We examined the role of phenolic compounds, and the enzymes peroxidase and polyphenol oxidase, in the expression of resistance of coffee plants to Leucoptera coffeella (Lepidoptera: Lyonetiidae). The concentrations of total soluble phenols and chlorogenic acid (5-caffeoylquinic acid), and the activities of the oxidative enzymes peroxidase (POD) and ...

Hidden target, hidden effects: chlorantraniliprole on the coffee leaf miner (Leucoptera coffeella)
EcotoxicologyAgricultural insecticide usage presents a complex challenge, particularly when addressing hidden targets such as concealed pest species. Typically, insecticide spraying targets either the host plant or the soil substrate, reaching the target when the pests move or feed, yet their vulnerability when concealed remains low.

The Leucoptera Leaf Miners of Coffee on Kilimanjaro. I.—Leucoptera coffeella, Guér
Bulletin of Entomological Research, 1948Two leaf miners of coffee, Leucoptera coffeella and L. caffeina are present in the Kilimanjaro and Usambara districts of Tanganyika. The life-histories of L. coffeella and its parasites and a study made during 1937–40 of the populations of the host and its parasites in the Kilimanjaro area in both unshaded and shaded coffee are described.

The Parasites of the Coffee Leaf-Miners (Leucopteraspp.) in Africa
Bulletin of Entomological Research, 1936The coffee leaf-miners of the genusLeucoptera, Hübner, are serious pests of coffee wherever it is cultivated and they have often caused great anxiety to planters in many parts of the world.Leucoptera coffeella, Guér., is known from the West Indies, Central and South America, Central Africa, Madagascar, Réunion and Ceylon. Another species,L.
