“…The terminology used by Wattanapongsiri (1966), to describe larval structures and chaetotaxy of Rhynchophorus and Dynamis, differs in some important aspects with the one adopted in the present work and other comparative studies (e.g., see Marvaldi, 1999;May, 1994;Chamorro & Huang, 2019). Among the differences worth to note are those involving the "anterolateral setae of epipharynx (als)", which in Wattanapongsiri (1966) are named "lateral setae of labrum" and, as additional source of confusion, their counting is given in full and not for one side, as it is standard for description of bilateral structures.…”

Comparative morphology of the larvae of the palm weevils Dynamis borassi (Fabricius) and Rhynchophorus palmarum (Linnaeus) (Curculionidae: Dryophthorinae): Two major pests of peach palms in the Neotropics

The morphology of the larvae of Dynamis borassi (Fabricius) and Rhynchophorus palmarum (Linnaeus) was compared, described and illustrated. A complete definition of subtribe Rhynchophorina at the larval stage was elaborated, based on mature and submature larvae, and characters of the first instar larvae are provided for the first time. Diagnostic characters to distinguish the larvae of D. borassi and R. palmarum are mainly from the epipharynx and maxillae, but the abdominal terminal plate also provides differential features that can aid in the identification. The characterization of both species at the larval stage is expected to be useful in the implementation of new control strategies in palm plantations in South America. For practical reasons, a comparative table is appended in Spanish to serve as a quick diagnostic guide for species identification.

“…The discovery of the previously unreported behavior of cocoon construction by the preimaginal stage using plants fibers is significant because in some instances, the presence of the weevil in the plant may go unnoticed. The behavioral trait of constructing a fibrous pupal cocoon is also exhibited by most dryophthorine weevils, particularly species associated with monocots [20,21,22].…”

Elytroteinus geophilus (Lucas) is a polyphagous weevil that is widespread in the South Pacific islands and is known to cause damage to various crops with large nutrient storage structures such as kava, ginger, yellow passion fruit, yams and sweet potatoes. More significantly, E. geophilus, the Fijian Ginger Weevil, has been linked, along with two wound invading fungal pathogens, to a passion fruit collar rot in Samoa. This species is considered a high-risk insect pest and it is included in the USDA’s prioritized offshore pest list. We report on new plant hosts and behavior of this weevil. The first new host record resulted from interception of this weevil in bulbs of Tropical Spider Lily (Crinum sp.) in Alabama. This interception initiated an examination of museum specimens and the literature that resulted in a second previously unreported host record (vanilla (Orchidaceae)) and a new behavioral trait for this weevil: the use of plant fibers to spin a cocoon for pupation. A synthesis of known host plants records is reported here and suggests a preference by this weevil of starch-storing plant organs. A distribution map and a differential diagnosis of the species is also provided.

This study provides an illustrated synoptic key and comparative morphology to the 38 known larvae of dryophthorine genera representing seven subtribes in four of the five tribes: Cactophagus LeConte, Cosmopolites Chevrolat, Cyrtotrachelus Schoenherr, Diathetes Pascoe, Diocalandra Faust, Dryophthoroides Roelofs, Dryophthorus Germar, Dynamis Chevrolat, Eucalandra Faust, Eugnoristus Schoenherr, Foveolus Vaurie, Mesocordylus Lacordaire, Metamasius Horn, Metamasius (=Paramasius Kuschel), Myocalandra Faust, Nassophasis Waterhouse, Nephius Pascoe, Odoiporus Chevrolat, Phacecorynes Schoenherr, Polytus Faust, Poteriophorus Schoenherr, Rhabdoscelus Marshall, Rhinostomus Rafinesque, Rhodobaenus LeConte, Rhynchophorus Herbst, Scyphophorus Schoenherr, Sipalinus Marshall, Sitophilus Schoenherr, Sparganobasis Marshall, Sphenophorus Schoenherr, Stenommatus Wollaston, Temnoschoita Chevrolat, Trigonotarsus Guerin-Meneville, Trochorhopalus Kirsch, Tryphetus Faust, Xerodermus Lacordaire, and Yuccaborus LeConte. Only Prodioctes Pascoe was not included due to lack of specimens to examine. Seven genera are reported here for the first time. Detailed line drawings of the mouthparts of 37 genera are provided. The synoptic key is a multi-entry key, different from a traditional, single entry dichotomous key, which allows the user to identify dryophthorine larvae using any combination of characters (couplets). A total of 52 characters are included. This study provides support for the retention of Stromboscerini in the subfamily.
