A direct contact pig influenza challenge model for assessing protective efficacy of monoclonal antibodies

open access: yesFrontiers in Immunology, 2023
Monoclonal antibodies (mAbs) can be used to complement immunization for the therapy of influenza virus infection. We have established the pig, a natural large animal host for influenza A, with many physiological, immunological, and anatomical ...

Predation success by a plant-ant indirectly favours the growth and fitness of its host myrmecophyte [PDF]

open access: yes, 2013
Mutualisms, or interactions between species that lead to net fitness benefits for each species involved, are stable and ubiquitous in nature mostly due to "byproduct benefits" stemming from the intrinsic traits of one partner that generate an indirect ...

Host plant and population source drive diversity of microbial gut communities in two polyphagous insects

open access: yesScientific Reports, 2019
Symbioses between insects and microbes are ubiquitous, but vary greatly in terms of function, transmission mechanism, and location in the insect. Lepidoptera (butterflies and moths) are one of the largest and most economically important insect orders ...

The Irish potato famine pathogen Phytophthora infestans translocates the CRN8 kinase into host plant cells [PDF]

open access: yes, 2012
Phytopathogenic oomycetes, such as Phytophthora infestans, secrete an arsenal of effector proteins that modulate plant innate immunity to enable infection. We describe CRN8, a host-translocated effector of P. infestans that has kinase activity in planta.

Plant sulphur nutrition influencing host-plant selection and performance of insect herbivores [PDF]

open access: yes, 2003
In the past several years, sulphur (S) deficiencies in agricultural crops have been reported with increasing frequency and therefore more interest has been directed into plant nutrition and fertilisation with particular respect to this element.

Impact of Host Plant Species and Whitefly Species on Feeding Behavior of Bemisia tabaci

open access: yesFrontiers in Plant Science, 2019
Whiteflies of the Bemisia tabaci species complex are economically important pests of cassava. In Africa, they cause greatest damage through vectoring viruses responsible for cassava mosaic disease and cassava brown streak disease. Several cryptic species

Host choice and host leaving in Rhopalosiphum padi (Hemiptera: Aphididae) emigrants and repellency of aphid colonies on the winter host [PDF]

open access: yes, 2000
Host choice and winter-host leaving in emigrants of bird cherry–oat aphid, Rhopalosiphum padi (Linnaeus), were investigated in the laboratory. In settling choice tests, emigrants collected from the winter host, Prunus padus, preferred this plant over ...

A Histological Study of Aspergillus flavus Colonization of Wound Inoculated Maize Kernels of Resistant and Susceptible Maize Hybrids in the Field

open access: yesFrontiers in Microbiology, 2018
Aspergillus flavus colonization in developing kernels of maize single-cross hybrids resistant (Mp313E × Mp717) and susceptible (GA209 × T173) to aflatoxin accumulation was determined in the field over three growing seasons (2012–2014).

Two genomes of highly polyphagous lepidopteran pests (Spodoptera frugiperda, Noctuidae) with different host-plant ranges

open access: yesScientific Reports, 2017
Emergence of polyphagous herbivorous insects entails significant adaptation to recognize, detoxify and digest a variety of host-plants. Despite of its biological and practical importance - since insects eat 20% of crops - no exhaustive analysis of gene ...

Parasitoid load affects plant fitness in a tritrophic system [PDF]

open access: yes, 2008
Plants attacked by herbivorous insects emit volatile compounds that attract predators or parasitoids of the herbivores. Plant fitness increases when these herbivorous insects are parasitized by solitary parasitoids, but whether gregarious koinobiont ...
