Molecular Identification of Entomopathogenic Nematode Isolates from the Philippines and their Biological Control Potential Against Lepidopteran Pests of Corn

Heterorhabditis indica. The pathogenicity of these EPN was tested in Ostrinia furnacalis, Spodoptera litura, and Helicoverpa armigera larvae under laboratory conditions. All the EPN isolates were pathogenic to the lepidopteran species with, H. indica PBCB and S. abbasi MBLB exhibiting the highest virulence (88%–99.33% and 90%–100% mortality, respectively) at 48 hr post infection (HPI) and thus, further studies were done on these two EPN. The highest penetration rate at 48 HPI was observed in H. armigera

Virulence of Steinernema ceratophorum against different pest insects and their potential for in vivo and in vitro culture

instar larvae of S. litura, different instar larvae of the beet armyworm Spodoptera exigua Hubner (Lepidoptera: Noctuidae), the fall armyworm S. frugiperda, the European corn borer Ostrinia nubilalis Hubner (Lipidoptera: Cambidae) and the cotton bollworm Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) and their artificial diet were all purchased from Henan Jiyuan Baiyun Industry Co., Ltd. The larvae were reared on the artificial diet in growth chambers at 26 ± 1°C, 60 to 70% RH, and photoperiod
