自然界的生物群中,某些物种对于同一地区内的综合外界环境条件有相同的时间性反应,我们利用这个原理,对日本松干蚧的发生与物候现象的关系进行了系统观察,现将结果整理如下(见附表)。 从表中可以看出,日本松干蚧各虫态的出现与本地区的树种,农作物的某一生长时期有 Some species in nature have the same temporal response to the comprehensive external environmental conditions in the same area. By using this principle, we systematically observed the relationship between the occurrence of Matochromis soborrii and phenological phenomena in Japan. The results are summarized as follows (See Schedule). As can be seen from the table, the emergence of the Japanese Songjian scale insect species and the region’s tree species, crop growth period of a
