红火蚁的巢间相容性

在室内条件下通过将红火蚁Solenopsis invicta Buren异巢不同品级的个体置于同一容器中,对红火蚁的巢间相容性进行研究。结果表明,蚁后与异巢幼蚁共处时,异巢幼蚁的羽化率为33.3%,与对照处理的38.3%(蚁后与同巢幼蚁共处)无显著差异。工蚁与异巢幼蚁共处时,异巢幼蚁的羽化率为53.7%,与对照处理的72.2%(工蚁与同巢幼蚁共处)无显著差异。蚁后与异巢工蚁共处时,异巢蚁后的存活率为45%,与对照处理的61.7%(工蚁与同巢蚁后共处)无显著差异。有翅繁殖雌蚁与异巢工蚁共处时,异巢工蚁的存活率为86.7%与对照处理的99.4%(工蚁与同巢有翅繁殖雌蚁共处)存在显著差异;异巢有翅雌蚁的存活率为22.2%,与对照处理的88.9%(工蚁与同巢有翅繁殖雌蚁共处)存在显著差异。由此可见,同区域内红火蚁异巢各品级间存在一定程度的相容性,并巢行为有可能发生。

The compatibility between different nests of Solenopsis invicta

The compatibility between different nests of Solenopsis invicta Buren was studied by putting individuals of different castes in one container.The results showed that when queens and larae from different nests were together,the eclosion rate of larvae(33.3%) was not significantly different with that(38.3%) when queens and larvae were from same nest.When workers and larvae from different nests were together,the eclosion rate of larvae(53.7%) was not significantly different with that(72.2%) when orkers and larvae were from same nest.When queens and workers from different nests were together,the survival rate of queens(45%) was not significantly different with that(61.7%) when queens and workers were from same nest.When female alates and workers from different nests were together,the survival rate of workers(86.7%) and female alates(22.2%) was significantly lower than those(99.4% and 88.9%) when female alates and workers were from same nest.Therefore,there was a little compatibility between castes from different nests,and colong fusion could happen in S.invicta.
