Searching Behaviour of Metaphycus helvolus, (Compere) and Scutellista cyanea, Motschulsky on Hemispherical Scale, S. coffeae (Walker)

The host searching of Metaphycus helvolus and Scutellisa cyanea were studied under two different constant temperatures of18 °Cand 26 °C. In the course of host-searching, both parasitoids were involved with host-drilling, handling, preening, walking and resting. Host-feeding only occurred with M. h...
