Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

Insect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Determinação da área foliar de macadâmia a partir de dimensões lineares do limbo foliar

Agro@mbiente On-line, 2016
A mensuração da área foliar é requerida em vários estudos agronômicos por ser uma das principais medidas para avaliar o crescimento das plantas. Nesse sentido, objetivou-se com o presente trabalho determinar os modelos estatísticos que melhor descrevem a

Neonicotinoid seed treatments do not consistently reduce insect feeding damage nor increase yields in Maryland soy

Agricultural and Forest Entomology, EarlyView.
We compared soybean plants from untreated and treated seeds across 4 sites and 3 years in Maryland. Neonicotinoid seed treatments (NST) provided little reduction in insect stippling damage and no reduction in chewing damage. NST did not result in increased plant biomass or bean yield. Abstract The use of neonicotinoid insecticides in seed treatments in

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

Agricultural 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 ...

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

Entomologia 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 ...

Fungicide Non‐Target Effects Cause Reduced Sawfly Herbivory in Treated and Neighbouring Strawberry Plants

Entomologia Experimentalis et Applicata, EarlyView.
Application of the fungicide Switch 62.5 WG in garden strawberry (Fragaria × ananassa), targeting Botrytis cinerea, reduced sawfly (Cladius spp.) herbivory by up to 94% and improved fruit quality. This non‐target effect also spilled over to neighbouring untreated plants, lowering damage by 46%.

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

Entomologia 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 ...

Does the munch affect the bunch? Using community science to explore insect herbivory and fruit production in an understory plant

Ecological Entomology, EarlyView.
We used iNaturalist records, a longitudinal field survey, and a simulated herbivory experiment to explore how insect herbivory factors are associated with Cornus canadensis fruit production. Naturally observed internal and external insect herbivory was mostly low intensity and did not have a strong relationship with fruit production.
