Oogenesis in the codling moth, Cydia pomonella, and the role of juvenile hormones (JHs) were addressed. Rudimentary ovarian structures were recognisable in day 3-4 pupae, when haemolymph JH was still undetectable by coupled gas chromatography-mass spectrometry in the selected ion mode (GC-MS/ SIM).
## Abstract In vitro catabolism of juvenile hormone (JH) in haemolymph of adult female __Cydia pomonella__ was ascribed mainly to juvenile hormone esterase (JHE) activity. No significant differences were noted between virgin and mated females 0–96 h post‐emergence. Changes in JHE activity did not a
