Conteúdo: 	In the routine indexing of cachexia on Parson's special mandarin, irregularities and inconsistencies of symptom expression were found. In most cases these seemed to be associated with co-infection of the original explant with exocortis. Therefore the hypothesis of an interaction between exocortis and cachexia agents was considered. An experiment was carried out by co-inoculating on Parson's special mandarin a pure cachexia isolate (X-701) and three different exocortis sources, previously characterized as severe (E-117), moderate (E-111) and mild (E-140) according to their reaction on Etrog citron. The results indicated that E-117 and E-111 interfered with cachexia symptom expression. None of the plants inoculated with X-701 and E-117 or E-111 showed  cachexia symptoms, whereas all plants inoculated with X-701 alone or in combination with E-140 gave positive reactions. These results indicate that certain citrus viroids or viroid combinations may symptom expression of cachexia.
