Information on the chemical communication system and reproductive ecology of this insect is scant, and it may be relevant for designing management strategies for eucalypt plantations. Adults and nymphs usually aggregate in the field, possibly by means of chemical signals. Males emit large amounts of 3-methyl-2-butenyl butyrate, which attracts conspecific adult males but not females. The ecological role of this putative male aggregation pheromone remains unknown. Here, we report olfactometer bioassays showing that late-instarmale nymphs are also attracted to synthetic 3-methyl-2-butenyl butyrate and to adult male volatile extracts, which contain this compound as the major component. As previously shown for adult females, nymphs that moulted into females were not attracted to either volatile stimulus. The intra-gender attraction of nymphs and adults may be related to the exploitation of food resources, or as a reproductive strategy for newly emerged males. Further studies on the reproductive behaviour and mating system of T. peregrinus will contribute to understanding the ecological significance of male-male, adultnymph attraction, as well as the practical applications that may result from these findings.  aEUCALYPTUS  aAGGREGATION PHEROMONES  aEUCALYPTUS PESTS  aHETEROPTERA  aTHAUMASTOCORIDAE1 aGROBA, H.F.1 aMARTÍNEZ, G.1 aSELLANES, C.1 aROSSINI, C.1 aGONZÁLEZ, A.  tNeotropical Entomology, p. 1?7, 2017.
