Commercial Product Based on Metarhizium Anisopliae Affects Survival, Midgut Morphology, and Behavior in the Stingless Bee Scaptotrigona depilis (Hymenoptera: Apidae)

Environmental Toxicology, EarlyView.
ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.

First Record of Female Philopatry in the Tribe Centridini (Hymenoptera: Apidae)

Sociobiology
This study addresses the behavior and ecology of the solitary bee Centris aenea. The objective was to verify the philopatry of this bee’s females. The study was carried out in a nest aggregation in the Restinga area in Coroa Vermelha, Santa Cruz de ...

Exosymbiotic microbes within fermented pollen provisions are as important for the development of solitary bees as the pollen itself

Ecology and Evolution, 2022
Developing bees derive significant benefits from the microbes present within their guts and fermenting pollen provisions. External microbial symbionts (exosymbionts) associated with larval diets may be particularly important for solitary bees that suffer

Foraging energetics reveals late‐summer challenges for pollinators across two British cities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Using the Solitary Pollinator Osmia lignaria to Bridge Agricultural Practice and Ecological Theory

Ecology and Evolution
With global pollinator populations in decline and colony collapse disorder threatening honey bee colony loss, understanding the biology and management of alternative pollinators has become increasingly urgent.

Laboratory acute contact toxicity test with the leafcutter bee Megachile rotundata

Julius-Kühn-Archiv, 2020
So far little is known about the toxicity of Plant Protection Products (PPPs) to solitary bees other than Osmia spp. as well as the inter- and intra-species sensitivity differences of honey bees and solitary bees.

From individuals to networks: The role of variation in plant–pollinator communities' responses to global change

Journal of Animal Ecology, EarlyView.
This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...

Does Decreasing the Generosity of Payments to Single Parents Have Employment and Earnings Effects? Evidence from Australian Administrative Data*

Economic Record, EarlyView.
We examine the impact of two changes to Australia's Parenting Payment Single (PPS) program, a welfare payment for low‐income single mothers. One change lowered the age of the youngest child cut off for program eligibility, forcing new welfare entrants onto the less generous Newstart (unemployment) payment.

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.

Enhancing Alfalfa (Medicago sativa) Seed Yield: The Effect of Honey Bee (Apis mellifera) Supplementation and Efficiency of Other Pollinators

Biology
Alfalfa (Medicago sativa) is an important fodder crop with 16–25% protein and 20–30% fibre content. It requires pollinators for seed development through a process known as “tripping”. Honey bees are preferred for their easy management and mass rearing to
