“…The co-infestation of a single host by Tropilaelaps and Varroa is rare, an observation also reported by Ritter and SchneiderRitter (1988) and Burgett et al (1989) with the Acarapis species complex. In general, insect frass and its volatile components provide cues in habitat location (Weiss 2006). In this study, avoidance of an infested cell may be one of the reasons for such a low mixedgenera infestation.…”

Prevalence and reproduction of Tropilaelaps mercedesae and Varroa destructor in concurrently infested Apis mellifera colonies

et al. 2015

-The prevalence of Tropilaelaps mercedesae and Varroa destructor in concurrently infested A. mellifera colonies in Thailand was monitored. We also assessed the fecundity of T. mercedesae and V. destructor in naturally infested brood and in brood cells deliberately infested with both mite genera. Results showed that the natural co-infestation of an individual brood cell by both mite genera was rare (<0.1 %). Overall, T. mercedesae was the more dominant brood parasite of A. mellifera than V. destructor. In naturally infested brood, the proportion of nonreproductive Tropilaelaps (29.8±3.9 %) was lower than that of Varroa (49.6±5.9 %). Both mites produced similar numbers of progeny (T. mercedesae =1.48±0.05; V. destructor =1.69±0.14). The two mite genera also reproduced normally when they were deliberately introduced into the same brood cells. In two separate assessments, the average worker brood infestations of T. mercedesae (19.9 %) were significantly higher than that of V. destructor (0.7 %). Our results on the higher prevalence and reproductive ability of T. mercedesae in concurrently infested colonies reaffirm Tropilaelaps ' competitive advantage over V. destructor and their reported negative impact to A. mellifera colonies.Apis mellifera / Tropilaelaps mercedesae / Varroa destructor / concurrent infestation / seasonal abundance

Crime scene and body alterations caused by arthropods: implications in death investigation

et al. 2018

View full text Add to dashboard Cite

The activity of arthropods on corpses has been largely investigated, since they can produce information to reconstruct the perimortem events. However, the feeding/movement activity of insects around the crime scene, among the clothes and on the body, can also cause some alterations that can lead to wrong reconstruction and misinterpretations. This article summarises all the postmortem arthropods artefacts related to the scene (i.e. fly artefacts and floor stripes) and the body (i.e. skin and other soft tissue alterations, bone alterations and hair alterations) that can mislead the forensic pathologist, discussing macroscopic and microscopic findings derived from forensic casework and from experimental laboratory studies, in order to provide a useful instrument to avoid misinterpretations and evaluation errors. Finally, some procedural notes for the documentation and the interpretation of findings are proposed.

“…Sap-sucking hemipterans display diverse protective mechanisms against harmful contacts with their sticky exudates [9]. Forceful shooting of exudates away from the body is widespread, but it does not protect either from discharges of other individuals or from getting stuck to contaminated plant surfaces.…”

Brochosomes protect leafhoppers (Insecta, Hemiptera, Cicadellidae) from sticky exudates

Leafhoppers (Insecta, Hemiptera, Cicadellidae) actively coat their integuments with buckyball-shaped submicron proteinaceous secretory particles, called brochosomes. Here, we demonstrate that brochosomal coats, recently shown to be superhydrophobic, act as non-stick coatings and protect leafhoppers from contamination with their own sticky exudates-filtered plant sap. We exposed 137 wings of Alnetoidia alneti (Dahlbom), from half of which brochosomes were removed, to the rain of exudates under a colony of live A. alneti. One hundred and fifty-two droplets became stuck to the bared wings and only three to the intact wings. Inspection of the wings with a scanning electron microscope confirmed that the droplets that had hit the intact wings had rolled or bounced off the brochosomal coats. This is the first experimental study that tested a biological function of the brochosomal coats of leafhopper integuments. We argue that the production of brochosomes in leafhoppers and production of epidermal wax blooms in other sap-sucking hemipterans are alternative solutions, both serving to protect these insects from entrapment by their exudates.
