Abstract:The egg laying sites, pattern and the egg morphology (SEM) of an amblyceran louse parasitizing Bank Myna (Acridotheres ginginianus) have been recorded. Unlike most of the species of the genus, Menacanthus studied so far, the eggshell of M. eurysternus lacks the apophyses (bristle like outgrowths arising from anterior portion of the eggshell). However, the opercular disc of M. eurysternus bears a polar thread and the micropyles are set along the opercular rim.
:The egg chorion of the dog louse Heterodoxus spiniger bears pentagonal / rectangular scutes (scale like sculpturing) arranged obliquely. The opercular disc of the egg bears tall cup shaped micropyles which unite to give ridge like appearance. The centre of the disc bears short thick rod like polar thread.
Although at extreme energies (>50 TeV) -ray sources generally have large angular separations from one another as observed on Earth, at lower energies in the galactic plane this is often not the case. HAWC observes extended emission from the source eHWC J1850+001 exceeding 50 TeV, and at lower energies this region appears to consist of multiple sources of -ray emission. These include the 3HWC J1849+001 source but also two nearby H.E.S.S. sources observed in their Galactic Plane Survey. Therefore, a full description of the region requires a morphological study including the full energy range of HAWC data. Understanding the spatial features of the emission in this region is important to associate the sources observations at other wavelengths, which may point to hadronic or leptonic origins for the -ray emission. There are multiple pulsar wind nebulae and super nova remnant systems in the vicinity that may be responsible for the emission in this region, including the pulsar PSR J1849+001 and its pulsar wind nebula, which is a likely candidate for the >50 TeV energy emission seen by HAWC.
Three nymphal instars of bank Myna louse, Sturnidoecus bannoo differ from each other not only any size, abdominal segmentation, chitinization but also in the number of setae occurring on head, thorax and abdomen. Present report provides information on the diagnostic characters of three nymphal instars of the aforesaid louse.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
