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 ...

Effects of Defoliation at Different Fertility Stages on Material Accumulation, Physiological Indices and Yield of Cotton

open access: yesAgriculture
In recent years, severe hailstorms have caused damage to cotton leaves and stalks. In order to identify the effects of cotton leaf damage on its dry matter accumulation, protective enzyme activity and yield in different periods, in this experiment ...

Defoliation reconsidered?

open access: yes, 2015
Since the 1980s defoliation (often assessed by means of crown transparency) is the most used indicator of tree condition adopted in Europe. It has been criticized for its subjectivity and scarce relation with meaningful endpoints. Here we collated the results of three different studies carried out in France and Italy to investigate the relationship ...

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.

Ecosystem Services Against Illegal Immigration: The Natural Control of the Migratory Butterfly Painted Lady (Vanessa cardui) by Cotesia vestalis (Hymenoptera, Braconidae) on Organic Soybean in Ukraine

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 922-932, August 2026.
In central Ukraine, the migratory butterfly Vanessa cardui emerged as a key pest of organic soybean during its outbreaks in 2019 and 2022. Despite early defoliation, crops recovered strongly due to high parasitism by Cotesia vestalis, reaching 100% in some fields.

Temporal Dynamics of Sporulation of Lecanosticta acicola in Detached Pinus taeda Needles

open access: yesForest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT The timber industry in the southeastern United States relies heavily on Pinus taeda. Over the past decade, impacts from Lecanosticta acicola causing Brown Spot Needle Blight have been increasing on P. taeda. Disease spread is well documented for living needles, with conidia spreading locally and ascospores spreading long distances.
