项目摘要

This project aims to clarify long term dynamics of insect populations in Java and Sumatra, Indonesia. We established three major study sites under different climate conditions, (1) Padang, central Sumatra, has a typical humid tropical climate without a distinct alternation of wet and dry seasons. Annual rainfall exceeds 5000mm, (2) Bogor, west Java, located at the eastern fringe of the humid tropical climate, has an annual rainfall of 4075mm with more seasonality than Padang, (3) Purwodadi, east Java, has a distinctly seasonal climate. Annual rainfall is > 2000mm with 2-6 consecutive months of < 100mm rainfall. Major study species included phytophagous lady beetles (Coleoptera : Coccinellidae : Epilachninae), tortoise beetles (Coleoptera : Chrysomelidae : Cassidinae), and the banana skipper Erionota thrax (Lepidoptera : Hesperiidae). Seasonal fluctuation in abundance and mortality factors of these insect populations has been documented in detail in relation to the changes in climatic conditions and the action of natural enemies. Regular field census, including mark-recapture of adults and construction of life tables, was carried on the lady beetles (Epilachna emarginata in Bogor, E.vigintioctopunctata in Bogor, Padang and Purwodadi), and on the tortoise beetles (Aspidomorpha miliaris and A.sanctaecrucis in both Bogor and Purwodadi). The census periods for these studies have covered from 2 to 4 years, and some of them are still going on. Eggs, larvae, and pupae of the banana skipper were collected at a regular interval from the field and reared in the laboratory to examine faunal diversity and intensity of actions of parasitic wasps and flies. Laboratory rearings were also executed to clarify the survivorship and reproductive schedules of E.vigintioctopunctata collected from Bogor, Wonogiri (central Java), Sukarami (central Sumatra).

该项目旨在阐明印度尼西亚爪哇和苏门答腊的昆虫种群的长期动态。我们在不同气候条件下建立了三个主要的研究地点：（1）苏门答腊中部的巴塘，具有典型的湿润热带气候，没有明显的干湿季节交替。年降雨量超过5000 mm，（2）西爪哇的博戈尔，位于湿润热带气候的东部边缘，年降雨量为4075 mm，季节性比巴塘强，（3）东爪哇的普沃达迪，季节性气候明显。年降雨量> 2000 mm，连续2-6个月降雨量<100 mm。主要的研究物种包括植食性瓢虫（鞘翅目：瓢虫科：Epilachninae），龟甲虫（鞘翅目：龟甲科：Cassidinae），和香蕉船长Erionota thrax（鳞翅目：弄蝶科）。这些昆虫种群的丰度和死亡率因子的季节波动与气候条件的变化和天敌的作用有关。对瓢虫（博戈尔的斑翅瓢虫、博戈尔、巴塘和普尔沃达迪的八星斑翅瓢虫）和龟鳖（博戈尔和普尔沃达迪的栗翅龟鳖和圣十字龟鳖）进行了定期的野外调查，包括成虫的标记-再捕获和生命表的编制。这些研究的普查周期从2到4年，其中一些仍在进行中。定期收集的卵，幼虫，和蛹的香蕉skipper从外地和饲养在实验室中，调查区系多样性和强度的寄生蜂和苍蝇。实验室饲养也进行了澄清的生存和繁殖时间表E.vigintioctopunctata收集自博戈尔，Wonogiri（中爪哇），Sukarami（苏门答腊中部）。
