Studies on the shootborer Hypsipyla grandella (Zeller) (Lepidoptera, Pyralidae). XXI. A new method to obtain oviposition in captivity


, : Studies on the shootborer Hypsipyla grandella (Zeller) (Lepidoptera, Pyralidae). XXI. A new method to obtain oviposition in captivity. Turrialba 23(3): 367-370

In this further part of a series from Costa Rica (cf. preceding abstract, etc.), the authors report that, during the rearing of Hypsipyla grandella (Zell.), they found that the average number of fertilised eggs/female could be increased from the 109.8 obtained when mated females were kept in screened outdoor cages to 210.7 when the mated females were placed individually in small plastic boxes (12 X 9 X 3.5 cm) lined with a paper towel and kept in the laboratory.
