Abstract

内容記述

Population cycles have fascinated ecologists since the early 19th century, and dynamics of insect populations have been central to understanding the intrinsic and extrinsic biological processes responsible for these cycles. We analyzed an extraordinary long-term dataset (every 5 days for 48 years) of a tea tortrix moth (Adoxophyes honmai) which exhibits two dominant cycles: a conspicuous 4-5 single-generation cycles in a year superimposed on an annual cycle. General theory offers several candidate mechanisms for generation cycles. To evaluate these we construct and parameterize a series of temperature dependent stage-structured models that includes intraspecific competition, parasitism, mate-finding Allee effects and adult senescence, all in the context of a seasonal environment. By comparing the observed dynamics with predictions from the models, we find that even weak larval competition in the presence of seasonal temperature forcing predicts the two cycles accurately. None of the other mechanism predicts the dynamics. Detailed dissection of the results shows that a short reproductive life-span and differential winter mortality among stages are the additional life-cycle characteristics that permits the sustained cycles. Our general modeling approach is applicable to a wide range of organisms with temperature-dependent life-histories, and is likely to prove particularly useful in temperate systems where insect pest outbreaks are both density- and temperature-dependent.
