aIndividual 1- to 2-d-old intact virgin female moths (or in the case of hemolymph, samples of four females) were extracted during the last hour of photophase or the 6th hour of scotophase, respectively. The titer of each polyene (mean ± SD) was determined by GC-MS in selected ion monitoring mode using the base peak (m/z 79) for quantification versus 3Z,6Z,9Z-21:H as internal standard. Student’s t-tests showed no significant differences at the 5% level between photophase and scotophase extracted polyenes in the pheromone gland or whole abdominal tissue
bAbdomen = the whole abdomen with the pheromone gland removed, homogenized and extracted
cAbdominal cuticle = the abdominal cuticle with the pheromone gland, hemolymph, fat body, and other tissues removed
dHemolymph = the mixture of hemolymph and saline extracted from the abdomen, after injection of 10 µl Weever’s saline per female
