The coffee leaf miner, Leucoptera coffeella (Guérin-Méneville), is one of the main pests of coffee (Coffea spp.) in the Neotropical region. Leucoptera coffeella is considered a specialist insect because it develops exclusively within the leaves of the genus Coffea. In this laboratory study, we investigated the oviposition preference and performance of L. coffeella on the coffee leaf rust (Hemileia vastatrix Berkeley & Broome)-susceptible C. arabica cultivars “Red Catuai”, “Red Caturra”, and “Typica”, and resistant cultivars “Costa Rica 95”, “Oro Azteca”, and “IAPAR 59”. Individual (non-choice) and group (multiple-choice) leaves of these cultivars were exposed to mated individual L. coffeella females and the number of eggs laid per leaf was recorded. Oviposition preference was found to be indistinct among the coffee cultivars evaluated. However, larvae and pupal period, and adult body length were significantly affected by the coffee cultivar. These results are discussed in relation to the preference-performance hypothesis and its impact on L. coffeella’s strategy to choose the host plant.

咖啡潜叶虫Leucoptera coffeella (Guérin-Méneville) 是新热带地区咖啡 ( Coffea spp.)的主要害虫之一。Leucoptera coffeella被认为是一种特殊昆虫，因为它只在咖啡属的叶子内发育。在这项实验室研究中，我们调查了L. coffeella对咖啡叶锈病 ( Hemileiavastatrix Berkeley & Broome) 易感的C. arabica的产卵偏好和表现品种“Red Catuai”、“Red Caturra”和“Typica”，以及抗性品种“哥斯达黎加 95”、“Oro Azteca”和“IAPAR 59”。将这些栽培品种的个体（非选择）和群体（多项选择）叶子暴露于交配的个体L. coffeella雌性，并记录每片叶子产卵的数量。发现在评估的咖啡品种中产卵偏好不明显。然而，幼虫和蛹期以及成虫体长受咖啡品种的显着影响。这些结果与偏好性能假设及其对L. coffeella选择寄主植物的策略的影响有关。
