The coffee berry borer, Hypothenemus hampei (Ferrari), has at least two generalist predators that are well-known for their biological control potential, the little fire ant, Wasmannia auropunctata and various species of lizards in the genus Anolis. While it is frequently suggested that multiple control elements make biological control more efficacious, particular situations may not reveal such an effect. We investigated the relationship between these two potential biological control elements by surveying coffee bushes on 11 sites within six farms in the central coffee-producing area of Puerto Rico. At both the site level and the level of individual coffee trees, W. auropunctata had a significant negative effect on the presence of Anolis spp., suggesting that in this particular case the benefits of multiple generalist predators may be elusive.

Anolis spp之间的对抗。和波多黎各咖啡农场的Wasmannia auropunctata：对咖啡果蛀虫的生物控制的潜在并发症

咖啡果蛀虫Hypothenemus hampei（Ferrari）至少有两个以其生物防治潜力而闻名的通体捕食者，即小火蚁Wasmannia auropunctata和Anolis属中的各种蜥蜴。尽管经常建议使用多种控制元素来提高生物控制的效率，但某些特定情况可能无法揭示这种效果。我们通过调查波多黎各中部咖啡产区六个农场内11个地点的咖啡灌木，调查了这两个潜在生物防治元素之间的关系。在站点级别和单个咖啡树级别上，W。auropunctata对Anolis spp。的存在均具有显着的负面影响，这表明在这种特殊情况下，多个通才捕食者的利益可能难以捉摸。
