Summary Drought affects the complex interactions between Norway spruce, bark beetle Ips typographus and associated microorganisms. We investigated interplay of tree water status, defense carbohydrate reserves with incidence attack infection fungi in mature spruce trees. installed roofs to induce a 2‐yr moderate drought managed stand examine maximum 10 roof control trees for resin flow (RF), predawn twig potentials, terpene, phenolic concentrations, borings field bioassays before after...
Entomology is key to understanding terrestrial and freshwater ecosystems at a time of unprecedented anthropogenic environmental change offers substantial untapped potential benefit humanity in variety ways, from improving agricultural practices managing vector-borne diseases inspiring technological advances.We identified high priority challenges for entomology using an inclusive, open, democratic four-stage prioritisation approach, conducted among the membership affiliates (hereafter...
Allochronic speciation refers to a mode of sympatric in which the differentiation populations is primarily due phenological shift without habitat or host change. However, it has been so far rarely documented. The present paper reports on plausible case allochronic between pine processionary moth (PPM), Thaumetopoea pityocampa . PPM Mediterranean insect with winter larval development. A phenologically atypical population early adult activity and summer development was detected 10 years ago...
We present the first review of Hymenoptera alien to Europe. Our study revealed that nearly 300 species belonging 30 families have been introduced In terms diversity within invertebrate orders, this result ranks third following Coleoptera and Hemiptera. Two are parasitoids or hyperparasitoids were mostly for biological control purposes. Only 35 phytophagous species, 47 predator 3 pollinators introduced. Six wasps (Aphelinidae, Encyrtidae, Eulophidae, Braconidae, Torymidae, Pteromalidae)...
A process of adaptive divergence for tolerance to high temperatures was identified using a rare model system, consisting two sympatric populations Lepidoptera (Thaumetopoea pityocampa) with different life cycle timings, 'mutant' population summer larval development, Leiria SP, and the founder natural population, having winter WP. third, allopatric (Bordeaux WP) also studied. First second instar larvae were experimentally exposed daily-cycles heat treatment reaching maximum values 36, 38, 40...
Abstract Allochrony that is reproductive isolation by time may further lead to divergence of adaptive traits in response different environmental pressures over time. A unique “summer” population the pine processionary moth T haumetopoea pityocampa , reproductively isolated from typical winter populations allochronic differentiation, here analyzed. This allochronically shifted reproduces spring and develops summer, whereas “winter” reproduce late summer have larval development. Both coexist...
Abstract Iridomyrmex humilis (Mayr) and some other ants, through preference, efficient foraging recruitment, quickly removed artificially exposed batches of insect eggs including those the serious pest eucalyptus, Phoracantha semipunctata (Fabricius). This supports evidence importance ants as predators many insects that lay freely eggs. However, P. normally lays in peeling bark crevices where approximately 60% laid within gaps less than ca. 0.65 mm wide could not be reached even by small...
The oviposition behaviour and host selection by females of the pine processionary moth, Thaumetopoea pityocampa, was studied under two conditions: in a field insectary stand. An choice test conducted an cage, using artificial Christmas trees (ACTs) baited with extracts from four species: Pinus pinea, pinaster, halepensis brutia, plus control. Females oviposited significantly more egg batches on ACT P. brutia extract, while no occurred control ACT. In large pinea stand, groups randomly...
Abstract Aim Allochronic speciation occurs when sympatric populations sharing similar feeding regimes diverge because they mate at different times. Such mode is fascinating it permits the study of subsequent adaptations and/or geographic range shifts undergone by that face new ecological constraints. Moreover, exploring whether intraspecific differentiation accompanied niche divergence crucial for planning efficient biodiversity management and invasive species control. Here, we address topic...
Divergence between populations sharing the same habitat can be initiated by different reproductive times, leading to allochronic differentiation. A spatially localized summer population (SP) of pine processionary moth Thaumetopoea pityocampa, recently discovered in Portugal, occurs sympatry with local winter (WP). We examined level genetic differentiation two and estimated current gene flow within spatial framework their co-occurrence. Mitochondrial data indicated that sympatric were...
The pine processionary moth Thaumetopoea pityocampa (Lepidoptera, Notodontidae) is a univoltine defoliator that active over wide range of latitudes and elevations, being largely influenced by temperature variations, especially during larval development across the winter. This work compares field time with observed in laboratory rearing under controlled conditions, four Th. populations characterized different life history phenology: two from Italian Alps early late adult emergence, Portugal,...
Abstract: Female calling behaviour and male response to natural synthetic pheromone sources were used for a Portuguese population of the winter pine processionary moth Thaumetopoea pityocampa (Den. & Schiff.). Virgin females 1–5 days old studied, mean longevity being 3.3 ± 0.7 days. Calling started ≅ 3 h after onset scotophase, 7 emergence, lasting, nightly, 6.4 h, was not affected by female age. A drop in air temperatures during first half scotophase an increase light intensity at dawn...
More than 65% (1040 species) of arthropod species alien to Europe are associated with human-made habitats, especially parks and gardens, human settlements agricultural lands, whereas woodlands yet colonized by less 20% the fauna, which still has a negligible representation in other natural semi-natural habitats. Large differences habitat affinity observed between taxonomic groups. Phytophagous predominant among aliens, representing 47.2% Europe.
