Twelve species of fungi growing on the Sabouraud medium in darkness and illumination in an incubator, were tested to find out their ability to emit the ultra-weak biochemiluminescence. Using a sensitive photon-counling device, it was possible to measure biochemiluminescence intensity during ten days of cultures growth. <i>Boletus edulis, Pestalotia funerea</i> and <i>Microsporum gypseum</i> displayed biochemiluminescence, while <i>Aspergillus nidulans, A. quadrilineatus, Beauveria bassiana, Macrophoma candollei, Mucor lausanensis, Paecilomyces farinosus, Penicillium</i> sp., <i>Trichoderma lignorum</i> and <i>Tricholoma equestre</i> failed to do it. Illumination put down biochemiluminescence and stimulated colour formation in both mycelia and in the medium.

Conidial Viability

Twenty four strains of the entomopathogenic fungi (Hyphomycetes) Beauveria bassiana, Metarrhizium anisopliae, Nomuraea rileyi, Paecilomyces farinosus, P. fumosoroseus and P. lilacinus, maintained in the culture collection of Embrapa-Centro Nacional de Pesquisa de Recursos Genéticos e Biotecnologia (Cenargen) and preserved by lyophilization and in liquid nitrogen, had their conidial viability assessed. Germination rates of 16- to 84-month-old cultures stored in liquid nitrogen decreased, on average, less than 13.3%. For 29- to 49-month-old cultures preserved by lyophilization, the viability loss ranged, on average, from 28.6 to 94.5%. The results demonstrated the efficiency of the tested methods, especially liquid nitrogen, in preserving the viability of entomopathogenic fungi.

The spectrum and occurrence of entomopathogenic fungi in litter beech forest. meadow soil and arable soil were evaluated using an "insect bait method". Soil and litter samples taken in autumn and spring from each stand were baited with <i>G. mellonella</i> larvae at 22°C. Six species of entomopathogenic fungi infected these larvae. In the litter <i>Beauveria bassiana</i> was the dominant species. Besides <i>B. bassiana</i>, 23% of <i>G. mellonella</i> larvae were infected by <i>Paecilomyces farinosus</i> in autumn. In the forest soil the dominant entomopathogenic fungus was not found. In this stand the number of infected larvae was the lowest. <i>Metarhizium anisopliae</i> was the dominant species in the meadow soil in both sampling periods. In the soil taken from a rye field<i> P. fumosoroseus</i> and <i>B. bassiana</i> infected <i>G. mellonella</i> larvae almost to the same degree. It was established that <i>B. bassiana</i> and <i>M. anisopliae</i> infected more <i>G. mellonella</i> larvae in spring than in autumn. In the case of <i>P. farinosus</i> and <i>P. fumosoroseus</i> an opposite tendency was observed.

A associação de extratos de origem vegetal com fungos entomopatogênicos pode aumentar a eficiência do controle biológico de pragas, reduzir custos e impactos ambientais. No presente trabalho, avaliou-se, através da concentração inibitória mínima, o efeito do óleo de nim (NIM-I-GO) sobre o crescimento, esporulação e viabilidade de Metarhizium anisopliae, Beauveria bassiana e Paecilomyces farinosus. Utilizou-se o meio BDA, contendo diferentes concentrações de óleo de nim (C1: 5% de óleo de nim, e sucessivamente concentrações iguais a ½ da concentração anterior, até C11: 0,0048% de óleo de nim). O óleo de nim reduziu o crescimento de colônias de B. bassiana e P. farinosus, que não diferiram significativamente do controle apenas na concentração C11, mas para M. anisopliae o mesmo efeito foi observado com 0,039% de óleo de nim (C8). A esporulação também foi significativamente reduzida pelo óleo de nim, exceto na concentração C11 para B. bassiana; contudo, não se verificou efeito do óleo na viabilidade de esporos dos fungos.

As formigas cortadeiras atacam diversas culturas agrícolas, pastagens e os reflorestamentos, atuando sobre muitas espécies vegetais. O presente trabalho teve por objetivo avaliar a patogenicidade dos fungos Beauveria bassiana (isolados AM 9 e JAB 06), Metarhizium anisopliae (isolados E 9 e AL) e Paecilomyces farinosus (isolados CG 189 e CG 195) a soldados de Atta sexdens sexdens, em condições de laboratório. Após a coleta em formigueiro isento de produtos fitossanitários, exemplares de soldados foram cuidadosamente separados em grupos de oito indivíduos e, a seguir, banhados em suspensões contendo 1,0 x 10(6), 1,0 x 10(7), 1,0 x 10(8) e 1,0 x 10(9) conídios/mL de cada isolado. Em seguida, cada grupo de formigas foi transferido para unidades de câmara úmida e mantido, sem alimentação, a 27 ± 1 ºC. A mortalidade foi verificada diariamente. Os três fungos se mostraram eficientes patógenos, pois provocaram alta mortalidade, matando mais que 80% dos soldados nos quatro primeiros dias após a inoculação. Os melhores isolados foram JAB 06 e AL, na concentração de 1,0 x 10(9) con./mL. Os isolados JAB 06, AL, CG 195 apresentaram maior capacidade de esporular nos cadáveres das formigas e os tempos letais decresceram com o aumento da concentração de conídios usada.

The samples of soil for experiment were taken from arable field and meadow. Larvae of <i>Laspeyresia pomonella</i> and <i>Plodia interpuactella</i> were used as an "insect bait" for isolation of entomopathogenic fungi from the soil. <i>Beauveria bassiana, Metarhizium anisopliae, Paecilomyces farinosus</i> and <i>P. fumosoroseus</i> were isolated from both kinds of soil.
