Compatibility of entomopathogenic nematodes with chemical pesticides

Recently, Radova (2011) reported that the chemical pesticide fenpyroximate showed no adverse effect on virulence of entomopathogenic nematode Heterorhabditis bacteriophora but it reduced the virulence of Steinernema feltiae against the insect called mealworm Tenebrio molitor under laboratory conditions.

Entomopatogenic nematodes are compatible with many insecticides

Recently, Negrisoli et al. (2010) demonstrated that entomopathogenic nematodes including Heterorhabditis indica, Steinernema carpocapsae and Steinernema glaseri were found to be compatible with many insecticides including chlorpyrifos, deltamethrin, lufenuron, deltramethrin + triazophos, diflubenzuron, gamacyhalothrin, lambdacyhalothrin, spinosad, cypermethrin, triflumuron, and permethrin under laboratory conditions.

Biological control of fall army worm (Spodoptera frugiperda) an insect pest of corn

Recently, Andalo, et al. (2010) demonstrated that the entomopathogenic nematodes Steinernema arenarium and Heterorhabditis sp. can kill over 80% larvae of fall army worm, Spodoptera frugiperda under both laboratory and greenhouse condition. Read following paper for the information on the effect of entomopathogenic nematodes on fall army worm.

Control of fall armyworm, Spodoptera frugiperda with entomopathogenic nematodes

The fall armyworm, Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) is considered as an economically important pest of corn in Brazil.  Entomopathogenic nematodes have a potential to include as biological control agents in the integrated pest management (IPM) programs to control the armyworm.  Recently, Negrisoli et al. (2010a) reported that several insecticides including Chlorpyrifos, Deltamethrin, Llufenuron, Deltramethrin + Triazophos, Diflubenzuron, Gamacyhalothrin, Lambdacyhalothrin, Spinosad, Chlorpyrifos, Cypermethrin, Triflumuron and Permethrin were compatible with the three species of entomopathogenic nematodes including Heterorhabditis indica, Steinernema carpocapsae and Steinernema glaseri under laboratory conditions.  Furthermore, it has been also reported that the efficacy of an entomopathogenic nematode, H. indica was enhanced against fall armyworm, Spodoptera frugiperda when mixed with an insecticide, Lufenuron (Negrisoli et al., 2010b).
