“…A number of field trials have been conducted to evaluate the efficacy of EPNs for suppressing other wood-boring insects such as Metamasius hemipterus (L.) (Coleoptera: Curculionidae) (Giblin-Davis et al, 1996), Synanthedon spp. (Lepidoptera: Sesiidae) (Bedding and Miller, 1981;Miller and Bedding, 1982;Deseö et al, 1986;Kaya and Brown, 1986;Cossentine et al, 1990;Nachtigall and Dickler, 1992) or root-boring such as Delia radicum (L.)
