Steinernema glaseri(Sgib strain) could be used as biocontrol agent for A. hetaoheilarvae because of the better anti-desiccation ability and pathogenicity.Sgib strain showed high infectivity to the cocooned larvae as well as the mature larval A. hetaohei.Sgib strain had the optimum infecting effect with 100 IJs per larva at 24 ℃ and still maintained high pathogenicity after spraying into the field for 96 h.The results suggested that some potential for Sgib strain from Steinernematidae as one tool in controlling A.hetaoheilarvae, which is the main fruit-boring pest of walnut in China
