A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

Insect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

Insect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

Archaeometry, EarlyView.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

Archaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.
