An in vitro experiment was carried out at college of horticulture, Venkataramannagudem, Dr. YSRHU to study toxic effects of Sweet flag Acorus calamus methanol extracts invasive pest Bondar’s nesting whitefly. The different concentrations of methonolic extracts were tested against Bondar nesting whitefly Paraleyrodes bondari adults by residual method. The results obtained from the experiment reveal that mortality percentage of P. bondari adults were 10%, 20%, 50%, 76.67%, 93.33% at 0.1%, 0.2%, 0.5%, 1% and 2% concentration respectively. 100% mortality was found in the methanol extract at 5% concentration with LC₅₀ value being 0.470% at 0.5% concentration.
