To better understand the phenology of R. ferrugineus populations in the Mediterranean basin, the objective of the present work has been to estimate the effect of temperatures within the range 10[long dash]25[degree]C on the reproductive parameters of R. ferrugineus and to determine its lower temperature thresholds for oviposition and egg hatching. Our results confirm that oviposition in R. ferrugineus is strongly affected by temperature. Lower thresholds for oviposition and egg hatching (15.45[degree] and 13.95[degree]C, respectively) are below the mean monthly temperatures registered in winter in most of the northern shore of the Mediterranean basin. Under these circumstances, new palm infestations would be difficult during most of the winter. These results should be taken into account when planning some palm management practices, such as pruning or pesticide treatments, in areas under a Mediterranean climate.10aRhynchophorus ferrugineus1 aDembilio, O.1 aTapia, G., V.1 aTellez, M., M.1 aJacas, J., A.  uhttps://weevil.myspecies.info/lower-temperature-thresholds-oviposition-and-egg-hatching-red-palm-weevil-rhynchophorus-ferrugineus03187nas a2200157   4500008004100000245015500041210006900196260001200265300000900277490000600286520253700292653003002829100001702859700001802876856013502894       2012                        eng d00aBio-ecology and integrated management of the red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae), in the region of Valencia (Spain)0 aBioecology and integrated management of the red palm weevil Rhyn  cJanuary  a1-120 v53 aThe invasive red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera: Curculioni- dae), is one of the most destructive pests of palms in the world. It is widely distributed in all continents and has been reported on 26 palm species belonging to 16 different genera. In the Mediterranean basin, R. ferrugineus has become the major pest of palms, mainly Phoenix canariensis hort. ex Chabaud, an endemic palm to the Canary Islands widely used as ornamental. In this manuscript we summarize the research that the UJI-IVIA Unit has carried out on this pest. The first objective of our work was to determine different bio-ecological parameters of R. ferrugineus under natural conditions in a Mediterranean climate. Washingtonia filifera is the only palm species included in our studies showing mechanisms of complete resistance against R. ferrugineus. Although Chamaerops humilis and Phoenix theophrasti show antixenotic and antibiotic mechanisms of resistance, respectively, they cannot be considered as resistant against R. ferrugineus. Under Mediterranean climate, the preimaginal development of R. ferrugineus in P. canariensis takes 666.5 DD and the weevil can complete 13 larval instars. Based on the results obtained, less than one generation per year can be expected in areas with a mean annual temperature (MAT) below 15[degree]C and more than two in those with MAT above 19[degree]C. Oviposition in R. ferrugineus is also strongly affected by temperature. The thresholds for oviposition and egg hatching obtained are very close to MAT registered in most of the northern shore of the Mediterranean basin. Under these circum- stances, no new infestations would be expected during most of the winter. The second objective has been to improve chemical and biological control. Both imidacloprid and Steinernema carpocapsae in a chitosan formulation are highly effective against R. ferrugineus in the field. Different timings and product combinations were studied, and high efficacies were obtained in all cases. An indigenous strain of Beauveria bassiana, found naturally infecting pupae of R. ferrugineus, resulted highly virulent against all developmental stages of the weevil in the laboratory. Additionally, adults of either sex inoculated with the fungus efficiently transmitted the disease to healthy adults of the opposite sex and this result confirmed the potential of B. bassiana as a biological control agent against this pest. These results should help developing an integrated management program against this pest.10aRhynchophorus ferrugineus1 aDembilio, O.1 aJacas, J., A.  uhttps://weevil.myspecies.info/bio-ecology-and-integrated-management-red-palm-weevil-rhynchophorus-ferrugineus-coleoptera-curculion02498nas a2200193   4500008004100000020001400041245018400055210006900239260000800308300001200316490000700328520172800335653003002063100002002093700001902113700002002132700001702152856013502169       2012                        eng d  a1742-758400aGeographic information system-based study to ascertain the spatial and temporal spread of red palm weevil Rhynchophorus ferrugineus (Coleoptera: Curculionidae) in date plantations0 aGeographic information systembased study to ascertain the spatia  cJun  a108-1150 v323 aRed palm weevil Rhynchophorus ferrugineus Olivier is a key pest of date palm in the Kingdom of Saudi Arabia. Since 1994, the Ministry of Agriculture has implemented a pheromone-based integrated pest management (IPM) strategy to control R. ferrugineus in the Kingdom. Geographic information system (GIS) technology can serve as a valuable tool to assess insect activity and in addition the impact of the control strategy. We used GIS-based techniques to ascertain the spatial and temporal spread of R. ferrugineus in 234 ha of date plantation in Al-Sohemia-1 in the Al-Ahsa region of Saudi Arabia. One hundred and fifty six pheromone (Ferrolure(TM)) traps in Al-Sohemia-1 were logged using the Trimble global positioning system to determine the east longitude and north latitude of each pheromone trap and transformed to the GIS as a shape file. The spatial and temporal variations for R. ferrugineus activity based on captures in pheromone traps were studied for each of the four seasons of the year and also year-wise during 2009 and 2010. Results revealed that during both 2009 and 2010, maximum weevil activity was recorded during late spring and early summer, with captures declining during autumn and winter. Spatial variations in the activity of R. ferrugineus indicated that in general 2009 registered lower weevil activity compared with 2010. Furthermore, most of the area exhibited medium to very high weevil activity in spring and summer during both 2009 and 2010, while most of the area recorded very low to low weevil activity during the autumn and winter seasons of both the years. The ongoing R. ferrugineus-IPM programme in Al-Ahsa needs to be strengthened in areas showing high to very high weevil activity.10aRhynchophorus ferrugineus1 aMassoud, M., A.1 aSallam, A., A.1 aFaleiro, J., R.1 aAl-Abdan, S.  uhttps://weevil.myspecies.info/geographic-information-system-based-study-ascertain-spatial-and-temporal-spread-red-palm-weevil-rhyn
