Helicopter drops in an open economy when markets are incomplete

open access: yesEconomic Inquiry, EarlyView.
Abstract We characterize the spillover effects of helicopter drops and optimal monetary policy in a tractable two‐country overlapping generations model with incomplete markets. As helicopter drops can affect the distribution of income across countries, they create room for redistribution policies which are particularly relevant when agents are ...

Attractiveness of Melon Genotypes to Whitefly (Bemisia tabaci) Mediated by Foliar Morphological and Biochemical Traits

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study identifies melon genotypes resistant to Bemisia tabaci by integrating morphological and biochemical leaf traits. Using free‐choice and no‐choice assays, we demonstrate that resistance is primarily mediated by antixenosis. Genotypes CNPH 11‐1071‐43, CNPH 06‐1047‐343, CNPH 13‐1076, and BG MEL 16 significantly reduced whitefly settling and ...

Methyl Jasmonate and Methyl Salicylate Differentially Modulate Direct and Indirect Defenses in Coffee Plants Against the White Mealybug

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

open access: yesEcological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Canopy position and tree size structure the distribution of honeydew‐producing scale insects (Hemiptera: Coccoidea) in a temperate hardwood forest

open access: yesEcological Entomology, EarlyView.
Scale insect abundance peaked in the upper canopy of sugar maples. Parthenolecanium peaked on older internodes; Lepidosaphes on the current leader. Internodes longer than the previous carried more scales; wider ones fewer. Abstract Forest canopies are vertically stratified habitats in which microclimate and host tissue quality vary with height.

Anxiety during the transition to parenthood: Partners' cognitive and emotional experience

open access: yesFamily Relations, EarlyView.
Abstract Objective This qualitative study aimed to describe mothers and fathers' cognitive and emotional responses to their coparent's anxiety during the transition to parenthood. Background The transition to parenthood is associated with increased anxiety in parents and heightened interdependence of partners.
