通过对两个成熟的多角形巢的温度测定，研究了巢的热环境。在有成蜂的情况下（试验1）和除去成蜂后（试验2）测量了aPolybia paulistanest的温度，并在aP中测量了温度。当被成年黄蜂居住时，测量了Occupentalisnest（试验3）。在每次试验中，C-C热电偶被设置在巢内的四个点和巢外的两个点，以发现环境和底层温度。在试验1中，巢温基本上跟随环境温度，但在白天，巢温低于环境温度，这种关系在夜间被逆转。内基层点的温度波动小于外基层点。试验2的趋势与试验1的趋势非常相似，表明成虫的存在实际上缺乏热效应。在试验3中，P.结果表明，在2000年，Occurmentalisnest表现出与P.但当清晨阳光直射时，巢内温度迅速上升。从这些结果，在thebolyanests的热特性进行了讨论，关系到巢建筑和它们的地理分布。
Temperatures in two maturePolybianests were measured to study the thermal conditions of nests. Temperatures in aPolybia paulistanest were measured when it had adult wasps (trial 1) and after the adult wasps were removed (trial 2), and temperatures in aP. occidentalisnest were measured when inhabited by adult wasps (trial 3). In each trial, C–C thermocouples were set at four points in the nest and at two points outside to discover the ambient and substratum temperatures. In trial 1, nest temperatures basically followed the ambient temperature, but during the day the nest temperatures were lower than the ambient temperature and this relationship was reversed during the night. The temperature fluctuation of the inner substratum points was smaller than that of the outer points. The trend of trial 2 was closely similar to that of trial 1, showing a virtual lack of thermal effects from the presence of adult wasps. In trial 3, the changing pattern in theP. occidentalisnest showed a trend similar to that in theP. paulistanest, but the inside temperatures rose quickly when the nest received direct sunlight in the morning. From these results, thermal characteristics in thePolybianests are discussed in relation to the nest architecture and their geographical distribution.
