Wolcott, G. N. (1953). Biological control of the pustule scale in Puerto Rico. The Journal of Agriculture of the University of Puerto Rico, 37(3), 228–233. https://doi.org/10.46429/jaupr.v37i3.12752
Abstract
The perfection of biological control results in only apparent extermination for a period of years. The pustule scale, Asterolecanium pustulans Cockerell, so eagerly eaten by the introduced twice-stabbed ladybeetle, Chilocorus cacti Linnaeus, as to result in its complete disappearance, appeared again in Puerto Rico after 12 years.Downloads
