Linalool is a natural plant-product used in perfumes, cosmetics, and flavoring agents. Linalool has proven antimicrobial and insect-repellent properties, which indicate it might be useful for control of enteropathogens or insect pests in poultry production. However, there are no published reports that linalool may be safely administered to or tolerated by chickens. Linalool was added to the die...

We have isolated mini-titin from the nematodes Ascaris lumbricoides and Caenorhabditis elegans under native conditions using a modification in the procedure to prepare this protein from insect muscle. The proteins have an apparent molecular weight of 600,000 and appear in oriented specimens as flexible thin rods with a length around 240-250 nm. The circular dichroism spectrum of the Ascaris pro...

background: rotaviruses cause diarrhea in infants and young children worldwide. rotavirus outer capsid protein, vp7 is major neutralizing antigen that is important component of subunit vaccine to prevent rotavirus infection. many efforts have been done to produce recombinant vp7 that maintain native characteristics. we used baculovirus expression system to produce rotavirus vp7 protein and to s...

An alternative to fumigants and insecticides for controlling stored-product insects in empty grain storage bins prior to filling is heat treatment, in which the temperature is quickly raised to a minimum of 50 1C and held there for 2–4 h. Effectiveness of heat treatment on empty grain storage bins was evaluated for five commercial propane and electric heat-treatment systems by measuring air tem...

A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of 2006. The hybrids were evaluated for resistance to the C. partellus and B. fusca, and for agronomic performance over two seasons during long and short rains of 2007 at a mid-alti...

Most homeowners have little knowledge of these troublesome insects and what it takes to get rid of them. Our understanding of termites has progressed considerably in recent years. New management tools including the use of baits have begun to emerge. As more termite control companies begin to offer baiting as an option, homeowners will have many questions. This publication will help homeowners m...

The innate immune system is an ancient component of host defense. Since innate immunity pathways are well conserved throughout many eukaryotes, immune genes in model animals can be used to putatively identify homologous genes in newly sequenced genomes of non-model organisms. With the initiation of the "i5k" project, which aims to sequence 5,000 insect genomes by 2016, many novel insect genomes...

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...
