Park, S.-C., Wi, A.J., & Kim, H.S. 1994 Response of Matsucoccus thunbergianae males to synthetic sex pheromone and its utilization for monitoring the spread of infestation.. Journal of Chemical Ecology 20(9): 2185-2196.
Notes: Attraction of (2E,4E,6R,10R)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one [1; 6R,10R)-matsuone] and its antipode [2; (6S,10S)-matsuone] to Matsucoccus thenbergianae males was studied in the laboratory and in the field. They showed stronger response to 1. In laboratory bioassays, the threshold concentrations for male attraction with 1 and 2 were 16 fg and 150 pg. respectively. In the field, during the first two days after traps were set, traps baited with 50 µg of 1 on rubber septa or filter paper rolls caught more males than control traps. Between the sixth day and the tenth day after traps were set, in a daily trap catch experiment, the traps with 50 µg of 1 on filter paper rolls caught more males than control traps on one day only, whereas those on rubber septa were always effective. The shape of the traps did not affect male catches. Males were caught on pheromone traps in locations where no scales were found by the customary detecting procedures.
