INCIDENCE AND SEVERITY OF COFFEE LEAF RUST, CERCOSPORIOSIS AND COFFEE LEAF MINER IN COFFEE PROGENIES [PDF]

Coffee Science, 2018
Coffee leaf rust is the main disease of this crop, however cercosporiosis and coffee leaf miner can also cause significant damage when they reach high levels of infestation. Plant genetic improvement for resistance is one of the best tools for controlling plant diseases.

Coffee leaf volatiles and egg laying by the coffee leaf miner Leucoptera coffeella

Crop Protection, 2008
Abstract Recent reports of coffee genotypes resistant to one of its key pests in the Neotropical region, the leaf miner Leucoptera coffeella (Lepidoptera: Lyonetiidae), sparked studies trying to recognize the underlying causes of resistance. An association between increased egg laying by the leaf miner and increased caffeine levels in coffee leaves ...

COFFEE LEAF MINER INCIDENCE AND ITS PREDATION BY WASP IN COFFEE INTERCROPPED WITH RUBBER TREES [PDF]

Coffee Science, 2018
The coffee leaf miner (CLM) Leucoptera coffeella has a wide distribution and causes significant losses in coffee plantations ( Coffea spp. ) in Brazil. Its occurrence can be mitigated in intercropped systems, with the rubber tree ( Hevea brasiliensis ) adapting well to the consortium, while also providing extra income to the producer.

Effect of coffee alkaloids and phenolics on egg-laying by the coffee leaf minerLeucoptera coffeella

Bulletin of Entomological Research, 2008
AbstractThe recognized importance of coffee alkaloids and phenolics mediating insect-plant interactions led to the present investigation aiming to test the hypothesis that the phenolics chlorogenic and caffeic acids and the alkaloid caffeine and some of its derivatives present in coffee leaves affect egg-laying by the coffee leaf minerLeucoptera ...
