“…Immobilization and mortality effects have also been observed in Daphnia magna exposed to a B. thuringiensis-based insecticide, raising concerns on the potential lethal and sublethal effects such formulations may pose to non-target species at environmentally relevant concentrations. 10 Recently, Challa et al 30 demonstrated that both B. thuringiensis-and B. bassiana-based formulations were slightly to moderately toxic to honey bees. Sublethal effects on female Aedes aegypti fertility and wing length were shown after exposure to the entomopathogenic fungus Leptolegnia chapmanii, 84 similar effects may be expected with B. bassiana infection.…”

“…Furthermore, the increasing use of microbial insecticides has raised concerns regarding their ability to disseminate, survive and multiply in other environments where there is a risk of infection of non‐target species . In fact, deleterious effects of microbial insecticides on non‐target species have been reported and further ecotoxicological assays evaluating their potential impact on freshwater non‐target insects are needed. This evaluation should rely on not only acute toxicity tests, but also sublethal effects including sub‐organismal and immunological responses that can be altered by different natural and chemical insecticidal compounds .…”

BACKGROUND Commercial formulations based on Bacillus thuringiensis subs. kurstaki (Btk) and Beauveria bassiana (Bb) are commonly used microbial insecticides in Brazil and other tropical regions. However, and despite being considered environmentally friendly, their use generates concerns regarding possible adverse ecological effects in freshwater ecosystems. Here, we evaluate the effects of these bioinsecticides on the tropical aquatic dipteran Chironomus xanthus under laboratory conditions. RESULTS After laboratory exposures to these compounds 48‐h median lethal concentration (LC50) values of 1534 μg a.i./L for Btk and of 6.35 μg a.i./L for Bb were estimated. Chronic assays revealed different sublethal effects: Btk‐based bioinsecticide exposure reduced C. xanthus growth [lowest observed effect concentration (LOEC) was 126 μg a.i./L for head width], decreased emergence rate (LOEC = 8 μg a.i./L) and increased immunological response (LOEC = 50 μg a.i./L) measured as total hemocyte count in larvae hemolymph. Exposure to low concentrations of Bb‐based insecticide also reduced C. xanthus growth (LOEC = 0.07 μg a.i./L for larvae body length measurements), and emergence rate (LOEC = 0.28 μg a.i./L), despite no clear effects on the total hemocyte counts. CONCLUSION Our results suggest that low concentrations of Btk and Bb bioinsecticides are toxic to C. xanthus. Given their widespread use and occurrence in tropical freshwater systems, research is needed to evaluate the potential effects of these compounds concerning natural freshwater insect communities and ecosystem functioning. © 2019 Society of Chemical Industry

Enantiomeric effect of paclobutrazol on the microorganism composition during wine fermentation

et al. 2020

Pesticide residues in food can bring potential risks to human health and has been widely concerned in recent years. In the current study, the influence of paclobutrazol, which resided in raw material (grape) on wine fermentation process, were investigated. The degradation kinetic results indicated that the enantiomers of paclobutrazol not be degraded during 30 days of fermentation process. In order to achieve the fermented microorganism information of diversity, community composition, and function, the analysis of 16S rRNA and ITS sequencing were performed. Results demonstrated that the dominant microorganisms multiplied and the microbial diversity in the samples decreased as the fermentation process progresses. Furthermore, the paclobutrazol stimulated the growth of Pichia, which was observed during wine fermentation and which may have an underlying impact on the quality of the wine. The above results inferred that paclobutrazol residue could disturb the microbial community stability during wine fermentation, and the stable existence of paclobutrazol will cause potential risks to food safety and human health. In this work, we have successfully devised a method to investigate the influences of pesticide residues in raw materials during food processing and conclusions from this study could provide basis for dietary risk assessment.

“…Aparentemente, por não representar uma ameaça direta à sobrevivência das abelhas, seus esporos são disseminados em plantações por meio do uso de forrageiras de Bombus terrestris (L.) e Apis mellifera L. (Vandenberg, 1990;Meikle et al, 2008). Contudo, apesar da ausência de relatos quanto aos impactos diretos sobre as colônias, seus efeitos subletais podem ser observados nos indivíduos, como por exemplo, na diminuição da velocidade de forrageamento (Challa et al, 2019). Também podem provocar alterações do perfil cuticular (Csata et al, 2017), particularmente dos hidrocarbonetos que são abundantes na epicutícula dos insetos (Blomquist & Bagnères, 2010), e variações quantitativas e/ou qualitativas desses compostos orgânicos interferem no reconhecimento intra-e/ou interespecífico (van Zweden & d'Ettorre, 2010).…”
