Alfalfa weevil

Entomopathogenic nematodes for the biological control of alfalfa weevil, Hypera postica by Ganpati Jagdale

Heterorhabditis indica and Steinernema carpocapsae for controlling alfalfa weevil Application of Heterorhabditis indica and S. carpocapase at the rate 1 billion nematodes per hectare can reduce 72 and 50% population of alfalfa weevil, Hypera postica grubs, respectively.  Another entomopathogenic nematode, Steinemema thermophillum was also effective in killing H. postica grubs (Shah et al., 2011).
