二点叶螨是影响西班牙克莱门氏小柑橘果园的最具破坏性的叶螨之一，而西班牙的自然控制不足。此外，在柑橘苗圃中，嫩叶极易受到攻击，并且几乎总是不存在天敌。因此，杀螨剂常常被滥用。在商业果园和小柑橘苗圃中，替代控制措施是必要的。为了评估 N 接种释放的功效。加利福尼亚州和 P.近似减少T.针对西班牙克莱门氏小柑橘幼苗中的荨麻疹种群，进行了半田试验，并在三个季节（春、夏、秋）重复进行。评估了两种释放率（40 和 80 植物绥虫/植物）和考虑的所有三个时期的荨麻疹感染和对植物造成的损害水平。相比之下，N. californicus 在某些条件下表现出较低的性能。这项研究的结果可以进行调整并转移到苗圃和年轻的柑橘种植园。
Tetranychus urticaeis one of the most damaging tetranychid mites affecting clementine orchards in Spain, where natural control is insufficient. Furthermore, in clementine nurseries, tender foliage is highly susceptible to attack and natural enemies are almost always absent. Therefore, acaricides are often used indiscriminately. Alternative control measures are necessary, both in commercial orchards and clementine nurseries. In order to assess the efficacy of inoculative releases ofN. californicusandP. persimilisto reduceT. urticaepopulations in young Spanish clementine plants, a semi-field experiment was conducted and repeated in three seasons (spring, summer and autumn).Phytoseiulus persimiliswas highly effective in reducing bothT. urticaeinfestations and the damage level inflicted on plants at both release rates evaluated (40 and 80 phytoseiids/plant) and all three periods considered. By contrast,N. californicusdemonstrated low performance under certain conditions. The results of this study could be adapted and transferred to nurseries and young citrus plantations.
