Anatomical and Histological Structures of the Male Reproductive System of Chalcophora mariana (Linnaeus, 1758) (Coleoptera: Buprestidae): Light and Scanning Electron Microscopy Study

open access: yesActa Zoologica, EarlyView.
ABSTRACT This study presents the first detailed morphological analysis of the male reproductive system of Chalcophora mariana (Linnaeus, 1758) using stereo microscopy, light microscopy, and scanning electron microscopy. The male reproductive system of C.

Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

open access: yesActa Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...

Quantifying dispersal of a non-aggressive saprophytic bark beetle.

open access: yesPLoS ONE, 2017
Long distance dispersal to locate suitable breeding sites is recognized as a key trait influencing the population dynamics and distribution of bark beetles and other saprophytic insects. While dispersal behavior has been studied for a range of aggressive

Histomorphology Structure of the Gastric Caecum, Midgut, and Malpighian Tubules in Adult Flatheaded Pine Borer Chalcophora mariana (Linnaeus, 1758) (Coleoptera: Buprestidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT The pine weevil is one of the largest species in the jewel beetle (Buprestidae) family found in Central Europe and Turkey. Chalcophora mariana is generally considered a secondary guest and primarily develops in weakened, decaying, or recently dead pine trees.

Same Same, but Different: A Glossary of Carcino‐Entomology as a Basis for an Improved Communication and for a Modern View of Carcinology Encompassing Entomology

open access: yesActa Zoologica, EarlyView.
ABSTRACT One core aspect of science is communication, both among researchers as well as with the public. For successful communication, it is crucial that the terminology used is clear to avoid misunderstandings. Especially when researchers working on different groups of organisms communicate, they often use different terms for similar morphological ...

Fine fluorescent powder marking study of dispersal in the spruce bark beetle, Ips typographus (Coleoptera: Scolytidae)

open access: yesEuropean Journal of Entomology, 2016
A novel method was used to study dispersal in the spruce bark beetle, Ips typographus (L.), under epidemic conditions (rapidly increasing population density) in the Šumava National Park. Infested spruce logs were coated with a fine fluorescent powder and

Preference‐performance relationship in the thistle tortoise beetle: Implications for its realised host range

open access: yesEcological Entomology, EarlyView.
There was a positive relationship between adult preference and larval performance. However, the strength of the relationship ranged from weak to strong depending on the measure of adult preference. The adult beetle showed substantial flexibility in host plant selection and equal performance across most thistle hosts.

Small birches matter: Beetle diversity on burned birch and pine in boreal forests

open access: yesInsect Conservation and Diversity, EarlyView.
Burned birch hosted higher beetle richness than burned pine. Higher beetle richness on birch was associated with its greater post‐fire mortality, with charred, dead birches attracting more specialized beetles. Retaining burned birch alongside pine can enhance saproxylic and pyrophilous beetle diversity after prescribed burning.

Evaluation of drone system for thinning operations–a case study in Sweden

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Thinning operations in forestry typically involve a two‐machine system (TMS) with a harvester and a forwarder. Its productivity in different forest conditions is well documented. To date, drones have been used for data collection and surveillance but not as an alternative to a TMS.
