Integrated pest management (IPM) has been recognized as the best solution to minimize the adverse effects of insecticides applied to farmland. This study aims to evaluate the effectiveness of the trapping crop system (TCS) and arbuscular mycorrhizae (AM) against leaf miner, an important horticultural pest throughout the world including on shallot crops in Indonesia. In a factorial research design, cucumbers use in TCS was planted in three different pattern: one rows in the center; TC1, two rows in the middle; TC2, and one-row surroundings the shallot; TC3, while AM consists of two levels that are with (M1) and without AM (M2) application. The variables measured were: population and infestation of leaf miners as well as parasitism at the main and trap crops. The results showed that the leaf miners population was significantly reduced by TCS application but had no relation with AM. The leaf miners population decreased by about 40.1% at the TCS compared with the controls. However, the combination of TCS and AM reduced the leaf miner infestation by about 47.5% where TC3M1 showed the best treatment against leaf miners. Increasing of the parasitoids population and parasitism at the shallot and cucumbers as trap crops as well as the shallot resistance against leaf miner may explain the compatibility of TCS and MA to manage the pest. The study denoted the importance of IPM against shallot leaf miners to support sustainable farming system.
