Multigeneration toxicity of imidacloprid and thiacloprid to Folsomia candida

Multigeneration toxicity of imidacloprid and thiacloprid to Folsomia candida

In a recent study, we showed that the springtail Folsomia candida was quite sensitive the neonicotinoid insecticides imidacloprid and thiacloprid. This study aimed at determining the toxicity of both compounds to F. candida following exposure over three generations, in natural LUFA 2.2 standard soil. In the first generation, imidacloprid was more toxic than thiacloprid, with LC50s of 0.44 and 9...

Comparative toxicity of imidacloprid and thiacloprid to different species of soil invertebrates

Neonicotinoid insecticides have come under increasing scrutiny for their impact on non-target organisms, especially pollinators. The current scientific literature is mainly focused on the impact of these insecticides on pollinators and some aquatic insects, leaving a knowledge gap concerning soil invertebrates. This study aimed at filling this gap, by determining the toxicity of imidacloprid an...

Effect of pre-acclimation to sub lethal dose and combination of cold stress on tolerance of Folsomia candida to thiacloprid

QSAR development and bioavailability determination: the toxicity of chloroanilines to the soil dwelling springtail Folsomia candida.

Quantitative structure-activity relationships (QSARs) are an established tool in environmental risk assessment and a valuable alternative to the exhaustive use of test animals under REACH. In this study a QSAR was developed for the toxicity of a series of six chloroanilines to the soil-dwelling collembolan Folsomia candida in standardized natural LUFA2.2 soil. Toxicity endpoints incorporated in...

ECOTOXICITY ELEMENTS TOXICITY TO TERRESTRIAL ORGANISMS Soil invertebrates: Folsomia candida, Aporrectodea caliginosa

Remarks: Neat Na-LAS was 16.1 % (w/w) active C11.6 LAS in an aqueous solution, average molecular weight = 342 g/mol; Ca-LAS was > 99 % active C11.6 LAS (crystalline), average molecular weight = 674 g/mol (Ca is bivalent and therefore, each Ca atom has 2 LAS molecules); Mg-LAS 94 % active C11.6 LAS (crystalline), average molecular weight = 658 g/mol (Mg is bivalent and therefore, each Mg atom ha...
