Abstract Polyrhachis lamellidens is a temporary socially parasitic ant whose new queen utilizes other species in the early stages of colony foundation. Field observations and rearing experiments suggest that Camponotus japonicus host P. . It presumed obscuripes also by field observations; however, there are no records workers or brood coexisting C. colonies observations, clear evidence natural ...

Barfin flounder nervous necrosis virus (BFNNV), the causative agent of viral nervous necrosis (VNN) of barfin flounder, is vertically transmitted from spawners to larvae. In the present study, an ELISA with a recombinant protein of BFNNV was performed for the detection of antibodies against BFNNV and applied for the selection of brood fish in order to prevent viral vertical transmissions. Brood...

Caenorhabditis elegans is a model organism that has been used to study human bacterial and viral pathogenesis. We report here the expression of human hepatitis delta viral antigens (HDAg) in C. elegans and measure the effect on the sterility, growth, and brood size in transgenic worms. Expression of HDAg under two different promoters, fib-1 (a ubiquitous promoter) and myo-2 (a pharynx-specific ...

Mantispoidea exhibit a remarkably diverse morphology and life history for relatively small group of insects, in part, complicating our understanding its evolutionary history. Dietary specialisation the larvae, however, seems to have played an important role this group. Symphrasinae (Rhachiberothidae) larvae are thought be predators aculeate Hymenoptera brood, while Mantispinae (Mantispidae) spi...

Quantified amounts of Ascosphaera apis spores, causative organism ofchalkbrood disease, were cultured in vitro after being treated withtricloroisocianuric acid (TCA) (Yukoluck 93% a.i) inside honeybee colonies.This gaseous substance is registered in several countries for the control ofchalkbrood, a invasive mycosis affecting honeybee larvae. TCA acts, on thespores that are p...

Abstract The range of practical use bee products is constantly expanding. Among the large assortment these products, in recent years, drone brood larvae have received great attention, which can be obtained without harming colony during active period beekeeping season. Drone contains a complex biologically substances, including unique fatty acids, vitamins, essential amino steroid hormones. cont...
