A new concept for insect damage evaluation based on plant physiological variables
The objective of this study was to determine the damage levels caused by Orthezia praelonga Douglas, 1891 and Leucoptera coffeella (Guérin-Mèneville 1842), on rangpur lime and Obatã coffee leaves, respectively.

The assembly and importance of a novel ecosystem: The ant community of coffee farms in Puerto Rico
Here, we describe the arboreally foraging ant community in 25 coffee farms in Puerto Rico. We find that the majority of the dominant species are non‐native. Through a detailed study of two of the farms, we describe the interactions between two non‐native dominant species, Wasmannia auropunctata and Solenopsis invicta.

Insecticide use and organophosphate resistance in the coffee leaf miner Leucoptera coffeella (Lepidoptera: Lyonetiidae) [PDF]
AbstractIncreasing rates of insecticide use against the coffee leaf miner Leucoptera coffeella (Guérin-Méneville) and field reports on insecticide resistance led to an investigation of the possible occurrence of resistance of this species to some of the oldest insecticides used against it in Brazil: chlorpyrifos, disulfoton, ethion and methyl parathion.

Coffee leaf volatiles and egg laying by the coffee leaf miner Leucoptera coffeella
Abstract Recent reports of coffee genotypes resistant to one of its key pests in the Neotropical region, the leaf miner Leucoptera coffeella (Lepidoptera: Lyonetiidae), sparked studies trying to recognize the underlying causes of resistance. An association between increased egg laying by the leaf miner and increased caffeine levels in coffee leaves ...
