The present study investigates the toxicological impact of deltamethrin, a widely used synthetic pyrethroid insecticide used in agriculture, specifically targeting the freshwater crab Barytelphusa cunicularis. The research delves into the insecticide’s mechanism of action and acute toxicity on the crab species. With the persistent presence of deltamethrin in soil disrupting microbial activity and water contamination posing threats to aquatic ecosystems. The investigation aimed to determine the lethal toxicity concentration of pesticide. The experiment reveals LC50 values at 24, 48, 72, and 96 hours, indicating concentrations of 0.0125, 0.0075, 0.006 and 0.0049 ppm respectively. The findings demonstrate a correlation between increased pesticide concentration and exposure period with a rise in percentage mortality. Adverse effects observed on B. cunicularis populations underscore the need to comprehend deltamethrins impact on non-target organisms. This research contributes significant insights into deltamethrins toxicology, offering valuable information for decision-making and in promoting sustainable pest management practices.

“…Piper aduncum L. is a Piperaceae that has been widely studied due to its chemical compounds with verified insecticidal activity against many insect orders. The toxicity of the essential oil of P. aduncum (EOPA) has been previously observed in several insect taxa, including Diptera (Misni et al 2011), Hymenoptera (Souto et al 2012), Coleoptera (Estrela et al 2006), Lepidoptera (Fazolin et al 2016) and Hemiptera (Turchen et al 2016). Furthermore, because of its synergistic activity in mixtures with other insecticides, EOPA has the potential to be employed as an alternative to synthetic insecticides (Fazolin et al 2016).…”

Researches on the use of essential oil of Piper aduncum L. (EOPA) as a synergist in stored grain pests are still incipient. This study aimed to determine the toxicity of deltamethrin and EOPA, as well as to study the effect of the binary mixture of EOPA + deltamethrin, on five Sitophilus zeamais Brazilian populations. The toxicity was investigated based on concentration-mortality data from deltamethrin and EOPA in thirteen S. zeamais populations. The standard susceptibility population of ¼ LC20 was used with the deltamethrin combinations to generate lethal concentrations capable of causing 50 and 95 % of mortality (LC50 and LC95). A binary mixture of EOPA x deltamethrin was also tested in five S. zeamais populations to detect the synergistic effect with the deltamethrin. The concentration-mortality curves were generated, and the residual toxicity values after 24 h of exposure ranged 0.003-0.08 µL cm-2 for deltamethrin, 0.04-2.038 µL cm-2 for EOPA and 0.0016-0.014 µL cm-2 for the binary mixture. The S. zeamais populations showed an uneven toxicity in response to the deltamethrin. The Jacarezinho (Paraná state) population showed resistance, with toxicity ratios for LC50 increasing by 3.06 and 4.13 times, when compared to susceptible populations, for EOPA and deltamethrin, respectively. The Barbacena (Minas Gerais state) population was considered as the susceptibility standard in the EOPA toxicity bioassays. The binary mixture suppressed the resistance mechanism of the tested S. zeamais populations due to the synergistic action of the bioinsecticide with the deltamethrin.
