A New Broad Host Spectrum Nuclear Polyhedrosis Virus Isolated from a Celery Looper, Anagrapha falcifera (Kirby), (Lepidoptera: Noctuidae)

Comparative analysis of the genomes of Rachiplusia ou and Autographa californica multiple nucleopolyhedroviruses

“…The sequence of the EcoRI-G restriction fragment of RoMNPV (R1 strain) confirmed that a high degree of nucleotide sequence identity exists between RoMNPV and AcMNPV in this region (Harrison & Bonning, 1999). In addition, the RoMNPV EcoRI-G sequence was found to be almost completely identical to the sequence of the corresponding region in Anagrapha falcifera MNPV (AfMNPV; Federici & Hice, 1997), which was first identified in 1985 (Hostetter & Puttler, 1991). Restriction enzyme analysis and bioassays against three different host species demonstrated that AfMNPV and RoMNPV are isolates of the same virus (Harrison & Bonning, 1999).…”

“…Both AcMNPV and RoMNPV/AfMNPV are known to infect a relatively large number of lepidopteran species (31 and 43 species, respectively; Granados & Williams, 1986;Payne, 1986;Hostetter & Puttler, 1991). Although the host ranges for these viruses overlap, there are significant differences in the abilities of AcMNPV and RoMNPV/AfMNPV to infect and kill several agricultural pest species.…”

“…Helicoverpa zea, is approximately 2?5-to 29-fold more susceptible to RoMNPV/AfMNPV than AcMNPV (Harrison & Bonning, 1999;Hostetter & Puttler, 1991). Ostrinia nubilalis, the European corn borer, is approximately 5-to 11-fold more susceptible to RoMNPV than AcMNPV (Harrison & Bonning, 1999;Lewis & Johnson, 1982).…”

“…The navel orangeworm, Amyelois transitella, is non-permissive to AcMNPV but can be infected and killed with AfMNPV (Vail et al, 1993;Cardenas et al, 1997). The tobacco hornworm, Manduca sexta, a species that is highly refractory to AcMNPV (Washburn et al, 2000), is susceptible to a dose of 100 polyhedra mm 22 diet surface of AfMNPV (Hostetter & Puttler, 1991). The fall armyworm, Spodoptera frugipera, and the velvet bean caterpillar Anticarsia gemmatalis, are also more susceptible to AfMNPV than AcMNPV (Hostetter & Puttler, 1991).…”

A brief review of the past use of baculoviruses for the management of eruptive forest defoliators and recent developments on a sawfly virus in Canada

“…A pest management program was developed by the Canadian Forest Service to examine the potential of NeabNPV, a baculovirus isolated from the balsam fir sawfly in Newfoundland, for biological control of the pine false webworm. Ingestion of baculovirus OBs from a baculovirus has been known to sometimes induce mortality in closely related species (e.g., Gröner 1986, Doyle et al 1990, Hostetter and Puttler 1991, Cory 2000. Indeed, laboratory bioassays using a dropletfeeding method (van Frankenhuyzen et al 1997) indicated that the ingestion of a dose of 1 ϫ 10 6 OBs of NeabNPV by third-instar larvae of the pine false webworm reduced survival to the ultimate larval stadium by 51% compared with larvae that had ingested water only .…”
