The loss of the olive crop due to the damage inflicted mainly by Dacus oleae (Insecta, diptera), range from 10 to 70%. According to FAO the loss annually by insects and rodent pests is 10 to 25% of world harvested food. In Pakistan, fruit flies cause a loss of around Rs.7 million annually. While according to another report, in Pakistan about 2 - 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. Therefore, the control of these flies and other insect pests is an important health concern. Flies and mosquitoes (Dipterans species) constitute two major groups of nuisance species in rural and urban environments and remains a major source of illness and death worldwide. Mosquitoes alone transmit disease to more than 700 million people annually. This can be valuable book for agriculturist, planners and allied stalk holders. ····· 1036198851

It is usually recognized as a result of the abnormal secretion of insulin by pancreatic -cells, inability of the insulin to stimulate the peripheral utilization (muscles and adipocytes) and increased endogenous glucose production by liver. DM is classified as Type 1 and Type 2 diabetes. The cause of the Type 1 diabetes mellitus has been attributed to lower insulin level in the body due to autoimmune destruction of -cells. Alterations in male reproductive system have been widely reported in diabetic human and also in model animals with diabetes.This book focuses on the alloxan induced diabetes on male reproductive hormones and testicular histology in male rabbits. This book demonstrates the effects of diabetes on animal reproductive system and will add new research and knowledge to the hazardous effects of diabetes that it contributes to the male rabbits. ····· 1036198715

Dissolved cadmium salts released in drainage water from mines may represent a significant threat to aquatic wildlife. Reproductively active aquatic animals exposed to pollutant stress undergo alterations in their biochemical and physiological functions leading to the disturbed reproductive processes. Biochemical constituents and enzymes are the first detectable / quantifiable responses to environmental changes and can serve as markers for both exposures and effects in organisms. In the edible crab Scylla serrata, the protein, carbohydrate, lipid, marker enzymes and antioxidants have been estimated in the ovary, hepatopancreas, muscle and haemolymph during various stages of the ovarian maturation. The results revealed there were declined levels of protein, carbohydrates, lipid and antioxidants in the cadmium reared crabs when compared to the control. The marker enzymes were increased in the haemolymph. The results were tested statistically and concluded that Cadmium toxicity has significant role in re-productivity. ····· 1036198655

A considerable amount of nicotine is found to be present in blood of tobacoo smokers and snuffers and is largely responsible for various physiological changes. Smokers are at a greater risk of various vascular diseases due to change in their hematological variables. It has been shown that administration of nicotine to healthy mice results in increase in white blood cell (WBC) and platelets (PLT) counts. High count of PLT may lead to thrombosis and other cardiovascular diseases. The levels of red blood cell (RBC) and haemoglobin (Hb) decreases with the dose of nicotine in mice. The levels of reproductive hormones (Lutenizing hormone & Testosterone) also decreases with the administartion of nicotine. So, high levels of nicotine in blood may affect fertility in men. ····· 1036198621

Major causes of mortality of neonatal calves were the conditions like diarrhea and pneumonia (Khan et al., 2009, Shimizu and Nagatoma 1978). The neonatal calf mortality in the first month of age is more than 80% of the total mortality in calves (Jenny et al., 1981). Mortality in calves was found due to the conditions e.g. Feeding practices, managemental practices, weather conditions, bacterial and viral infections especially those causing septicemia, diarrhea and enteritis (Blood et al., 1994).The etiology of neonatal calf diarrhea involves a variety of infectious, nutritional, immunological and environmental factors. Many of the infectious agents have been isolated and identified from the feces and tissues of diarrheic calves but the relative importance of each one has not been established.

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Pearls have been known to mankind since the beginning of civilization. The success of the pearl culture industry depends on the high rate of production of quality pearls. The value of a pearl depends on its quality, size, shape, colour and lustre. Being a product of biological origin, individual variations are bound to occur in each pearl. The secretion of the mantle or the pearl-sac, which leads to the formation of the pearl, may be organic or inorganic or both in origin, with unpredictable and subtle variations in structure and composition. The final product may range from the finest to the trash. Even under the highest possible human control, the quality of cultured pearls cannot control absolutely but can considerably improve through appropriate care in surgery and during farming. Only the size and shape of the cultured pearls are under the control of the pearl culturist. However, the colour and luster, which depend on the secretion of the pearlsac, can also improve to some extent by proper understanding of individual biological and physiological factors as well as the environmental conditions of the culture farms, which influence the formation of pearls. ····· 1036191515

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Indiscriminate use of pesticides contributes to elimination of parasitoid guild and development of pesticide resistance. As part of classical biological control, two parasitoids Diadegma semiclausum and Cotesia plutellae were imported from Taiwan and South Africa, respectively and released in the highlands and semi arid areas of Kenya. Two years after the release, research was conducted to investigate the role of wild crucifers on diamondback moth and its parasitoids. The wild crucifers were found to act as refugia for both indigenous and exotic parasitoids and were suitable for parasitoid development. Parasitoids migrated from the wild crucifers to cultivated fields. It therefore would be beneficial to leave weeds as a resource for the natural enemies that inhabit the ecosystems as they act as alternative hosts and provide refugia to parasitoids that risk extinction from pesticide application. The information in this book is intended for use by Masters and PhD students, researchers in IPM especially biological control, ecologists, and biodiversity conservationists. ····· 1036191406
