Efficiency of heterorhabditis bacteriophora (Nematoda: heterorhabditidae) on Anastrepha serpentina (Diptera: tephritidae) larvae under laboratory conditions
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 3χ 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.
