Abstract
This is the first report providing results on identification, cloning, and sequencing of extended fragments (5'-truncated copies) of R1 and R2 retrotransposons integrated into Blattella germanica genome. Comparative structural analysis of the received clones revealed two distinct subfamilies of R1 elements. However, all B. germanica R1 clones have two common features: poly(T) tails and similar target site duplications. Nucleotide structure and organization of five sequenced R2 fragments was similar. Analysis of R2 nucleotide sequences revealed typical deletions at the 3'end of target sites and lack of homopolynucleotides tails.

Abstract
Little information is available on genetic variation within and between populations of pest cockroaches. In this study, intraspecific HindIII polymorphism was investigated in the German cockroach, Blattella germanica (Linnaeus) (Dictyoptera, Blattaria: Blattellidae), using restriction fragment length polymorphisms (RFLP) of the non-transcribed spacer (NTS) region of ribosomal DNA (rDNA). Individual male insects were collected from infestations at three different pig farms. Each population was characterized by HindIII restriction fragment frequencies and haplotype (a particular X-chromosome pattern) frequencies. The inheritance of the X-chromosome HindIII rDNA patterns over 12 generations (3 years) follows Mendelian patterns, and the stability of this polymorphic marker indicates infrequent genetic recombination of variable sites. Although pairwise genetic distance measures were uncorrelated with geographical distance, the pattern of genetic differentiation of the three cockroach populations suggests that human-mediated transport of cockroaches is an important force in shaping the population genetic structure of cockroach infestations, at least at the regional scale of 10-100 km. Sequence variation in the ribosomal NTS is a useful marker, and RFLP of rDNA is a simple, robust and reproducible technique for differentiating recently diverged cockroach populations.

Abstract
A new DNA virus (Parvoviridae: Densovirinae, Densovirus) was isolated and purified from descendants of field-collected German cockroaches, Blattella germanica. Viral DNA and cockroach tissues infected with B. germanica densovirus (BgDNV) were examined by electron microscopy. Virus particles, about 20 nm in diameter, were observed both in the nucleus and in the cytoplasm of infected cells. Virus DNA proved to be a linear molecule of about 1.2 microm in length. BgDNV isolated from infected cockroaches infected successfully and could be maintained in BGE-2, a B. germanica cell line. The complete BgDNV genome was sequenced and analysed. Five open reading frames (ORFs) were detected in the 5335 nt sequence: two ORFS that were on one DNA strand encoded structural capsid proteins (69.7 and 24.8 kDa) and three ORFs that were on the other strand encoded non-structural proteins (60.2, 30.3 and 25.9 kDa). Three putative promoters and polyadenylation signals were identified. Structural analysis of the inverted terminal repeats revealed the presence of extended palindromes. The genome structure of BgDNV was compared with that of other members of the family Parvoviridae; the predicted amino acid sequences were aligned and subjected to phylogenetic analyses.

Abstract
Using polymerase chain reaction technique with primers flanking target sites of retrotransposons R1 and R2, integrated copies of these transposable elements were amplified in various cockroach species (Blattodea). It was shown that each species has a unique pattern of "5'-undertranscripts" with the definite set of amplified fragments of different lengths. Intraspecies polymorphism was revealed in analysis of German cockroach specimens obtained upon individual mating. This is the first report providing results of identifying, cloning, and sequencing extended fragments (5'-truncated copies) of Blatella germanica R1 and R2 retrotransposons. It may be assumed that patterns of 5'-truncated copies of R1 and R2 elements can be used as markers in population and phylogenetic studies. Moreover, cloned and sequenced fragments will be employed in our further studies for screening of the German cockroach genomic library in order to detect full-length copies in this class transposable elements.

Abstract
The polymorphism of nuclear ribosomal DNA has been studied in male German cockroaches. The RFLP analysis has been used to identify seven types of HindIII fragments, the variation of which may serve as the basis for the differentiation of laboratory strains with respect to some population indices, including the average number of fragments per animal (N), the proportion of polymorphic loci (P), and the average pairwise similarity (APS). The interpopulation variation (FST) calculated for nine haplotypes is 53.85%.

Abstract
Intergeneric, interspecific, and intraspecific genetic variation of the 310-bp 3'-end region of the mitochondrial gene of cytochrome oxidase I (COI) has been assessed in ladybirds (Coleoptera: Coccinnellidae). The phylogenetic distances between eight species of ladybirds have been determined. Mitochondrial DNA (mtDNA) nucleotide sequences have been compared in Adalia bipunctata L. differing in the elytron and pronotum colors that have been sampled from several geographically remote populations. The taxonomic statuses of two morphs from the genus Adalia, A. bipunctata bipunctata and A. bipunctata fasciatopunctata, have been identified.

Abstract
A new Blattella germanica densovirus (BgDNV, Parvoviridae: Densovirinae, Densovirus) was found. Virus DNA and cockroach tissues infected with BgDNV were examined by electron microscopy. Virus particles about 20 nm in diameter were observed both in the nucleus and in the cytoplasm of infected cells. Virus DNA proved to be a linear molecule sized about 1.2 microns. The complete BgDNV genome was sequenced and analyzed. Five ORF were detected: two coded for structural capsid proteins and were on one DNA strand, and three coded for regulatory proteins and were on the other strand. Potential promoters and polyadenylation signals were identified. Structural analysis was performed for terminal inverted repeats containing extended palindromes. The genome structure of BgDNV was compared with that of other Parvoviridae.

Abstract
Species-specific characteristics of nuclear ribosomal DNA (rDNA) have been determined for the first time for six insect species of order Blattaria (Insecta, Dictyoptera) with the use of restriction analysis and Southern blotting. Probes containing highly conserved fragments of 18 S- and 28 S-like genes of the ribosomal RNA (rRNA) of Tetrahymena pyriformis were tested in this study. The genetic similarity tree constructed for the species studied agrees with evidence from classical taxonomy based on morphological, ecological, anatomical, and physiological characters.

Abstract
Conservatism of primary and secondary structure of osteopontin mRNA in vertebrates of various taxes was studied using computer analysis and blot-hybridization procedure. Relatively high rate of evolution of a nucleotide sequence of osteopontin gene was revealed. Formation of hairpin-loop structures by adjacent sequences and a high content of AU-pairs indicate more flexible structure of the mammalian osteopontin mRNA as compared with the avian one. It has been detected some AU-enriched regions in 3'-terminal untranslated sequences, which presence is characteristic for short-lived mRNA. Evolutionary conserved subsequences in 3'- and 5'-terminal regions were suggested to be determinants of RNA-protein interaction in cytoplasm.

Abstract
HindIII restriction digests of the rDNA repeat unit of the German cockroach, Blattella germanica, reveal significant intraspecies sequence polymorphism. This variability is probably caused by structural differences within the nontranscribed spacer regions (NTS) of the ribosomal repeat unit. HindIII rDNA fragment polymorphisms in three cockroach strains show that individuals from different populations may have different HindIII rDNA patterns, whereas individuals within populations exhibit relatively similar rDNA patterns. We suggest that HindIII restriction fragment polymorphisms within cockroach ribosomal DNA will be a valuable tool for measuring population-level parameters within and between natural cockroach populations.
