“…Hirose et al (2001) observed 45% reduction in spore germination of B. bassiana when mixed with neem oil at 2%. Therefore, the mixture of aqueous oil emulsion and spores of the pest-controlling entomopathogen, must be avoided.…”

“…The difference between the results reported in those studies and the results observed in this work may be due to the variability in the amount de triterpenoids and other compounds in neem seeds, which are used for the formulation of commercial products (Sidhu et al 2004), or to emulsifiers and stabilizers used in manufacturing. However, negative effects caused by emulsible neem oil, to the entomopathogen, are reported by Bajan et al (1998) and Hirose et al (2001).…”

“…For some authors, emulsible neem oil inhibts micelia growth (Bajan et al 1998, Hirose et al 2001 and the production and germination of spores of B. bassiana (Hirose et al 2001).

Neotropical Entomology 34(4): 601-606 (2005) ABSTRACT -The compatibility of a commercial formula of emulsible neem oil (Azadirachta indica A. Juss.) and of aqueous extracts of neem seeds and leaves with Beauveria bassiana (Bals.) Vuill. was evaluated in vitro. Three experiments were conducted to evaluate the effect of each product on the fungus vegetative growth and on conidia production and viability. The products were incorporated to a culture medium (BDA+E) and distributed into petri dishes, in the following concentrations: 0.15%; 1.5% and 15% (leaf aqueous extract), 1%; 2% and 4% (seed aqueous extract) and 0.5%; 1% and 1.5% (emulsible oil). Vegetative growth and conidia production were the basis for characterization of the aqueous extracts of seeds and leaves and of the emulsible oil, using the T classification model for compatibility of products. Seed and leaf extracts were less harmful to B. bassiana than the emulsible oil. Under the tested concentrations, the oil was not compatible with B. bassiana, inhibiting conidia vegetative growth significantly and decreasing production and viability of conidia, particularly at higher concentrations. Neem seed and leaf extracts were compatible with the entomopathogen in all concentrations. The seed extracts reduced conidia vegetative growth and production, but it did not affect the viability of spores. Leaf extract at 15% had a small negative impact on vegetative growth, and on production and viability of conidia, but it was still compatible with the fungus B. bassiana, according to the T model.

“…According to Hirose et al (2001), the use of chemicals which are incompatible with fungi can inhibit the development and reproduction of these microorganisms, thus affecting an effective biological control. This incompatibility has been reported by studies which have demonstrated the influence of chemicals on entomopathogenic fungus viability (Barci et al, 2009) although, in another study, the fungus and insecticide employees were considered compatible, allowing their joint use in controlling (Anhalt et al, 2010).…”

In vitro susceptibility of nematophagous fungi to antiparasitic drugs: interactions and implications for biological control

et al. 2016

View full text Add to dashboard Cite

The fast anthelmintic resistance development has shown a limited efficiency in the control of animal's endoparasitosis and has promoted research using alternative control methods. The use of chemicals in animal anthelmintic treatment, in association with nematophagous fungi used for biological control, is a strategy that has proven to be effective in reducing the nematode population density in farm animals. This study aims to verify the in vitro susceptibility of the nematophagous fungi Arthrobotrys oligospora, Duddingtonia flagrans and Paecilomyces lilacinus against the antiparasitic drugs albendazole, thiabendazole, ivermectin, levamisole and closantel by using the Minimum Inhibitory Concentration (MIC). MICs ranged between 4.0 and 0.031 µg/mL for albendazole, thiabendazole and ivermectin, between 0.937 and 0.117 µg/mL for levamisole, and between 0.625 and 0.034 µg/mL for closantel. The results showed that all antiparasitic drugs had an in vitro inhibitory effect on nematophagous fungi, which could compromise their action as agents of biological control. D. flagrans was the most susceptible species to all drugs.Keywords: nematophagous fungi, benzimidazoles, ivermectin, levamisole, closantel. Suscetibilidade in vitro de fungos nematófagos à antiparasitários: interações e implicações para o controle biológicoResumo O desenvolvimento rápido da resistência anti-helmíntica demonstrou a eficiência limitada no controle de endoparasitoses em animais, e promoveu a investigação em métodos de controles alternativos. O uso de produtos químicos no tratamento anti-helmíntico animal, em associação com fungos nematófagos utilizados para o controlo biológico, é uma estratégia que tem provado ser eficaz na redução da densidade da população de nematódeos em animais agrícolas. Este estudo teve como objetivo verificar a suscetibilidade in vitro dos fungos nematófagos Arthrobotrys oligospora, Duddingtonia flagrans e Paecilomyces lilacinus frente aos antiparasitários albendazol, tiabendazol, ivermectina, levamisol e closantel, usando a concentração inibitória mínima (MIC). Os MICs variaram entre 4,0 e 0,031 μg/mL para albendazol, tiabendazol e ivermectina, entre 0,937 e 0,117 μg/mL para o levamisol, e entre 0,625 e 0,034 μg/mL para closantel. Os resultados mostraram que todos os antiparasitários tiveram um efeito inibidor in vitro sobre os fungos nematófagos, o que poderia comprometer suas atividades como agentes de controle biológico. D. flagrans foi a espécie mais sensível a todas as drogas.Palavras-chave: fungos nematófagos, benzimidazóis, ivermectina, levamisol, closantel.
