“…Most authors situate the origin of A. obtectus in Mesoamerica (e.g. Labeyrie 1990). Based on this assumption, entomologists and agronomists have started scientific programs in Mexico and Central America (south to northern Colombia) to find candidate parasitoid species for biological control (e.g.…”

Ancient and recent evolutionary history of the bruchid beetle, Acanthoscelides obtectus Say, a cosmopolitan pest of beans

et al. 2005

Acanthoscelides obtectus Say is a bruchid species of Neotropical origin, and is specialized on beans of the Phaseolus vulgaris L. group. Since the domestication and diffusion of beans, A. obtectus has become cosmopolitan through human‐mediated migrations and is now a major pest in bean granaries. Using phylogeographic methods applied to mitochondrial DNA (mtDNA) and nuclear microsatellite molecular markers, we show that the origin of this species is probably further south than Mesoamerica, as commonly thought. Our results also indicate that A. obtectus and its Mesoamerican sister species Acanthoscelides obvelatus, two morphologically close species differing principally in voltinism, speciated in allopatry: A. obtectus (multivoltine) arising in Andean America and A. obvelatus (univoltine) in Mesoamerica. In contrast to Mesoamerica where beans fruit once yearly, wild beans in Andean America fruit year‐round, especially in regions showing little or no seasonality. In such habitats where resources are continuously present, multivoltinism is adaptive. According to existing hypotheses, multivoltinism in A. obtectus is a new adaptation that evolved after bean domestication. Our data suggest the alternative hypothesis that multivoltinism is an older trait, adapted to exploit the year‐round fruiting of wild beans in relatively aseasonal habitats, and allowed A. obtectus to become a pest in bean granaries. This trait also permitted this species to disperse through human‐mediated migrations associated with diffusion of domesticated beans. We also show that diversity of Old World A. obtectus populations can be quite well explained by a single colonization event about 500 bp. Human‐mediated migrations appear not to be rare, as our results indicate a second more recent migration event from Andean America to Mexico.

“…The evolutionary history of Acanthoscelides obtectus has been very dynamic. Recent analysis on several mitochondrial genes (12s rRNA, 16s rRNA, COI) unambiguously confirmed the place of origin of A. obtectus in Central America [37,38] and also recognized that both pre- and post-Columbian range expansions played important roles in shaping current, worldwide distribution of this insect [39]. Additionally, the evolution of multivoltinism (i.e., the ability to produce multiple generations per year) is another important characteristic that enabled A. obtectus to expand the range and be highly competitive when invading stored seeds [37,40].…”

Effective pest management strategies for a targeted pest species must rely on accurate, reliable and reproducible estimates of population dynamics. Importance of such approaches is even more conspicuous when assessing pest’s potential to utilize other stored products. Using an experimental evolution approach, we have focused our attention on a common bean pest, the seed beetle (Acanthoscelides obtectus). We looked into the potential to invade and sustain population growth on two suboptimal host plants (chickpeas and mung beans). Such an approach simulates steps of the host-shift process in storages. By analyzing population dynamics during initial encountering with a new host plant, we detected a population drop for both novel hosts. However, transgenerational development in a novel environment resulted in a constant population growth in chickpeas, but not in mung bean populations. Reversal of chickpea selected populations to original host plant has led to a severe decrease in population parameters due to low viability of immatures, while the opposite trend was detected in mung bean populations. This paper highlights the importance of good practice in estimating population dynamics for economically important species. With special emphasis on storage pest species, we discuss how this approach can be useful for estimating invading potential of pest insects.

In this paper new data on allochtonous and invasive invertebrate species: Arion (Arion) cf. vulgaris Moquin-Tandon 1855, Cornu aspersum (O.F. Muller, 1774), Harmonia axyridis (Pallas, 1773), Acanthoscelides obtectus (Say, 1831), Trogoderma variabile Ballion, 1878, Stegobium paniceum (Linnaeus, 1758), Oxycarenus (s.str.) lavaterae (Fabricius, 1787), Corythucha ciliata (Say, 1832), Leptoglossus occidentalis Heidemann, 1910, Ceroplastes japonicus (Green, 1921), Pseudaulacaspis pentagona (Targioni Tozzetti, 1886) MacGillivray, 1921, Tuta absoluta (Meyrick, 1917) and Frankliniella occidentalis (Pergande, 1895) from Macedonia are presented. The study represents faunistic data synthesis from different parts of Macedonia, based on collecting efforts of several taxonomic experts. The results of the study help to outline the composition of non-native and invasive invertebrate fauna and to narrow gaps concerning the knowledge of their distribution and introduction in Macedonia.
