1173. Ipomoea pandurata (L.) G. Mey

Curtis'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

Entomologia 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.

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

Entomologia 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 ...
