Zorotypus Hubbardi

For the first time, the karyotype is described in a representative of the order Zoraptera. Zorotypus hubbardi Caudell (Zorotypidae) have holokinetic chromosomes and male karotype of 2n = 38 (36 + neo-XY). Males possess two follicles in each testis and females have six panoistic ovarioles in each ovary. Oogenesis and, more closely, spermato genesis, including meiosis and sperm formation, have been studied. Based on the presence of panoistic ovaries and holokinetic chromosomes, Crampton's hypothesis that Zoraptera represent a group of Polyneoptera nearest to the origin of Paraneoptera is considered the most plausible.

Plant samples of Lepidium campestre (L.) W. T. Aiton (pepperwort) were analyzed in detail by GC and GC-MS. The analysis of the autolysates obtained from inflorescences, stems, leaves, and underground parts and the essential oil obtained by hydrodistillation allowed the identification of a series of glucosinolate degradation products, mainly isothiocyanates and nitriles. Besides previously identified ones in this species, the analyses resulted in the identification of degradation metabolites identified in pepperwort for the first time, and suggested the presence of heptyl glucosinolate, 3- phenylpropyl glucosinolate, glucoiberverin, glucoiberin, sinalbin, glucoerucin, glucoberteroin, gluconasturtiin, glucolepigramin, glucolesquerellin, glucobrassicanapin, and glucotropaeolin in this species as the most likely glucosinolate precursors. The results showed the localized accumulation of glucoberteroin, glucoerucin, and glucolesquerellin in the roots, the plant organ most exposed to pathogens, whereas sinalbin and glucobrassicanapin were accumulated in the reproductive organs and the organs most exposed to herbivores, i.e. in the aerial parts of the plant.

Abstract: Vulvovaginalis candidiasis (VVC) is a disease of female reproductive organs with the site of infection at the vulva and vagina mucosa characterized by vaginal discharge and itching due to the uncontrolled growth of the fungus Candida albicans. This study aimed to obtain the profile of vulvovaginalis candidiasis cases at Prof. Dr. R. D. Kandou Hospiptal Manado from January to December 2013. This was a retrospective descriptive study using the medical record. The results showed that of 29 VVC cases (0.70%), the largest age groups were 15-24 and 25-44 years (41.4%). Housewives and students were the most found jobs (20.7%). The discharge accompanied by itching was found in 34.5% of cases. The use of douching and pregnancy were predisposing factors (13.8%). Gram examinations resulted in spores, budding cell, and pseudohyphae were found in 62.1% of cases. Patients who was infected by VVC for the first time were 82.8%. The most frequent type of therapy was combination therapy (48.3%).

SynopsisAn account of the morphology of the external and internal reproductive organs of the females of Hapalemur and Lepilemur and of the male of Hapalemur, including some histological details in both sexes of Hapalemur, is presented. The female apparatus in Hapalemur is described here for the first time, while new concepts emerge in connection with the male genitalia of Hapalemur and the female organs of Lepilemur, both of which have been imperfectly known. The tunnelling of the large clitoris by the urethra in Hapalemur is unique among the Madagascar lemurs and parallels the condition in the suborder Lorisoidea. The female Lepilemur exhibits typically lemurine external and internal genitalia, but lacks the glandular specialisations met with in Lemur. Details of the relative positions and peritoneal relations of the uterine cornua and ovaries in different lemurine genera are discussed. In the male Hapalemur the penis agrees with that of other Lemurinæ; internally some observations of Beddard and Oudemans are confirmed and supplemented. The necessity for the taxoaomic separation of Hapalemur is considered.

Amerila is one of the most studied Afrotropical genera of Arctiinae. However, based on a regionally constrained sample of specimens from Mount Cameroon, we show how superficial our knowledge on these tiger moths is. Among six collected Amerila species, A. femina’s female is described here for the first time, and A. mulleri and A. roseomarginata had never been recorded before in the country. Moreover, novel biological data are presented, including individual species’ elevational ranges. Finally, female reproductive organs of the genus are illustrated here for the first time. The value of such regional studies is highlighted, with some remarks on necessary requirements of such small-scaled field sampling.

Abstract The establishment and maintenance of plant species in the Chaco, one of the widest continuous areas of forests in the South American with sharp climatic variations, are possibly related to biological features favoring plants with particular defenses. This study assesses the physical and chemical defenses mechanisms against herbivores of vegetative and reproductive organs. Its analyses of 12 species of Fabaceae (Leguminosae) collected in remnants of Brazilian Chaco shows that 75% present structural defense characters and 50% have chemical defense – defense proteins in their seeds, like protease inhibitors and lectins. Physical defenses occur mainly on branches (78% of the species), leaves (67%), and reproductive organs (56%). The most common physical characters are trichomes and thorns, whose color represents a cryptic character since it does not contrast with the other plant structures. Defense proteins occur in different concentrations and molecular weight classes in the seeds of most species. Protease inhibitors are reported for the first time in seeds of: Albizia niopoides, Anadenanthera colubrina, Mimosa glutinosa, Prosopis rubriflora, and Poincianella pluviosa. The occurrence of physical and chemical defenses in members of Fabaceae indicate no associations between defense characters in these plant species of the Chaco.

AbstractWithin Pollenia Robineau-Desvoidy a venturii species-group is defined and revised. It consists of a single species P. venturii Zumpt. P. solitaria Grunin is proposed as a junior synonym. It is characterized by unique features in the male aedeagus and the lateral sacs of the internal female reproductive organs. Male and female terminalia are illustrated, the latter for the first time. A preliminary cladistic analysis of all known Palaearctic species of Pollenia (except P. japonica Kano & Shinonaga) suggests that the sister-group of P. venturii is a clade consisting of the viatica + vagabunda + amentaria + haeretica species-groups. A sclerotized internal wall of the lateral sacs in the internal reproductive system of female Pollenia appears to be a parallelism developed independently in the venturii, rudis, most members of the tenuiforceps and some members of the semicinerea groups, rather than an underlying synapomorphy. P. venturii is known from France, Germany, Greece, Italy and Russia. A key is provided to species-groups in Pollenia.

The original description of this species was based on a single female and no illustrations of reproductive organs were presented. After we collected several specimens identified as I. seladonium, we decided to redescribe this species and discovered that the male, previously described as belonging to this species, was misidentified by MELLO LEITÃO (1923). Thus, in this paper the male of I. seladonium is newly described and the reproductive organs of male and female are described and illustrated in detail. Notes on the behavior and natural history of I. seladonium are presented based on the observation of live specimens in the field and in captivity. An immature of I. seladonium was observed constructing a hinged retreat with silk and little pieces of bark, a behavior not previously seen for other Aviculariinae. Two courtship events were observed and photographed, leg tapping and palpal drumming of the male on female's body and dorsum-ventral movements of the female's abdomen while the male was inserting the embolus were documented to Aviculariinae for the first time. The courtships and mating lasted almost two minutes.
