摘 要：The present review article demonstrates laboratory and field evaluations of entomopathogenic nematodes(EPNs)against different developmental stages of fruit *** virulence of the EPNs differed clearly even on the same insect species and/or by the same nematode *** differences might be attributed to some reasons such as the method of treatment as well as the concentrations of the tested *** flies are among the most important insect pests infesting vegetables and fruits causing considerable losses in the yields *** laboratory studies,the tested nematodes proved to be highly virulent to larvae as percentage of mortality may reach 100%.As for treated pupae,at different ages,the results are variable and controversially;some studies revealed their moderate or high susceptibility to nematode infection and others indicated low susceptibility or resistance to *** adults,or those emerged from treated larvae or pupae,are also susceptible to *** semi-field and field trials,EPNs proved to be successful for reducing the populations of some fruit flies with up to 85%at concentrations not less than 100 infective juveniles(IJs)/cm^2 of ***,the field applications of commercial EPNs have been recommended to be 2.5-5 x 10^9 IJs/ha(25-50 IJs/cm^2 of soil).
