Nematodes that parasitize insects are known as entomopathogenic nematodes (EPNs). Molecular identification and genotyping of entomopathogenic nematodes are prerequisites for their proper classification, biodiversity studies, and their potential use in biological control programs. In the present study, a strain of entomopathogenic nematodes was isolated from the cultivated lands in Meerut region...

A greater knowledge of the morphology and the development of the infective third larval stage of Neoaplectana bibionis Bovien, 1937, a parasite of arthropods, makes it possible to recognise the second larval stage and present a description of all the developmental stages in the life cycle of the species. Four larval stages can be recognised. L1 hatches from the egg. In a suitable host, when the...

Abstract The soil-dwelling nematode Steinernema feltiae is found across a wide range of environmental conditions. We asked if its only bacterial symbiont, Xenorhabdus bovienii , shows intraspecific variability in thermal range, which may affect effectiveness S. against host insects. isolated X. from six different natural locations with mean annual temperatures and two laboratory cultures. estim...

Entomopathogenic nematodes (EPNs) (Rhabditida: Heterorhabditidae and Steinernematidae) are effective biocontrol agents for many insect pests generally stored a period of time prior to their use in the laboratory or field. However, unfavorable storage conditions have great impact on survival infectivity EPNs. This study was conducted determine optimum infective juveniles (IJs) four native EPN sp...

A new species of entomopathogenic nematode (EPN) named Steinernema balochiense n. sp. belonging to the family Steinernematidae was isolated from Psidium guajava L., rhizophere soil samples of Balochistan, Pakistan. This new species belongs to the carpocapsae group. The new species can be separated from other described species by morphological and morphometrics characteristics as well as DNA seq...

Entomopathogenic nematodes (EPNs) from the Heterorhabditidae and Steinernematidae families are well-known biocontrol agents against numerous insect pests. The infective juveniles (IJs) are naturally occurring in the soil and their success in locating and penetrating the host will be affected by extrinsic/intrinsic factors that modulate their foraging behavior. Characterizing key traits in the i...
