Molecular characterization of a miraculin-like gene differentially expressed during coffee development and coffee leaf miner infestation

Planta, 2010
The characterization of a coffee gene encoding a protein similar to miraculin-like proteins, which are members of the plant Kunitz serine trypsin inhibitor (STI) family of proteinase inhibitors (PIs), is described. PIs are important proteins in plant defence against insects and in the regulation of proteolysis during plant development.

Genetically modified coffee trees resistant to the coffee leaf miner, Perileucoptera coffeella

Journal of Chemical Ecology, 1999
A synthetic version of the Bacillus thuringiensis cry1Ac gene was used in transformation of coffee species (Coffea canephora and Coffea arabica) to confer resistance to an important pest in South America and East Africa, the coffee leaf miner (Perileucoptera coffeella and other Leucoptera spp.).

Prediction of outbreaks of coffee leaf-miners on Kilimanjaro

Bulletin of Entomological Research, 1969
Analysis of the results obtained from suction-trap catches of the coffee leaf-miners, Leucoptera meyricki Ghesq. and L. caffeina Wshbn. on an unsprayed block of coffee at the Coffee Eesearch Station, Lyamungu, on the slopes of Kilimanjaro, are given.By thermal summation methods it was possible to delimit successive generations of moths with some degree

Development of Coffee Trees Resistant to Leaf Miner

2000
The production of coffee in Brazil reached 34 million bags in 1999 being 29,5 million from Coffea arabica cultivars. Since all such cultivars are susceptible to leaf miner (Perileucoptera coffeella), the main pest in Brazil, the yield and economic losses are considerable.

Plants for fitness enhancement of a coffee leaf miner parasitoid

2022
Conservative biological control aims to enhance the pest control through the conservation of natural enemies in the field, one of the strategies used is to introduce or manage plants that provide food for natural enemies. The effect of feeding resources on the fitness of a coffee leaf miner parasitoid Proacrias coffeae was assessed.

Arboreal Ant Abundance and Leaf Miner Damage in Coffee Agroecosystems in Mexico

Biotropica, 2008
ABSTRACTShaded coffee agroecosystems traditionally have few pest problems potentially due to higher abundance and diversity of predators of herbivores. However, with coffee intensification (e.g., shade tree removal or pruning), some pest problems increase.

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.
