Absolute and Relative Activity of Microencapsulated Natural Essential Oils against the Larvae of Carpet BeetleAnthrenus flavipies(LeConte)

Abstract

This study focuses on finding natural ecofriendly alternatives to the existing commercial Anthrenus flavipies resist chemicals. Eucalyptus, lavender, and citronella microcapsules were explored as natural alternatives. Chemical contents of microcapsules and fragrance releasing property were tested using gas chromatography. Absolute (proofing) and relative (repellent) activities of microcapsule treated fabrics were tested against the larvae of carpet beetle Anthrenus flavipies (LeConte). Proofing activity test results revealed that natural essential oils act as a deterrent for Anthrenus flavipies, but give lesser protection compared to commercial chemical permethrin. Repellency test results also affirmed these findings and it was observed that Anthrenus flavipies prefers to eat untreated fabric compared to its treated counterpart.

Comfort Properties and Antimicrobial Activity of Cotton and Nylon/PU Knits Treated with Microcapsules Containing Sea Buckthorn Oil

“…Microencapsulation is a technology that entraps the core material (gas, solid particles, and fine droplets) into the wall material (polymer) [1], has been widely applied to textiles for a variety of purpose such as antimicrobial activity [2], active thermoregulation, UV protection, and fragrance release [3]. In textile fields, a variety of core material has been applied including natural bio-active oil like Eucalyptus, lavender, and citronella [4] and thermoregulatory paraffin [5]. Owing to their biofunctions such as antimicrobial activity, anti-inflammatory properties, and moisturizing, various natural oil has been attempted to be filled into microcapsules.…”
