“…Dibrachys boarmiae generally attacks the prepupae and young pupae of cocoon-spinning host species (Gülel 1982;Uçkan & Gülel, 2002;Mehrnejad, 2003; Sarikaya & Gülel, Table 3. The effect of stage and size of host, Galleria mellonella, on clutch size (mean ± SE) and sex ratio (proportion of male) of Dibrachys boarmiae.…”

“…In the current study, the authors found the same sex ratio to be 4:1, thus corroborating Gülel's (1982) findings. As stated by Mehrnejad (2003), the difference between findings may be due to the differences in experimental conditions or parasitoid strain.…”

“…The differences in clutch size per female of the three host species in the current study, therefore, Effects of host species, stage and size on sex ratio and clutch size of a parasitoid may be attributable to the hosts supplying different levels of nutrition in terms of both quality and quantity. Mehrnejad (2003) found in a study conducted with D. boarmiae that the (female:male) ratio in the offspring of the parasitoid reared on G. mellonella was 11.5:1. This was in contrast to the ratio of 4:1 reported by Gülel (1982).…”

Effects of host species, stage and size on clutch size and sex ratio of the gregarious, idiobiont ectoparasitoid Dibrachys boarmiae were investigated at 25±2°C and 70±5% relative humidity. The greater wax moth, Galleria mellonella, small wax moth, Achroia grisella, and early stage solitary larvae of the endoparasitoid, Apanteles galleriae, were used as hosts. Clutch size was greatest from prepupae of the largest host, Galleria mellonella, with a mean of 40.07 offspring per host versus 14.73 and 2.93 for Achroia grisella and Apanteles galleriae, respectively. The mean clutch size from pupae was lower than from prepupae, being 17.27, 10.73 and 2.89 for Galleria mellonella, Achroia grisella and Apanteles galleriae, respectively. Within each host species and stage, heavier hosts resulted in larger clutches. The sex ratio of offspring (proportion of male) was approximately 0.20, with only minor differences among host species, stages and sizes.
