Abstract: The present paper deals with the influence of humidity on the citrus leaf miner, Phyllocoistis citrella Stn. The results of investigation showed that: 1)Under the condition of 7 relative humidities(35%,45%,55%,65%,75%,85%,95%),the effect of humidity on the leaf miner survival (S(RH)) can be described with the model proposed by Wang Rusong et al.(1980); 2)the most sui ̄table humidity of the citrus leaf miner is 80%, the minimum critical humidity is 35%, the maximum critical humidity is 95%-96%; 3)as to the resistance to drought, eggs are the strongest, larvae the second, pupae the third, the old larvae have a stronger resistance to drought than the young; 4) between the minimum critical humidity and the suitable humidity, the survival curve can be fitted with the type of Devey Ⅲ.

Key words: percentage of precipitation anomaly, seasonal drought, southern China.
