The presently recognized biotypes of the greenbug, Schizaphis graminurn (Rondani 1852), have been characterized primarily on the basis of the insects' performance and injurious effects on different cultivars of their graminaceous host plants (Kindler & Spomer 1986). Some of these biotypes have also been shown to differ in several physiological and behavioural attributes, e g insecticide resistance (Teetes et al 1975), feeding behaviour (Montllor et al 1983), enzyme levels (Campbell & Dreyer 1985), polymorphic responses to photoperiod (Eisenbach & Mittler 1987 a), and sex-pheromone recognition (Eisenbach & Mittler 1987b). The present study compares the developmental rate and hatching success of eggs derived from crosses within and between biotypes E and C of the aphid.
