Defoliation Frequency and Intensity of Arrhenathherum elatius [PDF]

This experiment was conducted with the aim of studying whether the frequency and intensity of defoliation of the temperate grass fromental (Arrhenatherum elatius (L.) Presl.) affected its total dry matter (DM)/ha yield as well as the seasonal ...

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.

Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle

Integrative Zoology, EarlyView.
Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.

Light interception, chemical, and productive characteristics of elephant grass subjected to different cutting intervals

Semina: Ciências Agrárias, 2019
This study aimed to evaluate the interception of light (%IL), leaf area index (LAI), and the chemical and productive characteristics of elephant grass (Pennisetum purpureum Schum) under different defoliation frequencies (30, 45, 60, 75, and 90 days after

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

Status of ash (Fraxinus spp.) in mixed hardwood post‐outbreak forests near the epicentre of the emerald ash borer invasion

Agricultural and Forest Entomology, EarlyView.
The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

Biomass allocation, compensatory growth and internal C/N balance of Lolium perenne in response to defoliation and light treatments

, 2016
Light environments can have a considerable influence on how plants respond to defoliation through influencing the biomass allocation patterns and internal C/N ratio.

Características morfogênicas e estruturais e produção de forragem do capim-marandu submetido a intensidades e freqüências de desfolhação Morphogenetic and structural traits and herbage production of marandugrass under intensities and frequencies of defoliation

Revista Brasileira de Zootecnia, 2006
Este trabalho foi realizado com o objetivo de avaliar a influência de intensidades (10 e 20 cm) e freqüências de desfolhação (três intervalos de cortes, definidos pelo aparecimento de 5, 7 e 9 folhas/perfilho após cada evento de desfolhação) nas ...

Responses of bahiagrass to nitrogen and defoliation

, 2003
Pensacola bahiagrass (Paspalum notatum Flgge) swards pretreated with fertilizer nitrogen rates of 0 and 66-99 kg N ha-1 year-1 were exposed to repeated, severe defoliation (i.e., removal of all laminae) of every day (D1), every 2 days (D2), and every 4 ...

Exploiting Native Biodiversity for Invasive Species Management: The Case of Exorista larvarum as a Natural Enemy of the Invasive Box Tree Moth Cydalima perspectalis

Entomologia Experimentalis et Applicata, EarlyView.
The investigations evaluated the performance of the native parasitoid Exorista larvarum (L.) on last instar Cydalima perspectalis (Walker) larvae, using the factitious host Galleria mellonella (L.) as a control. Laboratory bioassays were conducted using no‐choice and choice (1:1 and 5:5) experimental designs.
