Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

open access: yesAgricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Codes and supplemental data for 'Phloem evolution in ferns was shaped by phylogeny and records a trend of decreasing conductivity through geological time'

open access: yes
The phloem, the sugar-transporting tissue in vascular plants, is one of the most important but least well characterised plant tissues from an evolutionary perspective.

Monitoring spirodiclofen resistance in female Brevipalpus yothersi (Acari: Tenuipalpidae) from citrus orchards in Southeastern Brazil

open access: yesAgricultural and Forest Entomology, EarlyView.
Spirodiclofen resistance levels in B. yothersi varied geographically across the Brazilian citrus belt, with higher resistance in the central region. Sublethal effects included reduced oviposition, increased non‐viable eggs and disrupted female reproduction.

Redistribution of Nickel, Cobalt, Manganese, Zinc, and Cadmium via the Phloem in Young and Maturing Wheat

open access: yes, 2005
The phloem mobility of heavy metals is relevant to the redistribution of micronutrients and pollutants and, ultimately, to the quality of harvested plant parts. The relative mobility in wheat may vary considerably between different cations.

Development and survival of Bemisia tabaci MEAM1 (Hemiptera: Aleyrodidae) on Eucalyptus genotypes

open access: yesAgricultural and Forest Entomology, EarlyView.
This study provides the first experimental evidence of the biological performance of Bemisia tabaci MEAM1 on Eucalyptus genotypes. Development time was shortest and viability highest on soybean compared with the evaluated Eucalyptus genotypes. B. tabaci MEAM1 completed its development on Eucalyptus camaldulensis and Eucalyptus urophylla × Eucalyptus ...

Temperature interacts with jack pine host defences to influence the growth of mountain pine beetle‐associated fungi

open access: yesAgricultural and Forest Entomology, EarlyView.
Optimal growing temperatures varied with mountain pine beetle‐associated fungal species. There was only a marginal impact of temperature on the response of fungi to defensive monoterpenes of novel host pine. Interspecific facilitation occurred for Leptiographuim longiclavatum when grown in Ophiostoma montium‐induced treatments at optimal temperatures ...

Evidence for positive population‐level responses but not individual performance of sycamore aphids under elevated CO2

open access: yesAgricultural and Forest Entomology, EarlyView.
The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Three‐Dimensional Architecture of Ectopic Epithelium and Vasculature in Ovarian Endometriosis Revealed by Tissue‐Clearing Imaging

open access: yesCell Proliferation, EarlyView.
Our study employed a modified tissue‐clearing method combined with deep imaging for 3D reconstruction of ovarian endometriosis (OEM) lesions, revealing its morphological polymorphism at tissue and cellular levels. Besides, vessels preferentially clustered around the ectopic epithelium, with their distribution pattern strongly linked to the location of ...

Plant Traits and Reproduction in a Multitrophic System: The Role of Aphids, Parasitoids and Hyperparasitoids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
