About this title

Synopsis

Excerpt from Insecticidal Properties of Some Plants Growing in Puerto Rico

Results are given Of laboratory screening tests Of up to 9 different parts Of 48 species Of plants in 23 families. Three or more local eco nomic representatives Of 4 orders were used as test insects. One or more parts Of 22 species Of plants in 13 families Showed moderate to high toxicity, and all tested parts Of 26 species in 15 families were inert or weakly toxic. Six out Of 11 species of Fabaceae, the largest family tested, and 1 out Of 4 species Of Clusiaceae, the next largest, were found to be toxic. Systematic position, or the fact that a given plant was poisonous to other animals or was a common weed rarely attacked by insects, was not a positive indication of insecticidal properties.
