1973 ~ 1974年在美国南部加州研究了2种不同释放速率和释放时间对草莓上二斑叶螨的影响。两种斑叶螨种群在放流样地中均显著减少。从5月8日到6月19日研究结束，释放地块中的两个斑点叶螨的平均数量与对照有显著差异，但彼此之间没有差异。平均果实产量（克/株）和果实大小的释放地块也显着不同的检查，但没有从对方。早期释放的捕食者在10/厂得到了稍好的结果比其他释放率和时间的释放调查。
The effect of 2 different release rates and timings of releases of Amblyseius califamicus (McGregor) on Tetranychus urticae Koch on strawberry was investigated in southern California in 1973-74. The two spotted spider mite populations were significantly reduced in the release plots. The mean numbers of two spotted spider mites in the release plots were significantly different from the check, but not from each other, from May 8 through the end of the study on June 19. The mean fruit yields (g/plant) and fruit size in the release plots also were significantly different from the check but not from each other. Early releases of the predator at 10/plant gave slightly better results than did the other release rates and timing of releases investigated.
