Ingestible insecticides for spotted wing Drosophila control: a polyol, Erythritol, and an insect growth regulator, Lufenuron
TL;DR: Bioassays tested insecticidal activity of Erythritol from the nutritive sweetener, Truvia, and an insect growth regulator, Lufenuron, against life stages (eggs, larvae, pupae, adults) of Drosophila melanogaster and Drosophile suzukii, the spotted wing Drosphila (SWD).

Biology of Parasitoids (Hymenoptera) Attacking Dasineura oxycoccana and Prodiplosis vaccinii (Diptera: Cecidomyiidae) in Cultivated Blueberries
TL;DR: Five species of solitary endoparasitoids that killed 30–40% of midges were identified using a combination of laboratory rearing and mitochondrial DNA analysis of field samples, indicating the potential for natural control of midge populations.

TL;DR: In this article, the major phenolic compounds in muscadine juice, pulp and skins were identified by their retention times and characteristic spectra, and the presence of ellagic acid, myricetin, quercetin and kaempferol was identified.
Erythritol and Lufenuron Detrimentally Alter Age Structure of Wild Drosophila suzukii (Diptera: Drosophilidae) Populations in Blueberry and Blackberry.

TL;DR: Erythritol and lufenuron were equally efficacious compounds as a D. suzukii ovicide and larvicide, but they did not display additive or synergistic activity.

Variation in nuclear DNA content and chromosome numbers in blueberry
Hamidou F. Sakhanokho,Timothy A. Rinehart,Stephen J. Stringer,M. Nurul Islam-Faridi,Cecil T. Pounders +4 more
TL;DR: Blueberry species have many different genome sizes, presumably due to differing ploidy levels and/or DNA content, and DNA content in 77 blueberry taxa including 11 species and 64 hybrid cultivars is determined.
