Egg eclosion of Cryptolestes ferrugineus (Stephens) was investigated under the combined conditions of nitrogen concentrations (78.8%, 83.0% and 88.0%), relative humidity(69. 6%RH, 75.1%RH, 83.7%RH) and temperatures(19.9, 25.0, 29.3, 34.7, 39.8℃). The results showed that the development period, the development zero, the maximum development temperature and the effective accumulated temperature were 2.2~18.9 d, 13.8~14.3℃, 40.4~43.0℃ and 61.6~115.6 day-degree, respectively. The curves between the development period, development rate and the temperatures were respective 'index' and 'S'-shaped pattern. It was concluded that the interaction of nitrogen, temperature and humidity would affect egg eclosion; 88% nitrogen had significant inhibitory effects on the eclosion; Temperature (>30.0℃) and humidity (>69.6%RH) enhanced the inhibitory effect of nitrogen on egg eclosion. © 2016, Dept. of JCCOA.
