Coexistence of three specialist aphids on common milkweed, Asclepias syriaca.
Coexistence of host-specific herbivores on plants is believed to be governed by interspecific interactions, but few empirical studies have systematically unraveled these dynamics. We investigated the role of several factors in promoting coexistence among the aphids Aphis nerii, Aphis asclepiadis, and Myzocallis asclepiadis that all specialize on common milkweed (Asclepias syriaca). Competitive ...
متن کاملSpecificity of induced plant responses to specialist herbivores of the common milkweed Asclepias syriaca
Induced plant responses to herbivory appear to be universal, yet the degree to which they are specific to sets of herbivores is poorly understood. The generalist/specialist hypothesis predicts that generalist herbivores are more often negatively affected by host plant defenses, wheras specialists may be either unaffected by or attracted to these same ‘‘plant defenses’’. Therefore, specialists s...

15 صفحه اولNatural selection on common milkweed (Asclepias syriaca) by a community of specialized insect herbivores
Hypothesis: Genetic variation in plant defence structures a community of herbivores and ultimately mediates co-evolution. Organisms: Common milkweed (Asclepias syriaca) and five natural insect herbivores (seed bug, leaf mining fly, monarch caterpillar and two beetles). Methods: Quantitative genetic field experiment over 2 years, genetic selection analyses, and measurement of five defensive trai...
متن کاملAsymmetry of plant-mediated interactions between specialist aphids and caterpillars on two milkweeds
1. Plant-mediated interactions between co-occurring herbivores play an important role in insect herbivore communities. Although induced resistance pathways associated with jasmonic acid and salicylic acid are often implicated in such plant-mediated interactions, there are few examples from non-model systems involving specialized herbivores that regularly interact in nature. 2. Here, we tested r...
