An electron microscopic investigation was carried out on citrus fruits and leaves collected during a survey in Pakistan. Thread‐like particles of citrus tristeza virus (CTV) were ascertained in phloem tissues of the columclla, whereas the bacterium associated with greening was detected in sieve tubes of the columella and in leaf midribs of trees showing typical yellow vein, fruit maiformation an decline. CTV was also confirmed by ELISA tests.
