Evaluation of the efficacy of Steinernema carpocapsae against the Red Palm Weevil, Rhynchophorus ferrugineus in Phoenix canariensis

The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), is an important pest of palms. It has recently colonized the Mediterranean Basin, where it is a serious problem on ornamental Phoenix canariensis (Chabaud) palms. The efficacy of Steinernema carpocapsae (Weiser) (Nematoda: Steinernematidae) in a chitosan formulation (Biorend R®) against this weevil in a semi-field trial including both preventative and curative assays has been studied. Our results prove the potential of this nematode to control R. ferrugineus. Efficacies around 80% were obtained in the curative assay, and up to 98% in the preventative treatment. Applications repeated every 2–3 weeks during the critical flight periods could prove effective to protect palms from this weevil in the Mediterranean Basi

Distributed goal-oriented computing

For current computing frameworks, the ability to dynamically use the resources that are allocated in the network has become a key success factor. As long as the size of the network increases, it is more difficult to find how to solve the problems that the users are presenting. Users usually do know what they want to do, but they do not know how to do it. If the user knows its goals it could be easier to help him with a different approach. In this work we present a new computing paradigm based on goals. This paradigm is called Distributed goal-oriented computing paradigm. To implement this paradigm an execution framework for a goal-oriented operating system has been designed. In this paradigm users express their goals and the OS is in charge of helping the achievement of these goals by means of a service-oriented approach. © 2012 Elsevier Inc.

Effect of variable photoperiod on development and survival of Cirrospilus sp. nr. Lyncus (Hymenoptera: Eulophidae), an ectoparasitoid of phyllocnistis citrella (Lepidoptera: Gracillariidae)

No differences could be observed neither in development times nor on survival of C. sp. near lyncus exposed to three different photoperiods: 16:8; 12:12 and 8:16 (L.D). Therefore, conservation tactics aimed at favoring the winter permanence of this species in citrus orchards could increase the impact of this opportunistic parasitoid on its host P. citrella

Evaluation of the efficacy of Steinernema carpocapsae in a chitosan formulation against the red palm weevil, Rhynchophorus ferrugineus, in Phoenix canariensis

The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), is an important pest of palms. It has recently colonized the Mediterranean Basin, where it is a serious problem on ornamental Phoenix canariensis (Chabaud) palms. The efficacy of Steinernema carpocapsae (Weiser) (Nematoda: Steinernematidae) in a chitosan formulation (Biorend R(A (R))) against this weevil in a semi-field trial including both preventative and curative assays has been studied. Our results prove the potential of this nematode to control R. ferrugineus. Efficacies around 80% were obtained in the curative assay, and up to 98% in the preventative treatment.

Estudio de la relación entre los balances en superficie de onda larga y onda corta utilizando datos del proyecto SRB (Surface Radiation Budget)

Ponencia presentada en: III Congreso de la Asociación Española de Climatología “El agua y el clima”, celebrado en Palma de Mallorca del 16 al 19 de junio de 2002.[ES]En este trabajo se muestra la influencia de diferentes regímenes climáticos en el balance de radiación en superficie, a través de las comparaciones entre los balances de onda larga y onda corta en diferentes regiones del globo. Las regiones estudiadas son cuatro zonas desérticas o semidesérticas, seis oceánicas y dos localizadas en el Mediterráneo. Se observa una gran influencia de la cobertura nubosa en los balances de radiación de onda corta y larga, así como el efecto estacional en ambos hemisferios. Asimismo, aparecen diferencias claras si comparamos regiones del Mar Mediterráneo con regiones centrales del Océano Pacífico o el Atlántico.[EN]In this work we show the influence of different climatic regimes on the surface radiation balance through the comparisons between the long wave balance and the short wave balance over different regions in the globe. The studied regions are four deserted or semi-deserted areas, six ocean areas and two areas located in the Mediterranean basin. A large influence of cloud cover is observed in both short wave and long wave balances, as well as the seasonal effect in both hemispheres. Likewise, remarkable differences appear if we compare Mediterranean Sea regions with central regions of the Pacific or Atlantic Oceans
