Carter, W. 1932a Border plantings as guard rows in pineapple mealy bug control.. Journal of Economic Entomology 25: 1027-1030.

Notes: The planting of several beds of pineapple plants in a strip parallel to the edge of fields and separated from the main plantation by a road is proving essential to economical spraying against Pseudococcus brevipes Ckl. These borders serve as guard rows against too rapid a movement of Pseudococcus brevipes into the field and at the same time localize the area to be regularly sprayed.
