AB  - The South American tomato leaf miner,<em> Phthorimaea absoluta</em> (Meyrick) (Lepidoptera: Gelechiidae) is an invasive pest which has been causing havoc both in greenhouse and open field. The study was conducted in mid-hill region of Himachal Pradesh during summer of 2022 and 2023 to record the seasonal abundance of the pest under field conditions. The per cent leaf and fruit infestation varied from 2.38 to 32.68 and 1.49 to 12.33 during 2022 and 3.70 to 29.71 and 1.30 to 9.09 during 2023, respectively. The number of mines, leaf infestation (%) and fruit infestation (%) had a significant positive correlation with relative humidity and minimum temperature. Adult trap catch showed a negative non-significant correlation with rainfall. Based on the results it is inferred that, monitoring and pest management interventions should be initiated in the early growth period of the crop to avoid build-up of the pest.
