Aedes aegypti and Aedes albopictus, two important vectors of the dengue and chikungunya viruses to humans, often come in contact in their invasive ranges. In these circumstances, a number of factors are thought to influence their population dynamics, including resource competition among the larval stages, prevailing environmental conditions and reproductive interference in the form of satyrization. As the distribution and abundance of Ae. aegypti and Ae. albopictus have profound epidemiological implications, understanding the competitive interactions that influence these patterns in nature is important. While evidence for resource competition and environmental factors had been gathered from the field, the evidence for reproductive interference, though strongly inferred through laboratory trials, remained sparse (one small-scale field trial). In this paper we demonstrate that low rates (1.12-3.73%) of interspecific mating occur in nature among populations of these species that have co-existed sympatrically from 3-150 yrs. Finally this report contributes a new species-specific primer set for identifying the paternity of sperm extracted from field collected specimens.

“…aegypti survival. It has been previously documented that interspecific copulation and hybridization can reduce female reproductive success, but interspecific sexual harassment, which does not always result in interspecific copulation, can also adversely affect individual reproductive success and longevity by suppressing both sugar and blood feeding [47].

Demonstration of resistance to satyrization behavior in Aedes aegypti from La Réunion island

et al. 2020

Aedes aegypti and Aedes albopictus are competent vectors of arboviruses such as dengue and chikungunya viruses which co-exist in some areas, including La Réunion island, Indian Ocean. A type of reproductive interference called satyrization has been described in sympatric species where dominant species mating fails to produce hybrids and thus reduces the fitness and tends to control the spread of the other species. Here, we investigated satyrization in laboratory experiments to provide insights on the potential impact on Ae. aegypti of a control campaign including a sterile insect technique component against Ae. albopictus. Different mating crosses were used to test sympatric, conspecific-interspecific and allopatric effects of irradiated and non-irradiated male Ae. albopictus on female Ae. aegypti, including in a situation of skewed male ratio. Our results suggest that there was only a low level of satyrization between sympatric populations of Ae. aegypti and Ae. albopictus colonized from La Réunion island. A male Ae. albopictus to female Ae. aegypti ratio of 3:1 did not increase the level of satyrization. Female Ae. aegypti previously mated to male Ae. albopictus were not prevented from being inseminated by conspecific males. A satyrization effect was not seen between allopatric Ae. albopictus and Ae. aegypti strains from La Réunion Island either. The tested Ae. aegypti strain from La Réunion island has therefore developed full resistance to satyrization and so releasing sterile male Ae. albopictus may not suppress Ae. aegypti populations if an overflooding of irradiated male Ae. albopictus leads to similar results. The management strategy of two competent species in a sympatric area is discussed.

19Aedes aegypti and Aedes albopictus are competent vectors of arboviruses such as dengue and 20 chikungunya viruses which co-exist in some areas including La Réunion island. A kind of 21 reproductive interference called satyrization has been described in sympatric species where a dominant 22 species tends to control the spread of the other species. Here, we investigated satyrization in laboratory 23 experiments to provide insights on the potential impact on Ae. aegypti of a control campaign including a sterile insect technique component against Ae. albopictus. Different mating crosses were used to test 25 sympatric, conspecific-interspecific and allopatric effects of irradiated and non-irradiated male Ae. 26 albopictus on female Ae. aegypti, including in a situation of skewed male ratio. Our results suggest 27 that there was only a low level of satyrization between sympatric populations of Ae. aegypti and Ae. 28 albopictus colonised from La Réunion island. A male Ae. albopictus to female Ae. aegypti ratio of 3:1 29 did not increase the level of satyrization. Female Ae. aegypti previously mated to male Ae. albopictus 30 were not prevented from being inseminated by conspecific male Ae. aegypti. A satyrization effect was 31 not seen between allopatric Ae. albopictus and Ae. aegypti strains from La Réunion Island either. The 32tested Ae. aegypti strain from La Réunion island has therefore developed full resistance to satyrization 33 and so releasing sterile male Ae. albopictus may not suppress Ae. aegypti populations if an 34 overflooding of irradiated male Ae. albopictus leads to similar results. The management strategy of 35 two competent species in a sympatric area is discussed. 36Key words: Aedes albopictus, satyrization, sterile insect technique, mating 37 aegypti, respectively. Non-irradiated males of each species were also crossed with female mosquitoes 126 of the other species. Non-irradiated male Ae. aegypti and Ae. albopictus were also crossed with virgin 127 female Ae. aegypti and Ae. albopictus, respectively, and used as controls. 128Three replicates were performed for each cross with 50 males and 50 females transferred to 15 × 15 × 129 15 cm cages (MegaView Science Co. Ltd., Taiwan) when they were 3 days old for a period of 7 130 days to ensure enough time was allowed for mating.
