Unraveling the role of male reproductive tract and haemolymph in cantharidin-exuding Lydus trimaculatus and Mylabris variabilis (Coleoptera: Meloidae): a comparative transcriptomics approach

open access: yesBMC Genomics, 2021
Background Meloidae (blister beetles) are known to synthetize cantharidin (CA), a toxic and defensive terpene mainly stored in male accessory glands (MAG) and emitted outward through reflex-bleeding. Recent progresses in understanding CA biosynthesis and

Comparative mitogenome research revealed the phylogenetics and evolution of the superfamily Tenebrionoidea (Coleoptera: Polyphage). [PDF]

open access: yesEcol Evol
Despite the worldwide distribution and rich diversity of the superfamily Tenebrionoidea, the knowledge of the mitochondrial genomes (mtgenome) characteristics of the superfamily is still very limited, and its phylogenetics and evolution remain unresolved.

The Endosymbiont Consortia of Two Cixiidae Planthoppers Reveal an Ancient Symbiosis With 'Candidatus Mirabilia Symbiotica'. [PDF]

open access: yesEnviron Microbiol Rep
Many insects harbour ancient beneficial endosymbionts that produce essential nutrients. Two planthopper species from the Cixiidae family harbour different tripartite endosymbiont consortia, including a previously unknown and likely ancient Gammaproteobacterium in addition to Karelsulcia and Vidania.

Chemosensory System Decoding: Transcriptome-Wide Identification and Expression Profiling of Olfactory Genes in <i>Lytta sifanica</i>. [PDF]

open access: yesEcol Evol
Lytta sifanica (Coleoptera: Meloidae), a species of significant economic importance, is renowned for its production of the toxic compound cantharidin. In this research, Zhou and colleagues collected specimens of this insect and identified seventy olfactory‐related genes through transcriptomic analysis of adult antennae in L. sifanica. Sequence homology

Antiparasitic properties of cantharidin and the blister beetle berberomeloe majalis (Coleoptera: Meloidae) [PDF]

open access: yesToxins, 2019
Cantharidin (CTD) is a toxic monoterpene produced by blister beetles (Fam. Meloidae) as a chemical defense against predators. Although CTD is highly poisonous to many predator species, some have evolved the ability to feed on poisonous Meloidae, or ...

Light and Electron Microscope Observations of the Male Reproductive Organs of Adult Julodis ehrenbergii Laporte (Coleoptera, Buprestidae). [PDF]

open access: yesMicrosc Res Tech
This study is about the male reproductive organs of Julodis ehrenbergii. To determine morphological and histological characters was used light and scanning electron microscopy were used. The investigation revealed testes, vasa deferentia, accessory glands, and ductus ejaculatorius structures.

An Enigmatic Cretaceous Beetle in Kachin Amber With Tentative Affinities to Pythidae (Coleoptera: Tenebrionoidea). [PDF]

open access: yesEcol Evol
We describe and illustrate a new tenebrionoid beetle from mid‐Cretaceous Kachin amber, Glyphonotum hsiaoi gen. et sp. nov. Based on morphological comparison and phylogenetic analyses, we tentatively place Glyphonotum in the extant family Pythidae, representing the first Mesozoic fossil of this family.

Entomological Surveillance and Cantharidin Concentrations in Mylabris variabilis and Epicauta rufidorsum Blister Beetles in Slovenia

open access: yesAnimals, 2021
True blister beetles (genus Epicauta, family Meloidae) produce cantharidin, which can cause toxicosis in humans and animals. Some recent reports suggest that poisoning by the blister beetle has occurred in the Mediterranean part of Slovenia, which has ...

The first complete 3D reconstruction of a Spanish fly primary larva (Lytta vesicatoria, Meloidae, Coleoptera). [PDF]

open access: yesPLoS ONE, 2012
The first detailed anatomical study of a primary larva of Meloidae is presented. Thereby techniques such as three-dimensional reconstructions, microtome sections, SEM (scanning electronic microscopy) and CLSM (confocal laser scanning microscopy) are ...

Male-Biased Adult Mortality in the Great Bustard Is Consistent With High Reproductive Costs and Aggravated by Anthropogenic Impact. [PDF]

open access: yesEcol Evol
Annual survival of great bustards (Otis tarda) was lower in males than in females, with minimum values just after the mating and incubation period, respectively, a pattern that is consistent with the reproductive cost hypothesis. Survival was lower in Madrid, a highly anthropized region (males: 0.874, females: 0.931), than in Villafáfila, where good ...
