The relationship between the survival of different ages of Tetrastichu

s hagenowii (Ratzeburg) in different stages and the period of cold storage at

10℃ were studied. The

 results showed that when the eggs were stored 10 d and 20 drespectively, their

developmental period of stored individuals were 66 and 94 d longer than th

e co

ntrol, respectively, and the number of their offspring  emerged from per ootheca

 was 10 individuals and 98 individuals, respectively, less than the control. W

h

en the eggs of T. hagenowii were stored 30 to 90 d, the eggs did not survi

ve. Wh

en the larvae of T. hagenowii were stored 10 to 90 d, their development we

re 1

8 to 263 d longer than that without cold treatment, and the number of offs

pring

 emerged per ootheca was 56 individuals to 503 individuals less than the con

tr

ol. Their emergence rate of ootheca was 84％ to 704％ less than the control.

 W

hen the pupae of T. hagenowii were stored from 10 to 90 d, their developme

ntal p

eriod was 34 to 175 d shorter than the control. The longer period of cold

stor

age, the less individual number of offspring  emerged per ootheca, and the lower

 emergence rate of ootheca.
