During the 1950s, as the targeted insect pest populations became increasingly resistant to treatment with many chemical insecticides, higher concentrations of the insecticides were applied to control the pests. In addition, chemical insecticides were found to lack specificity; consequently, beneficial insects were killed along with those that were considered to be pests. In fact, in some instances, the natural enemies of the insect pest species were killed off more efficiently than the target organisms, with the bizarre result that pesticide treatment led to greater numbers of the insects.

在20世紀50年代，作為目標害蟲種群成為了治療性越來越與許多化學殺蟲劑，殺蟲劑的高濃度應用來控制害蟲。此外，化學殺蟲劑被發現缺乏特異性; 因此，益蟲用那些被認為是害蟲殺死了一起。事實上，在某些情況下，昆蟲害蟲物種的天敵均高於目標生物體更有效地殺死了，一起離奇結果是除害處理導致昆蟲的數量更多。

在20世紀50年代，隨著目標害蟲種群對許多化學殺蟲劑的處理越來越具有抗藥性，因此採用了更高濃度的殺蟲劑來控制害蟲。此外，化學殺蟲劑也缺乏特異性;因此，有益的昆蟲與被認為是害蟲的昆蟲一起被殺死。事實上，在某些情況下，害蟲物種的天敵比目標生物更有效地被殺死，其奇怪的結果是，殺蟲劑處理導致昆蟲數量增加。

在20世紀50年代，隨著目標害蟲種群對多種化學殺蟲劑的抗藥性日益增强，人們開始使用更高濃度的殺蟲劑來控制害蟲。此外，化學殺蟲劑被發現缺乏特异性；囙此，有益的昆蟲和被認為是害蟲的昆蟲一起被殺死。事實上，在某些情况下，害蟲物種的天敵被殺死的效率高於目標生物，這一奇怪的結果是，殺蟲劑處理導致了更多的昆蟲。
