Abstract
In this study, the passage of spermatophores was examined between 1-day-old males mated in no-choice situations with females 0, 2, 4, or 6 days old and the converse for both the codling moth,
Cydia pomonella
(L.) (Lepidoptera: Tortricidae), and the obliquebanded leafroller,
Choristoneura rosaceana
(Harris). For
C. pomonella
, female age had no effect on the passage of spermatophores from males, and only 6-day-old female
C. rosaceana
had reduced spermatophore number. The ages of moths at the time of mating had a greater effect on males, with
C. pomonella
males older than 2 days showing significant reductions in the ability to successfully pass a spermatophore to 1-day-old females. For
C. rosaceana
, 2- and 6-day-old males were significantly less likely to pass a spermatophore, but reduced transfer from 4-day-old males did not reach statistical significance. Wind-tunnel assays were used to evaluate the ability of 1- or 4-day-old males to fly upwind and successfully contact a young calling female. Four-day-old males were more likely to initiate flight upwind, but were less efficient at finding and contacting the females than younger males. This study suggests that evaluation of multiple components of the mating process are required to understand the effect of age at the time of mating on population dynamics of these moths.
