Summary

The Department of Agriculture (DOA), as the NPPO of Thailand, has received a report confirming the presence of the tomato leaf miner (Phthorimaea absoluta) from samples collected from tomato orchards in Chiang Mai Province in March 2019. Since then, DOA has undertaken a specific survey for P. absoluta in line with ISPM No. 6 (Surveillance) on tomatoes and other host plants in the family Solanaceae.

The survey had been conducted from July 2019 to September 2023 in 77 provinces throughout Thailand. Pheromone traps for P. absoluta were installed on 334 plots with a total area of 1,415 rai (95 plots of tomatoes, total area 613 rai and 239 plots of other crops, total area 802 rai) as well as at plant quarantine stations along the border (area 6.25 rai = 1 hectare).

The results showed that P. absoluta was detected in tomato and potato orchards in only 8 provinces (Mae Hong Son, Chiang Mai, Tak, Loei, Nong Khai, Bueng Kan, Nakhon Phanom and Phetchabun). DOA has developed control programs for P. absoluta by using several methods. Integrated pest management was applied by using both chemical insecticides and biological insecticides. Furthermore, P. absoluta has been continuously monitored by utilizing a network of cooperation among regional agencies such as regional offices of the Department of Agricultural Extension (DOAE), regional offices of the DOA, plant quarantine stations along the borders, etc. The monitoring has been performed with the aim to early detect P. absoluta so that eradication could be promptly done in infested areas and to limit its spread in the country.
