Transiting hot Jupiters from WASP-South, Euler and TRAPPIST: WASP-95b to WASP-101b [PDF]
, 2013 We report the discovery of the transiting exoplanets WASP-95b, WASP-96b, WASP-97b, WASP-98b, WASP-99b, WASP-100b and WASP-101b. All are hot Jupiters with orbital periods in the range 2.1 to 5.7 d, masses of 0.5 to 2.8 Mjup, and radii of 1.1 to 1.4 Rjup. The orbits of all the planets are compatible with zero eccentricity.

European Journal of Entomology, 2015 The Asian chestnut gall wasp (ACGW), Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae), is a global pest of chestnut trees. This pest was first recorded in Slovenia in 2005.

Methods in Ecology and Evolution, EarlyView.Abstract Wild bees (Hymenoptera: Anthophila) are important pollinators and essential for maintaining ecosystem health. The majority of bee species are ground‐nesting, and all bees spend most of their lifetime inside the nest. Still, most studies and monitoring schemes assess wild bees during flower visitation, allowing no conclusion about their nest ...

Host-feeding enhances stability of discrete-time host-parasitoid population dynamic models [PDF]
arXiv, 2015 Discrete-time models are the traditional approach for capturing population dynamics of a host-parasitoid system. Recent work has introduced a semi-discrete framework for obtaining model update functions that connect host-parasitoid population levels from year-to-year.

Multi-band characterization of the hot Jupiters: WASP-5b, WASP-44b and WASP-46b [PDF]
, 2017 We have carried out a campaign to characterize the hot Jupiters WASP-5b, WASP-44b and WASP-46b using multiband photometry collected at the Observat\'orio do Pico Dos Dias in Brazil. We have determined the planetary physical properties and new transit ephemerides for these systems.

PLoS ONE, 2012 Parasitoid diversity in terrestrial ecosystems is enormous. However, ecological processes underpinning their evolutionary diversification in association with other trophic groups are still unclear. Specialisation and interdependencies among chalcid wasps

Agricultural and Forest Entomology, EarlyView.Abstract This review provides a synthesis of the available knowledge on Carmenta foraseminis, an emerging cocoa pest in northern South America. This moth was first described in 1995 in Panama, and its proliferation across the Amazon basin is currently threatening the production of cocoa in the region and may endanger the sector's sustainability. Hence,

Detecting non-binomial sex allocation when developmental mortality operates [PDF]
arXiv, 2016 Optimal sex allocation theory is one of the most intricately developed areas of evolutionary ecology. Under a range of conditions, particularly under population sub-division, selection favours sex being allocated to offspring non-randomly, generating non-binomial variances of offspring group sex ratios.

A Comparative Analysis of Host--Parasitoid Models with Density Dependence Preceding Parasitism [PDF]
arXiv, 2020 We present a systematic comparison and analysis of four discrete-time, host--parasitoid models. For each model, we specify that density-dependent effects occur prior to parasitism in the life cycle of the host. We compare density-dependent growth functions arising from the Beverton--Holt and Ricker maps, as well as parasitism functions assuming either ...

Agricultural and Forest Entomology, EarlyView.Abstract Invasive eucalypt psyllids pose a threat to the long‐term production of eucalypts worldwide. In order to reduce their economic impact, classical biological control using Psyllaephagus species has been used successfully. The objectives of this study were to determine the host specificity and host stage preference of Psyllaephagus blastopsyllae,
