Imidacloprid (IMI) belongs to the group of first generation neonicotinoids, known for their toxic effects non-target invertebrate species. Neonicotinoids have a specific mode action that mimics acetylcholine, impairing cholinergic neurotransmission, ultimately affecting survival organisms. This research aimed determine commercial formulation based on IMI survival, and life traits parameters larvae parental (P) F1 generations insect Chironomus xanthus. C. xanthus is bioindicator species...
Understanding the interplay among organophosphorus flame-retardants (OPFRs), microplastics, and freshwater organisms is crucial for unravelling dynamics within environments foreseeing potential impacts of organic pollutants plastic contamination. For that purpose, present research assessed exposure impact 10 mg L–1 flame-retardant alumin-ium diethylphosphinate (ALPI), μg mg–1liver microplastics polyurethane (PU), combina-tion ALPI PU on planarian Girardia tigrina....

Thiamethoxam (TMX) is a systemic neonicotinoid that acts as partial agonist of the nicotinic acetylcholine receptors (nAChRs). However, target species have shown resistance to formulations based on such neonicotinoids, which can also be expected for non-target insects. This research aimed study effects formulation TMX [Cruiser® 350 FS (CRZ)] life traits Chironomus xanthus filial generation (F1) and compare it with parental (P). Environmentally relevant concentrations CRZ significantly...
Neonicotinoid pesticides are one of the most commercialized groups worldwide. Their application in agriculture aims to control pests through a systemic mode action which is not specific target species. Our study aimed evaluate effects insecticide Actara® [active ingredient thiamethoxam (TMX)] on non-target species, Girardia tigrina. Therefore, acute and sublethal endpoints, such as mortality, feeding activity, locomotion behavioral biomarkers were assessed. exerted low toxicity towards...
Clothianidin (CLO) is an insecticide belonging to the second-generation class of neonicotinoids. In this study, we evaluated how CLO affects survival and complete life cycle tropical insect Chironomus xanthus, a non-target species, considering Parental (P) Filial (F1) generations. We found 48 h-lethal concentration (LC50) 3.78 µg/L. The lowest observed effect concentrations (LOECs) were: i) for body growth head capsule width in P generation = 47.3 ng/L CLO; ii) F1 larvae 80 36.4 CLO,...
Neonicotinoids are highly consumed pesticides, such as the insecticide Cruiser®/CRZ® (Thiamethoxam/TMX). They exhibit effects on non-target organisms and for these their slow degradation becomes a potential problem. Advanced oxidative processes (AOPs), photo-Fenton, chemically transform organic contaminants, forming byproducts with unknown toxicity. The were tested using planarian Girardia tigrina exposed to CRZ formulation, resulting after process. Damage was assessed by acute (LC 50...
Térmitas e formigas são agentes bióticos com alto nível de diversificação, indicando degradação do solo deficiência nutricional mesmo. Com os danos causados por eles, no em plantas eucalipto, faz-se necessário o controle dessas pragas, maneira que, para sucesso da aplicação manejo integrado a avaliação populacional desses indivíduos é fundamental, sendo imprescindível saber como eles se distribuem campo. Dessa forma, objetivou-se investigar dinâmica distribuição espacial ninhos termitas uma...
Background: The active secondary metabolites of various Kalanchoe species are promising for controlling insects and other agricultural pests. Objective: This study aimed to evaluate the mortality immune responses leafcutter ant Atta sexdens (L.) after treatment with ×laetivirens (Desc.) aqueous extract. effects on an aquatic organism used as a bioindicator, Chironomus xanthus (Rempel), were also evaluated. Methods: Different K. concentrations prepared by dilution in honey assess toxicity...
A necromassa encontrada nos ecossistemas realizam a manutenção do estoque de carbono. Seguindo esta orientação quantificação torna-se um atributo valioso para manejo florestal eficiente. O estudo teve como objetivos quantificar lenhosa caída e suspensa sobre o solo, peso carbono em área plano nativas subsidio ao mesmo. amostragem adotada utiliza método da fixa, foi conduzida através instalação uma circular com raio 10 metros (314 m2). Foram medidas 27 parcelas distribuídas sistematicamente,...
