The psyllid Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is one of the most important pests of citrus worldwide because it efficiently vectors three bacteria in the genus Candidatus Liberibacter that cause the devastating citrus greening disease (huanglongbing). Current management practices for this insect pest rely on multiple sprays of foliar insecticides and one or two applications of so...

Shipments of 50,000 commercially reared Aphytis melinus DeBach were obtained from each of the five insectaries that produce and sell this parasitoid to citrus growers in California for control of California red scale, Aonidiella aurantii (Maskell). Shipments were received from each insectary every 2 mo over a period of a year to assess variability in quality through time and between insectarie...

Conversion of wastewater to reclaimed water for crop irrigation conserves water and is an effective way to handle a growing urban problem: the disposal of wastewater. Water Conserv II is a large reclaimed water project developed by Orlando and Orange County, Fla., that presently irrigates ≈1900 ha of citrus. The project includes a research component to evaluate the response of citrus to irrigat...

Salinity is a major agriculture problem for citrus in the Mediterranean basin, which global producer region. Citrus crops are also threatened by emerging diseases such as Huanglongbing (HLB). The use of different rootstocks increases variability plant material orchards, thus preventing extensive damage caused abiotic and/or biotic diseases. In this work, we have evaluated salinity response five...
