The predatory effect of two species of Chrysoperla [Chrysoperla carnea (Stephens) and C. rufilabris (Burmeister)] was evaluated against citrus thrips, Scritothrips citric (Moulton), at the Three Flags Mango Ranch near Salton City, California, U. S. A. For both species the early release of 50 larvae/ tree failed to cause any reduction in thrips number but treatment of 100 and 200 larvae/ tree for both species and 1,000 eggs of C. rufilabris resulted in significantly lower thrips numbers for 1-2 post release samples.
