Host acceptance and host suitability of the cotton aphid,
Aphis gossypii for an indigenous parasitoid,
Lysiphlebus japonicus were investigated in the laboratory and compared with those for a commercially introduced parasitoid,
Aphidius colemani.
L. japonicus attacked 2-, 4- and 6-day-old aphids, but not 0-day-old ones. The rate of oviposition occurrence after attacking hosts was not significantly different between
L. japonicus and
A. colemani. However, the survival rate of
L. japonicus larvae in the hosts was significantly lower than that of
A. colemani. This suggests the low suitability of
A. gossypii as a host of
L. japonicus.
