Pruett, C.J.H., & Colque, A.E. 1984 The occurrence and distribution of Saccharicoccus sacchari and its parasite Anagyrus saccharicola in sugarcane in the Bolivian orient.. Entomology Newsletter (16): 11-13.
Notes: Saccharococcus sacchari, a common pest of sugarcane, is presumed to have been present in Bolivia since colonial times, though it was not formally recorded from the country until 1982. Currently, the northern limit of its distribution there appears to be from the Andean foothills near San Borja, across the Beni wetlands to the north of the town of Trinidad. It occurs southwards throughout the Precambian shield, east to the Brazilian border and south to San Jose de Chiquitos on the northern edge of the Gran Chaco. It has also been found in Charagua on the north-western edge of the Gran Chaco and directly west into the Andean foothills in the cane-growing areas of Monteagudo. Its natural enemies in Bolivia have been found to include Aspergillus flavus, the predacious coccinellids Hyperaspis trilineata and H. notata and the parasite Anagyrus saccharicola. The parasite appears to have been accidentally introduced into Bolivia; it was not recovered from the other mealybugs found on sugarcane there (Dysmicoccus boninsis and D. brevipes). The 4 natural enemies appear to be holding populations of S. sacchari at reasonably low levels in the main commercial sugarcane-growing areas of Bolivia and it may be advisable to introduce them into areas where the pest is at present less well contained.
