THE EFFECT OF PENTAKEEP®-V APPLICATION ON FLOWER TRAITS AND NECTAR PRODUCTION IN Hosta TRATT. ‘KROSSA REGAL’

Acta Scientiarum Polonorum: Hortorum Cultus, 2016
In modern horticulture the use of biostimulators for obtaining the maximum yields and qualities of the crops is favoured. Pentakeep®-V, the fertilizer containing 5-aminolevulinic acid (ALA) is currently recommended.

Extrafloral Nectar of Bottle Gourd: Synthesis and Role of Carbohydrates as a Dietary Supplement for Nesidiocoris tenuis Reuter (Heteroptera: Miridae)

Agriculture
Plants can provide natural enemies with alternative food resources that enhance their performance in addition to prey consumption. Extrafloral nectaries attract beneficial insects by supplying nectar in exchange for pest suppression, although other ...

Floral Phenology, Nectar Secretion Dynamics, and Honey Production Potential, of Two Lavender Species (Lavandula Dentata, and L. Pubescens ) in Southwestern Saudi Arabia

Journal of Apicultural Science, 2015
The aim of the current study was to determine the floral phenology, nectar secretion dynamics, and honey production potentials of two naturally growing lavender species (L. dentata and L. pubescens), in southwestern Saudi Arabia.

Optimising daily sampling of plant–bee interaction networks

Journal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

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.

Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in Desfontainia fulgens

Ecology and Evolution
Nectar robbery is common in hummingbird‐pollinated plants and is often assumed to reduce plant reproductive success by depleting floral rewards and disrupting pollination.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

Insect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Characterization of the dynamic microbiome evolution across thrips species

Insect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Extreme events induced by climate change alter nectar offer to pollinators in cross pollination-dependent crops

Scientific Reports
Both severe reductions and increases in rainfall can stress plants and modify floral traits involved in plant-pollinator interactions, such as nectar production.

Variation in Nectar Volume and Sugar Concentration of Allium ursinum L. ssp. ucrainicum in Three Habitats

The Scientific World Journal, 2012
Floral nectar volume and concentration of ramson (Allium ursinum L. ssp. ucrainicum) were investigated in three different habitats, including two types of sessile oak-hornbeam association on brown forest soil with clay illuviation and a silver lime ...
