    Summary: "Parasitoids are parasitic insects that kill their insect hosts in immature pre-reproductive stages. Parasitoids are employed in biological control programs worldwide to kill insect pests and are environmentally safe and benign alternatives to chemical pesticides. As resistance to chemical pesticides continues to escalate in many pest populations, attention is now refocusing on biologically based strategies to control pest species in agriculture and forestry as well as insect vector populations that transmit human and animal diseases. Parasitoids are an economically critical element in this equation and in integrated pest management. Viruses have evolved intimate associations with parasitoids, and this book features a large section on symbiotic viruses that are integrated into the wasp chromosomal DNA (polydnaviruses). A separate section on parasitoid venoms, which are of interest to the pharmaceutical and medical communities as well as insect-oriented biologists, is also featured"--Back cover.

    Colonoscopy is a relatively new and important diagnostic modality for evaluation colonic disease. In order to assess its value in the community hospital, all colonoscopies done by me (250 examinations in two hospitals) were reviewed. Colonoscopy was sometimes easy and sometimes long and tedious. It was difficult to reach the cecum consistently, but success improved with experience. Many neoplasma not seen on barium enema were found, including three carcinomas. Twenty-seven polyps were removed with the aid of the colonoscopic snare. No complications occurred. Colonoscopy should probably be restricted to those physicians who have a large enough case load and who can spend enough time learning the procedure to develop expertise.
