Many praying mantis species remain known from type specimens only. The majority of these taxa have vague taxonomic limits, as original descriptions are often very short, making strong emphasis on superficial characters (Rivera 2010). One clear example of this is the Amazonian Mantellias Westwood, 1889, a monotypical genus represented by Mantellias pubicornis Westwood, 1889.
Abstract Rigorous species delimitation is a challenge in biology and systematics particular. In insects, male genitalia traditionally, the barcoding region of CO1 gene recently, are main markers to identify species, even though standalone use for that often criticized. our systematic revision mycophagous other ways peculiar oxyporine rove beetles Russia, legacy alpha-taxonomy could not be impro...
Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...
This paper reports on the first successful backcross breeding between TGGG hybrid grouper and GG in captivity. To establish a seed production technique for this new backcross grouper, eggs and larval development were observed. Three successful spawning was observed in November 2018, September 2019 and November 2019. The eggs were collected using stripping methods and the sperms were collected u...

The West Palaearctic genus Nothris is reviewed. Eight species are distinguished, and adults and genitalia are described and figured. Two species are described as new for science: Nothris gregerseni sp. n. and N. skyvai sp. n. New synonymies are established: Nothris discretella Rebel, 1889 syn. n. and N. verbascella clarella Amsel, 1935 stat. n. are considered synonyms of N. verbascella ([Denis ...
objective: the aim of this in vitro study was to compare the coronal microleakage between streptococcus sanguis per se and a mixture suspension of e. faecalis and c. albicans in root canals filled with gutta-percha and either ah 26 or ah plus sealer. materials and methods: one-hundred and ten extracted human teeth were decoronated to a standardized root length of 14 mm and prepared using mtwo n...
PURPOSE The use of tumor-derived proteins as cancer vaccines is complicated by tolerance to these self-antigens. Tolerance may be broken by immunization with activated, autologous, ex vivo generated and antigen-loaded, antigen-presenting cells (APC); however, targeting tumor antigen directly to APC in vivo would be a less complicated strategy. We wished to test whether targeted delivery of an o...
