Trichogramma populations were collected from sugarcane fields from four districts of Punjab. Important taxonomic characters such as body length, head length, head width, female antennae, fore wings, hind wings, male antennae and genitalia were studied and a morphometric analysis was performed. Descriptive analysis of ratios of characters (flagellar width/length, club width/length, fore wing length/width, genital capsule length/width) was also undertaken. Results revealed that females were bigger than males, and head was wider than long. Despite slight variations in size, all specimens were found to belong to T. chilonis.
