By fitting the models of semivariogram of them and analyzing the patterns, it was found that the nugget range of macropterous SBPH and larval SBPH were approaching to that of spiders, as well as the range of structural intensity, but the nuggets of SBPH were not approaching to that of spiders, neither the structural intensity. The spatial pattern of larval SBPH and spiders were aggregation, but that of macropterous SBPH was random sometimes.

通过变差函数模型的拟合及空间格局的分析，得出灰飞虱长翅成虫、若虫与蜘蛛的变程范围相近，结构性强度的范围相近，但同一时间灰飞虱与蜘蛛的变程和结构性强度则均不尽相同；灰飞虱若虫与蜘蛛自始至终为聚集分布，但灰飞虱长翅成虫与蜘蛛的分布型则有差异，在某些时间为均匀分布。

We drawn the predicted surface maps with the Ordinary Kriging method and illustrated in the time order to provide a visible presentation of the spatio-temporal distributions. By analyzing those maps, we found that the spatial distribution of spiders in the paddy field was similar to that of macropterous SBPH and larval SBPH, and was more similar to larval SBPH, and showed an obvious pursuing phenomenon between them, while the pursuing had a close relationship with the temporal dynamics of SBPH number. But the pursuing phenomenon was complex and influenced by factors such as the weather, the environmental conditions in paddy fields, other enemies of SBPH and other foods of spiders.

用普通克立格方法作出空间分布图，在时间序列上进行比较分析，得出稻田蜘蛛与灰飞虱成若虫的空间分布均有相似性，尤其与若虫相似性更强，表现出比较明显的空间跟随现象，且空间跟随现象与灰飞虱虫量的消长有密切的关系，但是由于天气、稻田环境、灰飞虱其他天敌以及蜘蛛其他猎物的存在等因素的影响使得其空间跟随又有着相当的复杂性。

These results suggest that pyriproxyfen obviously influences the larval growth to adult worker bees, especially in the pupal growth. The lower dose of pyriproxyfen results in abnormal eclosion, and more effects respond to the increasing doses, the treated larvae gradually appear the failure to eclosion, melanic death in the pupal stage, and death in the larval stage.

上述结果显示，百利普芬对成蜂的毒性较低，却会明显影响蜜蜂幼虫的生长发育，低剂量会造成蜜蜂羽化不完全，随著剂量的增加，处理幼虫的发育有提早的现象，处理幼虫会渐次出现蛹体变黑死亡，羽化失败死亡，甚至幼虫期即死亡的现象。
