Antixenosis resistance to leaf miner Leucoptera coffeella in Coffea species

Euphytica, 2011
The 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.

The effects of thiamethoxam on coffee seedling morphophysiology and Neotropical leaf miner (Leucoptera coffeella) infestations

Pest Management Science, 2022
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 ...

The Leucoptera Leaf Miners of Coffee on Kilimanjaro. I.—Leucoptera coffeella, Guér

Bulletin of Entomological Research, 1948
Two 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)

Ecotoxicology
Agricultural 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.

EFEITOS DE INSETICÍDAS E FUNGICÍDAS SOB A OVIPOSIÇÃO DO BICHO-MINEIRO (LEUCOPTERA COFFEELLA)

2022
A 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 ...
