Population Dynamics of Greenhouse Thrips (Heliothrips haemorrhoidalis) on Avocado Under Single and Combined Predator Releases

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The greenhouse thrips, Heliothrips haemorrhoidalis (Bouché, 1833), is an important avocado pest in New Zealand, where repeated infestations reduce leaf quality and tree vigour. To assess biological control stability under different predator assemblages, this study evaluated thrips population dynamics and predator survival across two sequential phases ...

Insect‐resistant soybean genotypes accumulate rutin and its O‐methylated derivative narcissin, a more potent flavonol targeting Anticarsia gemmatalis digestive and detoxification enzymes and reducing larval survival

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5921-5933, 15 August 2026.
Abstract BACKGROUND Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect‐resistant cultivars have long been associated with the constitutive accumulation of quercetin‐derived flavonols, the biochemical mechanisms underlying this resistance remain poorly ...

A 3D Model of Ryegrass Shoot Architecture, Sward Light Interception and Photosynthesis

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.
Increasing the photosynthetic capacity of perennial ryegrass (Lolium perenne L.) is required to improve the productivity of pastoral farming in temperate regions. A three‐dimensional (3D) model was constructed of the shoot growth of ryegrass based on plant morphological traits such as tiller angle, leaf angle, leaf width, number of tillers per plant ...

Application of a novel molecular diagnostic method to examine the spatio‐temporal trends of Carcelia iliaca, a larval parasitoid of oak processionary moth (Thaumetopoea processionea)

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 3, Page 348-356, August 2026.
The oak processionary moth is an invasive pest in the United Kingdom that threatens biodiversity and public health, with rising control costs highlighting the need for sustainable management alternatives Conservation biocontrol using the parasitoid fly Carcelia iliaca is promising but key biological data gaps hinder evidence‐based policy development.

Spectral response of guava leaves under infestation by Costalimaita ferruginea (coleoptera: Chrysomelidae)

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 3, Page 398-409, August 2026.
Coccinellidae (Coleoptera), Miridae (Hemiptera), Hemerobiidae (Neuroptera), Pentatomidae (Hemiptera), Anystidae (Acari), Erythraeidae (Acari) and spiders (Araneidae, Oxyopidae and Salticidae) fed on the invasive paropsine leaf beetles in Marlborough, New Zealand.

Analysing the Ecological Requirements of the Australian Tortoise Beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) to Determine the Prospects for Its Invasion Process

open access: yesJournal of Applied Entomology, Volume 150, Issue 7, Page 955-967, August 2026.
ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.

Dendroindication of Retrospective Larch Defoliation [PDF]

open access: yes, 2018
We propose a method for dating of growth seasons of Siberian larch (Larix sibirica Ledeb.) following insect infestation events and defoliation. Needle damage during the growth phase triggers tree investment into additional growth of brachyblasts within ...

Adequate management of defoliation post-fire would not affect the metabolic activity of axillary buds on grasses

open access: yes, 2019
Controlled burning is often used to improve plant structure on rangelands adapted to fire. However, possible damage resulting from post-fire grazing to reappearing desirable plant species may be a serious issue hindering usage of this method.

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1143-1160, August 2026.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.
