The longevity of forestry insects used in fumigation trials was investigated in the laboratory Different life stages must sometimes be maintained for several weeks before trials can start If insects can be stored with confidence then field collection can be made whenever seasonal and or daily weather conditions are suitable Burnt pine longhorn adults collected from log export ports were kept at 8 12 16 and 20C Surviving adults were counted every other day Those held at 8C survived on average 214 days compared with 43 days at 20C Fresh burnt pine longhorn eggs were stored at 1 5 8 and 12C for 5 weeks Those stored at 12C produced over 60 larval emergence whereas those at 1 and 5C had only 36 emergence after 3 weeks Burnt pine longhorn were reared from eggs at 12 15 18 and 20C using an artificial diet Burnt pine longhorn larvae increased in mean weight from 42 mg to 5117 mg over 120 days at 20C Below 18C no larvae survived beyond 56 days Small goldenhaired bark beetle larvae were reared on the same diet at 12 16 and 20C A few larvae grew into adults at 20C
