Effects of female diet and age on offspring sex ratio of the solitary parasitoid Pachycrepoideus vindemmiae (Rondani) (Hymenoptera, Pteromalidae)

Offspring sex ratio shifts of the solitary parasitoid wasp, Trichopria drosophilae (Hymenoptera: Diapriidae), under local mate competition

“…Trichopria drosophilae produced a greater proportion of sons on the first day of oviposition than on the second to fifth day. This may result from a male-first strategy (Bayram et al 2004, Hu et al 2012; that is, in some species, male offspring tend to be produced at the start of oviposition bouts, followed by mostly females, as seen for some pollinating fig wasps (Kjellberg et al 2005, Raja et al 2008, Hu et al 2013). An egg parasitoid wasp, Telenomus busseolae Gahan (Scelionidae), also has a higher proportion of females with increasing egg mass size (Bayram et al 2004).…”

Effects of Host Age on the Parasitism ofPachycrepoideus vindemmiae(Hymenoptera: Pteromalidae), an Ectoparasitic Pupal Parasitoid ofBactrocera cucurbitae(Diptera: Tephritidae)

“…Hu et al (2012) reported that the percentage of males among the offspring of P. vindemmiae decreased as the female's age increased, but increased again later. Females with poor food quality produced more male offspring.…”

Isolation and characterization of polymorphic microsatellite loci for Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae)

“…Parasitoid wasps and houseflies were reared in a climatic chamber with a light: dark photoperiod (14:10 h). Temperature and relative humidity were 25 ± 1°C and 60 ± 5%, respectively (Hu et al, 2012). Genomic DNA was extracted from ethanol-preserved samples using a standard proteinase K/phenol extraction protocol (Sambrook and Russell, 2001).…”
