Identification of the Sex Pheromone of the Macadamia Felted Coccid, Acanthococcus Ironsidei (Hemiptera: Eriococcidae).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The macadamia felted coccid, Acanthococcus ironsidei (Williams), was recently discovered in South Africa. The insect has the potential to become a serious pest in South Africa’s macadamia industry and some areas in the Mpumalanga Province are already reporting damage due to A. ironsidei. The sex pheromone of A. ironsidei could provide a valuable monitoring tool for the pest, but has not been identified previously. In this study, the sex pheromone for A. ironsidei was identified as a 4:1 blend of racemic lavandulyl acetate and lavandulyl isobutyrate. The pheromone compounds were isolated from samples taken from plant material infested with adult virgin female scale insects. The compound identities were verified by mass spectral comparison and chromatographic retention indexes that were compared to synthetic compounds. The biological activity of these compounds was confirmed through field trials. This is the first report that confirms lavandulyl isobutyrate as a pheromone compound of a scale insect. Synthetic sex pheromones can now be used to enhance monitoring traps and could potentially be used for mass trapping and mating disruption of the pest.
