Host plant or geographic barrier? Reproductive compatibility among Diatraea saccharalis populations from different host plant species and locations in Argentina
(Blackwell Publishing, 2019-02)
The sugarcane borer, Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae), is one of the main lepidopteran pests of sugarcane and maize. The association of insects with different environments and/or host plants may ...
Innate Host Habitat Preference in the Parasitoid Diachasmimorpha longicaudata: Functional Significance and Modifications through Learning
(2016)
Parasitoids searching for polyphagous herbivores can find their hosts in a variety of habitats.
Under this scenario, chemical cues from the host habitat (not related to the host) represent
poor indicators of host location. ...
Host-specific gene expression as a tool for introduction success in Naupactus parthenogenetic weevils
(Public Library of Science, 2021-07-30)
Food resource access can mediate establishment success in invasive species, and generalist herbivorous insects are thought to rely on mechanisms of transcriptional plasticity to respond to dietary variation. While asexually ...
Host Plant Adaptation in Cactophilic Species of the Drosophila buzzatii Cluster: Fitness and Transcriptomics
(Oxford Univ Press Inc, 2018-08)
Host plant shifts in herbivorous insects often involve facing new environments that may speed up the evolution of oviposition behavior, performance-related traits, morphology, and, incidentally, reproductive isolation. In ...
Modulation of host plant immunity by Tobamovirus proteins
(2017-03)
To establish successful infection, plant viruses produce profound alterations of host physiology, disturbing unrelated endogenous processes and contributing to the development of disease. In tobamoviruses, emerging evidence ...
Olfactory attraction of the larval parasitoid, Hyposoter horticola, to plants infested with eggs of the host butterfly, Melitaea cinxia
(Entomological Society of America, 2010-01)
Parasitoids locate inconspicuous hosts in a heterogeneous habitat using plant volatiles, some of which are induced by the hosts. Hyposoter horticola Gravenhost (Hymenoptera: Ichneumonidae) is a parasitoid of the Glanville ...
Host selection, oviposition behaviour and leaf traits in a specialist willow sawfly on species of Salix (Salicaceae)
(Wiley, 2013-12)
Plant genotype influences plant–herbivore interactions by affecting insect attraction, acceptance and development. Here we linked oviposition behaviour of the specialist willow sawfly Nematus oligospilus Förster (Hymenoptera: ...
Insect herbivory in climber-host shrubs associations: Benefit or detriment?
(Wiley Blackwell Publishing, Inc, 2011-11)
Spatial proximity between different plant species could modify the sign (positive or negative) of plant-herbivore interaction. The chance of a plant being detected and colonized by herbivorous insects depends not only on ...
Host plant stimuli effects on survival and duration of dormancy of Rhagoletis zoqui, Rhagoletis completa (Diptera: Tephritidae) and associated parasitoids
(Cambridge University Press, 2022-06)
Tephritid fruit flies in the genus Rhagoletis bridge between predictable periods of fruit availability by becoming dormant. To cope with acyclic unpredictable events (e.g., frost, mast seeding, etc), a proportion of the ...
Alfalfa mosaic virus (AMV): Genetic diversity and a new natural host
(Edizioni Ets, 2021-10)
Alfalfa mosaic virus (AMV) is a plant virus belonging to the genus Alfamovirus in the family Bromoviridae. AMV occurs worldwide and is one of the most important viruses affecting a large number of plant species, mainly ...
