“…The establishment of nematode species and isolates in H. longipennis varied between 3.77% (H. indica CK2) and 7.29% (S. lamjungense LMT5). Similar differences in penetration into other white grub species were observed amongst different other species (Koppenhöfer et al 2007) and varied from very low 1% (S. scarabaei to Cyclocephala borealis) to as high as 22% (S. scarabaei to Anomala orientalis).…”

Potential of Nepalese entomopathogenic nematodes as biocontrol agents against Holotrichia longipennis Blanch. (Coleoptera: Scarabaeidae)

Holotrichia longipennis Blanch. (Coleoptera: Scarabaeidae) is a serious pest of commercial crops in Siduwa, Dhankuta, Nepal. Seven indigenous isolates of entomopathogenic nematodes (Steinernema lamjungense LMT5, S. lamjungense SS4, S. everestense DKP4, S. abbasi CS1, S. sp. KL1, Heterorhabditis indica CK2 and H. indica CK6) were used in a series of bioassays against the insect. All isolates showed an increased dispersal in response to H. longipennis. Nematodes were more attracted towards third instar larvae than to second instars. Differences in penetration and multiplication in the insect were observed amongst the seven isolates. Steinernema lamjungense LMT5, S. everestense DKP4 and S. abbasi CS1 caused greater mortality than other isolates to different developmental stages. Pupae and second instar larvae were more susceptible than third instar larvae. Significant differences were observed in LT 50 values of the isolates against different stages of H. longipennis. Three isolates (S. lamjungense LMT5, S. everestense DKP4 and S. abbasi CS1) along with a commonly used insecticide (chlorpyrifos) were tested against this insect in pot and field experiments. In pot experiments using maize and cabbage as a host crop, S. lamjungense LMT5 and S. everestense DKP4 performed better than S. abbasi CS1 and yielded a mortality comparable with chlorpyrifos. Similar results were observed in field experiments 3 weeks after nematode application. These experiments overall suggest S. lamjungense LMT5 to be a promising biocontrol agent against H. longipennis followed by S. everestense DKP4 and S. abbasi CS1.

“…Insects reduce the probability of nematode infection by several actions: they obstruct their anus with a large amount of fecal material (scarab grubs), minimize their CO 2 output or release CO 2 in intermittent bursts that minimize the presence of chemical cues (lepidopterous pupae and scarab grubs), and generate impenetrable cocoons or soil cells before pupation that serve as physical barriers (many lepidopterans, scarabs, and weevils) (Hazir, Kaya, Stock, & Keskin, 2003). Heterorhabditid IJs have an anterior tooth that can be used to assist in penetrating directly through soft, thin cuticle (Bedding & Molyneux, 1983) and steinernematids have also been reported to penetrate through the soft cuticle (Koppenhöfer, Grewal, & Fuzy, 2007;Peters & Ehlers, 1994). Accordingly, a thick or hard cuticle also serves as a physical barrier to EPN infection.…”

“…and Photorhabdus spp., are lethal parasites of many insects. These nematodes are broadly used in biological plant protection programmes (Burnell and Stock 2000;Koppenhöfer et al 2007). One of the advantages of their use is that these nematodes are easy to culture and may be kept in vitro and in vivo (Lacey et al 2001).…”

The aim of this study was to determine the effect of different initial doses of the infective juveniles (IJs) (50 IJs, 200 IJs, 1000 IJs ) of Heterorhabditis megidis Poinar (Rhabditida: Heterorhabditidae) strain IsM15/09 on recovery, final yields and percent final yields in larvae Galleria mellonella ( L.). Percent recovery was not directly related to initial dose. Final yields also did not change with the initial dose. However, percent yields was highly negatively correlated with initial dose of nematodes and was the highest with the 50 IJs dose. Additional point of the study was to investigate whether the nematodes are able to produce progeny from one hermaphroditic individual. The results showed that the invasive larvae resumed growth and transformed into hermaphroditic individuals that reproduced without cross-fertilisation.
