Antixenosis resistance to leaf miner Leucoptera coffeella in Coffea species
Euphytica, 2011The coffee leaf miner, Leucoptera coffeella, is the most important pest of Coffea arabica plantations in Brazil, and all cultivars are susceptible to the insect. However, distinct reactions have been observed in other species, such as C. congensis and C. canephora.

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 ...

EFEITOS DE INSETICÍDAS E FUNGICÍDAS SOB A OVIPOSIÇÃO DO BICHO-MINEIRO (LEUCOPTERA COFFEELLA)
2022A alta taxa de oviposição é um fator importante para o sucesso dos insetos no ambiente. O bicho mineiro-do-cafeeiro, Leucoptera coffeella (Guérin-Méneville & Perrottet, 1842) (Lepidoptera: Lyonetiidae) é considerada a principal praga do cafeeiro. Para um posicionamento adequado e um controle eficiente, é necessário conhecer a biologia do inseto e ...

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.

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.

Comportamento de acasalamento do bicho-mineiro-do-cafeeiro, Leucoptera coffeella (Guérin-Mèneville) (Lepidoptera: Lyonetiidae) [PDF]
Neotropical Entomology, 2007 Leucoptera coffeella (Guérin-Mèneville) é praga-chave na cafeicultura; contudo, faltam informações sobre sua reprodução para o desenvolvimento de táticas de controle por comportamento. Este trabalho teve como objetivos determinar a periodicidade de cópulas; a periodicidade de captura dos machos e caracterizar o comportamento de acasalamento de L ...

AbstractBACKGROUNDCoffee (Coffea arabica L.) is one of the main commodities produced in Brazil. Insecticides like the (systemic) neonicotinoid thiamethoxam are widely used to suppress pest populations during coffee production, in particular the Neotropical leaf miner (Leucoptera coffeella Guérin‐Mèneville & Perrottet, 1842) (Lepidoptera ...
