Rearing
A field collected population of T. tabaci was maintained
in a laboratory rearing . Rearing units
consisted of a glass jar (0.5 l) that was covered by a fine
mesh cloth (105 mm) for ventilation. A piece of filter
paper was placed on the bottom of each glass jar as a
hiding place and pupation site for prepupae and pupae.
The insects were provided with fresh leek leaf pieces
(Allium porrum L.) for feeding and oviposition three
times a week.
