Ensemble Modeling Reveals Threats to Pollination Services From Asynchronous Range Shifts Between Camellia oleifera and Its Specialized Wild Bee Pollinators [PDF]

open access: yesEcology and Evolution
Camellia oleifera is a self‐incompatible woody oil crop endemic to China that relies solely on insect pollination for seed production. Its flowering period, from late October to late December, coincides with seasonally low temperatures that suppress ...

Flower pollination algorithm with pollinator attraction [PDF]

open access: yesEvolutionary Intelligence, 2022
The Flower Pollination Algorithm (FPA) is a highly efficient optimization algorithm that is inspired by the evolution process of flowering plants. In the present study, a modified version of FPA is proposed accounting for an additional feature of flower pollination in nature that is the so-called pollinator attraction.

Adventive Gryon aetherium Talamas (Hymenoptera, Scelionidae) associated with eggs of Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae) in the USA [PDF]

open access: yesJournal of Hymenoptera Research, 2021
Bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae), has become a major pest of cole crops (cabbage, broccoli, cauliflower, kale) in California since its arrival in 2008. In this study we documented parasitism of B.

Ethnoecology of pollination and pollinators [PDF]

open access: yesRevue d'ethnoécologie, 2015
This paper brings together three case studies on the interrelationships amongst people, pollination processes and pollinators (notably honeybees). In the palm groves of Saharan oases, the milieu and varieties of palm trees are created by horticulturalists, who fulfil themselves the role of pollinators.

Factors Affecting Progeny Production and Sex Ratio of Gryon aetherium (Hymenoptera: Scelionidae), a Candidate Biological Control Agent for Bagrada hilaris (Hemiptera: Pentatomidae)

open access: yesInsects, 2022
Manipulating the factors that influence progeny production and sex ratio in parasitoids can help maximize the production of quarantine bioassays and/or mass releases.

New records of pollinators and other insects associated with Arizona milkweed, Asclepias angustifolia, at four sites in Southeastern Arizona

open access: yesJournal of Pollination Ecology, 2021
Asclepias angustifolia is a Mexican milkweed that barely enters the U.S.A. Its pollinators and other insect visitors have not been investigated. During 2018 and 2019, insect visitors were photographed at a native population and three gardens in and near ...

Flowers through insect eyes: the contribution of pollinator vision to the evolution of flower colour [PDF]

open access: yes, 2010
PhDFlowers’ colours are an essential element of their ability to attract visits from pollinators. However, the colours as they appear to human observers can differ substantially from their appearance to insect pollinators, and so it is essential to ...
