Abstract Background Outbreak of the fall armyworm Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) occurred in Mizoram, North-Eastern India. The infestation spread entire state covering a total area around 2840 hectares maize cultivated land. Entomopathogenic nematodes (EPNs) represent potential candidates for biological control S. . In study, susceptibility pest against 4 loca...

J. Econ. Entomol. 89(5): 1109-1115 (1996) ABSTRACT Entomopathogenic nematodes-Heterorhabditis bacteriophora Poinar (Oswego strain), Steinemema carpocapsae (Weiser) (NYOOI strain), Steinemema carpocapsae (25 strain), Steinemema feltiae Filipjev (=Neoaplectana carpocapsae Weiser) (369 strain), Steinemel1la feltiae (27 strain), and Steinemel1la riobravus Cabanillas and Poinar (355 strain)-were exa...

maceae) is a nematophagous fungus that has been shown to be effective against a wide spectrum of plantparasitic nematodes (Rumbos and Kiewnick, 2006). The commercial strain 251 (PL251) has recently received US registration as a biological nematicide under the trade name MeloCon WG, whereas it is undergoing registration procedure as BioAct WG in Europe (Kiewnick and Sikora, 2006). Entomopathog...

Abstract In some governorates of Egypt, the African migratory locust L. migratoria migratorioides is in a gregarious phase. Swarm development was successfully prevented by biological control agents. this work, two entomopathogenic nematode species, Steinernema sp. (SII)and Heterorhabditis bacteriophora (HP88) were investigated as natural enemies against fifth nymph and adult locusts at various ...

The effects of different application technologies were evaluated on the concentration, viability, and effi ciency of infective juveniles of the nematodes Heterorhabditis indica Poinar, Karunakar & David and Steinernema sp. (IBCB-n6) to control Spodoptera frugiperda Smith on corn plants. Two hundred and eighty infective juveniles of Steinernema sp. were required to kill 100% third-instar fall ar...
