Abstract: The effects of different nutritive materials on the longevity and fecundity of Elasmus punctulatus raised in single-tube feeding method were studied. The results showed that there have the significant difference between the longevity of male and female E. punctulatus, the longevity of wasps fed with sugars was 3-9 fold longer than those fed with pollen, water or no foods. More over, the longevity of the wasps fed with 15% honey could reach 35.2¡À1.1d, 14-fold longer than those with out foods. the fecundity of the wasps fed with 10% and 15% glucose could reach 67.5¡À3.4 eggs and 65.6¡À2.7 eggs, respectively, 10-fold longer than those fed with water. The results provide useful information for mass rearing of E. punctulatus.

Single-tube feeding method was used to research the effects of different nutritive materials on the longevity and fecundity of Elasmus punctulatus. The results showed that there was significant difference  between the longevity of male and female E. punctulatus fed by glucose, sugar and honey respectively(p<0.05) while there was no significant differences.
