The use of pesticides in agriculture boosts food production yields. However, pesticides are directly linked to declining pollinator populations, consequently impacting crop productivity. Assessing the effects of pesticides on pollinating bees is crucial for informing crop management strategies and public policies. This manuscript provides a dataset from the study that evaluated the toxicity of the active ingredients λ-cyhalothrin (insecticide) and fenpyroximate (acaricide) on the stingless bee species Nannotrigona testaceicornis (Apidae: Meliponini). The results include measurements of bee's weight, survival, ingestion rates, behavioural responses, and the bee behavioural stress index (BSI). This dataset can be further used for ecological risk assessments, determination of risk factors and quotients, and developing behavioural indices, models, and clustering analyses. Policymakers can use this dataset to support their decision-making processes.
