El ácido jasmónico señaliza la respuesta de los cítricos a la sequía
Ediciones y Promociones LAV (2012)El estrés hídrico afecta a diferentes parámetros fisiológicos en cítricos además de reducir la producción y la calidad de los frutos. Las plantas responden a la sequía regulando el estado hídrico y aumentando la abscisión ... -
Can summer and fall vegetative growth regulate the incidence of Tetranychus urticae Koch on clementine fruit?
Elsevier (2008)Fruit scarring caused by Tetranychus urticae is one of the main pest problems faced by Spanish clementine growers as it can downgrade the quality of the fruit completely. T. urticae infestations concentrate on fruit at the ... -
Changes in predation and parasitism of the citrus leafminer Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) populations in Spain following establishment of Citrostichus phyllocnistoides (Hymenoptera: Eulophidae)
Elsevier (2010)The citrus leafminer, Phyllocnistis citrella, is a pest native to Southeast Asia which threatened the citrus industry in the Mediterranean region upon its introduction in 1993. Immediately afterward, a classical biological ... -
Citrus plants exude proline and phytohormones under abiotic stress conditions
Springer Verlag (2017)Key message This article describes the root exudation of proline and phytohormones in citrus and their involvement in salt- and heat-stress responses. Abstract Plants are constantly releasing several compounds to the ... -
Compatibility of Phytoseiulus persimilis and Neoseiulus californicus (Acari: Phytoseiidae) with imidacloprid to manage clementine nursery pests
Elsevier (2013-01)Biological control is not common in citrus nurseries where chemical control is prevalent. The systemic neonicotinoid imidacloprid applied as a drench is effective against three out of four key pests of young clementine ... -
Control químico de Pezothrips Kellyanus, nueva plaga de los cítricos, y sus efectos sobre la entomofauna auxiliar
Ediciones y Promociones LAV (2009)Pezothrips kellyanus (Bagnall) (Thysanoptera: Thripidae) es una nueva plaga para los cítricos en España. Este trips se alimenta de los frutos recién formados produciendo una escarificación circular alrededor del peciolo ... -
Controlled in vivo infestation of mandarin fruit with Ceratitis capitata for development of quarantine treatments
Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (2008)Movement of citrus fruit from Ceratitis capitata-infested areas requires mandatory quarantine treatments. Development of such treatments requires the use of infested fruit. The in vivo approach is the most realistic way ... -
