Madagascar Hissing Cockroach hemolymph PO2, PCO2, and gas exchange parameters
<p>This data set contains <em>in vivo </em>measurements of<em> </em>hemolymph PO<sub>2</sub> and PCO<sub>2</sub> made on Madagascar hissing cockroaches (<em>Gromphadorhina portentosa</em>) using implanted micro fiber optic sensors (optodes). In addition, rate of CO<sub>2</sub> release, ventilation frequency, and durations of the tri-phasic discontinuous gas exchange cycle associated with these measurements are also recorded. All measurements were performed while the cockroaches were breathing either normoxic and normocapnic air, hypoxic air (10 kPa PO<sub>2</sub>), or hypercapnic air (2 kPa PCO<sub>2</sub>) at 22 ºC.</p>
Ventilatory parameters measured in Madagascar hissing cockroaches during continuous gas exchange and DGCs
<p>This dataset is presented in the manuscript titled: 'Discontinuous gas exchange in Madagascar hissing cockroaches is not a consequence of hysteresis around a fixed PCO<sub>2</sub> threshold'; published in JEB. The primary purpose of this investigation was to test if discontinuous gas exchange cycles (DGCs) were caused by PCO<sub>2</sub> fluctuations around ventilatory setpoints. Madagascar hissing cockroaches were exposed to normoxic acapnia and treatments of either hypoxic acapnia, and normoxic hypercapnia, while displaying continious gas exchange, and DGCs. Hemolymph PO<sub>2 </sub>and PCO<sub>2</sub> were measured in conjunction with ventilatory frequency and VCO<sub>2 </sub>released. This data displays the changes in ventilatory parameters observed during ambient gas manipulations.</p>
Figure 1 in DNA barcoding and coalescent-based delimitation of endosymbiotic clevelandellid ciliates (Ciliophora: Clevelandellida): a shift to molecular taxonomy in the inventory of ciliate diversity in panesthiine cockroaches
Figure 1. Phylogenetic tree based on the 18S rRNA gene, ITS1-5.8S-ITS2 region and 28S rRNA gene, showing relationships among ciliates isolated from the digestive tract of panesthiine cockroaches. All tree-building methods resulted in very similar topologies. The single exception is the Anteclevelandella constricta cluster, where the IQTree topology differs from that of both Bayesian trees (shown in the box). Bootstrap values for the maximum likelihood conducted in IQTrees and posterior probabilities for Bayesian inferences conducted in MrBayes and Phycas are listed at corresponding nodes of the best scoring IQTree. Specimen codes and further details are listed in Table 1. The scale bar denotes two substitutions per one hundred nucleotide positions.

Figure 4. Consensus secondary structure of the ITS2 molecule of 54 members of the order Clevelandellida isolated from the digestive tract of cockroaches. Note that the central loop radiates four highly conserved helices. The structure logo of helices is shown on the right side. The height of a base is proportional to its frequency in the multiple sequence alignment.
Figure 3 in DNA barcoding and coalescent-based delimitation of endosymbiotic clevelandellid ciliates (Ciliophora: Clevelandellida): a shift to molecular taxonomy in the inventory of ciliate diversity in panesthiine cockroaches
Figure 3. MDS diagrams (A, C, E) and TCS networks (B, D, F) based on 18S rRNA gene (A, B), ITS1-5.8S-ITS2 region (C, D) and 28S rRNA gene (E, F) sequences of the family Clevelandellidae. The MDS diagrams show the distribution of specimens in the genotype space. Species belonging to the same genus form a cluster distinctly isolated from other such clusters. The TCS networks reflect the most parsimonious relationships among species given the individual markers. Numbers along edges indicate mutational steps between adjacent nodes. Species belonging to the same genus are marked by the same colour code.

The TCS network reflects the most parsimonious relationships among species given the concatenated dataset. Numbers along edges indicate mutational steps between adjacent nodes. Species belonging to the same genus are marked by the same colour code.

Diet nutritional condition affects tergal gland secretion and courtship success of male cockroaches
<p>An integral part of the courtship sequence of the German cockroach (<em>Blattella germanica</em>) involves the male raising his wings to expose tergal glands on his dorsum. When a female cockroach feeds on the secretion of these glands, she is optimally positioned for mating. Core chemical components have been identified, but the effect of male diet on the tergal gland secretion remains unexplored. After validating the pivotal role of tergal feeding in mating, we starved or fed reproductively mature males for one week. We then paired each male with a sexually receptive female and observed their interactions through an infrared-sensitive camera. While starvation had no effect on male courtship behavior, it did influence the duration of female tergal feeding and mating outcomes. Females fed longer on the gland secretion of fed males, and fed males experienced greater mating success than starved males (73.9% vs. 48.3%, respectively). These results suggest that the quality of the tergal gland secretions, and by association mating success, are dependent on the nutritional condition of the male.</p>

FIGURE 7 in Morphological and molecular characterization of two species of nematodes (Oxyuridomorpha: Thelastomatoidea: Protrelloididae, Thelastomatidae) parasitic in the cockroach Blaberus discoidalis Serville (Blattaria: Blaberidae) from Cuba
FIGURE 7. Maximum likelihood (ML) tree inferred from the D2-D3 28S rDNA for several species of the family Thelastomatidae and Protrelloididae (Nematoda: Oxyuridomorpha). Since the topology of both the ML and BI phylograms was similar only the former is shown. Three species of Pseudonymidae and two of Travassosinematidae were used as outgroup taxa. Values at the nodes correspond to bootstrap resampling (≥70)/posterior probability (≥0.90). Newly obtained sequences in bold. The species Severianoia blapticola Guzeeva, 2009 was considered species inquirenda by Malysheva et al. (2020). However, the sequence under the accession number EU365631 and identified as the aforementioned taxon was included in the present analyses. The goal of the latter was to use sequences of all the available taxa of Thelastomatidae and Protrelloididae in the study.
