Amphibians, a class of animals in global decline, are present in agricultural landscapes characterized by agrochemical inputs. Effects of pesticides on terrestrial life stages of amphibians such as juvenile and adult frogs, toads and newts are little understood and a specific risk assessment for pesticide exposure, mandatory for other vertebrate groups, is currently not conducted. We studied the effects of seven pesticide products on juvenile European common frogs (Rana temporaria) in an agricultural overspray scenario.

The Swiss weevil fauna numbers 1069 taxa, present results included. Rhinusa vestita (Germar, 1821) is recorded as new for the Swiss fauna. Records of Aspidapion validum (Germar, 1817), Ceutorhynchus resedae (Marsham, 1802), Lixus scolopax Boheman, 1835, Minyops variolosus (Fabricius, 1775), Otiorhynchus conspersus (Herbst, 1795) and Sitona lineellus (Bonsdorff, 1785) are confirmed or renewed by reference specimens. The overlooked record of Gymnetron aper Desbrochers.

We present an updated list of Ciidae for Switzerland, based on identifying and checking of specimens in museums and private collections as well as new field records and literature searches. Compared to the Catalogue of Palaearctic Coleoptera (Jelinek in Löbl & Smetana 2008) the number of species recorded in Switzerland increased from 26 to 41. First records for Switzerland are presented for Xylographus bostrichoides (Dufour. 1843), Orthocis linearis (J. R. Sahlberg. 1901) and Orthocis coluber (Abeille de Perrin. 1874a).

Secondo i criteri UICN il 43% degli Efemerotteri, il 40% dei Plecotteri e il 51% dei Tricotteri della Svizzera figurano nella Lista Rossa, il che corrisponde al 47% delle 499 specie dei tre gruppi di insetti acquatici con dati sufficienti; il 15% (71 specie) è inoltre potenzialmente minacciato. Le specie più minaccciate sono quelle dei fiumi delle basse quote (rettificazione degli alvei, modificazione della dinamica di deflusso, qualità dell’acqua) e in parte anche quelle dei laghi piccoli, degli stagni e dei ruscelli campestri (emissioni nocive, snaturazione).
