Modeling Currents About Vitellogenic Oocytes of the Cockroach, Blattella germanica.
An insect oocyte with a disc-shaped sink of current on its ventral surface during a vitellogenic phase of development is used to demonstrate modeling of expected currents arising from a mathematically defined source. A simple model with an analytical solution for the expected currents is compared to a more complex model in which expectations are computed by mathematical integration. The current...
متن کاملDe Novo Transcriptome of the Hemimetabolous German Cockroach (Blattella germanica)
BACKGROUND The German cockroach, Blattella germanica, is an important insect pest that transmits various pathogens mechanically and causes severe allergic diseases. This insect has long served as a model system for studies of insect biology, physiology and ecology. However, the lack of genome or transcriptome information heavily hinder our further understanding about the German cockroach in eve...
متن کاملThe cDNA for leucomyosuppressin in Blattella germanica and molecular evolution of insect myosuppressins.
Myosuppressins are a group of 10-residues FMRFamide-related peptides reported in Dictyoptera, Orthoptera, Lepidoptera and Diptera. Myosuppressins inhibit visceral muscle contractions and, in the cockroach Blattella germanica, inhibit food intake. In B. germanica, the cDNA of leucomyosuppressin (LMS) has been cloned and sequenced. The deduced precursor is 96 amino acids long and contains a singl...
متن کاملCuticular hydrocarbons as maternal provisions in embryos and nymphs of the cockroach Blattella germanica.
Cuticular hydrocarbons of arthropods serve multiple functions, including as barriers to water loss and as pheromones and pheromone precursors. In the oviparous German cockroach, Blattella germanica, long-chain hydrocarbons are produced by oenocytes within the abdominal integument and are transported by a blood lipoprotein, lipophorin, both to the cuticular surface and into vitellogenic oocytes....
متن کاملOrigin and extent of resistance to fipronil in the German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae).
Fipronil, a phenylpyrazole insecticide, was made available in 1999 in bait formulations for use against the German cockroach, Blattella germanica (L.). We have investigated resistance to fipronil in the descendants of cockroaches collected just before, or contemporaneously with, the introduction of fipronil baits. Cockroaches were obtained in two types of settings: homes that either had or had ...
