Sampling plan for the coffee leaf miner Leucoptera coffeella with sex pheromone traps [PDF]

Journal of Applied Entomology, 2007
The population density of the coffee leaf miner Leucoptera coffeella (Guérin‐Méneville & Perrottet) (Lep., Lyonetiidae) can be estimated using pheromone traps in coffee fields as male capture reflects this pest damage based on previous correlational ...

Leaf alkaloids, phenolics, and coffee resistance to the leaf miner Leucoptera coffeella (Lepidoptera: Lyonetiidae) [PDF]

Journal of economic entomology, 2010
Coffee (Coffea spp.) alkaloids (caffeine and related methylxanthines) and phenolics (caffeic and chlorogenic acids) have recognized pestistatic/pesticidal activity and mediate insect—plant interactions.

Functional response of 3 green lacewing species (Neuroptera: Chrysopidae) to Leucoptera coffeella (Lepidoptera: Lyonetiidae). [PDF]

J Insect Sci, 2023
AbstractGreen lacewings (Neuroptera: Chrysopidae) are predators commonly found in coffee plantations in Brazil that can serve as important biological control agents against insect pests such as the coffee leaf miner, Leucoptera coffeella (Lepidoptera: Lyonetiidae). However, the efficacy of different lacewing species in controlling L. coffeella needs to

Mitochondrial phylogenomics of the Australian scribbly gum moth Ogmograptis (Lepidoptera: Bucculatricidae) and an examination of deep‐level relationships within Lepidoptera

Austral Entomology, Volume 62, Issue 4, Page 449-463, November 2023., 2023
Abstract Larval feeding by the moth genus Ogmograptis (Bucculatricidae: Lepidoptera) creates one of the most iconic features of the Australian bush—the ‘scribbles’ found on smooth‐barked Eucalyptus. The taxonomic history of Ogmograptis has been challenging, with members of the genus being initially described in four different genera representing three ...
