Estimated rates in mg/mL required to reduce oviposition by 50% (EC50, “effective concentration” for 50% reduction) for each acylsugar source.

Acylsugar sources include purified acylsugar extracts, S. pennellii LA1376 fractions, and a blend of fractions. The analyzed responses of B. tabaci (MEAM1) were ROSPF, the rates at which females changed oviposition sites relative to a control treatment; and REPF, the rates at which females oviposited eggs (aggregate number of eggs) relative to a control treatment, during non-choice leaflet oviposition bioassays. The analyzed response of F. occidentalis and F. fusca was the probability of oviposition to a treated synthetic membrane during choice bioassays.
