Sugar provisioning maximizes the biocontrol service of parasitoids por Tena, Alejandro, Pekas, Apostolos, Cano, Dalmert, Wackers, Felix L., Urbaneja, Alberto

“…There is increasing interest in the use of food supplements in agriculture to enhance the performance of parasitoids as part of conservation biological control. Nevertheless, there is limited evidence demonstrating the effectiveness of this approach, and this shortage of successful examples raises doubt regarding the validity of this approach. …”

Could sterile males be used to vector a microbiological control agent? The case of Rhynchophorus ferrugineus and Beauveria bassiana por Llácer, Elena, Santiago-Álvarez, Cándido, Jaques, Josep A.

“…Some females from the fungus-challenged treatments showed post-mortem hyphal growth, and this horizontal transmission proves that irradiated males could act as a vector for B. bassiana and should be considered as a new method to improve the biological control of R. ferrugineus.…”

Natal host and learning as factors in host preference by Spalangia cameroni Perkins (Hymenoptera: Pteromalidae) por Tormos, José, Beitia, Francisco J., Asís, Josep D., De-Pedro, Luis

“…The parasitoid Spalangia cameroni Perkins is a commercially available biocontrol agent of filth flies that is also used, especially through inundative releases, for the biological control of fruit flies. Adequate host selection behaviour is essential to the reproductive performance of parasitoid females, and innate and learned host species preferences play a key role in it. …”

The psorosis disease of citrus: a pale light at the end of the tunnel por Moreno, Pedro, Guerri, José, García, María L.

“…However, in the last 2 decades a virus with unusual morphology (Citrus psorosis virus, CPsV) was characterized and closely associated with psorosis disease as previously defined by field symptoms and by biological indexing in sensitive indicator plants. With a tripartite, negative-sense, RNA genome and a ~48 kDa coat protein, CPsV, the presumed causal agent of psorosis, is the type member of the genus Ophiovirus, within the new family Ophioviridae. …”

Global challenges facing plant pathology: multidisciplinary approaches to meet the food security and environmental challenges in the mid‑twenty‑first century por Jeger, Michael, Beresford, Robert, Bock, Clive, Brown, Nathan, Fox, Adrian, Newton, Adrian, Vicent, Antonio, Xu, Xiangming, Yuen, Jonathan

“…In this review we emphasise, in particular: the multidisciplinary links between plant pathology and other disciplines; disease management, including precision agriculture, plant growth and development, and decision analysis and disease risk; the development and use of new and novel plant protection chemicals; new ways of exploiting host genetic diversity including host resistance deployment; a new perspective on biological control and microbial interactions; advances in surveillance and detection technologies; invasion of exotic and re-emerging plant pathogens; and the consequences of climate change affecting all aspects of agriculture, the environment, and their interactions. …”

Guidelines for statistically sound and risk-based surveys of Phyllosticta citricarpa por Lázaro, Elena, Parnell, Stephen, Vicent, Antonio, Schans, Jan, Schenk, Martijn, Schrader, Gritta, Cortinas-Abrahantes, Jose, Zancanaro, Gabriele, Vos, Sybren

“…At the request of the European Commission, EFSA prepared these specific guidelines to guide the surveyor through the design of statistically sound and risk-based surveys for Phyllosticta citricarpa, integrating the key biological information. Based on examples, three different survey designs are simulated:(i) detection surveys to substantiate pest freedom, (ii) delimiting surveys to determine the boundaries of an infested zone, and (iii) buffer zone surveys to monitor a zone ensuring pest detection at low levels of prevalence.The first step of the survey design consists of setting the goals of the survey, characterising the host plant population and the methods used to identify the pest. …”
