Heterorhabditis bacteriophora-infective stage juveniles (IJs) used in different distribution patterns
|
EPN-infected greater wax moth larvae over time
|
Mean values were less than one but differed significantly until 20 weeks after adding EPNs
|
The values indicate a more uniform distribution than a random one (New Jersey/USA)

|
Natural Steinernema feltiae and S. affine populations in grassland
|
IJs grouped to 4 groups of different physiological ages
|
The values were in the range 1.27–1.45, group II was the most aggregated stage
|
All values showed clumped distribution patterns (Merelbeke/Belgium)

Spiridonov et al. (2007)
|
H. bacteriophora or S. carpocapsae-infected greater wax moth larvae used within 24 h of starting IJ exit to planted fields and grassy plots
|
IJs of H. bacteriophora and S. carpocapsae recovered from greater wax moth larvae baits used after the cadavers
|
Mean values range < 1 to > 2. They differed between nematode species in bait traps and between control methods at 48 h and 16 days after placing the cadavers, respectively
|
Distribution patterns after dispersing from a grassy border plots into the adjacent cultivated field plots were more clumped for H. bacteriophora than for S. carpocapsae (Ohio/USA)
