Polyphenoloxidase activity in coffee leaves and its role in resistance against the coffee leaf miner and coffee leaf rust

Phytochemistry, 2006
In plants, PPO has been related to defense mechanism against pathogens and insects and this role was investigated in coffee trees regarding resistance against a leaf miner and coffee leaf rust disease. PPO activity was evaluated in different genotypes and in relation to methyl-jasmonate (Meja) treatment and mechanical damage.

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 [PDF]

Euphytica, 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.).

Arboreal Ant Abundance and Leaf Miner Damage in Coffee Agroecosystems in Mexico [PDF]

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.

Phenol Contents, Oxidase Activities, and the Resistance of Coffee to the Leaf Miner Leucoptera coffeella

Journal of Chemical Ecology, 2006
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 ...

Is Ceraeochrysa cubana a coffee leaf miner predator?

Biological Control, 2021
Abstract Coffee leaf miner (CLM), Leucoptera coffeella, is a key pest of unshaded coffee in hot, dry neotropical production areas. Control is hampered by CLM mining behavior that reduces biological control and pesticide efficacy. Therefore, finding natural enemies that can efficiently control CLM could improve conservation and augmentative biological
