Oxazosulfyl is the first representative of a novel sulfyl class insecticides with potent and cross-spectrum insecticidal activity, albeit an unclear mechanism action. As potential agent pest control in rice fields, we investigated action oxazosulfyl on nervous system voltage-gated sodium channels insects. After injection 10 μg oxazosulfyl, American cockroaches (Periplaneta americana) were quick...

Boric acid dust treatments were evaluated as a tool for the integrated management of the German cockroach, Blattella germanica (L.), in commercial confined swine production. The efficacy of boric acid dust was comparable to that of an organic residual insecticide, cyfluthrin, which is commonly used to control cockroaches in this environment. Fall treatments suppressed the cockroach population f...

Secondary kill of the German cockroach, Blattella germanica (L)., by baits was reported to increase the overall control efficacy of bait products. However, most studies have been based on laboratory strains and small nymphs. We compared the secondary kill of four cockroach gel baits against various developmental stages of a laboratory (Jwax) and a field (Dorie) strain B. germanica. The four bai...

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...

Aquaporins (AQPs) are membrane proteins that form water channels, allowing rapid movement of water across cell membranes. AQPs have been reported in species of all life kingdoms and in almost all tissues, but little is known about them in insects. Our purpose was to explore the occurrence of AQPs in the ovary of the phylogenetically basal insect Blattella germanica (L.) and to study their possi...

Cockroaches are claimed to be mechanical transmitters of disease causing microorganisms such as intestinal parasites, bacteria, fungi, and viruses. This study assessed the potential of the German cockroach Blattella germanica in the mechanical transmission of intestinal parasites of public health importance. A total of 2010 cockroaches were collected from 404 households in Jimma Town, southwest...
