“…Differences in pathology and/or in the morphology of the virus or the polyhedral inclusion bodies (PIB) can occur during propagation in different hosts (Hunter et al, 1973;Vail & Jay, 1973;Tompkins et al, 1981). Continuous propagation of baculoviruses in tissue culture can also result in morphological changes in the virus and/or in pathogenicity (Hink & Vail, 1973 ;Ramoska & Hink, 1974;Mackinnon et al, 1974;Knudson & Harrap, 1976;Potter et al, 1976Potter et al, , 1978.…”

SUMMARYSpodoptera frugiperda nuclear polyhedrosis virus was highly pathogenic to both S. frugiperda and S. exigua. Plaque-purified variants from two of the original isolates showed much greater differences in pathogenicity to the two insect species than the original isolates. Plaque-purified variants from one of the isolates (D) nearly lost pathogenicity for S. exigua while remaining pathogenic for S. frugiperda. Some of the plaque-purified variants produced atypical symptoms, even in S. frugiperda. These variants did not liquefy larvae and release polyhedra when the larvae died as is typical for nuclear polyhedrosis infections in Lepidoptera. These variants also produced fewer polyhedra per g larval weight and often had fewer virions per polyhedron. Light and electron microscopical studies of S. frugiperda and S. exigua infected with one of the original isolates (A) and two of the plaque-purified variants (B2 and D7) indicated that only S.frugiperda infected with isolate A had the highly productive infection and viral morphogenesis typical of nuclear polyhedrosis viruses. Exposure of S. frugiperda to isolate B2 or D7 resulted in a slightly delayed infection characterized by increased amounts of abnormal viral morphogenesis and polyhedra of decreased size. S. exigua infected with isolate A or B2 had greatly reduced and delayed infections that were accompanied by highly variable abnormal viral morphogenesis; virtually no normal polyhedra were produced in these instances. Isolate D7 produced neither nucleocapsids nor polyhedra in S. exigua. Large paracrystalline aggregates of nucleocapsids were common in S. J?ugiperda infected with isolates B2 or D7 and in S. exigua infected by isolate A. Infection of S. exigua by isolate A or B2 was typified by the accumulation of large amounts of excess envelope membrane in the form of strands and vesicles of various sizes. Normal virogenic stromata were characteristics only of S. frugiperda infected with isolate A or B2. Polyhedra produced in S. exigua by even the most pathogenic isolates (A and B2) contained few if any normal virions and were not infective for either S. frugiperda or S. exigua.

“…Adams and Wilcox (1968) studied the histopathology and ultrastructure of the virusinfected tisues of E. cautella. Hunter et al (1973b) showed that NPV isolated from E. cautella was cross-infective to P. interpunctella. Thompson and Redlinger (1968) noted that NPV virions isolated from E. cautella measured 21-32 × 235-300 nm; Hunter et al (1973b) recorded similar-sized virions of 30 (25-40) × 220 (198-262) nm in E. cautella and 32 (25-42) × 227 (200-250) nm in P. interpunctella.…”

Distribution and Occurrence of Vairimorpha plodiae (Opisthokonta: Microspora) in the Indian Meal Moth, Plodia interpunctella (Lepidoptera: Pyralidae) Populations: An Extensive Field Study

The Indian meal moth, Plodia interpunctella (Lepidoptera: Pyralidae) is one of the most important stored product pests. Fumigation plays a significant role in the management of insect pests in stored-products. However, the use of fumigants is problematic because of their effects on the environment and high costs. Entomopathogenic organisms are environmentally friendly control agents and suppress pest populations under natural conditions. In this study, distribution and occurrence of a microsporidian pathogen, Vairimorpha plodiae (Opisthokonta: Microspora) in the populations of P. interpunctella from 12 localities representing Turkey between 2019 and 2020 are presented for the first time by confirming its effectiveness on natural populations. The presence of the microsporidian pathogen was found in 11 of 12 (91.7%) populations. In total, 863 of 3,044 samples were infected by the pathogen. Infection mean was 28.4% for all populations. Our results showed that V. plodiae infection reached to a considerably high prevalence (88.77%) in P. interpunctella populations and varied from 5.1 to 88.7% between the populations. In addition, microsporidia infections have been identified throughout Turkey. We found that V. plodiae can infect all life stages of P. interpunctella. Totally, 623 (28.5%) of 2187 larvae, 14 (37.8%) of 37 pupae, 226 (27%) of 820 adults were found to be infected by the pathogen. There were considerable differences between the dead and living larvae. The microsporidian infection was found in 26 (11.6%) of 225 living larvae, whereas it was found in 595 (30.5%) of 1,952 dead larvae. These results confirm that the microsporidia pathogen has a high spreading potential in P. interpunctella populations and can be a natural biological suppression factor on pest populations.
