“…The dominant indigenous pine species in Galicia, P. pinaster , was the most frequent host of S. noctilio (accounting for 45% of >8000 emergences) in the extensive surveys of Europe, Turkey, and North Africa by Spradbery & Kirk ([20]; with the other important hosts being P. halapensis , P. sylvestris , and P. brutia at 17, 12, and 11%). We also doubt that the landscape abundance of pine stands was limiting to S. noctilio in Galicia because there are >4000 km 2 of pine forest and the distance among stands is generally modest relative to the flight capabilities of S. noctilio [81], [82]. Meteorological conditions can be a constraint on forest insect populations (e.g., [83]–[85]), but this is unlikely as a general explanation for the low abundance of S. noctilio in Galicia because the species occurs throughout the Iberian Peninsula and into North Africa; CLIMEX models indicate that S. noctilio is as well suited to Galicia as to places where it can be a pest [86].…”

Accelerating introductions of forest insects challenge decision-makers who might or might not respond with surveillance programs, quarantines, eradication efforts, or biological control programs. Comparing ecological controls on indigenous vs. introduced populations could inform responses to new introductions. We studied the European woodwasp, Sirex noctilio, which is not a pest in its native forests, is a serious invasive pest in the southern hemisphere, and now has an uncertain future in North America after its introduction there. Indigenous populations of S. noctilio (in Galicia, Spain) resembled those in New York in that S. noctilio were largely restricted to suppressed trees that were also dying for other reasons, and still only some dying trees showed evidence of S. noctilio: 20–40% and 35–51% in Galicia and New York, respectively. In both areas, P. sylvestris (native to Europe) was the species most likely to have attacks in non-suppressed trees. P. resinosa, native to North America, does not appear dangerously susceptible to S. noctilio. P. radiata, which sustains high damage in the southern hemisphere, is apparently not innately susceptible because in Galicia it was less often used by native S. noctilio than either native pine (P. pinaster and P. sylvestris). Silvicultural practices in Galicia that maintain basal area at 25–40 m2/ha limit S. noctilio abundance. More than 25 species of other xylophagous insects feed on pine in Galicia, but co-occurrences with S. noctilio were infrequent, so strong interspecific competition seemed unlikely. Evidently, S. noctilio in northeastern North America will be more similar to indigenous populations in Europe, where it is not a pest, than to introduced populations in the southern hemisphere, where it is. However, S. noctilio populations could behave differently when they reach forests of the southeastern U.S., where tree species, soils, climate, ecology, management, and landscape configurations of pine stands are different.

We studied the distribution and spread of the invasive social wasp Vespula germanica in Argentina, focusing on the contribution of queen dispersal to territorial expansion. Vespula germanica is native to Eurasia and has invaded several regions of the world, including Southern Argentina. Flight potential of field-collected queens was measured using flight mills. Also, by means of an extensive survey we estimated the rate of spread by analysing the relationship between years since arrival and distance from the introduction locality. The mean distance flown by wasp queens in flight mills was 404.7 Ϯ 140.8 m (mean Ϯ SE, n = 59), while the rate of spread of V. germanica was estimated at 37.2 Ϯ 2.1 km year -1 (mean Ϯ SE, n = 67), although faster towards the south. The observed spread rate of V. germanica wasps in Argentina confirms the invasive potential shown by several Hymenoptera species worldwide. Still, a stratified geographical expansion pattern does not match observed queen dispersal abilities, suggesting that human-aided transport of hibernating queens is the central driver of the current distribution of these wasps. We suggest that despite several life-history traits known for social insects that contribute to successful invasion, wasp spread must still rely strongly on human mediated pathways. This observation sheds light on those factors that are crucial for managing invasions of this and related pestiferous wasps.

“…To quantify flying ability, adult females were individually introduced into a flight mill adapted from the device of Schumacher et al . (Schumacher et al ., ; Bruzzone et al ., ). Data recorded from such experimental devices are known to overestimate the total distance and total time an insect does usually travel by flight (Bruzzone et al ., ) as compared with mark–release–recapture data (Botero‐Garces & Isaacs, ).…”

Dormancy and dispersal are thought to be major adaptive mechanisms that enable short‐lived organisms to cope with environmental stochasticity. The few empirical investigations that have explored the relationship between these two strategies in disturbed environments have focused mainly on communities of annual desert plants and suggest that dispersal plays a negligible role, as compared with dormancy, in reducing the risk of genotype extinction. We predict that the relative advantage of dormancy versus dispersal is likely to be more balanced in species that disperse actively to select their reproductive locality. To examine this prediction, we explored the dormancy and dispersal capacities of four actively dispersing sibling weevil species (Curculio spp.) that exploit the same, highly variable resource (oak acorns). The ability of each species to spread risks over time was estimated from the variability of dormancy duration within cohorts, while their ability to disperse spatially was quantified by flight performance. We show that a first species, C. elephas, which was able to spread risk over time through dormancy, exhibited only medium flight capacities. In contrast, a second species, C. glandium, was able to fly over very long distances, but was hardly capable of spreading risk over time. Surprisingly, the two remaining species (C. venosus and C. pellitus) proved inefficient in spreading risk either in space or in time and seem to exhibit risk avoidance rather than risk‐spreading strategy. We conclude that this strong diversification of dispersal–dormancy strategies observed among these four sibling species might contribute to stabilising their coexistence.
