“…Besides interacting with viruses in the same host, parasitoids also have the ability to physically transfer baculoviruses between hosts (Caballero et al 1991; Hochberg 1991a; Matthews et al 2004). Females of Apanteles telengai, Aleiodes gasteratus , and Campoletis annulata that previously oviposited in GV-infected A. segetum larvae could transmit the virus to healthy larvae in subsequent ovipositions (Caballero et al 1991).…”

“…For example, M. gyrator was shown to discriminate between healthy and Lacanobia oleracea (L.) granulovirus -infected L. oleracea larvae in greenhouse conditions, and the braconid could mechanically transmit the virus at low levels and decrease pest damage on tomato (Matthews et al 2004). Microplitis pallidipes carrying SeMNPV caused a greater S. exigua population reduction in greenhouse (Jiang et al 2011).…”

“…More specifically, parasitoid survival is largely dependent on the time of virus inoculation and the dose of virus. The survival of M. gyrator within a Lacanobia oleracea (L.) granulovirus (LoGV)-infected host increased as the interval between parasitism and infection increased, and no parasitoids emerged from hosts infected with Lacanobia oleracea (L.) granulovirus before parasitoid oviposition (Matthews et al 2004). The parasitoids M. demolitor, Cotesia kazak , and Hyposoter didymator required a time advantage of 3 days before the host was exposed to NPV to successfully complete their development (Murray et al 1995).…”

Baculoviruses may interact with parasitoids in the same host. A previous study has shown that infection of larvae with Spodoptera litura nucleopolyhedrovirus (SpltNPV) was deleterious to the survival and development of Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae). In this paper, the interactions between M. pulchricornis and Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) in Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), a permissive host of the virus and parasitoid, were investigated. The results showed that the effect of M. pulchricornis on SeMNPV and the effect of the virus on the parasitoid both depended on the concentration of the virus and the interval between viral infection and parasitism. Whether S. exigua was treated with the parasitoid and virus simultaneously or 1 day apart, the biological activities of 105, 106, and 107 OBs/mL SeMNPV were all significantly improved by M. pulchricornis. In contrast, the biological activity of 103 OBs/mL SeMNPV was significantly decreased when the host was exposed to the virus and parasitoid simultaneously. Regarding the impact of SeMNPV on M. pulchricornis, exposing the host to the parasitoid and SeMNPV with concentrations lower than 106 occlusion bodies (OBs)/mL produced no negative effects on the parasitoid. The results also showed that ingestion of SeMNPV by adult stage M. pulchricornis significantly increased the number of parasitoid offspring that successfully emerged from the host. Furthermore, M. pulchricornis was found to transmit SeMNPV among populations of S. exigua. Taken together, these findings indicate that M. pulchricornis integrated with an appropriate concentration of SeMNPV has the potential to improve the efficacy of biological control against S. exigua.

“…Research to date has shown that many, although not all, hymenopteran parasitoids are able to discriminate to varying degrees, between infected and non-infected hosts(8,16,17,35). For example, both Venturia canescens and Meteorus gyrator females were shown to reduce the number of eggs that they inserted into betabaculovirus-infected Indian meal moth, Plodia interpunctella and Lacanobia oleracea larvae, respectively, based on the level of the host=s infection(38,45).…”
