<i>Lucilia cuprina</i> is a vector of important diseases in humans and animals that causes myiasis in sheep, leading to enormous damage to the sheep sector. Chemical products are used to control these flies; however, there are reports of resistance in addition to these products causing toxicity to the environment, humans, and animals, so alternative controls have been studied to reduce these impacts. <i>Pleurotus</i> spp. are basidiomycete fungi and present bioactive compounds with medicinal properties. Due to the potential use of fungi to control Diptera, this study aimed to verify the activity of <i>Pleurotus florida, P. ostreatus</i>, and <i>P. djamor</i> in the control of larvae and adults of <i>L. cuprina</i>, as well as the effects of aqueous extracts of the fungi <i>P. ostreatus, P. djamor</i>, and <i>P. florida</i> on larvae and adults of <i>L. cuprina</i>. The aqueous extract from <i>P. florida</i> was the only one that showed larvicidal activity against <i>L. cuprina</i>, with a half-maximal effective concentration of 11.42 mg/mL. In the test with adult stages, 30 insects were used for each solution concentration, sprinkled with 1 mL of the solution. All aqueous extracts showed adulticidal activity at all concentrations, <i>P. ostreatus</i> showing the best results, with adult mortality ranging from 75.86 to 100%. Our results demonstrated an important larvicidal effect of <i>P. florida</i> and an adulticidal effect of all AE, with emphasis on <i>P. ostreatus</i>.

Parasitic diseases are seen as indicators of a country's socioeconomic development, constituting a major public health problem as they cause direct health problems related to the lack of piped water, no sewage system, and lack of orientation. Contamination by the geohelminth Ancylostoma spp, causes the Cutaneous larva migrans (CLM), also known as "sandworms", presenting skin lesions of linear and serpiginous character. The aim of this study was to evaluate the in vitro larvicidal potential of guaco extracts (Mikania glomerata SPRENGEL) at different concentrations on A. caninum larvae. Obtained results showed the larvicidal effect of the M. glomerata extract starting from a treatment of 10mg/ml of guaco extracts (p<0.01). The larvicidal activity was best demonstrated in the 25 mg/ml treatment, in which a decrease of 13.30% of L3 was observed compared to the control group, and in the 50 mg/ml treatment (61.66%) reduction of L3. By means of the results, the applicability of the plant extracts used is suggested in A. caninum larvae control. In addition, more research is suggested to assess their employability in different extract forms, new concentrations, and in vivo studies, in order to ensure further clarification on the agents responsible for the observed effects, degree of efficacy and toxicity, and research continuity regarding the use concentration of the plant M. glomerata SPRENGEL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
