• Resumen

  • Galls are of frequent occurrence on Prosopis alba (Griseb.), both in native woodland and in productive systems nurseries and plantations). They have been very little researched in this region. It is very important to undertake this work, so as to gain information useful for planning the cultivation management of this native species. The aim of this study is to classify galls which develop on P. alba in nurseries and plantations, characterize them, link them to the inducing organisms and find out their main growing seasons. Fortnightly inspections were carried out in nurseries and plantations in the province of Santiago del Estero, Argentina, between 2000 and 2006. Seventeen types of gall, found on different organs of the plant, were registered, with greater impact in the nurseries than the plantations. The gall-inducing insects were of the orders Homoptera, Lepidoptera, Diptera, Hymenoptera and Coleoptera. Two species of Hymenoptera new to Santiago del Estero were found.
