Structure-activity studies revealed that the antiserum is specific to the N-terminal of DrmSP. This ELISA was used for the detection of DrmSP-like immunoreactivity in the reproductive tissues of male Helicoverpa armigera moths at femtomole levels. Two positive immunoreactive peaks were found in HPLC purified extracts of male accessory glands. The immunoreactive peak, which contained a higher amount of immunoreactivity, was also found to be pheromonostatic in PBAN-injected decapitated females as well as in intact female moths during their peak pheromone production. Lower levels of DrmSP-like immunoreactivity were found in younger males (1-2 day-old) when compared to older males (3-7 day-old). |
