Galerucella (Coleoptera: Chrysomelidae) is a leaf beetle genus that has been extensively used for ecological and evolutionary studies. It has also been used as biological control agent against invading purple loosestrife in North America, with large effects on biodiversity. Here, we report genome assembly and annotation of three closely related Galerucella species: G. calmariensis, G. pusilla, and G. tenella. The three assemblies have a genome size ranging from 460 to 588 Mbp, with N50 from 31,588 to 79,674 kbp, containing 29,202 to 40,929 scaffolds. Using an ab initio evidence-driven approach, 30,302 to 33,794 protein-coding genes were identified and functionally annotated. These draft genomes will contribute to the understanding of host-parasitoid interactions, evolutionary comparisons of leaf beetle species and future population genomics studies.

Background: The univoltine leaf beetle (Curtis, 1837b) is native to the Palaearctic Region from Japan to western Europe.This species was previously evaluated as a potential biological control agent against invasive populations of the woodland weed (Bieb.) Cavara & Grande (Brassicaceae) in North America, but rejected because it could harm native and at-risk populations of Brassicaceae.

Amphitetranychus viennensis, a destructive pest mite of fruit plants in Europe and Asia, poses a serious challenge due to its adaptability and resistance to multiple acaricides. RNA interference (RNAi)-based technologies offer a promising alternative to address this emerging issue. In this study, we screened for candidate genes that can be targeted for spray-induced gene silencing (SIGS).

Background: Acanthacoccus lagerstroemiae (crape myrtle bark scale, CMBS) is an exotic scale insect that feeds on the sap of crape myrtle trees. Heavy infestations of CMBS reduce flowering and honeydew promotes sooty mold growth on the leaves and branches, reducing the aesthetic value of crape myrtle trees in urban landscapes. Lady beetles (Coleoptera: Coccinellidae) are generalist predators that feed on CMBS.
