Two exotic parasites of the long‐tailed mealybug Pseudococcus longispinus (Targioni‐Tozzetti), Anarhopus sydneyensis Timberlake and Hungariellaperegrina (Compere), were introduced into Loxton and successfully mass reared on cultures of the mealybug. About 3,000 A. sydneyensis and 40,000 H. peregrina adults were released into field populations of the mealybug in fruit trees along the River Murray in South Australia during 1972 to 1974. In addition several pumpkins infested with mealybugs parasitized by these species were placed in the field. Mealybugs collected from the release trees for a year after release did not yield either species of parasite and it appears that they did not become established.
