摘要

尽管体型庞大，但受保护的掠食性丛林蟋蟀Saga pedo（Pallas，1771）很难在野外进行研究。这主要是由于它的模仿性强，夜间活动普遍，人口密度低。本研究的目的是通过使用发光标签并记录它们在夜间的出现来调查一些成年个体的空间行为。受监测的个体在产卵期移动很大，在研究区域的小区域发现的频率更高。为了解释这种行为，实现了两个计数数据模型。结果表明，它们的空间行为主要与猎物在可用环境中的可用性有关。此外，对HymenopteraSphex随葬品Gussakovskij（1934）的掠夺也是首次报道。

A field study on Saga pedo (Ensifera, Tettigoniidae, Saginae): Spatial behavior of adult specimens

Despite its large size, the protected predatory bush-cricket Saga pedo (Pallas, 1771) is difficult to study in the field. This is mainly due to its strong mimicry, prevalent night activity, and low population density. The aim of this study was to investigate the spatial behavior of some adult individuals through the use of luminescent tags and recording their occurrences at night. The monitored individuals moved considerably during the oviposition period and were found more frequently in small sections of the study area. Two models for count data were implemented to try to explain this behavior. The results indicate that their spatial behavior was predominantly related to the prey availability in the available environment. In addition, predation on the HymenopteraSphex funerarius Gussakovskij, 1934 is reported for the first time.
