De Barro, P.J. 1991 Sampling strategies for above and below ground populations of Saccharicoccus sacchari (Cockerell) (Hemiptera, Pseudococcidae) on sugarcane.. Journal of the Australian Entomological Society 30: 19-20, Part 1.

Notes: A flotation method using stubble pieces of sugarcane was more efficient in sampling underground sugarcane mealybugs, Saccharicoccus sacchari than were flotation using stools or cores or the dry probe method using stools, cores or single-stalk stubble pieces. Above-ground populations were distributed randomly within a stool. Total number of mealybugs per sample could be estimated from the number of adults per sample.
