Observations on Forced Colony Emigration in Parachartergus Fraternus (Hymenoptera: Vespidae: Epiponini): New Nest Site Marked with Sprayed Venom

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Five cases of colony emigration induced by removal of nest envelope and combs and a single one by manipulation are described. The disturbance was followed by defensive patterns, buzz running, and adult dispersion. An odor trail created by abdomen dragging, probably depositing venom or Dufour’s gland secretions, connected the original nest to the newly selected nesting place and guided the emigration. The substrate of the selected nesting place is intensely sprayed with venom prior to emigration, and this chemical cue marked the emigration end point. The colony moves to the new site in a diffuse cloud with no temporary clusters formed along the odor trail. At the original nest, scouts performed rapid gaster dragging and intense mouth contacts stimulating inactive individuals to depart. Males were unable to follow the swarm. Individual scouts switched between different behavioral tasks before and after colony emigration. -

They lead a poorly known, secretive lifestyle, and Published 16 July 2015 may be more diverse than previously thought. We describe a new species from the high altitude forests of the Sorata massif in north Madagascar with unusual characteristics Academic editor: for this genus; R. longicrus sp. n. has long, slender legs, unlike most of its fossorial or Peter Bartsch semi-fossorial congeners. The new species is closely related to R. minuta, a much smaller frog from the Marojejy massif to the southeast of Sorata with similarly long legs. We discuss the morphology of these species relative to the rest of the genus, and argue that Key Words it suggests adaptation away from burrowing and toward a more saltatorial locomotion and an accordingly more terrestrial lifestyle. -

1 Exploring the male-induced female reproduction of Schistosoma mansoni in a novel medium Jipeng Wang1, Rui Chen1, James Collins1 1) UT Southwestern Medical Center. Schistosomiasis is a neglected tropical disease caused by schistosome parasites that infect over 200 million people. The prodigious egg output of these parasites is the sole driver of pathology due to infection. Female schistosomes rely on continuous pairing with male worms to fuel the maturation of their reproductive organs, yet our understanding of their sexual reproduction is limited because egg production is not sustained for more than a few days in vitro. Here, we explore the process of male-stimulated female maturation in our newly developed ABC169 medium and demonstrate that physical contact with a male worm, and not insemination, is sufficient to induce female development and the production of viable parthenogenetic haploid embryos. By performing an RNAi screen for genes whose expression was enriched in the female reproductive organs, we identify a single nuclear hormone receptor that is required for differentiation and maturation of germ line stem cells in female gonad. Furthermore, we screen genes in non-reproductive tissues that maybe involved in mediating cell signaling during the male-female interplay and identify a transcription factor gli1 whose knockdown prevents male worms from inducing the female sexual maturation while having no effect on male:female pairing. Using RNA-seq, we characterize the gene expression changes of male worms after gli1 knockdown as well as the female transcriptomic changes after pairing with gli1-knockdown males. We are currently exploring the downstream genes of this transcription factor that may mediate the male stimulus associated with pairing. -

E-mail: [email protected] Abstract Compsidolon Reuter from China with eleven species is reviewed here. Three of them, C. ailaoshanensis, C. flavidum, and C. pilosum are described as new to science. C. eximium (Reuter) is recorded from China for the first time. Compsidolon punctulatum Qi and Nonnaizab, 1995 is treated as a junior synonym of Compsidolon nebulosum (Reuter, 1878). A key to Chinese species of Compsidolon Reuter is given. Photographs of dorsal habitus, scanning electron micrographs of metathoracic scent-gland, and illustrations of male genitalia are also provided. All type specimens are deposited in the Institute of Entomology, Nankai University, Tianjin, China. Key words: Heteroptera, Miridae, Compsidolon, new species, new synonymy, China Introduction Reuter (1899) erected the monotypic genus Compsidolon to accommodate the type species, C. elegantulum from Syria. It was characterized by the dorsum covered with dark spots. Wagner (1965, 1975) presented keys to subgenera and species, and illustrated the male genitalia. His works were focused on the European fauna. Linnavuori (1992, 1993, 2010) recorded species from Greece, Middle East, and Africa. -
