| diversity and abundance of phyllosphere bacteria are linked to insect herbivory. | simultaneous or sequential attack by herbivores and microbes is common in plants. many seed plants exhibit a defence trade-off against chewing herbivorous insects and leaf-colonizing ('phyllosphere') bacteria, which arises from cross-talk between the phytohormones jasmonic acid (ja, induced by many herbivores) and salicylic acid (sa, induced by many bacteria). this cross-talk may promote reciprocal susceptibility in plants between phyllosphere bacteria and insect herbivores. in a population of n ... | 2014 | 24383417 |
| aversion and attraction to harmful plant secondary compounds jointly shape the foraging ecology of a specialist herbivore. | most herbivorous insect species are restricted to a narrow taxonomic range of host plant species. herbivore species that feed on mustard plants and their relatives in the brassicales have evolved highly efficient detoxification mechanisms that actually prevent toxic mustard oils from forming in the bodies of the animals. however, these mechanisms likely were not present during the initial stages of specialization on mustard plants ~100 million years ago. the herbivorous fly scaptomyza nigrita (d ... | 2016 | 27096082 |
| herbivory by leaf miners in response to experimental shading of a native crucifer. | we tested the hypothesis that light intensity was the direct, proximal mechanism causing significantly higher vulnerability of bittercress (cardamine cordifolia a. gray) clones in the sun to herbivory by a leaf-mining fly (scaptomyza nigrita wheeler). clones in the sun were experimentally shaded. plant performance and losses to leaf miners were compared to controls in the sun and natural willow shade. leaf-mining damage was significantly higher on artificially-shaded plants (p<0.01), opposite of ... | 1988 | 28312431 |
