Workers and nymphsc 0.21 0.11 November

aAmounts of norharmane in R. speratus were determined by single replicate analysis of 500 or 1000 termites by GC/MS. GC/MS analysis was separately conducted in May and November. Quantitative analysis of an external standard of 20 ppm norharmane in May and November had a margin of error of ~5%.
