Exploiting entomopathogenic nematode neurobiology to improve bioinsecticide formulations
Entomopathogenic nematodes (EPNs) are soil dwelling organisms that target and kill insects. They have sophisticated chemosensory apparatus, with which they perceive host associated cues to locate them. Once a suitable host is located, they employ a diverse range of host finding behaviours to …

Entomopathogenic nematode interactions with white grubs from forest and sugarcane plantations
… Such alternatives can include the use of entomopathogenic nematodes, EPNs. A review of the available literature revealed that EPNs can potentially provide a higher percentage control of white grubs, when compared to chemical insecticides. However, this control efficacy is characterized by …

Factors influencing the outcome of male-male encounters in the entomopathogenic nematode Steinernema spp.
… for development and reproduction of the nematodes. About three Steinernema generations can develop within one insect cadaver leading to the production of thousands of IJs. Steinernema longicaudum is the first nematode for which intraspecific male-male fighting behaviour was observed …

Development of biotools for vineyard-associated pest and disease control based on entomopathogenic nematode symbiotic bacteria
… In this context, symbiotic bacteria of entomopathogenic nematodes, specifically Xenorhabdus spp. and Photorhabdus spp., emerge as potential biocontrol agents due to their ability to produce bioactive compounds with insecticidal and antifungal properties. We hypothesized that these …

Non chemical alternatives for pest management: Entomopathogenic nematodes and UV-C light
… viability of rearing and storing four species of entomopathogenic nematode (EPN), Steinernema feltiae, Steinernema carpocapsae, Heterorhabditis bacteriophora, Heterorhabditis indica; and, 2) the efficacy of UV-C radiation applied, pre-transport, as a preventative disease control strategy against …

Competition and co-existence of Photorhabdus temperata subspecies temperata and Photorhabdus temperata subspecies cinerea, symbionts of Heterorhabditis downesi
… was to explore the relationship between the entomopathogenic nematode Heterorhabditis downesi and its two symbionts, Photorhabdus temperata subsp. temperata and P. temperata subsp. cinerea, and the relationship (co-existence and competition) between the two symbionts, which co occur on Bull …

Efficacy of Entomopathogenic Nematodes and Entomopathogenic Fungi against Masked Chafer White Grubs, Cyclocephala spp. (Coleoptera: Scarabaeidae)
Entomopathogenic nematodes (EPN) (Heterorhabditis bacteriophora and H. megidis) and entomopathogenic fungi (EPF) (Metarhizium anisopliae and Beauveria bassiana) were evaluated for efficacy against masked chafer white grub, Cyclocephala spp., under laboratory and greenhouse conditions, as well as …

Characteristics of biological control agents and their antagonism against rice pathogens and pests
… significant yield loss such as rice root-knot nematodes, bacterial leaf blight, and brown planthopper. Currently, pesticide use is the dominant practice for pest and disease management in Asian rice farming. The use of beneficial microbial agents for the control of pathogens and pests is a …

Biodiversità dei nematodi entomopatogeni in Sicilia: caratterizzazione molecolare, biologia e batteri simbionti
… in corso, riguardanti la complessa simbiosi nematode-batterio-insetto. Infine, sono stati acquisiti alcuni dati preliminari relativi ai batteri simbionti. Questi sono stati isolati e identificati fenotipicamente su piastre selettive, sia cromogeniche che antimicrobiche, e conservati in …
