The present manuscript describes the use of silk cocoons as a structuring agent for formation an iron-based active phase controlled oxidation benzyl alcohol. Different samples were prepared using different calcination temperatures. X-ray diffraction and transmission electron microscopy showed higher proportion alpha-Fe2O3 global crystallinity at superior temperature. In terms catalytic activity...

Abstract The research is devoted to the study of genetic parameters a less studied trait - intensity egg laying on first day female silkworm butterflies. Based experiments conducted in promising lines Line 27 and 28, it was found that variability this Cv = 15,0-15,3%, heritability coefficient h2 0,321-0,340. Also, for time, close positive correlation established between leading reproductive sig...

Despite extensive research on mechanisms generating biases in sex ratios, the capacity of natural enemies to shift or further skew operational sex ratios following sex allocation and parental care remains largely unstudied in natural populations. Male cocoons of the sawfly Neodiprion abietis (Hymenoptera: Diprionidae) are consistently smaller than those of females, with very little overlap, and...

An insecticidal exclusion method was used to assess the effect of parasitoids on level of infestation by the diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), in cabbage. In field trials conducted at Rietondale, Pretoria, Gauteng Province and Brits, North-West Province, South Africa, a selective organophosphate pesticide, with systemic and contact action, dimethoate, ...

Significant accumulations of poultry droppings near large enterprises are a problem both in Ukraine and abroad. An urgent issue is the search for rational methods disposal these wastes with involvement natural, ecologically safe such as composting use microorganisms vermiculture. The during fermentation broiler chicken litter (in form sawdust non-coniferous trees) leads to reduction time prepar...
