The african Honey Bee
This book is the first review of the scientific literature on the Africanized honey bee. The African subspecies Apis mellifera scutellata (formerly adansonii) was introduced into South America in 1956 with the intent of cross-breeding it with other subspecies of bees already present in Brazil to obtain a honey bee better adapted to tropical conditions. Shortly after its introduction, some of the African stock became established in the feral population around Sao Paulo, Brazil, and spread rapidly through Brazil. It has since migrated through most of the neotropics, displacing and/or hybridizing with the previously imported subspecies of honey bees. Africanized bees have been stereotype d as having high rates of swarming and absconding, rapid colony growth, and fierce defensivebehavior. As they have spread through the neotropics they have interacted with the human population, disrupting apiculture and urban activities when high levels of defensive behavior are expressed.
Applied Myrmecology
Ants have always fascinated the nature observer. Reports from ancient Egypt and Mesopotamia indicate that ants interested humans long ago. Myrmecology as a science had its beginning in the last century with great naturalists like Andre, Darwin, Emery, Escherich, Fabre, Fields, Forel, Janet, Karawaiew, McCook, Mayr, Smith, Wasmann and Wheeler. They studied ants as an interesting biological phenomenon, with little thought of the possible beneficial or detrimental effects ants could have on human activities (see Wheeler 1910 as an example). When Europeans began colonizing the New World, serious ant problems occurred. The first reports of pest ants came from Spanish and Portuguese officials of the fifteenth and sixteenth centuries in Trinidad, The West Indies, Central America and South America. Leaf-cutting ants were blamed for making agricultural development almost impossible in many areas. These ants, Atta and Acromyrmex species, are undoubtedly the first ants identified as pests and may be considered to have initiated interest and research in applied myrmecology (Mariconi 1970).
Ant
Ants are legion: at present there are 11,006 species of ant known; they live everywhere in the world except the polar icecaps; and the combined weight of the ant population has been estimated to make up half the mass of all insects alive today. When we encounter them outdoors, ants fascinate us; discovered in our kitchen cupboards, they elicit horror and disgust. Charlotte Sleigh’s Ant elucidates the cultural reasons behind our varied reactions to these extraordinary insects, and considers the variety of responses that humans have expressed at different times and in different places to their intricate, miniature societies. Ants have figured as fantasy miniature armies, as models of good be...
