Insect phylogeny has recently been the focus of renewed interest as advances in sequencing techniques make it possible to rapidly generate large amounts of genomic or transcriptomic data for a species of interest. However, large numbers of markers are not sufficient to guarantee accurate phylogenetic reconstruction, and the choice of the model of sequence evolution as well as adequate taxonomic...

The pre-appearance interval (PAI) is an interval preceding appearance of an insect taxon on a cadaver. It decreases with an increase in temperature in several forensically-relevant insects. Therefore, forensic entomologists developed temperature methods for the estimation of PAI. In the current study these methods were tested in the case of adult and larval Necrodes littoralis (Coleoptera: Silp...

Calviaexplanata sp. n. (Coleoptera: Coccinellidae), externally similar to and commonly misidentified as Calviaalbida Bielawski, is described from India and Nepal.

Cadavers are colonized by different species of animals, mainly insects such as flies and beetles (Kocarek, 2003). The succession of these insects and the time they live on the carcasses is used to determine in which circumstances death occurred and to estimate the postmortem interval (Catts and Goff, 1992). The Coleoptera order is the richest and most diverse of the Insecta class with 350,000 s...

Two new species of Laboulbeniales are described: Laboulbenia parasyphraeae, parasitic on Parasyphraea sp. (Coleoptera, Chrysomelidae, Alticinae), and L. skelleyi, parasitic on Pselaphacus rubricatus and P. signatus (Coleoptera, Erotylidae). Other recorded species are Chaetomyces pinophili, Chitonomyces aurantiacus, Corethromyces ophitis, Dimorphomyces platensis, Dioicomyces anthici, D. cf. noto...

Navia nom. nov. is proposed for Euterpia Navia & Flechtmann, 2005 (Prostigmata: Eriophyoidea), preoccupied by Euterpia Bondar, 1942 (Insecta: Coleoptera: Curculionidae).

Phenylphenalenone-type compounds accumulated in the tissues of two banana cultivars-Musa acuminata cv. "Grande Naine" (AAA) and Musa acuminata × balbisiana Colla cv. "Bluggoe" (ABB)-when these were fed on by the banana weevil (Cosmopolites sordidus (Germ.) (Coleoptera: Curculionidae)) and the banana stem weevil (Odoiporus longicollis (Oliver) (Coleoptera: Curculionidae)). The chemical constitue...

Sexual dimorphism in basitarsal pad morphology is described for prothoracic and mesothoracic legs ofDiabrotica virgifera virgiferaLeConte,Diabrotica barberiSmith&Lawrence, and Diabrotica undecimpunctata howardiBarber (Coleoptera: Chrysomelidae) and for prothoracic legs of Cerotoma trifurcata (Forster) (Coleoptera: Chrysomelidae). On the indicated legs of these diabroticite beetles, the typical ...
