Estimating the effect of tracking tag weight on insect movement using video analysis: A case study with a flightless orthopteran

In this study, we describe an inexpensive and rapid method of using video analysis and identity tracking to measure the effects of tag weight on insect movement. In a laboratory experiment, we assessed the tag weight and associated context-dependent effects on movement, choosing temperature as a factor known to affect insect movement and behavior. We recorded the movements of groups of flightless adult crickets Gryllus locorojo (Orthoptera:Gryllidae) as affected by no tag (control); by light, medium, or heavy tags (198.7, 549.2, and 758.6 mg, respectively); and by low, intermediate, or high temperatures (19.5, 24.0, and 28.3 degrees C, respectively). Each individual in each group was weighed before recording and was recorded for 3 consecutive days. The mean (+/- SD) tag mass expressed as a percentage of body mass before the first recording was 26.8 +/- 3.7% with light tags, 72 +/- 11.2% with medium tags, and 101.9 +/- 13.5% with heavy tags. We found that the influence of tag weight strongly depended on temperature, and that the negative effects on movement generally increased with tag weight. At the low temperature, nearly all movement properties were negatively influenced. At the intermediate and high temperatures, the light and medium tags did not affect any of the movement properties. The continuous 3-day tag load reduced the average movement speed only for crickets with heavy tags. Based on our results, we recommend that researchers consider or investigate the possible effects of tags before conducting any experiment with tags in order to avoid obtaining biased results.Web of Science167art. no. e025511

First record of Phormia regina (Meigen, 1826) (Diptera: Calliphoridae) from mummies at the Sant’Antonio Abate Cathedral of Castelsardo, Sardinia, Italy

The studies of insects from archaeological contexts can provide an important supplement of information to reconstruct past events, climate and environments. Furthermore, the list of the species present in an area in the past allows the reconstruction of the entomofauna on that area at that time, that can be different from the nowadays condition, providing information about biodiversity changes. In this work, the results of a funerary archaeoentomological study on samples collected from mummified corpses discovered during the restoration of the crypt of the Sant’Antonio Abate Cathedral of Castelsardo (Sardinia, Italy) are reported. The majority of the sampled specimens were Diptera puparia, whereas only few Lepidoptera cocoons and some Coleoptera fragments were isolated. Among Diptera, Calliphoridae puparia were identified as Phormia regina (Meigen, 1826) and Calliphora vicina, (RobineauDesvoidy, 1830) both species typical of the first colonization waves of exposed bodies. Three puparia fragments were also identified as belonging to a Sarcophaga Meigen, 1826, species (Sarcophagidae). Several Muscidae puparia of the species Hydrotaea capensis (Weidmermann, 1818), a late colonizer of bodies, and typical of buried bodies were also collected. The few moth (Lepidoptera) cocoons were identified as belonging to the family Tineidae. This family comprises species feeding on dry tissues and hair typical of the later phases of the human decomposition. Among Coleoptera a single specimen in the family Histeridae, Saprinus semistriatus(Scriba, 1790) and a single elytra, potentially of a species in the family Tenebrionidae, were also collected. Overall, the samples collected indicated an initial colonization of the bodies in an exposed context, mainly in a warm season. This research allows the finding of elements indicating the presence, at least in the past, of P. regina in Sardinia. This species at the moment seems extinct from Sardinia while it is quite common in the continent

Decomposition and Coleoptera succession on exposed carrion of small mammals

Abstract In 1997 and 1998, field studies on exposed rat carcasses were conducted in Opava, the Czech Republic, to describe the decomposition process and Coleoptera succession patterns. Coleoptera assemblages were monitored during three 40-d succession series conducted in spring, summer and autumn in two different habitats: meadow and deciduous forest. The rate of decomposition was studied in carcasses open to insects and isolated from them. The stages of decomposition recognised in this study follow Reed's classification: fresh, bloated, decay and dry stage. Carcass in summer decayed much faster than in spring and autumn and the decomposition of insect-free carcasses was less rapid than that of carcasses exposed to insects. A total of 145 Coleoptera species belonging to 22 families was recorded on the carcasses. The number of species in the succession series increased from the fresh stage, reached a maximum in the decay stage and gradually declined in the dry stage. The greatest diversity of Coleoptera was found in spring, followed by summer and autumn. More species were collected in forest site than in meadow. Four ecological groups, each characterised by a specific type of carrion association and varying in food specialisation and species biology, have been distinguished

Anisolabella planata sp. nov. differs from the other species of the genus Anisolabella based on the following combination of characteristics: the body is flattened with a noticeably flattened vertex of the head; antennomeres 2–22 are cylindrical, the distal antennomeres are long and thin, 6–7 times longer than wide; the right branch of the male forceps is widened interiorly in the distal quarter, and the abdominal tergites of male lack keels or ridges laterally; the penultimate sternite of male is narrowed posteriorly, with the posterior margin subtruncate and slightly emarginate. The parameres of the male genitalia are specific, oval, and broadened in the middle, 1.8 times longer than wide. It can be distinguished from the other Anisolabella species occurring on Socotra Island, A. haasi sp. nov., using the identification key below. Etymology. The Latin adjective, planatus (- a, -um; = flattened) is given in reference to the dorsoventrally flattened body of the new species, which is unusual in Anisolabella. Bionomy. Sifted from wet leaf litter in a montane evergreen woodland, association Leucado hagghierensi-Pittosporetum viridiflorum, see also the preceding species. Distribution. Yemen, Socotra Island (Fig. 27). Most likely an endemic species.Published as part of Kočárek, Petr, 2014, Earwigs (Dermaptera) of Socotra Island: checklist, distribution, and description of a new genus and four new species, pp. 1-21 in Acta Entomologica Musei Nationalis Pragae 54 on pages 9-11, DOI: 10.5281/zenodo.531235
