Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7558-7574, October 2026.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

A new acyclic diterpene glycoside from Nicotiana attenuata with a mild deterrent effect on feeding Manduca sexta larvae

open access: yes, 2006
To investigate the role of secondary metabolites in the feeding behavior of Manduca sexta larvae feeding on Nicotiana attenuata, an aqueous acetone extract of the aerial parts of the plant was subjected to feeding-performance bioassay-guided ...

Disparity in the distribution of suitable habitat as a metric for capturing responses to contrasting land‐use types

open access: yesEcological Applications, Volume 36, Issue 6, September 2026.
Abstract Global species observations from community science platforms offer an unprecedented opportunity to analyze large‐scale patterns of biodiversity. This holds great promise for developing data‐driven metrics to measure species' responses to landscape‐level environmental changes, essential for ameliorating the ongoing biodiversity crisis.

The role of low levels of juvenile hormone Esterase in the metamorphosis of Manduca sexta

open access: yesJournal of Insect Science, 2001
The activity of juvenile hormone esterase (JHE) in feeding fifth instar larvae of Manduca sexta increases gradually with larval weight and rises to a peak after larvae pass the critical weight when juvenile hormone secretion ceases.

Different Effects of Induced Plant Defense on Population Densities of Specialist and Generalist Insects: An Explanation by Mathematical Modeling

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Induced defense chemicals in plants determine the community structure of different insect (herbivore) groups. In particular, specialists are endemic and generalists are non‐endemic in the wild because of the ecological roles of induced secondary metabolites.

No Evidence for Ionotropic Pheromone Transduction in the Hawkmoth Manduca sexta

open access: yesPLOS ONE, 2016
Insect odorant receptors (ORs) are 7-transmembrane receptors with inverse membrane topology. They associate with the conserved ion channel Orco. As chaperon, Orco maintains ORs in cilia and, as pacemaker channel, Orco controls spontaneous activity in olfactory receptor neurons.

α-Cyclodextrin extracts diacylglycerol from insect high density lipoproteins

open access: yesJournal of Lipid Research, 2000
α-Cyclodextrins are water-soluble cyclic hexamers of glucose units with hydrophobic cavities capable of solubilizing lipophiles. Incubating α-cyclodextrin with high density lipophorin from Manduca sexta or Bombyx mori resulted in a cloudy, turbid ...
