A study on the Neotropical Anthaxiini (Coleoptera,Buprestidae, Buprestinae)

Revision of the Neotropical genera of the subtribe Anthaxiina Gory & Laporte, 1839 (Coleoptera, Buprestidae, Buprestinae, Anthaxiini). Five new genera are described: Anthaxita gen. n., Charlesina gen. n., Cobosina gen. n., Marikia gen. n. and Sanchezia gen. n. Genus Agrilaxia Kerremans, 1903 is divided into two subgenera: Agrilaxia and Costiptera subgen. n. and the genus Bilyaxia Hołyński, 1989 is divided into three subgenera: Bilyaxia, Paraguayetta subgen. n. and Tomasia subgen. n. One new species is described: Anthaxita peruviana sp. n., and two informal species-groups are suggested within Agrilaxia (Costiptera subgen. n.): Agrilaxia (Costiptera) modesta (Kerremans, 1897) species-group and Agrilaxia (Costiptera) occidentalis (Kerremans, 1900) species-group. Lectotype is designated for Agrilaxia mrazi Obenberger, 1932. A key of all genera/subgenera is provided and all treated taxa are illustrated.     

Track analysis of the Mexican species of Buprestidae (Coleoptera): testing the complex nature of the Mexican Transition Zone

Aim  We analysed the geographical distributions of species of Buprestidae (Coleoptera) in Mexico by means of a panbiogeographical analysis, in order to identify their main distributional patterns and test the complex nature of the Mexican Transition Zone, located between the Nearctic and Neotropical regions.
Location  Mexico.
Methods  The geographical distributions of 228 species belonging to 33 genera of Buprestidae were analysed. Localities of the buprestid species were represented on maps and their individual tracks were drawn. Based on a comparison of the individual tracks, generalized tracks were detected and mapped. Nodes were identified as the areas where generalized tracks converged.
Results  Thirteen generalized tracks were obtained: one was restricted to the Mexican Transition Zone and five to the Neotropical region (Antillean and Mesoamerican dominions), a further two occurred in both the Nearctic region (Continental Nearctic dominion) and the Mexican Transition Zone, and a further five in both the Neotropical region (Mesoamerican dominion) and the Mexican Transition Zone. Seven nodes were identified at the intersections of the generalized tracks – in the Mesoamerican dominion (Mexican Pacific Coast, Mexican Gulf and Chiapas biogeographical provinces) and the Mexican Transition Zone (Trans-Mexican Volcanic Belt, Balsas Basin and Sierra Madre Oriental biogeographical provinces).
Main conclusions  We conclude that the geographical distribution of Buprestidae is mainly Neotropical, corresponding to the Mesoamerican dominion and the Antillean dominion of the Neotropical region, and the Mexican Transition Zone. Most of the generalized tracks and nodes correspond to the Mexican Transition Zone, thus confirming its complex nature. We suggest that the nodes we have identified could be particularly important areas to choose for conservation prioritization.

Field and tree distribution of Capnodis tenebrionis (Linnaeus, 1767) (Col., Buprestidae) adults in an apricot orchard in Italy

A study was conducted into the spatio–temporal distribution of adult Capnodis tenebrionis (Linnaeus, 1767) in an apricot orchard in Sicily (Italy) using inverse distance squared weighting (IDW), a spatial interpolation technique to create a distribution map of adults in the orchard. The study was conducted throughout the period of presence of the adult in the field and it investigated distribution on individual plants with regard to the observed height on the crown and exposure to the sun’s rays. The variation is gradual in the distribution of the buprestid in the field and the areas with the greatest exposition to the sun (south‐east) were marked by the highest densities. The presence of the pest was also found to be higher in those parts of the crown most exposed to the sun; moreover, the position in relation to the ground varied constantly and was increasingly linked to time and temperature. The data obtained confirmed the distinct thermal demands of the species and provided useful information on both sampling and control.

Field trapping of the flathead oak borer Coroebus undatus (Coleoptera: Buprestidae) with different traps and volatile lures

The flathead oak borer Coroebus undatus F. (Coleoptera: Buprestidae) is one of the primary pests of cork oak Quercus suber L. in the Mediterranean region causing great economic losses to the cork industry. Very little is known about its biology and behavior and, so far, no control measures have been established. We present the results of a pilot study aimed to develop an efficient trapping method for monitoring this harmful pest. In a 3‐year field study, purple‐colored prism traps baited with a mixture of green leaf volatiles (GLVs) from the host have been shown the most effective combination to catch C. undatus adults (solely females) compared to other trap and lure types tested. Wavelength and reflectance measurements revealed that purple traps exhibit reflectance peak values similar to those found in the abdominal and elytral cuticle of both sexes, suggesting the involvement of visual cues for mate location in this species. The data presented are the first to demonstrate captures of adults of the genus Coroebus by an attractant‐based trapping method.

Morphology of female reproductive system of Mediterranean flatheaded peachborer,Capnodis tenebrionis (Linnaeus, 1761) (Coleoptera: Buprestidae)

Capnodis tenebrionis causes damage in many species of Rosaceae. The present study investigates on the morphology of the female reproductive system of C. tenebrionis. The female reproductive system of C. tenebrionis has a pair of ovaries, lateral oviducts, a common oviduct, spermatheca, and bursa copulatrix. Each ovary in C. tenebrionis consists of approximately 24 telotrophic meroistic type ovarioles. The ovarioles of C. tenebrionis have four regions (terminal filament, tropharium, vitellarium, and pedicel). Tropharium have trophocytes, young oocytes, and prefollicular cells. Vitellarium consists of previtellogenic, vitellogenic, and choriogenic oocytes. Previtellogenic oocyte is surrounded by cylindrical epithelial cells. Its ooplasm is homogeneous and basophilic. In vitellogenic oocyte, there are intercellular spaces between monolayered follicle cells. Its ooplasm has yolk granules and lipid droplets. Choriogenic oocyte are surrounded by chorion and single-layered cylindrical cells. There are yolk granules and lipid droplets in its ooplasm which is asidophilic. In C. tenebrionis female, spermatheca and bursa copulatrix wall is surrounded by thin cuticular intima, monolayer epithelial, glandular cells, and muscle layer. Spermatheca lumen contains a large number of spermatozoa. Bursa copulatrix lumen is filled with secretory material. This study may be useful in terms of the morphology of mature female reproductive organs of Buprestidae and other coleopteran species.
