Abstract
In no-choice experiments, the addition of sucrose to a diet of water had no effect on oviposition rate whether or not pollen was also present. However, the addition of 1% or 5% tannic acid to a diet of water decreased the oviposition rate by 68% and 86% respectively when pollen was also present. A novel design of U-tube cage allowed thrips to choose between two oviposition and feeding substrates in the presence of pollen. When thrips were offered a choice between 5% tannic acid solution and water, 88% fewer eggs were laid in the tannic acid. However, the total number of eggs laid per U-tube was not significantly different from in control U-tubes with water as the only substrate. It is concluded that tannin acts as a feeding deterrent and/or oviposition deterrent rather than as a toxin.
