In Brief:
The Invenesis tick larvae repellent assay evaluates both deterrent and fast toxicity effets of a treated surface with test compounds on larvae of hard ticks (Ixodidae).
Tick larvae are deposited in a circular arena where one quadrant of the surface is treated. Ticks are deposited in the non-treated area. After 1 minute, the distribution of ticks in the treated and untreated areas is measured for a duration of 2 minutes. Repellent effect is expressed in %. 100% means that ticks completely avoided the treated surface. Toxicity is measured in the same setup over a duration of 8 minutes and the mortality is expressed in % motility reduction between the beginning and the end of the 8 minutes.
