A SURVEY OF FALL ARMYWORM (LEPIDOPTERA: NOCTUIDAE) PARASITOIDS IN THE MEXICAN STATES OF MICHOACÁN, COLIMA, JALISCO, AND TAMAULIPAS
TLDR
The greater diversity of parasitoids and higher rates of parasitism in Michoacan may be related to the more diverse habitat with more forests, orchards, and pastures near the cornfields in that state. Expand
Effects of a Nonoccluded Virus of Spodoptera frugiperda (Lepidoptera: Noctuidae) on the Development of a Parasitoid, Cotesia marginiventris (Hymenoptera: Braconidae)
TLDR
Fewer parasitoid larvae were found in virus-infected hosts than in parasitized controls when host larvae were dissected 6 days after parasitization, and mortality was not due to the virus killing the host before the parasitoids could complete development. Expand
Sunlight Persistence and Rainfastness of Spray-Dried Formulations of Baculovirus Isolated From Anagrapha falcifera (Lepidoptera: Noctuidae)
TLDR
It is demonstrated that formulations made with natural ingredients could improve persistence of virus-based biopesticides if improved formulations can prevent rapid loss of insecticidal activity from environmental conditions such as sunlight and rainfall. Expand
Oviposition Day Effect on Incidence of Agonadal Progeny of Helicoverpa zea (Lepidoptera: Noctuidae) Infected with a Virus
TLDR
An agonadal condition of moths in a laboratory colony of corn earworm, Helicoverpa zea (Boddie), was studied and there was an increase in the incidence of agonadal progeny with progressive oviposition day of infected female parents. Expand
Infectivity of Fall Armyworm (Lepidoptera: Noctuidae) Nuclear Polyhedrosis Virus Enhanced by a Fluorescent Brightener
Studies were designed to determine the effect of the optical brightener, Tinopal LPW, on the infectivity of two preparations each of two isolates of the fall armyworm, Spodoptera frugiperda (J. E.Expand
Incidence and host range of a new ascovirus isolated from fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae)
TLDR
A new virus disease caused by an ascovirus was found in larvae of the fall armyworm, Spodoptera frugiperda, collected in south Florida and Georgia and failed to produce a persistently high rate of infection by this route. Expand
Comparative virogenesis of filamentous virus and polydnavirus in the female reproductive tract of Cotesia marginibentris (Hymenoptera: Braconidae)
Abstract A nonoccluded filamentous virus (CmFV) was found in the reproductive tract of females in two of five laboratory colonies of Cotesia marginiventris established from parasitized lepidopteranExpand
Analysis of the Spodoptera frugiperda Nuclear Polyhedrosis Virus Genome by Restriction Endonucleases and Electron Microscopy
Restriction endonuclease analysis was used to differentiate between four strains of Spodoptera frugiperda nuclear polyhedrosis virus from different geographical areas. In addition, partialExpand
Biological Differences Between Five Populations of Fall Armyworm (Lepidoptera: Noctuidae) Collected from Corn in Mexico
TLDR
Results suggest that two corn FAW strains may have developed reproductive isolation due to geographic isolation, as the two strains produce no progeny when paired. Expand
Interactions in Entomology: Enhanced Infectivity of Entomopathogenic Viruses by Fluorescent Brighteners
TLDR
The enhanced infectivity produced by the fluorescent brighteners generally resulted in earlier mortality and in some cases extended infectivity of the virus to older instars and in a few cases the host range was extended. Expand
