Abstract:
Studies were conducted on the combined use of a parasitoid wasp, Diglyphus begini, and an entomopathogenic nematode, Steinernema carpocapsae, for control of the leafminer, Liriomyza trifolii, on chrysanthemums. Several factors indicate that these two agents may be suitable for combined use: (1) leafminer larvae parasitized by the wasp are less susceptible to nematode infection, and (2) nematodes show equal orientation towards paralyzed/parasitized leafminer larvae and healthy leafminer larvae. However, interspecific interference and intraguild predation (IGP) between the agents were found. IGP may be minimized through proper timing of release of the control agents |
