ABSTRACT

This paper reports, for the first time, the incidence of the aphids Aphis gossypii Glover, 1877 and Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae) on Ixora macrothyrsa Teijsm. & Binn. (Rubiaceae) in Brazil. The formal records of interaction among Aphis spiraecola Patch, 1914 with Ixora coccinea

L. and Ixora coccinea L. var. compacta Hort. in Brazil, and the presence of Aphelinus gossypii Timberlake, 1923 (Hymenoptera: Aphelinidae), parasitoid of A. spiraecola in the state of São Paulo, are made. Observations on other parasitoids (Hymenoptera) infesting these aphids were also made. The paper includes a short morphological characterization of the aphids, parasitoids, a survey of the ornamental plant hosts in Brazil and suggestions for control.
