Root Weevil Feeding on Rhododendron: A Review [PDF]

open access: yesJournal of Environmental Horticulture, 1983
Specific chemical compounds present in Rhododendron leaves stimulate adult root weevil feeding. The resistance of certain Rhododendron species to weevil feeding is due to the presence of volatile terpene constituents of the leaves.

Effects of elevated temperature and CO2 on aboveground-belowground systems: a case study with plants, their mutualistic bacteria and root / shoot herbivores

open access: yesFrontiers in Plant Science, 2013
Interactions between above- and belowground herbivores have been prominent in the field of aboveground-belowground ecology from the outset, although little is known about how climate change affects these organisms when they share the same plant ...

Comparing Exogenous Methods to Induce Plant-Resistance Against a Bark-Feeding Insect

open access: yesFrontiers in Plant Science, 2021
Exogenous application of the plant hormone methyl jasmonate (MeJA) can trigger induced plant defenses against herbivores, and has been shown to provide protection against insect herbivory in conifer seedlings.

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Digestive enzymes of vine weevil (Otiorhynchus sulcatus) as potential targets for insect control strategies. [PDF]

open access: yes, 2002
Over the previous quarter century the vine weevil (Otiorhynchus sulcatus) has become a pest of horticultural and agricultural plants. The vine weevil is a polyphagous coleopteran insect and is able to attack over one hundred different plant species.

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

open access: yesOikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...

Intraspecific Variation in Plant Defense Alters Effects of Root Herbivores on Leaf Chemistry and Aboveground Herbivore Damage [PDF]

open access: yes, 2008
Root herbivores can indirectly affect aboveground herbivores by altering the food quality of the plant. However, it is largely unknown whether plant genotypes differ in their response to root herbivores, leading to variable defensive phenotypes.
