Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Ecophysiological aspects of nectar reabsorption
A number of approaches, both direct and indirect, have shown that nectar is reabsorbed by numerous plant species, irrespective of the age or sex of the flower.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success
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.

Towards elucidating the differential regulation of floral and extrafloral nectar secretion [PDF]
Nectar is a rich source of sugars that serves the attraction of pollinators (floral nectar) or predatory arthropods (extrafloral nectar). We just begin to understand the similarities and differences that underlie the secretory control of these two important types of plant secretions.

Ants contribute to raspberry pollination in protected cropping systems
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

Flowering, nectar secretion, and structure of the nectary in the flowers of Acer pseudoplatanus L.
Flowering and nectar release in Acer pseudoplatanus were investigated between 2011 and 2013. The micromorphology of the floral and nectary elements was observed using a scanning electron microscope and the anatomy of nectaries was examined by light ...

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Nectar secretion and pollen production in Hyacinthus orientalis ‘Sky Jacket’ (Asparagaceae)
Flowering, nectar secretion, and pollen production in Hyacinthus orientalis ‘Sky Jacket’ (Asparagaceae) were studied between 2013 and 2015 in Lublin, SE Poland (51°16' N, 22°30' E). The flowering was weather-dependent.

Squash Silverleaf Disorder (SLD) is growing in its economic impact due to the invasive behaviour of the silverleaf whitefly (Bemisia tabaci MEAM1). In this review we summarize what is currently known about the whitefly‐squash interaction, how both the disease and the whitefly are being affected by climate change, and discuss current and novel ...
