Descripción
Póster y resumen
Numerous pests native to Australia and associated with eucalyptus invaded other countries. The genus Ophelimus has several gall wasps that are continually expanding and causing damage to the eucalyptus plantation. Two species of Ophelimus were detected in Argentina: O. maskelli reported in 2013 with its parasitoid, Closterocerus chamaeleon, and an unidentified species, Ophelimus sp., in 2017. A field survey was carried out in eucalyptus plantations to assess the distribution of Ophelimus spp. and C. chamaeleon. Twenty-one eucalyptus plantations were sampled from 2017 to 2022, covering four provinces in an extensive productive area. Branches (50- 60 cm) with leaves containing developed galls were collected in each plantation. The external morphological aspect of galls was characterized. Adults were identified after emergence according to their morphological characteristics and counted in the laboratory. Ophelimus maskelli develops in a single-cell gall and expands to both sides of the leaf blade; galls are round, green, or red and have a smooth texture. Galls induced by Ophelimus sp. are also nearly round, smaller, and expand only to one leaf surface; they have a brown-grey color and a rough appearance. O. maskelli is present in all provinces sampled in plantations of E. tereticornis, E. camaldulensis, E. grandis, and some hybrids (E. grandis x E. camaldulensis and E. grandis x E. urophylla). Besides, C. chamaeleon was found at all sample sites. About 14.000 adults (gall wasp + parasitoids) were collected and parasitism ranged from 60 to 100 %. Ophelimus sp. was present in Buenos Aires province in E. viminalis and E. cinerea. Adults of C. chamaeleon emerged from galls but in low numbers (parasitism ≤ 0.6 %). In conclusion, O. maskelli has a wide distribution and is always associated with C. chamaeleon, which seems to contribute to the mortality of the population pest. The spread of Ophelimus sp. may represent a threat to eucalyptus plantations in the region. Further molecular studies are needed to identify the pest at the species level. The host range and life cycle of Ophelimus sp. and the role of C. chamaeleon as a biological control agent of this pest also need to be studied
