Primary and secondary parasitoids of Hypogeococcus spp. (Hemiptera: Pseudococcidae) on Cactaceae, Amaranthaceae, and Portulacaceae were reported from field surveys conducted in Puerto Rico, USA, since 2009. Resident natural enemies of the Harrisia cactus mealybug (HCM), Hypogeococcus sp., which is devastating native cacti in Puerto Rico and threatening cacti in the adjacent Caribbean islands, were documented prior to the planned introductions of non-native biological control agents from South America against this pest. Two species of Encyrtidae (Hymenoptera: Chalcidoidea) were recorded as primary parasitoids of the HCM on Cactaceae: Leptomastidea hypogeococci Triapitsyn, which was the most common, and Anagyrus quilmes Triapitsyn, Logarzo & Aguirre. Another primary parasitoid, Acerophagus sp. near nubilipennis Dozier (Encyrtidae), was also reared from a different Hypogeococcus sp. on Amaranthaceae and Portulacaceae. Hyperparasitoids, usually via L. hypogeococci, included Prochiloneurus narendrani Noyes & Triapitsyn (Encyrtidae), Pachyneuron sp. (Hymenoptera: Pteromalidae), Chartocerus elongatus (Girault), and Chartocerus niger (Ashmead) (Hymenoptera: Signiphoridae). Cheiloneurus chrisiantorresi Triapitsyn sp. n. (Encyrtidae) is newly described and illustrated; its status as a suspect hyperparasitoid of Hypogeococcus sp. on Amaranthaceae and Portulacaceae, along with that of Cheiloneurus sp., will need to be verified. The recorded HCM predators include one species of Chamaemyiidae (Diptera), Leucopina bella (Loew), and three species of Coccinellidae (Coleoptera): Cryptolaemus montrouzieri Mulsant, Decadiomus austrinus (Gordon), and Scymnobius flavifrons (Melsheimer).

波多黎各的Harrisia Cactus Mealybug和其他Hypogeococcus物种（Hemiptera：Pseudococcidae）的天敌：主要和次要寄生虫的鉴定和分类学注释。

Hypogeococcus spp的初级和次级寄生虫。自2009年以来，通过在美国波多黎各进行的野外调查，报道了仙人掌科，A菜科和马齿ae科（半翅目：假球菌）的病原体。在计划从南美引进非本地生物防治剂来防治这种有害生物之前，已记录了邻近加勒比海岛屿的里科和濒临灭绝的仙人掌。在仙人掌科上，两种钩虫科（膜翅目：opter科）被记录为HCM的主要寄生虫：最常见的是钩端螺旋体的hypogeococci Triapitsyn和Anagyrus的mesTriapitsyn，Logarzo和Aguirre。另一个主要的寄生寄生虫，食虫菌。nubilipennis Dozier（Encyrtidae）附近的鸟也从不同的Hypogeococcus sp。在A菜科和马齿ace科上。超寄生物，通常通过低聚乳球菌，包括Prochiloneurus narendrani Noyes＆Triapitsyn（Encyrtidae），Pachyneuron sp.。（膜翅目：翼龙科），长形夜蛾（Girault）和黑纹夜蛾（Ashmead）（膜翅目：Signiphoridae）。Cheiloneurus chrisiantorresi Triapitsyn sp.。。（Encyrtidae）被重新描述和说明；其作为疑似超寄生虫的地位Hypogeococcus sp。A菜科和马齿ace科上的叶霉属，以及白螯菌属上的那些，都需要进行验证。记录的HCM捕食者包括Chamaemyiidae（Diptera），Leucopina bella（Loew）的一种和Coccinellidae（Coleoptera）的三种：Cryptolaemus montrouzieri Mulsant，Decadiomus austrinus（Gordon）和Scymnobius flavifrons（Melsheimer）。
