Life histroy strategy of tropical insects

目的：为了研究昆虫生活史策略的进化，我们在爪哇和苏门答腊岛建立了不同降雨和海拔条件下的永久研究点。(1)田间昆虫种群规模和生理状况的季节消长，以及室内条件下昆虫滞育、光周期、耐温等性状的变化。研究的昆虫包括食植物瓢虫、龟甲虫、果蝇、蚂蚁和蟋蟀。主要研究结果如下：(1)在苏门答腊和爪哇岛共发现26种食植物瓢虫，并记录寄主植物和生活史资料。(2) 21种印度尼西亚和植食性瓢虫的产卵模式，(3)热带（印度尼西亚）、亚热带（冲绳）和温带（广岛）三种瓢虫的滞育和对极端温度的耐寒性，(4)大腹蛇的生存和繁殖期，(5)西爪哇茂物植物园蚂蚁物种多样性，(6)爪哇和苏门答腊2 ~ 4个永久研究点3种毛甲和2种龟甲蛛形甲连续9年（最长）的种群动态；(7)茂物植物园分离虫Melamphaus faber及其掠食性虫Raxa nishidai 9年种群动态；(8)苏门答腊高原陆生节肢动物丰度波动。

Purpose : In order to study evolution of life history strategies of insects, we established several permanent study sites in Java and Sumatra under different rainfall and elevational conditions. We studied (1) Seasonal fluctuation of population size and physiological conditions of insects in the fields, and traits such as diapause, photoperiodism and temperate tolerance, etc. under laboratory conditions. Study insects include phytophagous ladybird beetles Epilachna, tortoise beetles Aspidomorpha, Drosophila flies, ants and, crickets. Maior results obtained are as follows, (1) Enumeration of 26 phytophagous ladybird beetles species with records of host plants and life history data from Sumatra and Java. (2) Oviposition patterns of 21 species of Indonesian and phytophagous ladybird beetle, (3) Diapause and tolerance to extreme temperatures in tropical (Indonesia), subtropical (Okinawa) and temperate (Hiroshima) populations of Epilachna vigintioctopunctata, (4) Survivorship and fertility schedules of E. pytho, (5) Ant species diversity in the Bogor Botanic Garden, West Java, (6) Long-term population dynamics of 3 Epilachna species and 2 species of tortoise beetles Aspidomorpha for (at longest) 9 successive years on 2-4 permanent study sites in Java and Sumatra, (7) Population dynamics of an isolated pyrrhocorid bug Melamphaus faberand its predatory bug Raxa nishidai in the Bogor Botanic Gardens for 9 years, (8) Fluctuation in the abundance of terrestrial arthropods at an Sumatran Highland.
