Wilt Virus

The hydrogen ion concentration of the midguts of larval and adult Thrips tabaci and T. imaginis is between pH 5�0 and 5�6. The oxidation-reduction potential at these values is between + 0�184 and + 0�262 V. There is thus no difference between thrips that are vectors and those that are not vectors of the virus causing tomato spotted wilt. Furthermore, the pH and Eh conditions in the midgut of larval T. tabaci are unsuitable for long survival of the virus.

Gaseous Carbon Dioxide

The stimulus for the hatching of infective eggs of Ascaridia galli in vitro depended upon the concentration of undissociated carbonic acid plus dissolved gaseous carbon dioxide, the oxidation-reduction potential, and the hydrogen ion concentration. There was considerable overlap in the conditions which favoured the hatching of eggs of Ascaridia galli and Ascaris lumbricoides; both would be expected to hatch in the small intestine of a suitable species of host.
