Infection of cat flea, Ctenocephalides felis, larvae by the entomophilic nematode Neoaplectana carpocapsae was accomplished in the laboratory. The Breton strain of N. carpocapsae provided higher larval mortality at lower dosages than did the DD-136 strain. Adult nematodes were evident in the insect hemocoel after 48 h; however, no infective third-stage larvae were produced. Larval flea infectio...

We present a galaxy evolution model which incorporates a physically motivated implementation of AGN feedback. Intermittent jets inflate cocoons of radio plasma which then expand supersonically, shock heating the ambient gas. The model reproduces observed star formation histories to the highest redshifts for which reliable data exists, as well as the observed galaxy colour bimodality. Intermitte...

Citizen science is a research approach that involves collaboration between professional scientists and non-professional volunteers. The utilisation of recent online citizen-science platforms (e.g. social networking services) has greatly revolutionised the accessibility biodiversity data by providing opportunities for connecting citizen worldwide. Meteorus stellatus Fujie, Shimizu & Maeto, 2...

Silk, seen as a material, is fiber made from silkworm cocoons and spiders. They have standard structural components hierarchical structures. Different manufacturing techniques allow obtaining silk in films, fibers, hydrogels, microspheres, sponges. We can tune the properties through structure of secondary proteins. The paper explores application biomedical, optics, electronic fields by analyzin...

There is a preponderance of evidence that the tussah silkmoth Antheraea pernyi was derived thousands of years ago from the wild A. roylei. Historical, sericultural, morphological, cytogenetic, and taxonomic data are cited in support of this hypothesis. This explains why A. pernyi is very easy to mass rear, produces copious quantities of silk in its cocoons, and the oak tasar “hybrid”crosses bet...

The purpose of this study is to develop and improve the technological process experimental technical means drying mulberry silkworm cocoons in an infrared (IR) unit, which can significantly speed up processing obtain a quality end product, as well reduce energy costs for drying. scientific novelty consists application vibration by radiation development generalized calculation such units. Our pr...

The evolution of cocoon care in Stegodyphus dumicola seems to be influenced by a high migration rate between the colonies. Intruding conspecifics are tolerated by resident spiders and discriminating behaviour is observed only under special conditions. To prevent social parasitism, females care only for their own cocoons and not for those of other females from the same or foreign colonies. I des...

In 2008-2009, we reared small ceraphronids (about 0.5 mm in body length) from cocoons that had been made possibly by two acarivorous species, Feltiella acarisuga (Vallot) and Feltiella acarivora (Zehntner) (Diptera: Cecidomyiidae) in Okinawa, Japan. Detailed morphological observation revealed that the ceraphronid was a new species of Aphanogmus Thomson (Hymenoptera: Ceraphronidae). We describe ...
