An Easy Method to Sample Headspace Pheromones in the Field

Ethology, Volume 132, Issue 5, Page 365-371, May 2026.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Chromosome‐Scale Haplotype Genome Assemblies for the Australian Mango ‘Kensington Pride’ and a Wild Relative, Mangifera laurina, Provide Insights Into Anthracnose‐Resistance and Volatile Compound Biosynthesis Genes

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3172-3188, May 2026.
ABSTRACT Mango (Mangifera indica) is one of the most popular fruits cultivated in tropical and subtropical regions of the world. The availability of reference genomes helps to identify the genetic basis of important traits. Here, we report assembled high‐quality chromosome‐level genomes for the Australian mango cultivar ‘Kensington Pride’ and M ...
