Originating in South America, Pea Leafminer (Liriomyza huidobrensis) (PLM) has been a pest of vegetable and ornamental crops in Southern Ontario for four years. Several common crops in the area have incurred extensive economic loss with few means of effective control. Host plant preferences of colony, greenhouse, and field PLM populations were observed under lab conditions among six previously reported crops. 25 mated male and female PLM <2 days old were confined within a cage containing celery, pea, cucumber, potato, Asian broccoli, and lettuce for 48 hours. Three leaves per plant were stained using a lactophenol-acid fuchsin solution. Preference was determined by quantitatively measuring eggs and stippling damage per cm2 using a dissecting microscope (25x magnification). Factors describing performance (developmental time, pupal weight, % emergence) of colony reared PLM were observed under lab conditions on six hosts.
