Cryopreservation of Steinernema carpocapsae and Heterorhabditis bacteriophora.
A method for the cryopreservation of third-stage infective juveniles (IJ) of Steinernema carpocapsae and Heterorhabiditis bacteriophora was developed. Cryoprotection was achieved by incubating the nematodes in 22% glycerol (S. carpocapsae) or 14% glycerol (H. bacteriophora) for 24 hours, followed by 70% methanol at 0 C for 10 minutes. The viability of S. carpocapsae frozen in liquid nitrogen as...

The infectivity of four species of entomopathogenic nematodes, Steinernema carpocapsae (Weiser) [Breton strain], Steinernema riobrave Cabanillas, Poinar & Raulston [Weslaco strain], Heterorhabditis bacteriophora Poinar [HP88 strain], and Heterorhabditis indica Poinar, Karunakar & David [Coimbatore strain] was examined in the laboratory against two subterranean termites: Reticulitermes flavipes ...
متن کاملBIOLOGICAL CONTROL Application Technology for the Entomopathogenic Nematodes Heterorhabditis indica and Steinernema sp. (Rhabditida: Heterorhabditidae and Steinernematidae) to Control Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) in Corn1
The effects of different application technologies were evaluated on the concentration, viability, and effi ciency of infective juveniles of the nematodes Heterorhabditis indica Poinar, Karunakar & David and Steinernema sp. (IBCB-n6) to control Spodoptera frugiperda Smith on corn plants. Two hundred and eighty infective juveniles of Steinernema sp. were required to kill 100% third-instar fall ar...
متن کاملVirulence of entomopathogenic nematodes to pecan weevil larvae, Curculio caryae (Coleoptera: Curculionidae), in the laboratory.
The pecan weevil, Curculio caryae (Horn), is a key pest of pecans in the Southeast. Entomopathogenic nematodes have been shown to be pathogenic toward the larval stage of this pest. Before this research, only three species of nematodes had been tested against pecan weevil larvae. In this study, the virulence of the following nine species and 15 strains of nematodes toward fourth-instar pecan we...
متن کاملInteraction of the Koinobiont Parasitoid Microplitis rufiventris of the Cotton Leafworm, Spodoptera littoralis, with Two Entomopathogenic Rhabditids, Heterorhabditis bacteriophora and Steinernema carpocapsae
Entomopathogenic nematodes are generally considered beneficial organisms. However, they can affect beneficial insects such as parasitoids. The interaction between the entomopathogenic nematodes Heterorhabditis bacteriophora Poinar (Rhabditida: Heterorhabditidae) and Steinernema carpocapsae Weiser, and the parasitoid Microplitis rufiventris Kokujev (Hymenoptera: Braconidae) was investigated in t...
