The accessory glands of male mosquitoes may produce substances that are transferred to females during mating and alter female physiology and behavior. This study was carried out to examine that the nutritional states of Aedes togoi affect the production of male accessory gland substances (MAGs) and the effects of MAGs on the mating and oviposition behaviors of female mosquitoes. The total protein content of MAGs from starved 3-day-old males (0.057 $mu extrm{g}$/gland) was significantly lower than that from sugar-fed males (0.091 $mu extrm{g}$/gland), There is a significant difference between the females injected with different equivalents of MAGs of Ae. togoi from control with 78.81％ of the mating rate,0.2 gland equivalents with 2.8.83％, 0.5 with 3.64％, 1.0 with 5.45％, and 2.0 with 2.75％, respectively. On the other hand, there is a significant difference between the females injected with different equivalents of MAGs of Ae. togoi from control with 55.17% of the oviposition rate, 0.2 gland equivalents with 88.00%, 0.5 with 85.71％, 1.0 with 88.46%, and 2.0 with 87.50％, respectively, The results obtained represent that the male accessory gland substances of Ae. togoi modulated the mating and oviposition behaviors of female mosquitoes.
