Book Description
There are over a million different species of insects, and individually they 8 outnumber humans by more than 10 to 1. Moreover, some insects live in close association with both plants and higher animals and naturally exchange viruses with them. It has even been speculated that viruses in general may have radiated through the plant and animal kingdoms from common insect origins. Be that as it may, since insects play pivotal roles in the biosphere, both to the benefit and detriment of mankind, they and the viruses that infect them are important subjects for study. Insects are infected by a diverse medley of viruses, and this volume focuses on those insect virus families that are found primarily or exclusively in insects. All major families of insect-selective viruses are covered except for the baculo viruses, which were described in a separate volume of The Viruses series. Included in this volume are the established families of insect viruses, the newly recognized ascovirus family, and the nudiviruses, which probably represent a separate family but currently remain unclassified. The coverage of arboviruses is limited to a single chapter that focuses on their potential utility as vectors and in insect control. Omitted for practical reasons are several individual insect viruses that have been described sporadically in the literature and probably represent novel virus families.

Book Description
Excerpt from Artificial Diets for Mass Rearing the Corn Earworm (Heliothis Zea) Each cup was charged with 10 milliliters of diet from a prepared batch of milliliters. The cups were placed in groups of 25 in a cel-pack tray, infested with 1 day-old, processed H. Zea eggs,5 and capped. Four groups of 25 cups were placed in a bundle (four replications) and held in an environmental room at. 84° 'to 85° F. And 55 to 60 percent rela tive humidity for the duration of the egg, larval, and pupal stages. The biological criteria considered in evaluating the diets were days to pupation, days to emergence, percentage viable adults, fecund ity, percentage egg hatch, adult longevity, mating, and type of sperm complements. Forty cages per diet were used to evaluate adult performance, that is, four cages containing six pairs of adults from each of the 10 trials. The adults were held at 78° to 80° F. And 75 to 80 percent relative humidity and were fed. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
