“…Studies have confirmed the P. lilacinus ovicidal activity against several helminth species (Olivares-Bernabeu & Ló pez-Llorca, 2002;Santiago et al, 2006). Araú jo et al (1995) and Basualdo et al (2000) reported high in vitro activity of P. lilacinus on eggs of Toxocara canis.…”

The ovicidal activity of Paecilomyces lilacinus was evaluated on Moniezia sp. eggs. Eggs of Moniezia sp. were incubated on plates with 2% agar-water inoculated with grown fungal isolates and a control treatment without fungus. After 5, 10 and 15 days post-inoculation, the eggs were removed and classified according to the following parameters: effect type 1, lytic effect without morphological damage to eggshells; effect type 2, lytic effect with morphological change in embryos and eggshells; and effect type 3, lytic effect with morphological change in embryos and eggshells, with hyphal penetration and internal colonization of eggs. Paecilomyces lilacinus showed percentages for ovicidal activity (P < 0.01), mainly type 3 effect, of 19, 20 and 23% on eggs of Moniezia sp., after 5, 10 and 15 days post-inoculation, respectively. Therefore P. lilacinus can be considered as a potential biological control agent for this cestode.

“…There is a product based on the fungus Purpureocillium lilacinum (Thom) Luangsa‐ard, Houbraken, Hywel‐Jones & Samson (= Paecilomyces lilacinus (Thom) Samson), which is commercially registered in Brazil. This fungus is characterized as an egg parasite (Dunn, Sayre, Carrell, & Wergin, ), and its efficiency in controlling Meloidogyne spp., which exhibit aggregate oviposition, has already been confirmed (Kiewnick, Neumann, Sikora, & Frey, ; Kiewnick & Sikora, ; Lamovšek, Urek, & Trdan, ; Santiago et al., ). However, P. brachyurus lays single eggs, a fact that may compromise the efficiency of the product.…”

The aim of the current study was to assess the activity of Purpureocillium lilacinum and Trichoderma harzianum fungi, either alone or in combination, and the use of a bioactivator to control Pratylenchus brachyurus in soya bean crops. Thus, two experiments were conducted in a greenhouse, and two were conducted in naturally infested fields. Both fungi were efficient in controlling the nematode when they were applied alone, whereas the combination of the two did not improve nematode control. However, the addition of a bioactivator (moss) to the combination of fungi (P. lilacinum + T. harzianum + moss) generally promoted better control of the nematode in the greenhouse, with a reduction in the total abundance of the nematode ranging from 57.1% to 73.75%, and under field conditions, with a reduction ranging from 55.5% to 72.0%. The same treatment increased yield in both field experiments, but the treatment with T. harzianum promoted greater gains in productivity, varying from 11.79% to 20.85%.

RESUMOCom a finalidade de diminuir as perdas causadas pelos nematóides do gênero Meloidogyne (Goeldi, 1887) na cultura do cafeeiro, dentre as diversas medidas de manejo, o controle biológico com o fungo Paecilomyces lilacinus (Thom., 1910) ABSTRACTIn order to reduce the losses caused by nematodes of the genus Meloidogyne (Goeldi, 1887) in coffee plantation, among several management measures, biological control with the fungus Paecilomyces lilacinus (Thom., 1910) Samson, 1974 stands out as an advantageous alternative of control, from the ecological or economy points of view. Thus, the objective of this work was to evaluate ten isolates of Paecilomyces lilacinus in the control of Meloidogyne paranaensis in coffee trees (Coffea arabica L.) cv. Icatú, in greenhouse conditions. In the first experiment, the coffee seedlings were transplanted to substrate where tomato plants were previously cultivated, for M. paranaensis multiplication. The soil was mixed with 50 g rice colonized with ten isolates of P. lilacinus. In the second experiment, coffee seedlings were transplanted to substrate (1 sand: 1 dirt) with 50 g rice colonized with the isolates of P. lilacinus. Then, the seedlings were inoculated with suspension of ±5000 eggs of M. paranaensis. In the two experiments, a new application was made with 50 g of the isolates after fifteen days. The design was completely randomized with twelve treatments and ten replicates. After 90 they days were evaluated. The isolated of P. lilacinus did not affect the diameter of the coffee stalk. In the first experiment, the isolates Pae 22, 24, and 28 promoted the growth of the seedlings, all of the isolates reduced the population of eggs in the root system, and the isolates Pae 3 and 12 reduced the population of J2 of M. paranaensis in the soil. In the second experiment, the isolates Pae 3, 10, 12, and 13 favored the growth of the plants but reduced the weight of the fresh roots, all of the isolates reduced the population of J2 in the soil, and the isolates Pae 3, 10, 13, 18, 22, and 24 reduced the malformations caused by M. paranaensis roots.
