AY-‐WB phytoplasma manipulations of host and non-‐host leafhopper interactions
Hempitera. In plant hosts, phytoplasmas induce physiological changes and in both hosts modulate plant-‐insect interactions. Previously, interactions have been examined with both hosts infected with phytoplasmas. Thus, it is unclear which organism the effect stems from or how phytoplasmas …

Influence of feeding-location on nutritional quality for cochineal insects (Homoptera : Dactylopiidae) on Opuntia ficus-indica (Cactaceae)
The cochineal insect Dactylopius opuntiae has been an extremely successful biocontrol agent of the cactus weed Opuntia ficus-indica. Its resounding success has allowed us to take a closer look at how the relationships between biocontrol agents and their host plants are maintained. The prickly pear, …

The dynamics of molecular components that regulate aphid-plant interactions
Aphids are economically important insect pests, which feed on phloem sap using stylets. Aphids cause significant losses of crop yield, through draining plant resources and vectoring over 275 plant viruses. In plant-pathogen interactions, basal plant defense involving pathogen associated molecular …

Parallel and Nonparallel Patterns of Genetic Co-Differentiation: Evidence for Host Associated Differentiation Among Trophic Levels of the Oak Gall Wasp System
Populations of phytophagous insects whose life cycles are intimately related to their host plants can express host-associated differentiation (HAD) in the form of genetic divergence and/or RI isolation across alternative host plants. In this work, we ask if HAD cascades to higher trophic levels in …

Wood trait preferences of Neotropical xylophagous beetles (Coleoptera: Cerambycidae)
… strategies are correlated with functional plant traits, such as wood density (WD), moisture content (MC), bark thickness (BT), and nitrogen content (N); these traits affect the nutrients available to xylophagous insects. Cerambycid beetles feed on substrates that vary in these traits, but …
