The widespread use of synthetic chemical pesticides beginning in the late 1930s has contributed to development insecticide resistance many important species pest insects and plants. Recent trends pesticide have emphasized more environmentally benign control methods that take into consideration environmental, food safety, human health. Biopesticides (e.g., naturally occurring pesticidal compound...

Rabbits, like other animal species, are susceptible to infection with invasive and infectious diseases. Both ecto- endoparasites registered in them, including helminths, insects on the body, acarus scabies, protozoa. Rabbits characterized by a high degree of precocity, fecundity breadth use products obtained from them. As product rabbit breeding, first, meat is demand as dietary product. Part r...

background : appropriate methodology for storage biological materials, extraction of dna, and proper dna preservation is vital for studies involving genetic analysis of insects, bacteria, and reservoir hosts as well as for molecular diagnostics of pathogens carried by vectors and reservoirs. here we tried to evaluate the utility of a simple filter paper-based for storage of insects, bacteria, r...

In this work we define two kinds of crested product for reversible Markov chains, which naturally appear as a generalization of the case of crossed and nested product, as in association schemes theory, even if we do a construction that seems to be more general and simple. Although the crossed and nested product are inspired by the study of Gelfand pairs associated with the direct and the wreath...
