Interspecific mating between Aedes albopictus males and Ae. aegypti females was detected in the field using mark-release-recapture techniques. By 3 days after the release of virgin Ae. aegypti females into a field site containing only Ae. albopictus, 100% of the captured females were inseminated. Laboratory investigations indicated that male Ae. albopictus were very proficient at inseminating Ae. aegypti females and that Ae. aegypti males rarely inseminated Ae. albopictus females, especially if Ae. aegypti females were available. Most of the Ae. aegypti females inseminated by Ae. albopictus males contained only small amounts of dead sperm in their spermathecae, while inseminated females from the converse interspecific mating and from intraspecific matings contained only large amounts of live sperm. The results are discussed in relation to the decline in Ae. aegypti densities observed since the introduction of Ae. albopictus into the southern USA.
利用标记释放再捕获技术在野外检测到白纹伊蚊雄蚊与埃及伊蚊雌蚊之间的种间交配。将未交配的埃及伊蚊雌蚊释放到仅含有白纹伊蚊的野外地点后3天，100%被捕获的雌蚊已受精。实验室研究表明，白纹伊蚊雄蚊在使埃及伊蚊雌蚊受精方面非常熟练，而埃及伊蚊雄蚊很少使白纹伊蚊雌蚊受精，尤其是在有埃及伊蚊雌蚊可供交配的情况下。大多数被白纹伊蚊雄蚊受精的埃及伊蚊雌蚊的受精囊内仅含有少量死精子，而来自相反种间交配和种内交配的受精雌蚊的受精囊内仅含有大量活精子。结合自白纹伊蚊引入美国南部以来观察到的埃及伊蚊密度下降情况对这些结果进行了讨论。
