[Effects of different combinations of temperature and humidity on fecundity and longevity of the adult Asian corn borer]
Acta Entomologica Sinica 41 (1), 70-76
Abstract: The fecundity and longevity of the adult Asian corn borer, Ostrinia furnacalis, were studied at different combinations of constant and variable temperature and relative humidity (RH) ranging from 16°C to 32°C and 20% to 100% RH, respectively. Results indicated that constant temperature of 24°C and RH 90% to 100% were optimum for egg production, fertilization and adult mating. When the temperature was lower or higher than 24°C and humidity was lower than RH 70%, they would significantly reduce the number of eggs laid per female, egg fertilization and mating frequency. The life spans of the male and female moths were longer at lower temperature than at higher temperature, and shorter at lower relative humidity than at higher relative humidity but male moths could survive longer than females at the lower temperatures. Compared with the constant temperature, the variable temperature (28°C ~ 20°C) tested was more favorable for egg production than 16°C, 20°C, 28°C and 32°C , but as favorable as the constant temperature of 24°C. Results obtained are of very importance for population dynamics studies of the pest.
