Selected morphometrics of Heterorhabditis bacteriophora and seven species of Steinernema from in vivo culture were compared in relation to time of harvest. In addition, five Steinernema species were reared in vitro and their morphometrics were compared with those from in vivo culture. With in vivo culture, there was generally a negative linear relationship between body length of infective juven...

The citrus mealybug, Planococcus citri (Risso, 1813) (Hemiptera: Pseudococcidae) is one of the major pests Citrus orchards in Turkey. Management P. quite challenging due to its cryptic and polyphagous feeding behavior. In current study, control potential native entomopathogenic nematodes (EPNs) species (Heterorhabditis indica 216-H, H. bacteriophora FLH-4H, Steinernema carpocapsae E-76, S. felt...

Five bacterial strains were isolated from the hemocoel of the greater wax moth larvae (Galleria mellonella) infected with the entomopathogenic nematodes: Heterorhabditis bacteriophora HP88, Heterorhabditis indicus RM1 and Heterorhabditis sp (S1), Steinernema abbasi and Steinernema sp. (S II). Strains were identified as Photorhabdus luminescens HRM1, P. luminescens HS1, P. luminescens HP88, Xeno...

The potential for entomopathogenic nematodes to control ßies in cattle feedlots was determined by screening 40 strains representing 8 species of Heterorhabditis Poinar and 5 species of Steinernema Travassos for virulence toward 3rd-instar house ßies (maggots), Musca domestica L. None of the 22 strains of Heterorhabditis infecting maggots caused signiÞcant levels of mortality in a Þlter paper as...

The discovery of Meloidogyne mayaguensis is confirmed in Florida; this is the first report for the continental United States. Meloidogyne mayaguensis is a virulent species that can reproduce on host cultivars bred for nematode resistance. The perineal patterns of M. mayaguensis isolates from Florida show morphological variability and often are similar to M. incognita. Useful morphological chara...

insect immunity comprises behavioral, physical and innate immunity. in this study, innate immune response of the greater wax moth larvae, galleria mellonella against two species of entomopathogenic nematodes, heterorhabditis bacteriophora and steinernema feltiae,   as important biocontrol agents were studied. total haemocyte count in larvae injected with h. bacteriophora increased immediately. ...
