“…In our case, the structural connectivity also positively influenced the detritivore/tourist populations. In general, field margins have greater arthropod abundance and diversity than the agricultural fields (Botero‐Garcés & Isaacs, ; Denys & Tscharntke, ) and can provide potential refuge and food resources for flower‐visiting, non‐pest insects and predatory arthropods (Lagerlöf & Wallin, ). The suitability of these field margins as habitat for natural enemies can also depend on the width of the margin and the way margin vegetation is managed.…”

Increasing landscape heterogeneity of agroecosystems can enhance natural enemy populations and promote biological control. However, little is known about the multiscale effects of landscape heterogeneity on arthropod communities in rice agroecosystems, especially in combination with trophic interactions. We examined for the first time how landscape heterogeneity, measured by four independent metrics of landscape composition and configuration at three spatial scales, affected species abundance and species richness of rice arthropods within four functional groups and the abundance of the most common species at 28 sites in the Philippines. We additionally examined the influence of trophic interactions among these functional groups. We found that both the compositional and configurational landscape heterogeneity in combination with trophic interactions determined the structure of rice‐arthropod communities. Herbivore abundance decreased with increasing landscape diversity. The abundance of parasitoids and species richness of both parasitoids and predators increased with the structural connectivity of rice bunds. Fragmentation of the rice landscape had a clear negative effect on most arthropod groups, except for highly mobile predatory arthropods. Abundance of common predators and detritivore species decreased with increasing complexity in the shape of rice patches. Trophic interactions, measured as the abundance of prey, outweighed the importance of landscape heterogeneity for predators. In contrast, parasitoids responded positively to configurational landscape heterogeneity but were unaffected by prey abundance. Synthesis and applications. Our research shows how landscape heterogeneity and trophic interactions have different effects on different functional groups. While predator abundance was solely driven by the availability of prey, all other functional groups in the rice‐arthropod community were significantly affected by the composition and configuration of surrounding landscape features. Landscape management aiming to improve biodiversity and biological control in rice agroecosystems should promote a diversity of land uses and habitat types within 100–300 m radii to reduce the presence of pests. Management practices should also focus on maintaining smaller rice patches and the structural connectivity of rice bunds to enhance populations of the natural enemies of rice pests. Future research should focus on the temporal and spatial manipulation of rice fields to maximize the effects of biological control.

“…Insects are continuously stimulated to fly, due to permanent stimulation resulting from a lack of tarsal contact (Edwards ) and flight performances recorded on flight mills are often an entire order of magnitude greater than those obtained in flight chambers (Shirai and Kosugi ; Yamanaka et al. ) or in mark–release–recapture experiments (Botero‐Garces and Isaacs ). However, these alternative methods generally provide underestimates of flight capacity, due to spatial constraints (size of the chamber, distance of traps from the release point, for example Franzen and Nilsson ).…”

The pine wood nematode (Bursaphelenchus xylophilus), which causes the symptoms of pine wilt disease, is recognized worldwide as a major forest pest. It was introduced into Portugal in 1999. It is transmitted between trees almost exclusively by longhorn beetles of the genus Monochamus, including, in particular, M. galloprovincialis (Coleoptera: Cerambycidae) in maritime pine forests. Accurate estimates of the flight capacity of this insect vector are required if we are to understand and predict the spread of pine wilt disease in Europe. Using computer‐linked flight mills, we evaluated the distance flown, the flight probability and speed of M. galloprovincialis throughout adulthood and investigated the effects of age, sex and body weight on these flight performances, which are proxies for dispersal capacity. The within‐population variability of flight performance in M. galloprovincialis was high, with a mean distance of 16 km flown over the lifetime of the beetle. Age and body weight had a significant positive effect on flight capacity, but there was no difference in performance between males and females. These findings have important implications for managing the spread of the pine wood nematode in European forests.

“…To quantify flying ability, adult females were individually introduced into a flight mill adapted from the device of Schumacher et al (Schumacher et al, 1997;Bruzzone et al, 2009). 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, 2009) as compared with mark-release-recapture data (Botero-Garces & Isaacs, 2004). It nevertheless corroborates trends found in the field and is efficient at detecting the differences possibly existing between several species (Chen et al, 2006) or between individuals of the same species (e.g.…”

Dispersal and dormancy strategies among insect species competing for a pulsed resource

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.
