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...
متن کاملThe influence of habitat quality on the foraging strategies of the entomopathogenic nematodes Steinernema carpocapsae and Heterorhabditis megidis.
Entomopathogenic nematodes (EPN) are soil-transmitted parasites and their foraging strategies are believed to range from 'ambush' to 'cruise' foragers. However, research on their behaviour has not considered the natural habitat of these nematodes. We hypothesized that EPN behaviour would be influenced by soil habitat quality and tested this hypothesis using 2 EPN species Steinernema carpocapsae...
متن کاملEffects of Fertilizers on Suppression of Black Cutworm (Agrotis ipsilon) Damage with Steinernema carpocapsae.
The ability of Steinernema carpocapsae to reduce damage to seedling corn by the black cutworm, Agrotis ipsilon, in soil amended with three fertilizers (fresh cow manure, composted manure, and urea) was determined. Total nitrogen was standardized among the fertilizers at 280 kg/ha and 560 kg/ha. Black cutworm damage was assessed by the percentage of cut corn plants in small field plots. Relative...
متن کاملCharacterization of a nucleopolyhedrovirus from the black cutworm, agrotis ipsilon (Lepidoptera: noctuidae)
The black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), is a serious localized pest of vegetable and field crops. We have characterized a newly discovered baculovirus, the Agrotis ipsilon multicapsid nucleopolyhedrovirus (AgipMNPV), that was isolated from A. ipsilon in Illinois. Restriction enzyme fragment profiles of AgipMNPV DNA were distinct from those of previously described...
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...
