Table 1. Mean and standard error of the percentage of hosts that contained more than one egg (egg/hst), from which more than one wasp emerged (wasp/hst), and the difference between these values for hybrid females that had mated either with a gregarious male, had remained virgin or had mated with a solitary male.

n >egg/hst >wasps/hst difference

gregarious male 16 38.4 (2.39) 28.7 (2.13) 9.8 (2.93)

virgin 21 33.8 (2.08) 12.3 (1.86) 21.6 (2.56)

solitary male 13 43.1 (2.65) 5.3 (2.36) 37.8 (3.25)

Table 2. Mean and standard error of the total number of offspring (eggs or wasps) and the difference between these numbers, for hybrid females that had mated either with a gregarious male, had remained virgin or had mated with a solitary male.

n >egg/hst >wasps/hst difference

gregarious male 16 60.6 (2.25) 54.8 (1.97) 5.8 (1.95)

virgin 22 57.0 (1.97) 43.2 (1.72) 13.8 (1.71)

solitary male 13 58.8 (2.51) 38.7 (2.19) 20.1 (2.17)

Table 3. Mean and standard error of the number of parasitized hosts indicated by the presence of one or more eggs, by the emergence of one or more wasps and the difference between these numbers, for hybrid females that had mated either with a gregarious male, had remained virgin or had mated with a solitary male.

n hosts with egg host with wasps difference

gregarious male 16 41.6 (1.24) 40.3 (1.40) 1.3 (0.93)

virgin 21 40.9 (1.08) 38.9 (1.22) 2.1 (0.81)

solitary male 13 39.2 (1.37) 37.3 (1.55) 1.9 (1.03)

Table 4. Total egg and wasps distribution per host for females that had either mated with males from a gregarious line, had remained virgin or had mated with males from a solitary line. Egg allocation per host, represented as the percentage of all hosts in egg sample containing either 1, 2, 3 or 4 eggs. Wasp distribution per hosts represented as the percentage of hosts containing a male (M) or a female (F) or a combination of the two.
