Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) is a serious pest of corn in several American countries. It is mainly controlled with synthetic insecticides. The objectives of this study were to evaluate the effects of the natural products, neem oil and pyroligneous extract, and the synthetic insecticide, lufenuron, at 2.50mL water (0.25 %) on the mortality of 2-, 4- and 6-day-old caterpillars of S. frugiperda, and their selectivities against fourth instar larvae of Eriopis connnexa Germar (Coleoptera: Coccinellidae). Four- and 6-day-old S. frugiperda caterpillars showed higher mortality after exposure to neem oil (83.33 ± 0.83 and 89.58 ± 0.90 %, respectively) and lufenuron (95.83 ± 0.96 and 85.41 ± 0.83 %), compared to pyroligneous extract (68.75 ± 0.69 and 31.25 ± 0.31 %). The deleterious effect of pyroligneous extract was higher in 2- (83.33 ± 0.83 % mortality) and 4-day-old (68.75 ± 0.69 %) S. frugiperda caterpillars than in 6-day-old caterpillars (31.25 ± 0.31 %). Larval mortality of the predator E. connexa was lower with neem oil and pyroligneous extract (25.00 ± 0.33 %) than with lufenuron (91.66 ± 1.22 %). Neem oil is thus recommended for control of S. frugiperda because of its high toxicity, combined with its relatively low toxicity to larvae of the natural enemy E. connexa. |

Abstract: Mesocarp fiber (MF) and oil palm decanter cake (OPDC) are inexpensive substrates from oil palm refineries with potential to reduce fungal enzyme costs. This work demonstrated the producing enzymes method from mono- and co-cultures of micro- and macro-fungi cultured in MF or OPDC. Macrofungal species evaluated include Panus lecomtei, Trametes versicolor, Schizophyllum commune, Coprinus sp., Chrysosporium lucknowense, and Laetisaria arvalis. Secreted enzyme activities from individually cultured macrofungal strains were compared with Trichoderma reesei enzymes. Fungi co-culturing were evaluated in plates and submerged fermentation. Enzyme cocktail produced by co-culturing T. reesei and P. lecomtei exhibited higher laccase, peroxidases, hemicellulase and cellulase activities. Pretreated sugarcane bagasse (PSB) saccharification, with co-cultured enzyme cocktail, produced 12.3 g.L?1 of glucose, which was 44.7% higher when compared with T. reesei that produced 8.5 g.L?1. This work is the first to report co-culturing fungi to produce superior enzymes cocktail from OPDC that will benefit future lignocellulosic biorefinery. |
