Long-term field performance of a polyester-based long-lasting insecticidal mosquito net in rural Uganda.

ABSTRACT:

Background

In order to evaluate whether criteria for LLIN field performance (phase III) set by the WHO Pesticide Evaluation Scheme are met, first and second generations of one of these products, PermaNet, a polyester net using the coating technology were tested.

Methods

A randomized, double blinded study design was used comparing LLIN to conventionally treated nets and following LLIN for three years under regular household use in rural conditions. Primary outcome measures were deltamethrin residue and bioassay performance (60 minute knock-down and 24 hour mortality after a three minute exposure) using a strain of Anopheles gambiae s.s. sensitive to pyrethroid insecticides.

Results

Baseline concentration of deltamethrin was within targets for all net types but was rapi
