Limiting opportunities for cheating stabilizes virulence in insect parasitic nematodes
Shapiro-Ilan D. and B. Raymond

Recommended by Thomas Sappington and Ruth Arabelle Hufbauer
Application of kin theory to long-standing problem in nematode production for biocontrol

Much research effort has been extended toward developing systems for managing soil inhabiting insect pests of crops with entomopathogenic nematodes as biocontrol agents. Although small plot or laboratory experiments may suggest a particular insect pest is vulnerable to management in this way, it is often difficult to scale-up nematode production for application at the field- and farm scale to make such a tactic viable. Part of the problem is that entomopathogenic nematode strains must be propaga...
