Efficiency of Heterorhabditis bacteriophora (Nematoda: Heterorhabditidae) on Anastrepha serpentina (Diptera: Tephritidae) larvae under laboratory conditions
Florida Entomologist 89 (4), 524-526
Abstract: The infectivity of the entomopathogenic nematode Heterorhabditis bacteriophora was tested on third instars of the tropical fruit fly, Anastrepha serpentina, under laboratory conditions. An LC50 was estimated at 36.0 ± 5.4 IJ /cm2 of sandy soil, adjusted to 15% humidity, with 5-cm-deep infectivity units. Significant amounts of nematodes are required to obtain satisfactory control levels, as shown by 3 x the LC50 value. This is the first report on the susceptibility of the tropical fruit fly larvae to H. bacteriophora. Potential of this nematode as a biological control agent of this pest should be corroborated under field conditions.
