lemons, grapefruits, trifoliates [Poncirus trifoliata ], tangelos and
other related species (such as C. taiwanica ) were evaluated for
resistance to citrus leafminer (P. citrella ) under field conditions at

lime (Sweet lime), 1 of lemon (Galgal), 4 of grapefruits (Davis, Marsh
Prolific, Redblush and Star Ruby), 6 of trifoliates (Carrizo,
Citrumelo, Pomeroy, Rubidoux, Sacaton Citrumelo and Savage) and 1 of
related species (Sadaphal) were found to be least susceptible to
leafminer, while 3 cultivars of mandarin (Italian mandarin, Kondanarum
and Willow Leaf), 1 of lime (Kagzi lime), 1 of lemon (Jullundhiri
Khatti) and 2 of related species (Box orange and Karna Khatta) were
