Carter, W., & Ito, K. 1956 Study of the value of pineapple plants as sources of the mealybug wilt factor.. Phytopathology 46: 662-666.

Notes: The value of pineapple plants as sources of the mealybug wilt factor was tested over a period of two growth cycles. One hundred families from six clones were distributed in six different locations on the Island of Oahu. There were six tests made in the first cycle and seven in the second. Most of the positive sources occurred in the resistant clones; only in a few instances were positive sources found in susceptible clones. The data indicate that the mealybug wilt factor is a fluctuating latent factor limited to certain plants and modified only slightly by local environmental and agronomic conditions.
