“…Several techniques have been used to optimize the large-scale mass production of parasitoids in laboratories. Some of these approaches include, the in vitro development of parasitoids (Strand et al ., 1988; Nettles, 1990; Consoli and Vinson, 2004; Shirazi, 2006; Paladino et al ., 2010; Kim et al ., 2018), cold storage of parasitized hosts (Noble, 1937; Dass and Ram, 1983; Gautam, 1986; Ganteaume et al ., 1995 a , 1995 b ; Bayram et al ., 2005; Liu et al ., 2014; Tunca et al ., 2014; Kidane et al ., 2015), cold storage of parasitoids as pupae or adults (Gautam, 1986; Foerster et al ., 2004; Foerster and Doetzer, 2006; Yılmaz et al ., 2007; Mousapour et al ., 2014; Afshari and Nazari Fandokht, 2019; Cira et al ., 2021) and cold storage of unparasitized hosts (Corrêa-Ferreira and Moscardi, 1993; Kıvan and Kılıç, 2005; Mahmoud and Lim, 2007; Alim and Lim, 2011; Spínola-Filho et al ., 2014; Singhamuni et al ., 2015; Wong et al ., 2021).…”

Ooencyrtus pityocampae and Ooencyrtus kuvanae are egg parasitoids that are considered potential candidates for the control of different pest species through inundative release. The aim of this study was to assess the effects of different cold-storage periods of Philosamia ricini eggs (host) on the rearing parameters of O. pityocampae and O. kuvanae. Host eggs were stored at 3 °C, and a factorial experiment involving two parasitoid species, nine host storage periods (1, 5, 10, 15, 30, 45, 60, 75 and 90 days) and a control, and two host ages (1 and 2 days) was conducted, with 10 replications including 40-P. ricini eggs each. Adult emergence, development time, longevity, and fecundity were investigated. The parasitoid adult emergence percentage significantly varied with storage duration. These values were lower in O. kuvanae than in O. pityocampae. The development time of O. kuvanae progeny increased in both host age groups except in the 1-day storage period subgroup. However, the development times of the progeny of O. pityocampae reared on one-day-old eggs stored for 5, 10, 60, and 75 days were increased, and the development times of the progeny of O. pityocampae reared on 2-day-old eggs stored for 45 and 90 days were increased. The longevity of the F1 progeny of O. kuvanae was negatively affected by storage time. There was no difference in the longevity of the F1 progeny of O. pityocampae compared to that of the control. Additionally, the fecundities of the F1 progeny of O. pityocampae and O. kuvanae were 54.7 and 47.0 offspring/female, respectively. These results provide useful information for guiding the development of mass rearing methodologies for both parasitoid species.
