1. The transmission of an insect pathogen by cannibalism was studied by a series of choice and no‐choice experiments. 
Age‐related cannibalism and horizontal transmission of a nuclear polyhedrosis virus in larval Spodoptera frugiperda
1. Experiments were carried out to investigate the incidence of cannibalism throughout the larval development of the noctuid moth Spodoptera frugiperda, and to examine the risk of infection fromExpand
Costs of cannibalism in the presence of an iridovirus pathogen of Spodoptera frugiperda
TLDR
The hypothesis of a positive correlation between insect density and the likelihood of disease transmission by cannibalism was examined in laboratory microcosms and a field experiment. Expand
Dynamics of cannibalism in equal‐aged cohorts of Spodoptera frugiperda
TLDR
Antagonistic interactions in herbivorous insects are often density‐dependent, so rates are predicted to vary dynamically over time as density changes, and fatal intraspecific interactions in young first‐ and second‐instar Spodoptera frugiperda are studied. Expand
Causes and consequences of cannibalism in noncarnivorous insects.
TLDR
Cannibalism can be adaptive by improving growth rate, survivorship, vigor, longevity, and fecundity, and it also can play an important role in regulating population density and suppressing population outbreaks, stabilizing host plant-insect relationships, and reducing parasitism rates. Expand
Density-independent resource limitation and the transmission of an insect pathogen
TLDR
The effects of resource limitation on the transmission of a pathogen were explored by replacing part of the host’s diet with an indigestible bulking agent and the implications of resource levels to the population dynamics of host-pathogen interactions are discussed. Expand
Effects of resource quality on the population dynamics of the Indian meal moth Plodiainterpunctella and its granulovirus
TLDR
Investigating the impact of resource-dependent host patterns of abundance on pathogen dynamics and prevalence in coexisting populations of P. interpunctella found cyclic fluctuations in the proportion of infected larvae were related to cycles in the age structure of the larval population. Expand
Navigating infection risk during oviposition and cannibalistic foraging in a holometabolous insect
TLDR
It is tested experimentally whether fruit flies avoided infected food sources when foraging as larva and deciding where to lay eggs as adults and whether mothers sometimes avoided laying eggs on infectious food. Expand
Determinant Factors in the Production of a Co-Occluded Binary Mixture of Helicoverpa armigera Alphabaculovirus (HearNPV) Genotypes with Desirable Insecticidal Characteristics
TLDR
It is concluded that the efficient production of HearSP1B+HearLB6 OBs involves inoculation of recently molted fifth instars with a LC80 concentration of OBs followed by individual rearing at 30°C, which indicates that insects requireindividual rearing to avoid major losses in OB production. Expand
Disease transmission by cannibalism: rare event or common occurrence?
TLDR
It is shown that group cannibalism, i.e. shared consumption of victims, is a necessary condition for disease spread by cannibalism in the absence of alternative transmission modes, consistent with a review of the literature showing that diseases transmitted by cannibalisms are infrequent in animals, even though both cannibalism and trophic transmission are very common. Expand
Baculovirus-Induced Climbing Behavior Favors Intraspecific Necrophagy and Efficient Disease Transmission in Spodoptera exigua
TLDR
It is concluded that, in addition to improving the dissemination of virus particles over plant foliage, baculovirus-induced climbing behavior increases the incidence of intraspecific necrophagy in S. exigua, which is the most efficient mechanism of transmission of this lethal pathogen. Expand

1. Theoretical studies suggest that disease may play an important role in the population dynamics of insects, but there have been no long-term empirical studies that have examined this interaction inExpand
Resource limitation and the lethal and sublethal effects of a viral pathogen in the Indian meal moth, Plodia interpunctella
TLDR
The balance between deleterious sublethal effects of the virus and the selection of more robust individuals by the bioassays is proposed as a mechanism to explain variation in the effects of resource limitation and the lethal and sub lethal effects of a granulosis virus on a lepidopteran host. Expand
The effects of a sublethal baculovirus infection in the Indian meal moth, Plodia interpunctella
TLDR
Using an improved bioassay technique, significant sublethal effects have been unequivocally demonstrated in the development rate and reproductive capacity of the host for the first time. Expand
Transmission dynamics of Bacillus thuringiensis infecting Plodia interpunctella: a test of the mass action assumption with an insect pathogen
TLDR
Transmission was found to increase in a more than linear way with host density in fourth and fifth instar P. interpunctella, and to decrease with the density of infectious cadavers in the case of fifth instars, and the usual assumption was found not to apply in the experimental system. Expand
Cannibalism and coprophagy are modes of transmission of Blastocrithidia triatomae (Trypanosomatidae) between triatomines.
TLDR
B. triatomae was transmitted directly between triatomines by cannibalism and coprophagy, and the efficiency of transmission was not influenced by the blood source--mice or chickens--fed to the infected donor bugs although chicken blood lyses the epimastigotes of the stomach population. Expand
Virus Transmission in Gypsy Moths is not a Simple Mass Action Process
TLDR
A decline in the transmission constant was observed as the densities of both healthy larvae and pathogen increased, indicating that the rate of disease transmission is not directly proportional to the product of these variables. Expand

A series of laboratory infections was carried out to shed light on the life cycle of Sarocystis stehlinii n.sp. Expand
The Population Dynamics of Microparasites and Their Invertebrate Hosts
TLDR
Three simple models embodying the essentials of the dynamical interaction between invertebrate hosts and their directly transmitted microparasites suggest that the baculovirus and microsporidian infections of many temperate forest insects will tend to produce stable cycles in host abundance and in prevalence of infection, with periods in the range 5-12 years.

Cannibalism on Nuclear Polyhedrosis Virus Infected Larvae By Heliothis Armigera (Hubn.) and its Effect on Viral Infection
TLDR
Study on cannibalism by Heliothis armigera (Hubn.) larvae on nuclear polyhidrosis virus (NPV)-infected larvae and feeding on virosed cadavers revealed that cannibalism was significantly higher on NPV-infected (3 days post inoculation) larvae than either healthy larvae or those which had been just inoculated.

Direct transmission of Trypanosoma cruzi between vectors of Chagas' disease.
TLDR
Experiments on coprophagy provided the first conclusive demonstration that transmission of T. cruzi occurs between individual Triatoma infestans, as a result of coprophagic behaviour alone, and excluding the possibility of cannibalistic transmission. Expand
