“…Honeydew, on the other hand, is frequently exploited by insect parasitoids (Jervis et al, 1996;Wäckers, 2000;Heimpel et al, 2004). It contains amino acids in significant amounts (Gray, 1952;Auclair, 1963;van Vianen, 1982;Cochran, 1985;Crane & Walker, 1986;van Vianen, 1987;Byrne & Miller, 1990), which parasitoids need to sustain oogenesis. In cases of parasitoids attacking Homoptera, searching for honeydew does not reduce the time available to search for hosts (Wäckers, 1994;Takasu & Lewis, 1995), because honeydew is produced by the host and can be directly imbibed from the host anus (Vos, 1995;Zoebelein, 1955;Jervis et al, 1996).…”
