Cerambyx cerdo (Cc) is a protected saproxylic beetle in Europe, although it is increasingly reported as an oak 'pest'. Cc ecological features are relatively well known, but, its reproductive biology is still poorly understood. Hence, we investigated the reproductive traits of Cc under laboratory conditions. In females, body length was 44.1 ± 0.9 mm, 28-53 (mean ± SE, range); fecundity 143 ± 11 eggs, 33-347; fertility 78 ± 1%, 65-93; oviposition period 44 ± 3 days, 13-128 and longevity 59 ± 5 days, 16-157. Fecundity was positively correlated with female size, longevity and oviposition period. Daily fecundity was 3.5 ± 0.2 eggs/day, 0.9-6.5 showing a fluctuating synovigenic pattern with a slight decreasing trend over time. Egg length was 3.74 ± 0.01 mm, 2.3-6.0 and egg volume 5.45 ± 0.04 mm3, 2.4-9.6. Egg size was correlated with female size, but, the relative size of eggs was larger in smaller females. Incubation time was 13.5 ± 0.1 days, 7-28. Hatching was superior in larger eggs and neonate size was positively correlated to egg volume. Females were polyandrous (up to 19 matings), but, multiple mating did not enhance fecundity or fertility. In males, body length was 41.8 ± 0.8 mm, 29-53 and longevity 49 ± 3 days, 9-124. Male longevity was unrelated to body size. Males were polygynous (up to 16 matings) and mating number did not affect male longevity. Overall, females were larger and lived longer than males. Cc reproductive traits are compared with those other Cerambycidae, especially with the congeneric pest Cerambyx welensii. Our data may be valuable to improve the protection/management measures of Cc in dehesa woodlands and other oak forests.

“…Therefore, ield-collected Cerambyx larvae were reared in the laboratory until adulthood and then identiied to species. Larvae were individually reared at room temperature (22-28 °C and 50-70% relative humidity) in aerated 140 ml plastic containers on an agar-based artiicial diet (Morales-Rodríguez et al 2015). Containers were regularly inspected and newly formed pupae were kept in rolls of laboratory blotting paper (15-20 mm in diameter, 21 cm long) sealed at both ends and arranged horizontally in plastic trays.…”

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 (

“…However, from the applied point of view, the interest may be distinct depending on the current pest/endangered status of each species (or population) in a given context. For instance, adult dispersal in Cw may be important in relation to preventive measures, sampling procedures, population monitoring, population outbreaks, biological control, pest risk models or mass trapping (Torres-Vila et al, 2012, 2013Morales-Rodríguez et al, 2015). In the case of Cc, adult dispersal may be relevant to gene flow, inbreeding depression, population mobility, species occupancy in uninterrupted and fragmented landscapes, setting of corridors among host patches, metapopulation dynamics, local extinction risk, and, in general, to adopt evidence-based strategies for improving habitat management and conservation biology (Thomas, 2000;Ranius, 2006;Buse et al, 2007;Holland, 2009;Drag et al, 2011;Clobert et al, 2012).…”

Abstract. 1. Cerambyx welensii (Cw) and Cerambyx cerdo (Cc) are two large saproxylic beetles living on Quercus trees in the Western Palearctic whose current pest and legal status differs markedly. Cw is an emerging pest involved in oak decline while Cc is an internationally protected species.2. Acquiring knowledge of the ecology, demography and behaviour of Cw and Cc in forests harbouring mixed populations is a demanding task to optimise their management or protection. Here, we report the results of a mark-recapture study on the flight behaviour and dispersal potential of both species in holm oak open woodlands.3. Average flights, dispersal rates and diffusion models were remarkably similar in Cw and Cc, reflecting a low-dispersal tendency and sedentary behaviour. However, a subset of adults in both species exhibited a huge propensity to disperse and flew more than 1 km. An aggregated distribution of dispersal distances suggested that a behavioural polymorphism might underlie the flight pattern.4. Adults moved preferentially in those spatial directions with neighbouring trees, while prevailing winds did not significantly affect dispersal patterns. The main interspecific differences were as follows: (i) Cc performed longer crosswind flights than Cw on windy days; (ii) Cc tended to fly farther than Cw at low temperatures; and (iii) adult feeding improved dispersal but only in small Cw females. Moon phase did not affect flight activity.5. The results are discussed in an effort to interpret how these ecological and behavioural differences might shape the life history of both congeneric species when they live in sympatry in dehesa woodlands.
