Abstract: Botanical insecticides based on azadirachtin and the entomopathogenic nematode Steinernema feltiae were evaluated for their control of the peach fruit fly, Bactrocera zonata. Laboratory bioassays determined the potential of combinations between the biological control agent S. feltiae and the botanical insecticides NSK, NeemAzal T 5%, Neemix 4.5% against 3rd instar larvae of B. zonata. Of 25 treatment combinations between azadirachtin from NSK extract and S. feltiae, 18 gave synergistic responses, 4 were additive, none antagonistic and 3 without any response. The same number of combinations with NeemAzal T 5% showed 19 synergistic responses, 1 additive, none antagonistic and 5 without any response. Combinations of Neemix 4.5% and S. feltiae showed 11 synergistic responses, 5 additive, 3 antagonistic and 6 without any response. The combined use of botanical insecticides based on azadirachtin, especially NSK extract and NeemAzal T 5%, with the entomopathogenic nematode S. feltiae may offer an integrated approach to increase the efficacy of control of the peach fruit fly, B. zonata, by entomopathogenic nematodes.
