Large numbers of a cockroach that resembled the German cockroach, Blattella germanica (L.), were observed duringwinter 2005Ð2006 in home turf settings inWeslaco, TX, 11 km from theU.S. borderwith northeasternMexico. In June and July 2006, this cockroachwas observed at night on the foliage of soybean,Glycine max (L.)Merr., in numbers often exceeding 50 per m row. Because of its similarity to B. ...

Myers, Aaron J. M.S., Purdue University, May 2015. Identification, description, and activity of proteins in the tergal glands of the German cockroach, Blattella germanica (L.). Major Professors: Gary Bennett and Mike Scharf. German cockroaches are important urban pests that have been linked to asthma and serious allergic reactions in sensitized individuals. In this research project I, (i) ident...

Yanlin Tian. M.S., Purdue University, May 2015. Potential of ozone technology for german cockroach (Blattella germanica (L.)) management. Major Professors: Linda J Mason and Ameya D Gondhalekar. German cockroaches (Blattella germanica (L.)) are important urban pests that adversely impact human health. Previous studies indicated that ozone technology (ozone gas) can be used as a management tool ...

BACKGROUND FoxO proteins are a subgroup of the Forkhead-box family of transcription factors, which function as the main transcriptional effectors of the insulin receptor pathway. This pathway, activated by the binding of insulin or IGFs (or insect insulin-like peptides), promotes the phosphorylation and inactivation of FoxO because of its export from the nucleus to the cytoplasm. The homolog of...

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...

The German cockroach, Blattella germanica (Linnaeus) (Dictyoptera: Blattellidae), produces several potent human allergens, one of which, Blattella germanica allergen 1 (Bla g 1), is produced in the midgut and excreted in faeces. We tested with descriptive and experimental approaches the hypothesis that Bla g 1 production is related to food intake in adult males and females of the German cockroa...

Members of the morphologically and ecologically diverse Blattellidae provide a dilemma: their systematic assignment, whether similar or different, is uncertain. We pay special attention to several taxa: Episymploce Bey-Bienko, 1950 Symploce Hebard, 1916, which were strongly disputed because extremely generic diagnosis in past century, one brachypterous species Blattella Caudell, 1903, can be ea...
