濒临灭绝的阿塔拉斑纹蝶，Eumaeus Atala Poey 1832（鳞翅目：Lycaenidae科）是历史上生活在佛罗里达州东南部濒临灭绝的松岩生态系统中的一种特殊物种。直到最近，这种蝴蝶才使用北美唯一的本土苏铁（扎米科：苏铁科），通常被称为“coontie”，作为其后代的寄主植物。随着许多非本地和有价值的苏铁被引入植物园和家庭花园，蝴蝶扩大了它的选择，包括这些外来物种。植物和昆虫的保护都是复杂的，因为草食会损害植物，但控制幼虫的损害可能对脆弱的蝴蝶种群有害。采用幼虫和成虫寄主植物选择试验，比较了integrfolia zia vazquezii L. （Zamiaceae: Cycadales）和非本地的zia vazquezii L.（一种受欢迎的园林苏铁，在其本土墨西哥处于极度濒危状态）的幼虫存活率、发育率和随后的成虫选择。结果表明，成虫和幼虫对原生昆虫的选择多于非原生昆虫；使用巴斯克兹兹蚊后，幼虫存活率降低，但发育时间延长，成虫寿命延长。无论选择哪一种寄主，成虫都能存活到成功交配和繁殖力。讨论了避免农药使用以控制有价苏铁幼虫食草性的害虫综合治理技术。
The imperiled Atala hairstreak butterfly, Eumaeus atala Poey 1832 (Lepidoptera: Lycaenidae) is a specialist species historically living in southeast Florida’s endangered pine rockland ecosystems. Until relatively recently, the butterfly used North America’s only native cycad Zamia integrifolia L. (Zamiaceae: Cycadales), commonly called “coontie,” as the host plant for its offspring. With the introduction of many non-native and valuable cycads into botanical and domestic gardens, the butterfly has expanded its choices to include these exotic species. Conservation of both the plant and insect is complex as herbivory can damage the plant, but control of the larval damage may be detrimental to the fragile populations of the butterfly. Larval and adult host plant choice tests were implemented to compare larval survival, development rates and subsequent adult choice between Z. integrifolia and non-native Zamia vazquezii L. (Zamiaceae: Cycadales), a popular garden cycad that is critically endangered in its native Mexico. Results indicate that both adults and larvae chose native more often than non-native; larval survival decreased, but development time increased, as did adult lifespan when utilizing Z. vazquezii. Adult survival to successful mating and fecundity occurred with either host choice. Integrated pest management techniques are discussed for avoiding pesticide use to control larval herbivory on valuable cycads.
