Present experiments were set 5 different temperature conditions as 14, 18, 22, 16, 30 ℃ to compare the variation of cannibalism behavior and related effects to development of Harmonia axyridis 4th stage larvae in Sibling and Non-sibling. The results showed significant effects of temperatures on the cannibalism ratio both in two kin groups. And under 22-24℃, the cannibalism ratio in sibling group was lower than non-sibling group significantly. We found the effect of temperatures on lag duration of cannibalism was also significant and the lag duration in non-sibling group was higher than the other. The mutual attack ratio wasn’t influenced by temperature variation significantly. The exception of the mutual attack ratio was showed significantly different between two kin groups when the temperatures were high than 22 ℃. Furthermore, the significant differences of total suffering cannibalism attack times were shown among different temperatures. For the observation of cannibalism mortality, a reduced tendency with temperature increasing was shown in sibling group and the mortalities were all higher than 30%. On the contrast, the mortality in non-sibling group wasn't influenced by temperature variation, and all mortalities were higher than 70%. The pupae ratio and emergency ratio of survivors were not influenced by temperature and kin-relationship variation significantly. The pupae ratio in each temperature was high than 90% consistently except in 30 ℃. And the emergency ratios in all temperatures were higher than 70%.
