The plantation and natural forests of South America have been highly impacted by native exotic pests in recent decades. interaction emerging invasive pests, climate change, timber markets will define the region’s forests, with significant but uncertain ecological changes economic losses expected. Southern Cone Forest Health Group (SCFHG), a joint ad hoc initiative run forest health professionals from Argentina, Brazil, Chile, Uruguay, aims to strengthen relationships between forestry...
We describe flight variability in the woodwasp Sirex noctilio Fabricius, 1793 (Hymenoptera: Siricidae) by studying tethered females a mill device and analyzing output data time series methodology. Twenty-eight wasps were flown during 24 h-long periods, under controlled temperature lighting conditions. The maximum distance recorded was 49 km, mean velocity 0.37 m s(-1). All lost weight (mean loss of 10.0% initial body mass). By using wavelets analysis on output, we identified three distinct...
Early detection and monitoring of invasive forest pests are crucial for effective pest management, particularly in preventing large-scale damage, reducing eradication costs, improving overall control effectiveness. This study investigates the potential machine learning models remote sensing at various spatiotemporal scales to assess damage caused by woodwasp Sirex noctilio pine plantations. A Random Forest (RF) model was applied analyze Planetscope satellite images Sirex-affected areas...
Abstract The woodwasp Sirex noctilio F. (Hymenoptera: Siricidae) is probably the most important pest of pine tree plantations southern hemisphere. We studied spatial arrangement an endemic population S. within located in northwest Patagonia, Argentina, during three successive years since colonization. By censusing healthy and attacked trees, which provided data on current past yearly attacks, we studied: (i) pattern trees phase a population, (ii) changes through time with increasing (i.e.,...
The invasive woodwasp Sirex noctilio has become one of the most significant pests pine forests throughout northern and southern hemispheres. In Patagonia (southern Argentina), S. was first detected in early 1990s. However, less than two decades, despite intensive control efforts, populations have spread, outbreaks been observed. this paper, we outline define several key ecological behavioral features (namely, spatiotemporal population dynamics, phenology dispersal) briefly discuss their...
Abstract The wood‐boring wasp, Sirex noctilio , is a global invasive pest that infects and kills pine trees by inoculating spores of symbiotic fungus ( Amylostereum areolatum ) at oviposition. Wasp larvae depend on fungal growth to feed, while the relies female wasps initially condition tree phytotoxic venom for dispersal. use as an external gut digestion lignocellulosic compounds resulting in strong correlation between inside wood wasp fitness. This study explores hypothesis will volatiles...
Abstract 1 Sirex noctilio F. ( Hymenoptera: Siricidae ) is a wood‐boring wasp that attacks many pine species, including commercial trees planted throughout the world. Management of its populations largely based on biological control using nematode Beddingia siricidicola . Adult females are sterilized by nematode, but free to move and attack new trees, promoting dispersal. Although generally successful, management through introductions has sometimes been inadequate. 2 We evaluated effect...
Abstract Sirex noctilio is an invasive forest wasp that affects pines in many parts of the globe and can result severe economic losses. Current trapping methods for monitoring pest rely heavily on non‐specific semiochemicals. This lack specificity translate into low attraction/capture levels, something undesired, especially when intent to detect still at population densities. In this context, interesting opportunity arises increase trap sensitivity by incorporating visual cues. For this, we...
Abstract S irex noctilio F abricius ( H ymenoptera: iricidae), an invasive woodwasp from pain and N orth A frica, has expanding global presence in pine forests. Although their populations are managed most parts of the world, success rate existing prevention control strategies been historically variable, there is consensus that monitoring techniques could be improved with increased knowledge about behavioral biology this insect. We conducted descriptive field studies plantations northern P...
1. The movement of organisms can be driven by multiple factors and has implications for fitness the spatial distribution populations. Insects spend a large proportion their adult lives foraging flying resources; however, capability motivation to move vary across individuals. 2. aims this study were examine interindividual sex differences in flight performance characteristics, using mill bioassay, Megarhyssa nortoni (Hymenoptera; Ichneumonidae), parasitoid invasive woodwasp Sirex noctilio...
Understanding the factors that affect animal dispersal behavior is important from both fundamental and applied perspectives. Dispersal can have clear evolutionary ecological consequences, but for nonnative insect pests, capacity also help to explain invasion success. Vespula germanica a social wasp that, in last century, has successfully invaded several regions of world, showing one highest spread rates reported insect. In contrast with nonsocial wasps, species, queens are responsible...
Abstract Accidental and intentional global movement of species has increased the frequency novel plant–insect interactions. In Patagonia, European woodwasp, Sirex noctilio , invaded commercial plantations North American pines. We compared patterns resin defenses S. -caused mortality at two mixed-species forests near San Carlos de Bariloche, Argentina. observed lower levels flow higher in Pinus contorta with ponderosa . general, attacked trees neighboring trees. Resin production P. was not...
Pest responses to landscape complexity show variable patterns globally, primarily related species traits and specific managed habitats. Leaf-cutting ants (LCAs) are native insects important pests of plantation forests in South America. We evaluated the LCA nests young Eucalyptus plantations different spatial contexts: land uses, interfaces (adjacent use pairs), agroecosystems, landscapes. selected 30 sites littoral region Argentina representing three types uses neighboring plantations: adult...
Abstract Sympatric-related species often exhibit resource partitioning. This can occur through different mechanisms, such as behavioral, morphological, and sensory variations, leading to qualitative, temporal, or spatial differences in exploitation, consuming types of food. Sensory-based niche partitioning could be the underlying mechanism which closely related effectively reduce overlap. Here we ask whether variations responses carbohydrates reflect foraging patterns two Vespula present...
Abstract In order to increase the probability of reproduction, social insects can adopt various mate‐finding strategies, such as increasing densities males at specific locations, and/or visual and chemical cues that attract opposite sex. field laboratory studies we investigated strategies used by invasive eusocial wasp V espula germanica ( F abricius) H ymenoptera: espidae). tethered flight assays, established contrasting patterns in females may partly explain how related individuals...
