1172. Dendrobium chryseum Rolfe

open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Dendrobium chryseum is a widespread orchid from continental tropical Asia and Taiwan with a confused taxonomical history. In addition to its horticultural merits and its use in Traditional Chinese Medicine, this species has significant cultural importance among the Tsou people of Taiwan. Notes on pollination, cultivation, taxonomy, distribution,

1177. Streptocarpus aylae T.J.Edwards

open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Streptocarpus aylae T.J.Edwards, a spectacular, rosette forming herbaceous perennial from cliffs of the Msikaba River in Pondoland, Eastern Cape Province, South Africa is illustrated and discussed. The species is known from only two sites and is highly localised, growing in humus rich cracks and crevices on sandstone cliffs.

1173. Ipomoea pandurata (L.) G. Mey

open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Ipomoea pandurata is a Morning Glory from North America which develops a large storage root. There is much uncertainty about its discovery before its formal description in the middle of the 18th century. Originally described as a Convolvulus, almost a hundred years passed before its recognition as a species of Ipomoea.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Natural Parasitism of Nezara viridula (Linnaeus) (Hemiptera: Pentatomidae) by Trichopoda pictipennis Bigot (Diptera: Tachinidae) in an Organic Strawberry Field in Germany

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Natural parasitism of the invasive southern green stinkbug was recorded in an organic strawberry cropping system in southwestern Germany. The tachinid fly Trichopoda pictipennis shows successful establishment and field activity, indicating ongoing range expansion.

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 2. Methods to Improve Overwintering, Adult Emergence and Longevity

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Successful rearing of Istocheta aldrichi, a tachinid parasitoid of invasive Japanese beetle, depended on conditions before, during, and after overwintering. Longer cold exposure increased adult emergence and accelerated post‐diapause development. Early transfer of puparia to cool conditions improved survival, while spring temperature manipulation ...

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

open access: yesEcological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

open access: yesEcological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees

open access: yesEcological Entomology, EarlyView.
We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...
