By Bruno Corbara,Eric Darrouzet

Les insectes représentent environ 12 000 espèces, soit 2 % de l’entomodiversité, mais seventy five % de sa masse... et une biomasse considérable sur Terre. Pourtant, ils font partie des animaux les plus méconnus. Parmi eux, on distingue les insectes dits sociaux, qui constituent, sur l’échelle de l. a. socialité, le groupe de degré le plus élevé.

Abeilles, bourdons, guêpes, frelons, fourmis, termites vivent dans des sociétés à l’organisation complexe, et entretiennent des family avec un grand nombre d’êtres vivants : micro-organismes, champignons, plantes, autres animaux et bien sûr l’homme. Certaines de ces kinfolk sont caractérisées par des interactions inattendues : fourmis et termites hébergeant des champignons, fourmis élevant d’autres insectes, plantes nourrissant et abritant des fourmis qui les défendent des herbivores...

Ces sociétés nous fascinent par leurs performances collectives, l. a. diversité de leurs modes de conversation, los angeles flexibilité de leur répartition des fonctions individuelles. Pour communiquer, tous ces insectes usent de phéromones appropriées aux events d’exploration, de development, de défense de l. a. colonie, de recherche de nourriture ou de partenaires sexuels, et combinent souvent plusieurs sens pour transmettre des informations à leurs congénères, comme les abeilles dans leur fameuse « danse » associent des vibrations, des signaux visuels et des sons.

Ainsi les insectes sociaux réalisent-ils des activities remarquables : des fourmis chassent des animaux bien plus gros qu’elles, optimisent l. a. rapidité de leur trajet entre le nid et los angeles ressource alimentaire, termites et fourmis élaborent des nids dont l’ingénierie encourage nos propres architectes. Les capacités de coopération et même les comportements altruistes des membres pour l. a. sauvegarde de los angeles colonie fournissent des modèles d’intelligence collective à nos créations robotiques.Les insectes sociaux ne cessent de nous intriguer...

Download Bumblebees: Behaviour, Ecology, and Conservation by Dave Goulson PDF

By Dave Goulson

Bumblebees are widespread and charismatic bugs, happening all through a lot of the area. they're more and more getting used as a version organism for learning a variety of ecological and behavioural suggestions, comparable to social association, optimum foraging theories, host-parasite interactions, and pollination. lately they've got turn into a spotlight for conservationists as a result of mounting proof of diversity contractions and catastrophic extinctions with a few species disappearing from whole continents (e.g. in North America). simply through enhancing our knowing in their ecology do we devise good plans to preserve them. The function of bumblebees as invasive species (e.g. Bombus terrestris in Japan) has additionally develop into topical with the becoming alternate in advertisement bumblebee nests for tomato pollination resulting in institution of non-native bumblebees in a couple of countries.

Since the e-book of the 1st variation of the ebook, there were thousands of analysis papers released on bumblebees. there's in actual fact a continual want for an inexpensive, well-illustrated, and beautiful textual content that makes obtainable all the significant advances in figuring out of the behaviour and ecology of bumblebees which have been made within the final 30 years.

Download Honeybee Nests: Composition, Structure, Function by H.R. Hepburn,C.W.W. Pirk,O. Duangphakdee PDF

By H.R. Hepburn,C.W.W. Pirk,O. Duangphakdee

This paintings, a sequel to Honeybees and Wax released approximately 30 years in the past, starts off with a short creation and dialogue of nesting websites, their areas and densities, self-organization of nest contents, and interspecific usage of beeswax. the subsequent chapters hide conversation by way of vibrations and smells and wax secretion, and speak about the queen with regards to the combs. Discussions on accomplished nests comprise the importance of brood, the jobs of pollen and nectar move, and comb-building, and are by means of a triad of similar chapters at the building of cells and combs and their full of life expenses. An in-depth exam of the conversion of wax scales into combs, the fabric houses of scale and comb waxes, and the wax gland complicated are provided. the following chapters are dedicated to a accomplished research of the literature at the chemistry and synthesis of beeswax, and, eventually, the fabric houses of honeybee silk are highlighted.

By David Rentz

Cockroaches! Even an insignificant point out of the notice factors many of us to cringe in horror. even if, of the masses of species of cockroaches (or blattodeans as they're recognized) present in Australia, just a small variety of them supply the crowd a foul identify. quite a few species which are normally present in houses, eating places and hospitals are answerable for millions of bucks in expenditure to conform with overall healthiness standards.
A consultant to the Cockroaches of Australia is a entire account of many of the 550 defined species present in Australia. The publication finds their range and sweetness, it appears intimately at their morphology, habitats and ecology, and explains the right way to gather and safeguard them. Importantly, it's going to permit pest controllers, scholars and researchers to reliably determine lots of the universal pest species in addition to the non-pest cockroaches. it's going to additionally, might be, cross a way in the direction of raising the acceptance of those much-maligned bugs, and advertise additional research of them.
