Uso de extrato de nim no controle de acaríase por Myobia musculi Schranck (Acari: Miobidae) e Myocoptes musculinus Koch (Acari: Listrophoridae) em camundongos (Mus musculus var. albina L.)

Abstract

Neotropical Entomology 35(2): 269-272 (2006) Use of Neem Extract in the Control of Acariasis by Myobia musculi Schranck (Acari: Miobidae) andMyocoptes musculinus Koch (Acari: Listrophoridae) in mice (Mus musculus var. albina L.)ABSTRACT -The objective of this work was to evaluate the acaricide action of neem extract formulated as a pomatum in the treatment of acariasis in mice (Mus musculus var. albina L.) naturally infected by Myobia musculi Schranck and Myocoptes musculinus Koch. Twenty parasitized animals were chosen and distributed in four groups: control (vaseline), 5%, 10% and 20% of neem. The animals were treated at 48h intervals and maintained in cages with food and water ad libitum and accompanied daily for 24 days. There was a decrease in the mean number of mites recovered after 96h with 5% of neem when compared to de others concentrations (P < 0.05). From 120h on, the concentrations of 10% and 20% were also efficient and differed statistically from the control group (P < 0.05 and P < 0.01; respectively). From 168h on, the animals treated with neem concentrations of 10% and 20% showed significant results (P < 0.01). The animals exhibit signs of hair recuperation and the mites were not observed anymore. After 216h, the hair was completely recovered and the animals remained free of the infestation in the concentrations of 10% and 20%. The neem pomatum showed acaricide action in the concentrations of 10% and 20% for mice and when used as a topical remedy, had good phlogistic and cicatrizing activity and showed no side effects.

The use of an extract ofHypericum perforatumandAzadirachta indicain advanced diabetic foot: an unexpected outcome

“…Neem oil has shown to have cicatrising,14 bacteriostatic15 and anti-inflammatory properties. Its anti-inflammatory activity seems to be due to the presence of a limonoid (epoxyazadiradione) showing its effects on several inflammation markers of the macrophage migration inhibitory factors family 16…”

In vitro acaricidal activity of neem (Azadirachta indica) seed extracts with known azadirachtin concentrations against Rhipicephalus microplus

“…The indiscriminate use of insecticides has led to the rapid development of tick resistance, so control is currently hindered by the small number of effective molecules available in the market (Jonsson and Piper, 2007). The use of extracts from various plants is being studied because they are potentially less toxic to the animals and are safer for the environment (Santos et al, 2006;Albuquerque et al, 2007), although in vitro acute toxicities of neem-containing pesticides have been observed in experiments using hybridoma and oyster cells (Goktepe and Plhak, 2003).…”

Ação de extrato e óleo de nim no controle de Rhipicephalus (Boophilus) microplus (Canestrini, 1887) (Acari: Ixodidae) em laboratório

“…O princípio ativo azadirachtina, contido no nim, pode tornar-se importante no controle de pragas, pois tem largo espectro de ação, é compatível com outras formas de manejo, não tem ação fitotóxica, é praticamente atóxica ao homem e não agride o meio ambiente (MARTINEZ, 2002). Extratos dessa planta foram utilizados para o controle de algumas espécies de carrapatos como Hyalomma anatolicum excavatum Koch (Acarina: Ixodidae), Amblyomma americanum L. (Acarina: Ixodidae) e Dermacentor variabilis Say (Acarina: Ixodidae) (ABDEL-SHAFY; ZAYED, 2002;SANTOS et al, 2006).…”
