and disease dynamics of circular leaf spot of persimmon caused by Mycosphaerella nawae under semi-arid conditions por Vicent, Antonio, Bassimba, Daniel, Hinarejos, Concha, Mira, José L.

“…Most infections coincided with rains, but the disease was observed also on trap plants exposed to less than 1 mm of precipitation and even in the absence of rain. Orchards were flood irrigated once inoculum deposits in the leaf litter had already been depleted, so it was not possible to determine its effects on ascospore release and disease development. …”

A new mechanised cultural practice to reduce Ceratitis capitata Wied. populations in area-wide IPM por Chueca, Patricia, Garcerá, Cruz, Urbaneja, Alberto, Moltó, Enrique

“…Finally, the effect of the mechanised grinding of fallen fruit on C. capitata populations was evaluated for two consecutive years in commercial citrus orchards. The results showed a significant 27-46% reduction in C. capitata populations the following spring, thus demonstrating that the newly proposed mechanised alternative can be included in the current area-wide IPM of the pest in Spain.…”

Density and phenology of the invasive mealybug Delottococcus aberiae on citrus: implications for integrated pest management por Martínez-Blay, Victoria, Pérez-Rodríguez, Jésica, Tena, Alejandro, Soto, Antonia

“…This research aims to examine the seasonal trend of D. aberiae in citrus, using several sampling methods, as a first step to develop an integrated pest management program. Ten citrus orchards from Eastern Spain were periodically sampled during three years using absolute (plant material) and relative (corrugated cardboard band traps and sticky traps) sampling methods. …”

Intraguild interactions between two biological control agents in citrus fruit: implications for biological control of medfly por Tormos, José, Beitia, Francisco J., Asís, Josep D., De-Pedro, Luis

“…The parasitoid wasp Spalangia cameroni and the predatory beetle Pseudoophonus rufipes have long been studied for use as biological control agents against the Mediterranean fruit fly Ceratitis capitata, particularly in citrus fruit orchards. Nevertheless, these two species of natural enemies, when competing for a common resource, may experience intraguild predation (IGP) interactions. …”
