Two newly established primary parasites, Leptomastix dactylopii Howard and Anagyrus sp., found attacking Planococcus citri (Risso) in Texas.
During examination of grapefruit and lime (Citrus aurantifolia) trees in a residential area of Weslaco, Texas, in 1977 for the citrus pest Planococcus citri (Risso), 2 primary parasites, Leptomastix dactylopii How., which had been introduced from California in 1970 but had not been subsequently recovered in Texas, and Anagyrus sp., which had not previously been recorded on P. citri in Texas, were both found attacking this pest. L. dactylopii was the most abundant parasite in mid-August, parasitising 20.7% of P. citri; Pauridia peregrina Timb., an indigenous parasite, parasitised 48.5% and was the most abundant species in late August; and Anagyrus sp. parasitised only 4.3% but was the only parasite recovered from Planococcus citri in mid-September. A hyperparasite, Prochiloneurus dactylopii (How.), was found attacking the primary parasite complex of Planococcus citri in mid-August at the rate of 1%. The rich parasite complex recovered from P. citri in this residential area is thought to be related to use of little or no chemical insecticides.
