鳳梨粉介殼蟲(Dysmicoccus brevipis CKll.)及鳳梨赤蝨(Stigmaeus flouridanus Banks)為鳳梨之主要害蟲，蔓延廣泛，為害甚烈，頗為一般人所重視，蓋因鳳梨粉介殼蟲能傳播毒素，引起鳳梨急性萎凋病之發生，而鳳梨赤蝨與急性萎凋病之關係，雖尚無定論，然因其寄生，而致生長不良，似可斷言。
As in other parts of the world, the mealybug (Dysmicoccus brevies Ckll.) and red-mite (Stigmaeus floidanus Banks) constitute the commonest and most important pests of pineapple in Formosa. In April 24 to May 29, 1952, inclusive, an intensive field survey of these two pests was made at 11 cultivating centers in southern and central parts of this island. Totally 28 plots (517 plants) representing different environmental conditions were sampled at random and immediately following this, the actual number of mealybug adults and nymphs on different parts of the plants were counted.
