Refrigerated Eggs of Riptortus pedestris (Hemiptera: Alydidae) Added to Aggregation Pheromone Traps Increase Field Parasitism in Soybean

Quality assessment of Riptortus pedestris (Hemiptera: Alydidae) eggs cold-stored at different temperature and relative humidity regime

“…The storage of host eggs in a state suitable for successful development of an endoparasitoid is important both for the mass rearing of natural enemies and to build up the population of natural enemies in the field by mass releasing host eggs when hosts (in the form of natural host eggs) is limiting in the field (Chen and Leopold, 2007). Various studies have found that cold-stored host eggs of various bugs, including R. pedestris could be successfully parasitized by egg parasitoids (Popov, 1974;Corrêa-Ferreira and Moscardi, 1993;Mahmoud and Lim, 2007), and cold-stored host eggs of R. pedestris have been released to increase field parasitism (Lim and Mahmoud, 2009;Alim and Lim, 2011).…”

“…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).…”

Hadronotus pubescens (Motschoulsky) (Hymenoptera, Scelionidae): Redescription, biological attributes, and parasitism on eggs of Riptortus pedestris (Fab.) (Hemiptera, Alydidae)

“…In light of these difficulties, cultural practices such as delayed seeding and use of resistant varieties have been suggested for the management of various stink bugs (Bowers 1990;Wada et al 2006). Biological control has been successfully employed against various stink bugs by introduction or augmentation of egg parasitoids (Weber et al 1996;Orr 1998;Alim and Lim 2011) and may be an option for R. pedestris in Bangladesh.…”
