Comparisons of morphology and esterase levels between Blattella germanica and Blattella nipponica (Blattodea: Blattellidae)

Entomological Research, 2016
AbstractThe habitat of the cockroach varies by species. The German cockroach, Blattella germanica, lives in human dwellings, while the Japanese field roach, Blattella nipponica, lives in a mountainous region. Based on phylogenetic analysis of mtCOI, the two species are closely related to each other and B.

Ultrastructural investigation of the spore-forming protist Nephridiophaga blattellae in the Malpighian tubules of the German cockroach Blattella germanica

Parasitology Research, 1999
Multinuclear plasmodia of the sporogenic protist Nephridiophaga blattellae are found intracellularly and in the lumen of the Malpighian tubules of the German cockroach Blattella germanica. Spore formation occurs only in the lumen. During sporogony, about 10-35 spores measuring 5.5x3.2 microm are endogenously formed within a plasmodium.

Bacteriocyte population growth in Blattella germanica.

Journal of submicroscopic cytology and pathology, 2003
The number of bacteriocytes with nucleus in the M or S phase was analysed in relation to their rate of increase, throughout two nymphal instars (N1 and N6) of Blattella germanica Linnaeus (Blattaria, Blattellidae). We treated the experimental specimens with colcemid in order to visualize C-metaphases, and with labelled thymidine in order to evidence ...

[Genetic control of Blattella germanica].

Angewandte Parasitologie, 1978
Based on a literature survey, the possibilities of a genetic control of the German cockroach (Blattella germanica) are shown. First, an oversight is given on the cytogenetics of the German cockroach, including some important mutations. Then the control methods by genetic mechanisms are explained.

Identification of Blattella germanica piRNAs

2019
The Piwi-interacting RNA (piRNA) system is an evolutionarily conserved mechanism involved in the control of transposable elements and maintenance of genomic stability, especially in germ line cells and in early embryo stages. However, relevant particularities, both in mechanism and function, exist across species among metazoans and even within the ...

[German cockroaches (Blattella germanica) in a refrigerator].

Angewandte Parasitologie, 1980
German cockroaches (Blattella germanica) regularly occurred in a refrigerator of a hospital in Leipzig. Larvae of instars 1--6 of a population of high density but uneven spatial distribution infiltrated through the defective magnetic tape packing of the refrigerator door into an area maintaining +7...12 degrees C.
