dc.description.abstractLeafminer (Liriomyza spp.) are polyphagous pests that attack a variety plants, making the population of this pest is hard to control in some areas. However the information about leafminer’s spesies that attack on Karo Regency and the level of the parasitization is very minimum. This research is aimed to find out about that information on tomato and potato plants. This research was conducted from September to December 2024 in Berastagi District, Simpang Empat District, and Merdeka District at an altitude of 1200-1500 masl.

On potato plants L. huidobrensis (63) and L. sativae (63).
