摘要: 在黑胸散白蚁Reticulitermes chinensis发育和分化过程中,发现有假工蚁、假若蚁两种虫态。假工蚁由6龄和7龄工蚁转化发育而来,假若蚁由4龄和5龄若蚁转化发育而来。显微测量结果表明,黑胸散白蚁的胚后发育主要包括2个龄期的幼蚁期、6个以上龄期的工蚁期、4个龄期的若蚁期和有翅成虫。在此基础上分析了其他虫态的分化来源,发现兵蚁由3~7龄工蚁分化发育而来,翅鳞型和长翅芽型补充生殖蚁由6龄若蚁转化发育而来,短翅芽型补充生殖蚁由4龄和5龄若蚁转化发育而来,微翅芽型补充生殖蚁既可由4~6龄工蚁转化发育而来,又可由假工蚁和假若蚁转化发育而来,无翅型补充生殖蚁由3~7龄工蚁转化发育而来。提出了黑胸散白蚁群体中不同品级个体的可能分化途径。

Abstract: The pseudo-worker and pseudo-nymph were recognized during the development and differentiation of the immature stage of Reticulitermes chinensis.The workers of 6th and 7th instars turned into the pseudo-workers,while the nymphs of the 4th and 5th instars turned into the pseudo-nymphs.Microscopic measurement showed that after hatching the main development stages consisted of a larval stage of two instars, a worker stage of more than six instars, a nymphal stage of four instars and an imago stage.The workers of 3rd-7th instars turned into the soldiers,the nymphs of the 6th instar turned into the scale and long-wingbud replacement reproductives, the nymphs of the 4th and 5th instars turned into the shortwingbud replacement reproductives,the workers of 4th-6th instars, pseudoworker and pseudo-nymph turned into the miniwingbud replacement reproductives and the workers of the 3rd-7th instars turned into the no-wingbud replacement reproductives. Based on these observations, a differentiation scheme of the various castes in Reticulitermes chinensis is proposed.
