摘要:

目的: 研究和明确黑胸散白蚁肛交哺物质的来源,为进一步研究交哺机理和白蚁防治提供参考。方法: 利用显微解剖比较不同类型个体消化道形态变化,测定不同龄工蚁后肠囊形胃(P3)以及结肠(P4)+直肠(P5)的蛋白质含量,确定黑胸散白蚁肛交哺物质的来源。通过统计不同巢群中不同龄工蚁的比例,分析不同龄工蚁在肛交哺过程中的"供体"、"受体"关系。结果: 1) 蚁后P3明显膨大,内容物黏稠状、黄褐色;工蚁P3较膨大,内容物黏稠状、黄褐色;兵蚁P3较膨大,内容物浓液体状、白色;3龄幼蚁P3具雏形,内容物液体状、白色;有翅成虫P3内容物黏稠状、淡黄色。2)工蚁、兵蚁、有翅成虫、蚁后后肠的P1、P4、P5部分大小相近,与交哺物质来源关系不大。工蚁、兵蚁、蚁后后肠P3部分大小差异未达到显著水平,但内容物颜色明显不同,P3内容物颜色可以作为判断肛交哺"供体"或"受体"的直观指标。3)2~6龄工蚁P3蛋白质含量均高于P4+P5,说明后肠不同部位蛋白质含量也可作为判断肛交哺物质来源的指标。4)2~3龄工蚁占工蚁总数的50%以上,随着蚁群的发育,4龄工蚁比例略有上升。结论: P3是肛交哺物质来源的主要场所,2、3龄工蚁是巢群中肛交哺活动的主要"供体"。

Abstract:

Objective: This study aims to investigate the sources of the proctodeal trophallaxis substances of Reticulitermes chinensis,and provide reference for further study on the mechanism of trophallaxis and control of the termite. Method: The morphological changes of the alimentary canal in different types of individuals were compared by microanatomy. The contents of protein in the paunch (P3) and colon (P4) + rectum (P5) in different instar workers were measured,and the sources of the proctodeal trophallaxis substances of R. chinensis were determined. The relationship between "provider" and "recipient" of different instar workers in the proctodeal trophallaxis was inferred by counting the proportion of different instar workers in different nests. Result: 1) The P3 of the queen was the most developed among different types of individuals and its contents were viscous and yellowish brown color. The P3 of the worker was relatively developed and its contents were viscous and yellowish brown color. The P3 of soldier was also relatively developed and its contents were thick and white color. The P3 of 3rd instar larva was still at the early stage and its contents were thick and white color. The contents of P3 were sticky and light yellow color in alate. 2) The P1,P4 and P5 of workers,soldiers,alates and queens were all similar in size with each other,suggesting that there is little relationship between the sources of the trophallaxis substances and the sizes of P1,P4 and P5. There was no significant difference in the size of the P3 among workers,soldiers and queens,but the color of the contents was obviously different. Thus,the color of the contents in P3 could be used as a morphological index to judge the "provider" or "recipient" of proctodeal trophallaxis. 3) In 2nd-6th instar workers,the protein content of P3 was higher than that of P4+P5,respectively. It was suggested that protein content in different parts of hindgut could also be used as a judging index of the trophallaxis substances origination. (4) The 2nd-3rd instar workers accounted for more than 50% of the total number of workers. With the development of colony,the proportion of the 4rd instar worker increased slightly. Conclusion: P3 is the main source site of the proctodeal trophallaxis substance. The 2nd and the 3rd instar workers are the main "provider" of proctodeal trophallaxis substances.
