- G3: Genes, Genomes, Genetics

TL;DR: Comparing the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation.

The Role of Minor Pheromone Components in Segregating 14 Species of Longhorned Beetles (Coleoptera: Cerambycidae) of the Subfamily Cerambycinae

Lawrence M. Hanks, +7 more

- Journal of Economic Entomology

TL;DR: The antagonistic effects of minor compounds produced by heterospecific males suggest that these compounds serve to maintain prezygotic reproductive isolation among some species that share pheromone components.

Responses of two parasitoids, the exotic Spathius agrili Yang and the native Spathius floridanus Ashmead, to volatile cues associated with the emerald ash borer, Agrilus planipennis Fairmaire

- Biological Control

TL;DR: Evaluated responses to their host complex, Fraxinus pennsylvanica stem tissue, and an A. planipennis larva within a stem found no evidence that oviposition influences attraction by S. agrili, suggesting other forms of experience should be evaluated for potential sources of learned cues.

(2E,6Z,9Z)-2,6,9-Pentadecatrienal as a Male-Produced Aggregation-Sex Pheromone of the Cerambycid Beetle Elaphidion mucronatum

Jocelyn G. Millar, +6 more

- 18 Nov 2017

- Journal of Chemical Ecology

TL;DR: Unexpectedly, adults of the cerambycine Xylotrechus colonus (F.) were attracted in significant numbers to a blend of 3-hydroxyhexan-2-one and (2E,6Z,9Z)-2,6,9-pentadecatrienal, even though there is no evidence that this species produces the latter compound.

The Rare North American Cerambycid Beetle Dryobius sexnotatus Shares a Novel Pyrrole Pheromone Component with Species in Asia and South America.

- Journal of Chemical Ecology

TL;DR: This study attests to the effectiveness of pheromone-baited traps in capturing rarely encountered species of cerambycids, and provides further evidence that pyrrole represents another conserved peromone motif within the CerambyCinae, now having been found in representatives of five ceram bycid tribes from three continents.
