This article presents the results of research to determine main technical and economic indicators a new installation we have created for marinating cocoons with help solar radiation energy. The possibility both on sunny cloudy days has been proven through direct indirect use energy radiation. performance installation, temperature inside drying chamber time complete were determined. On basis dat...

Last instar larva and pupa of Metadonus vuillefroyanus (Capiomont, 1868) (Curculionidae: Hyperini) are described and compared with known larvae of the other 43 hyperine taxa. The thorn-like setae located on distinct black protuberances on the larval body are characteristic features of the genus Metadonus and the subgenus Eririnomorphus of the genus Hypera. The biological singularity of this spe...

Fig. 1 Gonometa postica: Moth, opened and entire cocoon. from rumen impaction in the North-Western Cape. Similar losses, reported by Edwards I from the Northern Transvaal in 1935, were caused by cocoons of the moth Gonometa rufubrennea. A related moth of the same genus, Gonometa postica (Walker) (fig. 1) occurs in the North-Western Cape, namely north of an imaginary line drawn from Mafeking to ...

We estimate the deformation of the cosmic microwave background radiation by the hot region (“cocoon”) around a radio galaxy. A simple model by is adopted for cocoon evolution while the jet is on, and a model of evolution is constructed after the jet is off. It is found that at low redshift the phase after the jet is off is longer than the lifetime of the jets. The Compton y parameter generated ...

At the global level, special attention is paid to care of mulberry silkworm Bombyx mori L. in different climatic conditions, adaptation monovoltine breeds and hybrids ecological regions, production high-quality raw silk that meets requirements international standard 2A, 3A, 4A. being directed. Today, creating a new generation improving technological properties cocoons materials obtained from th...

In this paper we compute the luminosity function of radio relics. In our calculation we include only those relics that are produced by the compression of former radio cocoons. This compression is provided by shocks that are generated in the process of structure formation. Starting from an analytical model for the luminosity evolution of ageing radio cocoons, the luminosity function of radio gal...

Laboratory tests with Diadegma insulare (Cresson), a parasitoid of the diamondback moth ( Plutella xylostella (L.)), were conducted to evaluate the viability of cocoons stored at 4 ° C for varying lengths of time and also the effects of parasitism by D. insulare on the feeding rate of diamondback moth larvae. The percentage of adults emerging from cocoons declined steadily with time spent in st...

The objective of the present study was to adapt techniques for the histological processing of Dugesiidae cocoons for the study of embryo development. The cocoons were fixed with formalin, SUSA, Bouin or paraformaldehyde/glutaraldehyde and subsequently embedded in Paraplast or glycol methacrylate (Historesin). Paraplast embedding yielded reasonable results only after the cocoon was perforated or...

Predators exert strong top-down pressure on herbivorous insects, but research on how predators affect herbivore fitness often focuses on the more active juvenile and adult life stages while ignoring the pupal or cocoon life stage. Few studies have investigated predation of lepidopteran pupae or cocoons and even fewer have investigated species that are not forest pests. Here we present a study o...

Wild Silkmoth cocoons are difficult or impossible to reel under conditions that work well for cocoons of the Mulberry silkmoth, Bombyx mori . Here we report evidence that this is caused by mineral reinforcement of Wild Silkmoth cocoons and that washing these minerals out allows for the reeling of commercial lengths of good quality fibers with implications for the development of the "Wild Silk" ...
