The insect!1 remain in symbiotic associations with a tremendous number of microorganisms, and some of them could be classified as parasitic/pathogenic. Without question, insect pathogens act as natural mortality agents and represent the third leg of the triad of biological control which is an environmentally sound alternative to chemical control. The virulence and pathogenicity of an insect parasite i. e. disease agent are determined by the microbial genome as a result of the coordinated expression of a concert of genes. These genes may be organized as cassettes and be associated with transmissible DNA. The acquisition of these domains or pathogenicity islands, may be sufficient to develop a...
Can we discover morality in nature? Flowers and Honeybees extends the considerable scientific knowledge of flowers and honeybees through a philosophical discussion of the origins of morality in nature. Flowering plants and honeybees form a social group where each requires the other. They do not intentionally harm each other, both reason, and they do not compete for commonly required resources. They also could not be more different. Flowering plants are rooted in the ground and have no brains. Mobile honeybees can communicate the location of flower resources to other workers. We can learn from a million-year-old social relationship how morality can be constructed and maintained over time.
Human population is growing rapidly, disproportionate to food supply, which necessitate production of more volume of food in the near future. The reliance on insecticides for quick and dramatic results was not totally free from adverse effects. This book intends to fill the gap by providing a critical analysis of different management strategies that have a bearing on agriculture, sustainability, and environmental protection. This book emphasizes the management strategies with evaluation of each strategy in the bigger picture of ecologically driven pest management. This book includes 24 chapters, which cover ecological and biorational basis of pest management, integrated pest and disease mana...
Tout le monde a, dans un recoin de sa mémoire, de vieilles questions qui traînent dans un tiroir obscur étiqueté « sciences ». Est-ce qu’un savon lave mieux s’il fait plus de bulles ? En quelle langue rêvent les sourds ? Qu’est-ce qui fait rougir les ronds de poêle ? Pourquoi ci ? Comment ça ? Mais par manque de temps pour chercher une réponse que l’on craint trop compliquée de toute façon, on les laisse s’empoussiérer pendant des années. Depuis 2006, les lecteurs du quotidien Le Soleil peuvent envoyer leurs questions à leur journal. Chaque dimanche, le journaliste scientifique Jean-François Cliche y répond dans la chronique Science au quotidien. La science, de votre sous-sol jusqu’aux étoiles fait le tour de plus de trois ans de réponses, d’une manière vivante et accessible, aux vraies questions du vrai monde.
