The possibility that insects might be involved in the transmission of the fatal yellowing disease in oil palm in Brazil is extremely significant when one suspects the involvement of "virus or viroid" mycoplasma-like organisms (MLO). The probable aerial spread of the disease reinforces this hypothesis. Different species of the Derbidae and Cixiidae families, among them Persis sp. and Myndus crudus, are being tested as part of an effort to transmit the disease to healthy palms through suspected insects. Various types of cages are being used to isolate the plants. Until now a total of 256,712 insects from these two families have been released. No symptoms typical of fatal yellowing have been observed as yet in any of the tests that were developed.
