Outline of Final Research Achievements

Our recent studies showed that female of Japanese mealybug, the pest of Japanese persimmon, have an ability to lay the largest number of eggs in a few days after emergence when they are usually mating.
On the other hand, if they remain unmated under the condition of mating disruption, the number of the eggs in their 28 days after the emergence when they can effuse the largest amount of sex pheromone, lay only half as many eggs as they do at their peak. Unmated females can live for a few months and 60% of them can lay eggs although the number of eggs per female was a few percent of that at their peak.
