RNAi-Mediated Whitefly Resistance in Cassava: Bioassay and Gene Expression Results

Table 2 from a figshare document by Narayanan Narayanan, last updated May 2026, details results from transgenic cassava lines engineered for whitefly resistance. The dataset likely contains bioassay results showing up to 58% adult lethality within 7 days and 75-90% nymph lethality after 25 days, alongside gene downregulation data. It supports research into controlling the Bemisia tabaci whitefly, a vector for major cassava diseases in East Africa.

Use Cases

• Evaluating the insecticidal efficacy of different RNAi constructs based on reported adult and nymph mortality rates.
• Analyzing the correlation between target gene downregulation (up to 2.5-fold) and observed pest lethality.
• Modeling population dynamics for durable pest control in field conditions, as referenced in the study's discussion.

Strengths

• Specific quantitative results are reported, including 58% adult lethality and 75-90% nymph lethality.
• Research context is detailed, linking the data to a clear agricultural problem with over US$1.25 billion in annual losses.
• The data is associated with a defined methodology involving 15 RNAi constructs and 140 transgenic lines.

Limitations

• The dataset is very small at 18.9 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
