Larvae of noctuids were inoculatedper os with spores of a species ofPleistophora isolated fromAgrotis exclamationis (L.). The mean median lethal dose for mainly 3rd instar larvae ofA. exclamationis was 1.38×105 spores per larva accumulating 34 or 35 days after inoculation and the mean slope for the regression of mortality on dose was 0.82. Third instar larvae ofA. exclamationis andSpodoptera frugiperda (J.E. Smith) inoculated with 2.5×104 spores gained weight quicker than uninfected ones until…

Studies of the pathogenicity of a cytoplasmic polyhedrosis virus isolated from Noctua pronuba (L.) (Lepid., Noctuidae)
TLDR
Third and fourth instar larvae of Noctua pronuba (L.) were inoculated per os with polyhedral inclusion bodies (PIB's) of a cytoplasmic polyhedrosis virus (CPV) isolated from N. pronuba, finding this isolate of CPV is of low pathogenicity and causes only a chronic infection it is unsuitable for use against N. pronounceuba in Britain where rapid control is required.
Feeding behavior of some phytoseiid predators on the broad mite,Polyphagotarsonemus latus [Acari: Phytoseiidae, Tarsonemidae]
TLDR
Feeding behavior of 4 phytoseiid species on the broad mitePolyphagotarsonemus latus (Banks) was studied, and Euseius stipulatus Athias-Henriot fed on all but the nymphal stage, and showed a decreased preference for prey larvae and females.

Nosema whitei, a microsporidan pathogen of some species ofTribolium
TLDR
Adults, emerging fromNosema free larvae, became infected only when exposed to a very high dose (2×1010 spores/g for 14 days from the day of emergence) and infected larvae were treated for 1 hr at 45°C in an attempt to cure the infection.
Dosage effect study of the microsporidian Octosporea muscaedomesticae in the adult black blowfly Phormia regina, with reference to the reproductive cycle of the pathogen.
TLDR
The quantitative pathogenicity of the microsporidian Octosporea muscaedomesticae in adult Phormia regina was studied and it was found that an appreciable number of spores in the inoculum is needed to initiate frank infection.
Nosema whitei, a microsporidan pathogen of some species ofTribolium V. Comparative pathogenicity and host range
TLDR
A dose-mortality technique was used to compare the pathogenicity of Nosema whitei for 4 stored products pests, finding that T. anaphe was at least 100 times more susceptible than the other species tested, while Tenebrio molitor, Palorus ratzburgi andPlodia interpunctella were refractile to infection.
Nosema whitei, a microsporidan pathogen of some species of Tribolium: III. Effect on T. castaneum☆☆☆
TLDR
In the final experiment infection was shown to reduce adult fecundity, though the viability of the eggs was not affected and no trans-ovum transmission of infection occurred.
Quantitative studies on the pathogenicity of Nosema carpocapsae, a microsporidian pathogen of the codling moth, Cydia pomonella, in New Zealand
TLDR
The pathogenicity of Nosema carpocapsae for codling moth was studied using dose-infectivity experiments and infected eggs were not produced by healthy females mated with infected males, although such pairs generally produced fewer eggs than healthy pairs.
The natural incidence of disease in the cutworm Agrotis segetum in England and Wales
TLDR
Soil-dwelling noctuids, mostly cutworm larvae were collected from various arable crops, from 39 sites in England and Wales between 1975 and 1978, and the possibility of controlling cutworms with their pathogens is discussed.
A survey of cutworm attacks in England and Wales, and a descriptive population model for Agrotis segetum (Lepidoptera: Noctuidae)
TLDR
A model suggests that weather conditions alone were responsible for the last major cutworm outbreak in 1976, and an index of larval survival to third instar is estimated, based on temperature-rate of development relationships and mortality due to daily rainfall.
Microsporidia in Invertebrates: Host-Parasite Relations at the Organismal Level
TLDR
My experience in distribution of microsporidia of invertebrate hosts indicates that there may be a microspora in every living invertebrates, and the extreme care is necessary to record all characteristics.
The preservation of infective microsporidan spores
Abstract The median infective doses (ID50) of spores of Nosema apis preserved at −20°C within the tissues of freshly killed infected bees were 21, 41, and 157 after 0, 12, and 24 months,
