Biochar Improves Plant Vigor and Defense Response to Green Peach Aphid Myzus persicae in Hydroponic Lettuce (Lactuca sativa)

open access: yesFood and Energy Security, Volume 15, Issue 5, September/October 2026.
ABSTRACT Biochar (BC) is increasingly recognized as a sustainable agricultural amendment to improve soil health, promote plant growth, and suppress insect pests. While its application has been extensively refined in conventional soil‐based agroecosystems, its performance in hydroponics, particularly in liquid formulations remain largely unexplored. The

Spatial Representation of Feeding and Oviposition Odors in the Brain of a Hawkmoth

open access: yesCell Reports, 2018
Summary: Female hawkmoths, Manduca sexta, use olfactory cues to locate nectar sources and oviposition sites. We investigated if the behavioral significance of odorants is represented already in the antennal lobe, the first olfactory neuropil of the ...

The Potential for Pest Management Using Plant‐Derived Signaling Compounds

open access: yesEcological Research, Volume 41, Issue 5, September 2026.
Plant‐derived signaling compounds mediate ecological interactions among plants, herbivores, their natural enemies, and neighboring plants. This graphical summary highlights three approaches to leveraging such ecological interactions for environmentally benign pest management: (1) Recruitment of natural enemies: Using herbivory‐induced plant volatiles ...

Storage hexamer utilization in Manduca sexta

open access: yesJournal of Insect Science, 2003
In preparing for metamorphosis insects store in their hemolymph and fat bodies a major nutrient reserve of 500-kDa hexamerins. At least three hexamerins serve this function in Lepidoptera, including arylphorin (ArH) and two high methionine proteins (M ...

The potassium impermeable apical membrane of insect epithelia: a target for development of safe pesticides

open access: yesMemorias do Instituto Oswaldo Cruz, 1987
Columnar cell apical membranes (CCAM) in series with goblet cell apical membranes (GCAM) form an electroosmotic barrier separating the midgut lumen from epithelial cell cytoplasm.

Mycorrhiza‐induced resistance against Botrytis cinerea in tomato operates through the systemin signalling cascade

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3522-3539, September 2026.
Prosystemin expression in mycorrhizal plants and comparative analysis of prosystemin and mycorrhiza in induced resistance. Summary Arbuscular mycorrhizal fungi enhance plant resistance against necrotrophic fungi by priming jasmonic acid‐dependent defences.

No Evidence for Ionotropic Pheromone Transduction in the Hawkmoth Manduca sexta. [PDF]

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 ...

Silverleaf Nightshade (Solanum elaeagnifolium) Undergoes Guild‐Specific Transcriptomic Reprogramming Against Chewing Versus Piercing Sucking Herbivory

open access: yesPhysiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Solanum elaeagnifolium (silverleaf nightshade, SLN) is a globally invasive perennial weed with reproductive plasticity and complex defence systems that significantly impact crop yields by invading fields of staple, commercial and ornamental crops.

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis

open access: yesAdvanced Science, Volume 13, Issue 46, 17 August 2026.
In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...

A quantitative study of adipokinetic hormone of the firebug, Pyrrhocoris apterus [PDF]

open access: yes, 2002
The development of an enzyme-linked immunoassay (ELISA) for the adipokinetic neuropeptide hormone, Pya-AKH, from the firebug Pyrrhocoris apterus L. is described. The ELISA measures as little as 20 fmol of Pya-AKH.
