Effects of low storage temperature on survival and infectivity of two Steinernema species (Nematoda : Steinernematidae)
Survival of two British steinernematids, one a strain of Steinemema feltiae (Filipjev) [ = S. bibionis (Bovien)], and the other an undescribed species designated Steinernema sp. (Nashes strain) was assessed after storage of infective juveniles in sterile sand at 5 "C and 15 "C and was measured by their motility (ability to be extracted by mini Whitehead trays). Infectivity after storage at the ...
متن کاملFactors influencing the infectivity of a Canadian isolate of Steinernema kraussei (Nematoda: Steinernematidae) at low temperature.
The effectiveness of Canadian isolate 76 of Steinernema kraussei, at 10 degrees C, in penetrating Galleria mellonella larvae (percentage parasitism and number of IJs developed to adult nematodes) was measured at different host densities (differing number of larvae and size of experimental arena) and for different durations of exposure. The greater the size of the inoculum of infective juvenile ...
متن کاملEffect of Soil Depth and Moisture on the Vertical Distribution of Steinernema riobrave (Nematoda: Steinernematidae).
The effect of soil moisture on the distribution of Steinernema riobrave in a sand column was determined. Larvae of Pectinophora gossypiella were used to detect S. riobrave infective juveniles (IJ) in each 2.5-cm section of 30-cm-long soil columns. Soil moisture was determined for each section and related to the numbers of nematodes recovered from infected insect baits. Infective juveniles of S....
متن کاملSteinernema akhursti sp. n. (Nematoda: Steinernematidae) from Yunnan, China.
A new species of entomopathogenic nematode, herein described as Steinernema akhursti sp. n., was recovered from soil samples collected from Yunnan Province, the People's Republic of China. Both morphological and molecular data show congruently that S. akhursti sp. n. belongs to the Steinernema feltiae group. It can be separated from all described Steinernema species by the combined morphologica...
متن کاملEffect of Soil Texture on the Distribution and Infectivity of Neoaplectana carpocapsae (Nematoda: Steinernematidae).
The vertical migration of N. carpocapsae infective juveniles applied to the soil surface or introduced 14 cm below the soil surface was studied in four different soil types (pure silica sand, coarse sandy loam, silty clay loam, and clay). The percentage of juveniles able to migrate and infect wax moth pupae placed in the soil decreased as the percentage of clay and silt increased. Most nematode...
