Common ragweed, Ambrosia artemisiifolia L., one of the most dangerous invasive species for its high allergenic pollen production, has been spreading in Europe since the 19th century but has not until now recruited any effective natural enemy. In its native range, North america, many insects and fungi are recorded feeding or developing on this weed, reducing common ragweed impact on human health and habitats. Some of these organisms, specific or oligophagous on A. artemisiifolia, are considered promising agents for the biological control of this weed, and in some cases they have already been introduced in other continents. Among these species, the leaf beetle Ophraella communa LeSage (Coleoptera: Chrysomelidae) was found at the beginning of august 2013 attacking common ragweed near a nursery in Galliate (Novara province - piedmont Region). Field surveys were carried out from august to November in various piedmont counties to document the spread of this recently introduced galerucine species. Data are reported regarding the leaf beetle’s morphology, biological cycle, spread, hosts and natural enemies in the new range. Prospects for the biological control of common ragweed in Europe are also discussed.

Ophraella communa LeSage, 1986, a leaf beetle native to North America, is recorded for the first time from Hungary. Several specimens were found on a degraded meadow in the outskirts of Budapest. Its importance in suppressing its main host plant, common ragweed (Ambrosia artemisiifolia L.), is shortly discussed, as well as the potential problems it can cause in plant protection.

Ophraella Communa

The common ragweed Ambrosia artemisiifolia has spread throughout Europe since the 1800s, infesting croplands and causing severe allergic reactions. Recently, the ragweed leaf beetle Ophraella communa was found in Italy and Switzerland; considering that it feeds primarily on A. artemisiifolia in its invaded ranges, some projects started biological control of this invasive plant through the adventive beetle. In this context of a ‘double’ invasion, we assessed the influence of climate change on the spread of these alien species through ecological niche modelling. Considering that A. artemisiifolia mainly lives in agricultural and urbanized areas, we refined the models using satellite remote-sensing data; we also assessed the co-occurrence of the two species in these patches. A. artemisiifolia is predicted to expand more than O. communa in the future, with the medium and high classes of suitability of the former increasing more than the latter, resulting in lower efficacy for O. communa to potentially control A. artemisiifolia in agricultural and urbanized patches. Although a future assessment was performed through the 2018 land-cover data, the predictions we propose are intended to be a starting point for future assessments, considering that the possibility of a shrinkage of target patches is unlikely to occur.

In greenhouse studies, control of common ragweed (Ambrosia artemisiifoliaL. ♯ AMBEL) and common cocklebur (Xanthium pensylvanicumWallr. ♯ XANPE) was achieved whether or not soybeans [Glycine maxL. (Merr.) ‘Ransom’] partially shielded the weeds from foliar applications of acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid}. Excellent control (> 90%) of common ragweed was obtained in the greenhouse 2 and 4 weeks after plant emergence. Best control (> 90%) of common cocklebur was obtained 2 weeks after plant emergence. A simulated rainfall of 0.6 cm occurring 1 min after acifluorfen application did not decrease control or fresh weight of common ragweed in greenhouse studies. The weed control efficiency of acifluorfen on common cocklebur was reduced when the herbicide was applied intermittently within 6 h of the 0.6-cm simulated rainfall. The weed control efficiency of acifluorfen on both weed species was also reduced when the herbicide was applied intermittently within 6 to 12 h of a 1.3-cm simulated rainfall in greenhouse studies. In field studies, 2.5 cm of simulated rainfall within 12 to 24 h after acifluorfen application reduced control of common ragweed.

Ambrosiaartemisiifolia(common ragweed) is an invasive species native to North America and was accidentally introduced to Europe in the 19thcentury. Widespread in disturbed habitats, it is a major weed in spring-sown crops and it causes serious allergic rhinitis and asthma due to its allergenic pollen. The aim of this research was to analyse the effects of both competitive vegetation and herbivory byOphraellacommunato controlA.artemisiifoliain an agricultural area of north-western Italy. Hayseed mixtures, both over-seeded over the resident plant community or after ploughing, when seeded before the winter season, were able to suppress the establishment ofA.artemisiifoliaas well as to reduce its growth in terms of plant height and inflorescence size. Defoliation ofA.artemisiifoliabyO.communaat the end of the growing season was conspicuous but most of the plants still produced flowers and seeds. However, significantO.communaattack was recorded for reproductive structures. As for non-target species,O.communawas mainly recorded on Asteraceae, with low density and low degree of damage. Reduction of inflorescence size due to competitive vegetation and damage to male flowers byO.communamay diminish the amount of available pollen. The results of this study may be useful for the implementation of management measures to controlA.artemisiifoliain agricultural areas using mixtures of native species.
