Conteúdo: 	Observations and data on the etiology of mealybutg wilt are presented. Symptom expression can conveniently be designated in 4 progressive stages and 1 recovery stage. Limited expression of symptoms may occur and 1 or 2 leaves only be affected if the period for the development of symptoms is prolonged. The period for the development of symptoms, which varied from 43 to 295 days, is affected by the age of the plant at time of infestation. Recovery from advanced stages of wilt occurs but that from first estage wilt can occur with complete loss of symptoms. Recovery may also be affected by N fertilization but the age of the plant at time of infestation is a factor. Frequent mealybug infestation adversely affects recovery. There is additional evidence that mass action is a factor and that sub-wilting mealybug colonies, when joined, will cause wilt.
