Transmission and operation mechanisms of nutrients, caste reguatory substances and symbionts in incipient colony of pedestlian social insects

进行了以下研究。(1) 5月中旬赴冲绳县利远岛采集高agoensis Nasutitermes， 5月下旬赴鹿儿岛县屋久岛采集Hodotermopsis japonica。我们还去了川西，兵库县收集了内腺虫病。(2)研究了种姓调节物质（费洛蒙）在白蚁体内的传递和士兵基因的表达。采用差分显示法测定士兵特异性基因的表达。(3)研究了日本血吸虫个体间的营养关系和幼虫的生长情况。分析了成虫至幼虫的肠道含量、脂肪体中尿酸的积累情况以及营养化发生频率。(4)研究了高asagonasutitermes早期群体的等级分化模式。(5)从营养生态学的角度对真菌生长白蚁（Odontotermes formosanus）和白蚁的象征系统进行了研究。(6)研究了食木蜚蠊（Salganea spp.）成虫对若虫的营养物质反刍传播。(7)研究了大翅蚁（Pheidde megacephaus）早期群体的种姓分化。(8)我们就上述研究发表了10篇论文。

The following researches were carried out.(1) We traveled for lriomote island, Okinawa pref. in middle May to collect Nasutitermes takasagoensis, for Yakushima island , Kagoshima pref. in late May to collect Hodotermopsis japonica. And also we traveled for Kawanishi, Hyogo pref. to collect Zootermopsis nevadensis.(2) Transmission of caste regulatory substances (pheromone) and gene expression of soldier in termites : were investigated. The expression of soldier specific gene is determined by Differential display method.(3) Trophallaxis btween individuals and growth of larvae in H.japonica were investigated. Analysis of gut content, accumulation of uric acid in fat body, and frequency of trophallaxis from adults to larvae were carried out.(4) Pattern of caste diffrentiatin in incipient colony of Nasutitermes takasagoensis was investigated.(5) The symboitic system in the fungus growing termite (Odontotermes formosanus)and hasidivu Was investigated on the aspect of nutritional ecology.(6) Transmission of nutritional substances by regurgitation from adults to nymphs in the wood feeding cockroaches (Salganea spp.)was investigated.(7) Caste differentiation in incipient colony of Pheidde megacephaus was investigated.(8) We published 10 papers on above studies.
