EFFECTS OF MALE ACCESSORY GLAND SUBSTANCES ON FEMALE BEHAVIORS OF AEDES ALBOPICTUS(DIPTERA:CULICIDAE)

초록

The difference in the mating, host-seeking, and ovipositor behaviors of unmated and mated females resulted from the MAGs substances transferred to the female of Aedes albopictus were examined. There was a significant difference between the female injected with different equivalents of MAGs of A. albopictus from control with 100.0% of the mating rate, 05 gland equivalents with 0.0%, 1.0 gland equivalens with 3.3% and 2.0% gland equivalents with 3.3%, respectively, showed that MAGs of A. albopictus inhibited greatly the mating behavior of female adults. While only 2.2% of the mated females responded, 30.2%, a significantly larger percentage of the unmated females, engaged in host-seeking behavior. The effects of MAGs on the host-seeking behavior, 27.8% of the gravid females that were injected with saline responding compared to 7.0% of those injected with 0.5% gland equivalents responded. The difference in response between the two groups was highly significant. Thus, the MAGs specifically affected the host-seeking behavior of gravid females mosquitoes and appeared to account for the effect of mating in A.albopictus. The ovipositor rate from the female injected with 0.5 gland equivalent of MAGs was 42.2%, while that from control was just 15.7%. As the females injeced with 1.0 gland equivalent og MAGs showed 46.3%, those with 2.0 gland equivalent of MAGs was 49.4% oviposition rate. The induction og oviposition seems to be dependent on dosage of MAGs of A. albopictus.
