de Jong, P.W., & van Alphen, J.J.M. 1988 Host size selection by Leptomastix dactylopii Howard, a parasitoid of Planococcus citri (Risso), a functional interpretation.. Mededelingen van de Faculteit Landbouwwetenschappen, Rijksuniversiteit Gent 53(3a): 1079-1096.

Notes: [In XXXX International Symposium on Crop Protection, Gent.] Host size selection and sex allocation in the encyrtid Leptomastix dactylopii, a parasitoid of the pseudococcid Planococcus citri, were studied in the laboratory to determine whether invulnerable size classes exist and to establish whether the size range of hosts attacked differs from that of Leptomastidea abnormis. L. dactylopii attacked mainly the larger host sizes (3rd- and 4th-instar nymphs and reproducing females). Proportionally more female parasitoids were reared from larger hosts (4th-instar nymphs and reproducing females), while predominately male parasitoids were reared from smaller 4th- and 3rd-instars.
