Seasonal Changes in the Reproductive Condition of Female Black Cutworm Moths (Lepidoptera: Noctuidae)

Female black cutworms captured in blacklight traps during the 1978 and 1979 flight seasons in Iowa and Ohio were dissected and assigned to one of four reproductive classes. When females were categorized according to three flight periods (spring, summer, fall) the results showed that the spring and f...

Description
Summary:Female black cutworms captured in blacklight traps during the 1978 and 1979 flight seasons in Iowa and Ohio were dissected and assigned to one of four reproductive classes. When females were categorized according to three flight periods (spring, summer, fall) the results showed that the spring and fall flight periods were dominated by older mated females and unmated females, respectively. The summer flight periods were represented by large proportions of each of the four reproductive classes. The significance of these seasonal changes in the reproductive condition of female populations is discussed relative to pest management considerations. In Ohio (1979), 74% and 66% of the females of the spring flight and summer flight, respectively, had mated once.
