Resumo: 
The bronze bug, Thaumastocoris peregrinus, is an important pest affecting Eucalyptus plantations. The egg parasitoid Cleruchoides noackae was introduced in Brazil in 2012 for biological control of this pest. A mass rearing of C. noackae was established at EMBRAPA Florestas. This paper summarizes the main techniques developed to date in order to maximize the production of adult C. noackae. The use of eggs laid on towel paper strips increased the number of emerging parasitoids when compared to cutouts of Eucalyptus leaves. Host eggs 2 days old are preferred by C. noackae over 3- or 4-day-old ovipostures. Eggs can be stored at 5 ºC for 30 days after being parasitized without signifi cant effects on parasitoid emergence; such storage is a convenient strategy. The mean parasitoid emergence varies signifi cantly with the density of host eggs; an increase in the number of host eggs offered reduced the number of parasitoids that emerged. These improvements have played a signifi cant role in the production of C. noackae that has made possible mass release of C. noackae in Brazil and the establishment of natural populations of the parasitoid, as recently confi rmed.
