3.7.2.3

Measuring the efficacy of textile samples already treated for glove test (Figures

3.7 and 3.8)

This method has been suggested for repellant bioassays against Asian tiger mosquito

(Aedes albopictus): IR3535 applied on textile fabrics (A. Michaelakis et al. 2019). The

evaluation of sample repellence is done using the glove and a cut window where sam-

ples are positioned and inserted in a cage with 200 Aedes aegypti following the above-

mentioned procedure (Figure 3.8).

3.7.2.4

Evaluation of lotions of botanical-based repellents

This evaluation was carried out, during a 3-month activity as “visiting scientist” at

AMCD, Florida, USA, 2020, where many botanical repellent compounds were evaluated

against laboratory-reared Aedes aegypti L (Whitney A. Qualls, Rui-De Xue, Muhammad

Farooq, Steven T. Peper, Vindhya Aryaprema, Kai Blore, Richard Weaver, Dena Autry,

Asghar Talbalaghi, James Kenar, Steven C. Cermak, Junwei J. Zhu 2020) (Figure 3.9).

3.7.3

Measuring the efficacy of repellent by use of olfactometer

Verifying the presence of odors with repellent nature and measuring the efficacy or

persistency of a product separately is mandatory before the impregnation and incorporation

into a fabric . Olfactometer test serves to fulfill this task (Figure 3.10).
