Faunal, phenological and bibliographical information on Latvian Eumolpinae are presented in the current paper. Bibliographycal analysis on this leaf-beetles subfamily in Latvia is made for the first time. An annotated list of Latvian Eumolpinae including 4 species of 3 genera is given.

Of them, 11 species of 6 genera are 1997; Telnov & Kalniņš 2003; Telnov et al. 2006, known from eastern Europe (Bieńkowski 2004), 2010; Bukejs & Telnov 2007). and only 4 species of 3 genera – from Fennoscandia and Baltiae (Silfverberg 2004).

Coleoptera Chrysomelidae) of Sicily: Recent Records and Updated Checklist
DOI: 10.1478/AAPP.982A7 AAPP j Atti della Accademia Peloritana dei Pericolanti Classe di Scienze Fisiche, Matematiche e Naturali ISSN 1825-1242 Vol. 98, No. 2, A7 (2020) THE CASSIDINAE AND CRYPTOCEPHALINI (COLEOPTERA CHRYSOMELIDAE) OF SICILY: RECENT RECORDS AND UPDATED CHECKLIST COSIMO BAVIERA a∗ AND DAVIDE SASSI b ABSTRACT. This paper compiles an updated checklist of the Sicilian Cassidinae and Cryptocephalini species (Coleoptera: Chrysomelidae, Cassidinae and Cryptocephalinae) starting from a critical bibliographic screening and adding new material, mainly collected by the first author in the last few decades. A total of 61 species is reported, withnew data for many rarely collected taxa. The provided data expand the known distribution of many uncommon species in Sicily. Two species are recorded for the first time: Cassida inopinata Sassi and Borowiec, 2006 and Cryptocephalus (Cryptocephalus) bimaculatus Fabricius, 1781 and two uncertain presences are confirmed: Cassida deflorata Suffrian, 1844 and Cassida nobilis Linné, 1758. The presence of other sixteen species is considered questionable and needs further confirmation. 1. Introduction Leaf beetles are all phytophagous Coleoptera. They are usually of a rather stout build, with a rounded or oval shape, often brightly coloured or with metallic hues. Worldwide some 32500 species in 2114 genera of Chrysomelidae have been described (Slipi´ nski´ et al. 2011), the majority of which occur in the tropics as is the case with numerous other Coleoptera families. Currently, the leaf beetle subfamily Cassidinae comprises the tortoise beetles (Cassidinae s. str.) and the hispine beetles (Hispinae s. str.) (Borowiec 1995; Hsiao and Windsor 1999; Chaboo 2007). So far, the Cassidinae list about 6300 described species within more than 340 genera, being the second most speciose subfamily of leaf beetles (Borowiec and Swi˛etoja´ nska´ 2014). -

In the current work all available bibliography on Latvian leaf-beetles are reviewed and analyzed.

BM Gıda Hakkı Özel Sözcüsü’nün 2017 tarihli raporu, pestisit kullanımının insan hakları, insan sağlığı (işçiler, işçi aileleri, dışarıdan insanlar, mukimler, ve tüketiciler) ve çevre üzerindeki zararlı etkilerini vurgulamaktadır. Rapor, ayrıca, pestisit kullanımına bağlı yoğun tarımın, dünyadaki açlığı azaltmadığını da ortaya 1 çıkarmıştır . Herbisitler, tarım ve bahçecilikte daha fazla su, besin ve güneş ışığı için ürünler ve mera bitkileriyle rekabet ederek, tarım ve hayvancılıkta kayba yol açan, dolayısıyla kârı düşüren yabancı otlarla mücadelede kullanılmaktadır. Glifosat başta olmak üzere, herbisitlerin en yaygın kullanıldığı ikinci amaç ise, toprağın işlenmediği veya az işlendiği sistemlerde, hasat öncesinde ve sonrasında arazideki tüm bitki örtüsünü yok etmektir. Ayrıca, hasat öncesi tahıl ve tohum bitkilerini olgunlaştırmak ve kurutmak için de uygulanır. Tarım dışında ise, istilacı bitki türlerinden kurtulmak, kamusal alanların yönetiminde estetik amaçlar veya tehlikeli durumları ortadan kaldırmak niyetiyle (ör. -

In the present work, we have characterized the chromosomes of 13 Cassidinae beetles, belonging to four tribes, the broad aim being to increase the cytogenetic data and establish the mechanisms involved in chromosome evolution of this sub- family, which appear to be conserved karyotypically, i.e. 2n = 16 + Xyp. The analysis of mitotic and meiotic cells revealed a high diversity of diploid numbers (2n = 18, 2n = 22, 2n = 26, 2n = 32, 2n = 36, 2n = 40, 2n = 42), and the presence of sex chromosome system of the Xyp type in most species, with the exception of two representatives that exhibited Xyr and XY systems. C-banding showed constitutive heterochromatin predominantly localized in the pericentromeric region of the chromosomes, but differences regarding the number of chromosomes with positive C-bands, intensity of the blocks, and presence of additional bands in auto- somes and/or sex chromosomes were observed among the species investigated. -
Évaluation De Méthodes De Lutte Aux Plantes Envahissantes En Tourbière: Les Cas De La Quenouille Et Du Roseau
Évaluation de méthodes de lutte aux plantes envahissantes en tourbière: les cas de la quenouille et du roseau Mémoire François Messier Maîtrise en biologie végétale Maître ès sciences (M. Sc.) Québec, Canada © François Messier, 2017 Évaluation de méthodes de lutte aux plantes envahissantes en tourbière: les cas de la quenouille et du roseau Mémoire François Messier Sous la direction de : Line Rochefort, directrice de recherche Claude Lavoie, codirecteur de recherche Résumé La quenouille à feuilles larges (Typha latifolia, une plante indigène d’Amérique du Nord) et le roseau commun (Phragmites australis, haplotype M, le génotype exotique d’Eurasie) sont souvent observés dans les tourbières à sphaignes à la suite des activités d’extraction de la tourbe. L’envahissement des milieux humides par ces plantes peut nuire au rétablissement des communautés végétales typiques des tourbières et potentiellement réduire la capacité de ces écosystèmes à stocker le carbone. De plus, les graines produites en grandes quantités peuvent être responsables de la contamination de la tourbe extraite des terrains voisins. Au Québec, des populations denses de quenouille et de roseau ont été répertoriées récemment dans deux bogs de la région du Bas-Saint-Laurent autrefois utilisés pour l’extraction de la tourbe. Le but de ce projet était d’évaluer et tester des méthodes pour lutter contre la propagation de la quenouille et du roseau en tourbière. Différentes méthodes de lutte telles que la fauche des tiges, le bâchage et la revégétalisation ont été testées dans deux sites, Bois-des-Bel (BDB, une tourbière restaurée) et Saint-Alexandre-de-Kamouraska (SAK, une tourbière non restaurée).
