Abstract: The experimental results showed that the hunger tolerance (HT) of different wing forms Microvelia horvathi adults had significant difference at 14～32℃,and decreased with increasing temperature,which was 32.10 and 29.58 days at 14℃, and 9.46 and 7.82 days at 32℃, respectively for apterous and pterygote adults.The HT of apterous adults was higher than that of pterygote ones,and females was higher than males with the same wing form.The lower the temperature,the bigger the difference.The HT of M.horvathi adults differed obviously with densities.1 female 1 male per bottle had a higher HT than 5 females 5 males per bottle and 10 females 10 males per bottle,while no difference was found between two latter densities.The HT of the lst instar nymphs of M.horvathi had an obvious difference at different temperatures,which was significantly higher at 14 and 20℃ than at 26 and 32℃.
