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.
