How Firebrats (Thysanura: Lepismatidae) Detect and Nutritionally Benefit From Their Microbial SymbiontsEnterobacter cloacaeandMycotypha microspora

How firebrats (Thysanura: Lepismatidae) detect and nutritionally benefit from their microbial symbionts Enterobacter cloacae and Mycotypha microspora.

The phylogenetically ancient firebrats, Thermobia domestica (Packard) (Thysanura: Lepismatidae), lack any form of long-distance communication, yet are able to locate mates in sustained hot and humid microhabitats, typically within human habitations where they feed on dried goods, including cellulosic substrates. We have recently shown that firebrats aggregate in response to two symbiotic microo...

The effect of appendage and scale loss on instar duration in adult firebrats, Thermobia domestica (Thysanura).

The loss of appendages immediately following a moult shortens the subsequent intermoult interval in adult Thermobia domestica. The loss of increasing numbers of appendages accelerates the ensuing moult incrementally. Leg amputation at sites distal to the trochanter-femoral autotomy plane has comparable effects in accelerating the moult. Functional legs regenerated at the first moult following a...

Petri Nets and Bio-Modelling - and how to benefit from their synergy

Petri nets are a general, well-established model of concurrent and distributed computation featuring a wealth of tools for the analysis and verification of their behavioural properties. On the other hand, to understand specific biological processes different formalisations have been proposed. Examples here are membrane systems and reaction systems which are close abstractions of the functioning...

Contact toxicity and residual activity of different permethrin-based fabric impregnation methods for Aedes aegypti (Diptera: Culicidae), Ixodes ricinus (Acari: Ixodidae), and Lepisma saccharina (Thysanura: Lepismatidae).

The effectiveness and residual activities of permethrin-impregnated military battle dress uniforms were evaluated by comparing a new company-manufactured ready-to-use polymer-coating method with two "dipping methods" that are currently used to treat uniforms. Residual permethrin amounts and remaining contact toxicities on treated fabrics before and after up to 100 launderings were tested agains...
