One common question asked by greenhouse producers is associated with the effectiveness of systemic insecticides against the western flower thrips, Frankliniella occidentalis. Western flower thrips (WFT) are the most important insect pest of horticultural greenhouse-grown crops worldwide. In order to develop controls, it is essential to understand the feeding behavior of these pests.
WFT have piercing-sucking mouthparts, but they do not feed exclusively in the phloem sieve tubes. Instead, they feed within the mesophyll and epidermal cells of leaf tissues. More specifically, they feed on plants by inserting their tubular stylets into cells and withdrawing the cellular contents. This feeding behavior may inhibit the effectiveness of systemic insecticides against WFT; however, this is dependent on whether they are feeding on leaves or flowers. In addition, the anthophilic (inhabiting flowers) nature of WFT limits their exposure to systemic insecticides for several reasons:
The active ingredient is not readily transported into flower tissues (petals and sepals).
The concentration of active ingredient that is translocated into flower parts may not be sufficient to directly kill the thrips.
The active ingredient of a systemic insecticide may degrade faster in flower parts and differences in the transpiration rates between flowers and leaves may result in flowers being less efficient sinks for the active ingredient of systemic insecticides.
Systemic insecticides may not provide fast knockdown to prevent thrips damage to flowers when abundant populations are present.
All of these factors, however, may depend on the systemic insecticide and the associated water solubility, because systemic insecticides with greater water solubility may accumulate in flower parts at concentrations sufficient to kill WFT.
