^aCost for the T. chilonis and Bt was estimated based on cost of production and retail price of the insecticides at 2 July 2017
^bLocal purchase price of the cabbage was (US$ 0.23 kg⁻¹) on 5 October 2017
^cNet profit was calculated based on the only income of cabbage and the cost per hectare from different treatments
