Genetic Variability among Strains of the Entomopathogenic Nematode Steinernema feltiae.
A systematic program of genetic improvement was initiated by assessing the phenotypic variation of Steinernema feltiae strains for two traits assumed to limit efficacy: ultraviolet tolerance and host-finding ability. All of the strains assayed showed both low ultraviolet tolerance and poor host-finding ability, indicating that the likelihood of improving these traits through more extensive popu...
متن کاملIce-Active Substances from the Infective Juveniles of the Freeze Tolerant Entomopathogenic Nematode, Steinernema feltiae
Steinernema feltiae is a moderately freezing tolerant nematode, that can withstand intracellular ice formation. We investigated recrystallization inhibition, thermal hysteresis and ice nucleation activities in the infective juveniles of S. feltiae. Both the splat cooling assay and optical recrystallometry indicate the presence of ice active substances that inhibit recrystallization in the nemat...
متن کاملIntracellular Freezing in the Infective Juveniles of Steinernema feltiae: An Entomopathogenic Nematode
Taking advantage of their optical transparency, we clearly observed the third stage infective juveniles (IJs) of Steinernema feltiae freezing under a cryo-stage microscope. The IJs froze when the water surrounding them froze at -2°C and below. However, they avoid inoculative freezing at -1°C, suggesting cryoprotective dehydration. Freezing was evident as a sudden darkening and cessation of IJs'...
متن کاملNon-symbiotic association of Citrobacter freundii and Staphylococcus succinus with the entomopathogenic nematode Steinernema feltiae
نماتودهای خاکزی متعلق به خانواده Steinernematidae (Nematoda: Rhabditida) پارازیت های اجباری و کشنده حشرات بوده که معمولا تحت عنوان نماتودهای بیمارگر حشرات (Entomopathogenic nematodes) EPNs، از آنها نام برده می شود. این گروه از نماتودها به طور طبیعی با باکتری های جنس Xenorhabdus رابطه همزیستی داشته و نماتود مرحله سوم آلوده کننده یا Infective Juvenile، این باکتری ها را در یک وزیکول اختصاصی در ر...
متن کاملDevelopmental temperature effects on five geographic isolates of the entomopathogenic nematode Steinernema feltiae (Nematoda: Steinernematidae).
The development of five geographic isolates of Steinernema feltiae at 5, 8, 10, 15, 20, 25, and 28 degrees C in wax moth, Galleria mellonella, larvae was examined. The isolates were from Mediterranean (Sinop from Turkey, SN from France, and Monterey from California), subtropical (Rafaela from Argentina), and tropical (MG-14 from Hawaii) regions. All isolates caused 100% mortality of wax moth la...
