Honey Production in Karak Pakistan
ISBN: 9783639357219 / Angielski / Miękka / 76 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The present study was conducted in Karak area to know about the average production of honey per colony. The minimum production of honey per colony was 2 kg while the maximum production of honey per colony was 20 kg in district Karak area. Four types of honey bees are found. These are Apis mellifera, A. dorseta, A. cerana and A. florae. The A. dorseta is the largest bee and black in color. The roduction of honey of this bee is good. They produce 30-40 kg of honey per colony in single year but the quality of the honey is inferior. The A. cerana commonly called Indian bee or khong bee, median in...

Ornithology
ISBN: 9783639358209 / Angielski / Miękka / 648 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Ornithology is the scientific study of birds. It is perhaps the only discipline in zoology that has benefited greatly from the contributions of amateurs. Much has been learned about the distribution, migratory movements, and ecology of birds from the observations of amateurs and such observations by ordinary people often have the advantage of being completely unbiased. This dictionary has been prepared as an aid for bird enthusiasts seeking definitions for unfamiliar terms or bird names that they may encounter in ornithological literature. It is a much enlarged and enhanced...

International Wildfowl Inquiry: Volume 1, Factors Affecting the General Status of Wild Geese and Wild Duck
ISBN: 9781107617483 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. During the century leading up to this book's publication in 1941, there had been a complete revolution in conditions governing the habits and numbers of wildfowl in many parts of the world. Industrial innovations such as the breech-loading gun, the steam-engine, and the internal combustion engine not only increased destruction, but, by disturbance of previously quiet resting places, led to vast changes in distribution. In most locations, these changes were masked by seasonal fluctuations, and too slow for the average wildfowler to notice. But it began to be realised, especially in North...

Among stored grain beetles Sitophilus oryzae is a serious insect pest of various food grains under storage.Tribolium castaneum is also a major cause of damage to stored grain.Wheat suffers heavy losses during storage due to insect pests. According FAO that loss done by annually by insects and rodent pests is 10 to 25% of world-harvested food. In Pakistan also about 2 to 6% food grain production is lost every year during storage by stored grain insect pests. Similarly the total post harvest loss of wheat is about 7.37% out of which 3.24% was due to stored grain insect pests. Weight loss of...

Insect Herbivore-Host Dynamics: Tree-Dwelling Aphids
ISBN: 9781107402638 / Angielski / Miękka / 208 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Designed to introduce students and research workers to insect herbivore-host dynamics, this book uses the interaction between aphids and trees as a model. Challenging the belief that population dynamics of insect herbivores are heavily influenced by the action of their natural enemies, it demonstrates that tree dwelling species of aphids actually regulate their own population through competition for resources.
