     The study, published this month in the journal Oecologia, reveals a new wrinkle in how insecticides may be impactingecosystems. Mosquitoes in the study area in Costa Rica have evolved resistance to common chemicals meant to kill them andother pests. The mosquitoes’ predators, meanwhile, have not kept pace with that evolution—and that has allowed themosquito population to boom. Edd Hammill, an ecologist at Utah State University and leading author of the study, first gotan inkling that insecticides might not be having their intended effect while conducting research in orange plantations innorthern Costa Rica.
      “We felt like we were getting a lot more mosquito bites in plantations than in pristine areas and started to wonder why,”Hammill says. So he and his team surveyed where the mosquitoes were coming from: bromeliads, a group of plants found inwarm parts of the Americas, often growing on tree branches. The water-filled spaces between their tightly overlapping leaves______ a whole community of insect larvae, including mosquitoes of the species Wyeomyia abebala.
