Morphology of the Female Reproductive System of the Soybean Thrips, (Beach, 1896) (Thysanoptera: Thripidae).

Soybean thrips () are an important phytophagous vector of the widely recognized Soybean vein necrosis orthotospovirus (SVNV). Understanding the egg-laying behavior of these thrips could aid in developing strategies for the management of the vector and virus. In this study, we described the egg-laying behavior of and reconstructed the three-dimensional morphology of the female terminalia by using serial block-face scanning electron microscopy (SBFSEM) and confocal laser scanning microscopy (CLSM).

Taxonomic description and phylogenetic placement of two new species of (Hymenoptera: Pteromalidae: Ceinae) from Eocene Baltic amber.

is a small genus of chalcid wasps that has received little attention despite the widespread distribution of its extant species. The fossil record of the genus is restricted to a single species from Miocene Dominican amber. We describe two new fossil species, sp.

Giant polyploid epidermal cells and male pheromone production in the tephritid fruit fly Eurosta solidaginis (Diptera: Tephritidae).

Eurosta solidaginis males produce large amounts of putative sex pheromone compared to other insect species; however, neither the site of pheromone production nor the release mechanism has been characterized. We compared E. solidaginis males and females, focusing on sexually dimorphic structures that are known to be involved in pheromone production in other tephritid species.

Insect morphometry is reproducible under average investigation standards.

Morphometric research is being applied to a growing number and variety of organisms. Discoveries achieved via morphometric approaches are often considered highly transferable, in contrast to the tacit and idiosyncratic interpretation of discrete character states. The reliability of morphometric workflows in insect systematics has never been a subject of focused research, but such studies are sorely needed.

A catalogue of the tribe Sepidiini Eschscholtz, 1829 (Tenebrionidae, Pimeliinae) of the world.

This catalogue includes all valid family-group (six subtribes), genus-group (55 genera, 33 subgenera), and species-group names (1009 species and subspecies) of Sepidiini darkling beetles (Coleoptera: Tenebrionidae: Pimeliinae), and their available synonyms. For each name, the author, year, and page number of the description are provided, with additional information (e.g.

A new megaspilid wasp from Eocene Baltic amber (Hymenoptera: Ceraphronoidea), with notes on two non-ceraphronoid families: Radiophronidae and Stigmaphronidae.

Ceraphronoids are some of the most commonly collected hymenopterans, yet they remain rare in the fossil record. Mikó and Trietsch, sp. nov.

(Hymenoptera: Ceraphronidae), a new species from Lower Saxony with unusual male genitalia.

Background: Male genitalia phenotypes of (Jurine, 1807) are informative for species delimitation, but due to their minute size, these characters have not been used extensively. Recent developments in visualisation techniques, confocal laser scanning microscopy and high resolution bright field imaging, allow for more thorough examination of these minute anatomical structures and the development of a robust, male genitalia-based taxonomic system. We also establish a character set, a template, that will facilitate future revisions of these wasps.
