Field Performance of Entomopathogenic Nematodes against the Larvae of Zabrus spp. Clairville, 1806 (Coleoptera: Carabidae)

The ground beetles, Zabrus spp. Clairville, 1806 (Coleoptera: Carabidae) is one of the major pests wheat plants across world, and control this pest a challenging issue. In present study, potential two local entomopathogenic nematode (EPN) species [Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: Heterorhabditidae) Steinernema feltiae Filipjev, 1934 Steinernematidae)] against larvae was evaluated with trials under field conditions in 2015. EPNs were applied at concentration 1 x 106 IJs m-2 to soil surface mid-April number alive assessed 14 days after treatment (AT). addition, spp.-damaged counted establish efficacy on short (14 AT) long term (6 months AT). reduced by least 50% as compared treatments both trials. Altgough there remarkable decrease which applied, did not produce significant effect. Present findings indicate that tested have good for sustainable management
