Miroculis stenopterus, sp. nov., is described based on material from State of Pernambuco, Northeastern Brazil. The imago of the new species can be distinguished, among other characteristics, by an uncommon forewing shape, long and narrow, similar to species of genus Microphlebia. The tentatively associated nymph can be distinguished from other species of the genus mainly by the abdominal color ...

The collection of the immature stages of Dermacentor rhinocerinus from host animals is described for the first time. These are the bushveld gerbil (Tatera leucogaster, from which larvae and nymphs were collected, the red veld rat (Aethomys crysophilus), from which a larva was collected, and the Natal multimammate rat (Mastomys natalensis), from which a nymph was collected. The rodents were exam...

The frequency of pulsation of the intact heart in nymphs (final (?) instar) of Blatta orientalis L. increases with the temperature according to the equation of Arrhenius. The constant micro has typically the same value, within reasonable limits of error, as that (12,200) deduced for other, homologous activities of arthropods where the rate of central nervous discharge is perhaps the controlling...

Recent models from theoretical physics have predicted that mass-migrating animal groups may share group-level properties, irrespective of the type of animals in the group. One key prediction is that as the density of animals in the group increases, a rapid transition occurs from disordered movement of individuals within the group to highly aligned collective motion. Understanding such a transit...

The principal interactions leading to the emergence of order in swarms of marching locust nymphs was studied both experimentally, using small groups of marching locusts in the lab, and using computer simulations. We utilized a custom tracking algorithm to reveal fundamental animal-animal interactions leading to collective motion. Uncovering this behavior introduced a new agent-based modeling ap...

A print of Botticelli’s painting La Primavera in the dancer Isadora Duncan’s childhood home had a fundamental impact on her development modern dance. This article explores dance and costume based conjunction with other neo-Renaissance dancers (Sacharoff Sachetti) Aby Warburg’s interest Florentine nymph moving draperies, arguing for importance studying old masters, looking like woman, embracing ...

in this research, host stage preference of parasitoid wasp, aphidius matricariae haliday in choice and no-choice tests and functional response of the parasitoid were investigated on common wheat aphid, schizaphis graminum rondani on the alvand cultivar in laboratory conditions at 20, 25 and 30 °c, rh 70 ±10 % and a photoperiod of 16 h l : 8 h d. the maximum mean parasitisms in choice and no-cho...

We determined honeydew production by male and female sweetpotato whiteflies and the effects of temperature on honeydew production of each sex. We also determined honeydew production by each nymphal instar. Overall, adult SPW produced more honeydew than nymphs. Adult females produced more honeydew than males. The relative differences between honeydew production for males and females and between ...
