Larvicidal efficiency of the fungus Amanita muscaria (Agaricales, Amanitaceae) against Musca domestica (Diptera, Muscidae)

Abstract

ResumoAção larvicida do fungo Amanita muscaria (Agaricales, Amanitaceae) em Musca domestica (Diptera, Muscidae). Foi relatada a ação larvicida de duas formulações de Amanita muscaria em Musca domestica. Dois métodos de extração foram testados: extrato aquoso de basidioma desidratado e triturado (BDT), e extrato de basidioma fresco liquefeito em água (BFL). A mortalidade causada pelo extrato BDT variou de 14,67% a 100%. A eficácia do extrato BFL variou de 10,67 a 89,33%. A concentração letal média (CL 50 ) do extrato BDT foi de, aproximadamente, 1.931,02 ppm, enquanto que a CL 50 do extrato BFL foi em torno de 30%. As substâncias extraídas por esses métodos de extração não interferiram no período de desenvolvimento dos imaturos e não influenciaram no peso pupal dos indivíduos. Esses resultados mostram o potencial de extratos de A. muscaria para o controle de M. domestica.

Two methods of extraction were tested: an aqueous extract from dried, powdered basidiomes (DPB); and an extract from fresh basidiomes liquefied in water (FLB). The mortality caused by the DPB extract varied from 14.67% to 100%. The efficiency of the FLB extract varied from 10.67% to 89.33%. The mean lethal concentration (LC 50 ) of the DPB extract was approximately 1,931.02 ppm, whereas the LC 50 for the FLB extract was about 30%. The extracted substances from these methods did not interfere with the development period of immatures and did not influence pupal weight. These results show the potential of A. muscaria extracts for controlling M. domestica.

Larvicidal and Repellent Activity of Lagenaria Siceraria (Cucurbitaceae) Extracts Against the House Fly: Musca Domestica (Diptera: Muscidae)

“…Lagenaria siceraria belongs to family Cucurbitaceae is known to be eco-friendly and are not toxic to vertebrates. Moreover, it is clearly proved that crude or partially purified plant extracts are less expensive and highly efficacious for the control of Musca domestica rather than the purified compounds or extracts (Jang et al, 2002;Cavalcanti et al, 2004). However L. siceraria was used for the first time to control M. domestica.…”

“…The effect of tested L. siceraria leaves extracts on larval mortality of M. domestica was in a harmonious with earlier reports for using plant extracts against the larvae of M. domestica. The obtained results are agreed with Begum et al (2010) for the crude ethanolic leaves extracts of Calotropis procera and Anonna squamosal (LC 50 values were 282.5 and 550ppm), Begum et al, (2011) for ethanolic extracts of Calotropis procera (seeds) on 3 rd instar larvae of M. domestica (the 100.0% mortality was observed at 500ppm), Akhater et al (2012) for the fresh leaf of milk weed (Calotropise procera) juice against larvae of M. domestica, Sinthusiri et al (2013) for essential oils from Cinnamomum verum, Myristica fragrans and Syzygium aromaticum against M. domestica, Ogbalu et al (2014) for the aqueous leaf extract of tobacco (Nicotiana tabacum) on M. domestica Carapeto et al, (2017) for two formulations of Amanita muscaria against M. domestica with two methods of extraction, where the mean lethal concentration (LC 50 ) of aqueous extract from dried, powdered basidiomes (DPB) was approximately 1931.02ppm and the LC 50 for the fresh basidiomes liquefied in water (FLB) was about 30%. Also, similar results were recorded by Fouda et al (2017) for ethanolic, acetone and petroleum ether extracts of Lantana camara (leaves and stems) against 3 rd instar larvae of M. domestica, where petroleum ether extract from leaves and stems were more toxic than acetone and ethanolic one.…”
