Abstract:
In order to explore the effect of constant and variable temperatures on the growth and development of ［Petrobia (Tetranychina) harti (Ewing)］,the longevity,developmental duration and reproductive capacity were studied on Oxalis corymbosa under L/D＝16/8,RH 65% constant temperature and of 24℃ variable temperature(20~27℃,acerage 24℃).The results showed that there were no difference between constant and variable temperatures of developmental duration and rates of T.harti.The net reproduction rate,fecundity and average daily fecundity under constant temperature were lower than that under variable temperature;the net reproduction rate under constant temperature was 20.0200,lower than that under variable temperature(26.3333).The other parameters were no significant difference between constant and variable temperatures.
