Weevils and Plants: Phylogenetic Versus Ecological Mediation of Evolution of Host Plant Associations in Curculioninae (Coleoptera: Curculionidae)

Abstract

The pupae of Otiorhynchus (Arammichnus) dieckmanni Magnano, 1979, O. (s.str.) tenebricosus (Herbst, 1784) form lugdunensis Boheman, 1843, Peritelus sphaeroides Germar, 1824, Strophosoma (Neliocarus) c.f. sus Stephens, 1831 and Tanymecus (s. str.) palliatus (Fabricius, 1787) are described and illustrated for the first time. The pupae of Barypeithes (Exomias) pellucidus (Boheman, 1834), Brachyderes (s. str.) incanus (Linnaeus, 1758), Liophloeus (s. str.) tessulatus (Müller, 1776), Phyllobius intrusus Kôno, 1948 (= Parascythopus exsulans Heijerman & Magnano , 2000) and Phyllobius (s. str.) pyri (Linnaeus, 1758) are redescribed and illustrated. Characteristic features including chaetotaxy, habitus and measurements are given. Pupae of the genera Peritelus, Strophosoma, and Tanymecus are described for the first time. Keys to the pupae of 14 genera of broad-nosed weevils, and to several species of Phyllobius and Otiorhynchus are also presented.

Mauritinus seferi Bondar, 1960: bionomy, description of immature stages and redescription of adult (Coleoptera, Curculionidae)

“…These observations do not seem to us to be the result of chance, but indicate that females lay two eggs systematically in each fruit and should leave some type of chemical sign to prevent other females of M. seferi and other species of insects from laying eggs on the same fruits. This same kind of behavior has already been observed in others species of Curculionidae, and it seems to be very important to avoid competition for space, food and to prevent the complete destruction or rottenness of the fruits before the pupation of larvae (ANDERSON 1993).…”

CURCULIONOIDEA FROM GOLESTAN PROVINCE, NORTHERN IRAN (Coleoptera)

“…The larvae are short, fleshy, apodous, and live as endophytes as a rule, only immature stages of a few species being ectophagous. This superfamily includes a large number of agricultural and forest pests (Bajtenov 1974;Anderson 1993Anderson , 1995.…”

Morphological and Molecular Perspectives on the Phylogeny, Evolution, and Classification of Weevils (Coleoptera: Curculionoidea): Proceedings from the 2016 International Weevil Meeting

“…Blepharida Chevrolat (Chrysomelidae: Chrysomelinae) was given as an example of when host associations are better explained by host plant allelochemicals than taxonomy [73]. Species of various semiaquatic weevils (e.g., Bagous Germar, Notiodes Schoenherr, Listronotus Jekel) are generally associated with unrelated plants likely because these groups of plants live in the same habitat as the weevils [74]. Weevil associations with plants in the family Cyclanthaceae have a recently elucidated complex history with no simple cophyletic basis or host range pattern [75].…”
