“…In the present study, A. biguttatus developed through four larval instars, in contrast to existing literature, which reports five (Moraal & Hilszczanski, ). Most buprestid larvae develop through four instars (Evans et al ., ), and four have been reported in several congeneric species (Cote & Allen, ; Loerch & Cameron, ; Lyons & Jones, ; Haavik et al ., ; Orlova‐Bienkowskaja & Bieńkowski, ). The pattern of smallest head capsule size at the highest temperatures in second‐instar larvae, although not significant, as well as largest head capsule size at the highest temperatures in fourth‐instar larvae, suggests a shifting thermal optimum (Atkinson, ), with early‐instar larvae attaining optimal growth at lower temperatures, and later‐instar larvae attaining optimal growth at higher temperatures (Fig.…”

1 The two spotted oak buprestid, Agrilus biguttatus Fabricus, is implicated in oak decline events across Europe, and is strongly linked to Acute Oak Decline in the U.K., although its role in the syndrome remains under investigation. In the U.K., the beetle is restricted to south and central England. The present study aimed to improve our understanding of the beetle's life history and thermal requirements, intending to explain its U.K. distribution, and to collect data for lifecycle modelling. 2 Novel methods were developed to collect and culture the beetle in the laboratory, which enabled experiments to be carried out, providing data on the beetle's sex ratio, longevity and fecundity, and the development rates of eggs, larvae and pupae at constant temperatures. 3 On average, females lived for 63 days and laid 82 eggs. Larvae developed through four instars. Sex ratio varied by site, with no overall trend apparent. 4 The development rates of eggs, larvae and pupae (to adult emergence) had linear relationships with temperature, with lower developmental thresholds of 12.1, 11.9 and 15.1 ∘ C, respectively. For each life stage, degree-day values were calculated. Beetles appeared to have an obligatory prepupal diapause at all temperatures studied, up to and including 25 ∘ C. 5 The implications of the developmental findings for the beetle's current distribution, as well as the possible effects of climate change, are discussed. The beetle appears to be thermally limited in the U.K. and, if so, its distribution, and perhaps that of Acute Oak Decline, may alter under climate change.

“…Picea spp. are reported as hosts to the insect vectors M. galloprovincialis, M. sutor and M. sartor (Schroeder & Magnusson, 1992;Evans et al, 2004). As for C. lusitanica, it seems to be a nonhost for M. galloprovincialis, but this will not guarantee protection against B. xylophilus if the insect vector changes host preference or if C. lusitanica is a host for other Monochamus species (which is not yet proven).…”

Susceptibility evaluation of Picea abies and Cupressus lusitanica to the pine wood nematode (Bursaphelenchus xylophilus)

2013

Pine wilt disease (PWD), recently introduced into Europe, is caused by the pine wood nematode (PWN) Bursaphelenchus xylophilus and is a devastating illness that affects mainly pine trees. It is known that the PWN is capable of infecting other conifers; however, there is currently no information on which other plant species may be susceptible to PWD. In this study, the potential susceptibility of two common species of European forests, Picea abies and Cupressus lusitanica, to PWN was assessed through the monitoring of visual external symptoms, dimension and localization of the nematode population in stems, quantification of total chlorophyll, total soluble phenolics and lignin, at 7, 14, 21 and 28 days after inoculation. The degree of susceptibility was established through the comparison of symptoms with Pinus pinaster, a well-known PWN host. Furthermore, the stem ultrastructure of P. abies, C. lusitanica and Pn. pinaster was analysed by scanning electron microscopy. The results suggest that P. abies and C. lusitanica are resistant to PWN, and that lignin biosynthesis in these species is affected at an early stage of the infestation. Nevertheless, P. abies seems to be a compatible host that could act as a repository for PWN.

“…Pm in turn is viewed as a secondary xylophagous or minor pest, mostly developing on weakened and decayed trees (López-Pantoja et al 2011), particularly on those previously damaged by Cw (Torres-Vila et al 2013). It follows that a major challenge for research in sustainable forest management is how to conserve suitable brood material for protected and rare species without risking increased population levels in potentially pest species (Evans et al 2004). Thus, acquiring a deeper knowledge of those longhorns in oak forests is an important task, not only to improve and update biogeographical and faunistic censuses under the global warming scenario, but also to understand major aspects driving population ecology and ecological succession in oak forests, such as habitat occupancy, host tree selection, wood status preference, microhabitat requirements, larval assemblages, intraguild competition and resource partitioning (Ranius and Jansson 2000;Grove 2002;Hanks et al 2005;Buse et al 2007;Iwata et al 2007;Vodka et al 2009;Albert et al 2012).…”

size, altitude and sun exposure. Wood quality and host preference were major factors segregating interspeciic resource partitioning. Cw was prevalent on cork oak decayed wood, and Pm on holm oak degraded wood. Host tree part was involved in Cerambyx larval niche segregation, with Cw prevalent in the fork/branches and Cc in the trunk/base. Pm was never found inhabiting deciduous oaks. Our results may be useful to improve sustainable forest management practices in Iberian oak open woodlands.Abstract Oak open woodlands are widespread in southwestern Iberia and present outstanding ecological, biodiversity and socio-economic values. Evergreen species (holm and cork oaks) are prevalent but deciduous oaks may be also locally important. Three large xylophagous cerambycids are associated to these oaks, Cerambyx welensii (Cw), C. cerdo (Cc) and Prinobius myardi (Pm). Like other saproxylic insects, these cerambycids are essential to the nutrient cycle, wood degradation and tree hollow formation, signiicantly contributing to biodiversity in oak forests. These cerambycids may also potentially colonise healthy living trees and become harmful or pest species. Factors driving their larval ecology are almost unknown, especially in oak forests harbouring mixed populations living in sympatry. Wood samples (n = 500 bolts) from 348 colonised trees were examined during 2011-2016 across the Extremadura region (41,634 km 2 ). Bolts were measured, scored into ive wood quality classes, dissected, and all target cerambycids were collected, measured, reared and taxonomically identiied. We then determined species-speciic prevalence, niche breadth, niche overlap, age structure and population density depending on wood quality, host preference, tree part, wood Electronic supplementary material The online version of this article (
