Trees of Macadamia spp. growing at Turrialba and other places of Costa Rica are being attacked by bees of the genus Trigona. These bees eat new leaves and tender shoats of the trees causing considerable damage that sometimes results in death of young plants. No reports on such damage have been found in the literature. This may be due to the fact that Trígono, bees only occur in the American Tropics, where Macodamia has not been planted extensively to date.
