“…This remarkably diverse host repertoire contrasts with what is expected at this taxonomic scale in most weevils, especially in this subfamily: the Curculioninae (e.g. Oberprieler et al, 2007;Hernández-Vera et al, 2019;Haran et al, 2023). Exploring the phylogenetic relationship within this group and their ancestral host plant associations is thus crucial to appreciate the role that parasitic plants may play in this unusual evolution pattern.…”

“…Additional individuals were sampled in seven tribes (Anthonomini, Cionini, Curculionini, Derelomini, Erirhinini, Rhamphini and Styphlini) related to Smicronychini to serve as outgroups for phylogenetic inferences. These tribes were selected based on the most recent and comprehensive phylogenomic study of the Curculioninae subfamily (Haran et al, 2023). COI dataset -COI sequences have been extracted from AHE sequencing data using MitoFinder v1.4.1 (Allio et al, 2020).…”

Phytophagous insects have specialized on virtually every plant lineage. Parasitic plants, however, are uncommon hosts. Among insects, only a single lineage of weevils, the Smicronychini, has successfully radiated on both parasitic and non-parasitic plants in a large panel of distantly related Asterid families. This unusual pattern suggests that major host plant shifts have occurred over the course of their diversification. Through the analysis of a phylogenomic dataset, we reconstruct for the first time their evolutionary history and ancestral host plant associations. Our results show that independent host plant shifts occurred both from parasitic to non-parasitic hosts and between distinct parasitic lineages. These results suggest that host shift mechanisms can be driven by ecological opportunities provided by plant-plant interactions. This first evidence of extreme insect host plant shifts mediated by parasitic plant-plant interactions emphasizes the core importance of ecological interactions as driving forces behind insect host plant shifts.

“…Most recently, Haran et al (2023b), in studying phylogenetic relationships within the subfamily Curculioninae, have shown that the Derelomini is not monophyletic but comprises four, unrelated lineages. Three of these lineages correspond to the subtribes recognized by Franz (2006)-Derelomina, Notolomina, and Phyllotrogina.…”

Pollination Systems of Palms (Arecaceae)

A review is given of pollination systems in the palm family (Arecaceae). Pollination studies of 149 species (6% of the total number) in 60 genera (33% of the total number) are reviewed. The majority of these studies (75%) are of Neotropical palms. In the sample of 149 species, approximately 52% are beetle-pollinated, 27% bee-pollinated, 7% fly-pollinated, 5% thrips pollinated, 5% wind pollinated, 3% moth-pollinated, and 1% mammal-pollinated. A few other species may be bird-pollinated. Adaptations of inflorescences and flowers to pollinators are not readily apparent except for a general tendency for bee-/fly-pollinated species to have longer, open inflorescences and beetle-pollinated species to have shorter, condensed inflorescences. Classical pollination syndromes are not useful in describing, classifying, or predicting palm pollination systems because of numerous exceptions. The degree to which palm pollination systems may be considered specialized or generalized is unclear. There appear to have been numerous, bidirectional shifts in palms between beetle pollination and bee/fly pollination, and less often shifts to other pollinators. Beetle-pollinated inflorescences are usually visited by bees, and bee-pollinated inflorescences are usually visited by beetles. It seems likely that many species of palm, irrespective of pollinator, have their inflorescences used as brood-sites by beetles.

The rape stem weevil (Ceutorhynchus asper Roel.) and its close relatives primarily breed on cruciferous plants and cause severe damage to rapeseed production. However, their genetic and molecular information is still scarce. Here, we generated mitogenomes for both C. asper and Ceutorhynchus albosuturalis. The lengths of the 2 mitochondrial genomes are 14,207 bp (C. asper) and 15,373 bp (C. albosuturalis), and both weevils exhibit identical numbers of protein-coding genes with the absence of trnI. A + T contents for both mitogenomes are high (80% and 79.9%, respectively). Haplotype and genetic distance analyses showed that the genetic differentiation of C. asper populations in northwestern China is low. Based on 5 datasets from mitogenomes, phylogenetic analyses with maximum-likelihood and Bayesian methods show that both species (C. asper and C. albosuturalis) fall in the CCCMS clade (Curculioninae, Conoderinae, Cossoninae, Molytinae, and Scolytinae) of Curculionidae and belong to clades H and I of the genus Ceutorhynchus, respectively. Larvae of the clade H weevils mainly are borers in petioles or stems of cruciferous plants, while larvae of the clade I weevils mainly inhabit the fruits of the same plants, suggesting that ecological niche specialization can play a critical role in the diversification of Ceutorhynchus species. This study generates baseline molecular and genetic information for future research of Ceutorhynchus-related taxa and provides insights into the phylogeny and evolution of Curculionidae.
