Orchard Management Influences Predation of Halyomorpha halys Eggs

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We investigated predation of eggs of the invasive stink bug Halyomorpha halys on apple trees in conventional, organic, and extensively managed Dutch orchards. Predation exceeded 40% in extensively managed orchards but was only about 10% in conventional and organic ones. We used camera traps to reveal natural enemies that may contribute to H.

Performance of Fall Armyworm Spodoptera frugiperda Reared on Various Horticultural Crops

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The developmental performance and reproductive success of the Australian population of fall armyworm (Spodoptera frugiperda) were evaluated on five horticultural crops under laboratory conditions. Sweetcorn and bean supported rapid development, lower mortality, and higher fecundity (good performance); whereas capsicum, strawberry, and okra resulted in ...

Chrysoperla externa (Neuroptera: Chrysopidae) as a Potential Biological Control Agent of Raoiella indica (Acari: Tenuipalpidae)

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
First and third instar Chrysoperla externa showed efficient predatory capacity at low R. indica density, but second instar C. externa exhibits a density‐dependent predatory ability. The lacewing C. externa shows promise as a biocontrol agent for R. indica in coconut because it consumed 8362 R. indica females across all its larval instars.

Nutrient addition, but not vertebrate predator exclusion, shapes arthropod communities and herbivory in a temperate forest

open access: yesEcological Entomology, EarlyView.
We experimentally manipulated top‐down (predator exclusion) and bottom‐up (fertilisation) forces in a temperate forest understory to test effects on arthropod densities, body sizes and herbivory. Predator exclusion had no detectable effect on arthropod density, herbivory damage or body size, whereas fertilisation increased herbivory damage and ...

From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

open access: yesEcological Entomology, EarlyView.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

Mergers and Acquisitions as Navigators of Climate Policy Shocks: Evidence from the NOx Budget Trading Program

open access: yesFinancial Management, EarlyView.
ABSTRACT We examine how mergers and acquisitions (M&As) enable firms to adapt to climate policy shocks. Exploiting the adoption of the Nitrogen Oxides (NOx) Budget Trading Program (NBP) across US states as an exogenous shock, we find that firms with NOx‐emitting plants subject to the NBP are more likely to engage in M&As, particularly through vertical ...

Toward a global repository of insect traits (GRIT)

open access: yesInsect Conservation and Diversity, EarlyView.
Biodiversity loss is accelerating, yet insect conservation is hindered by the absence of a centralised, comprehensive trait database. We propose the GRIT, a FAIR, open‐access platform uniting datasets and collaborators worldwide. GRIT will harness advanced computational tools for trait acquisition and imputation, enabling large‐scale ecological ...
