Abstract
Experimentos laboratoriais foram realizados para investigar a capacidade de isolados de fungos predadores das espécies Arthrobotrys musiformis (isolado 3), A. conoides (isolado A) e A. robusta (isolados B e E) de predar e matar larvas infectantes de Cooperia punctata. Dois grupos foram formados para o teste de cada isolado: grupo 1, fungos e larvas infectantes e grupo 2, larvas infectantes (controle). Houve diferença estatisticamente significativa (p<0,05) entre a atividade predatória do isolado E de A. robusta, quando comparado com todos os outros isolados de Arthrobotrys spp (isolados A, B e 3). Nenhuma diferença estatística (p>;0,05) foi encontrada entre o isolado E e o grupo controle. Isto pode indicar uma variação existente dentro de uma mesma espécie de fungo ou gênero quanto à predação de larvas infectantes de C. punctata.
Laboratory experiments were performed in order to investigate the capacity of isolates from the predacious fungi Arthrobotrys musiformis (isolate 3), A. conoides (isolate A) and A. robusta (isolates B and E) to trap and kill infective Cooperia punctata larvae. Two groups were formed for each isolate: group 1, fungi and infective larvae and group 2, infective larvae (control). There were statistical differences (p<0.05) between the predacious activity of one isolate of A. robusta (isolate E) when compared with the other isolates of Arthrobotrys spp (isolates A, B and 3). No statistical difference (p>0.05) was found between the isolate E and the control. This indicates that there can be an existing variability within a fungus species or genus concerning the predation of infective C. punctata larvae.
