Pheromone stereochemical specificity in the biology of the bean beetle Acanthoscelides obtectus

open access: yesAgricultural and Forest Entomology, EarlyView.
Abstract The dried bean beetle, Acanthoscelides obtectus, is a serious pest of legume crops, particularly Phaseolus vulgaris beans, and its management is challenging due to the beetle's cryptic larval stage. The major male‐produced pheromone of A. obtectus is methyl (E,R)‐2,4,5‐tetradecatrienoate, crucial for female attraction, with the (S)‐enantiomer ...

For special purposes only: Ceramic casting moulds from the late Bronze and Early Iron Age metallurgical workshop in Grzybiany (SW Poland)

open access: yesArchaeometry, Volume 67, Issue 2, Page 482-501, April 2025.
Abstract Ceramic moulds are regarded as highly specialised, refractory tools used in metallurgy, yet their production process still needs clarification. Our research aimed to characterise the stages of operational chains applied in mould manufacture. The evidence comes from the Late Bronze and Early Iron Age lake settlement in Grzybiany in SW Poland ...

Advancements in radiocarbon dating: An overview of its impact on Mexican archaeology

open access: yesArchaeometry, EarlyView.
Abstract In this article, we provide a concise historical summary tracing the evolution of radiocarbon dating techniques in Mexico and Central America. We explore the contributions of early pioneers who first employed radiocarbon dating methods, leading to the establishment of a Mexican accelerator mass spectrometry laboratory. The study highlights its

Dating an ancient spring tunnel using archaeological artefacts functioning as nuclei of cave pearls

open access: yesArchaeometry, Volume 67, Issue 3, Page 748-772, June 2025.
Abstract Cave pearls are spherical concentric speleothems growing radially around nuclei in shallow pools saturated with calcite. They are very rare in the Southern Levant. We present a unique assemblage of 50 cave pearls found in the Iron Age Joweizeh artificial spring tunnel in the Jerusalem Hills of Israel. Some of these deposits represent the first
