Discarded vehicle tire casings are an important artificial habitat for the developmental stages of numerous vector mosquitoes. Discarded vehicle tires degrade under ultraviolet light and leach numerous soluble metals (e.g., barium, cadmium, zinc) and organic substances (e.g., benzothiazole and its derivatives [BTs], polyaromatic hydrocarbons [PAHs]) that could affect mosquito larvae that inhabit the tire casing. This study examined the relationship between soluble zinc, a common marker of tire leachate, on mosquito densities in tire habitats in the field, and tested the effects of tire leachate on the survival and development of newly hatched Aedes albopictus and Aedes triseriatus larvae in a controlled laboratory dose-response experiment. In the field, zinc concentrations were as high as 7.26 mg/L in a single tire and averaged as high as 2.39 (SE±1.17) mg/L among tires at a single site. A. albopictus (37/42 tires, 81.1%) and A. triseriatus (23/42, 54.8%) were the most widespread mosquito species, co-occurred in over half (22/42, 52.4%) of all tires, and A. triseriatus was only collected without A. albopictus in one tire. A. triseriatus was more strongly negatively associated with zinc concentration than A. albopictus, and another common mosquito, C. pipiens, which was found in 17 tires. In the laboratory experiment, A. albopictus per capita rate of population change (l') was over 1.0, indicating positive population growth, from 0 to 10,000 mg/L tire leachate, corresponding to 8.9 mg/L zinc concentration, but steeply declined to zero from 50,000 to 100,000 mg/L tire leachate (44.5-89.0 mg/L zinc). In contrast, A. triseriatus l' declined at the lower concentration of 100 mg/L tire leachate (0.05 mg/L zinc), and was zero at 500, 10,000, 50,000 and 100,000 mg/L tire leachate. These results indicate that tire leachate can have severe negative effects on populations of container utilizing mosquitoes at concentrations commonly found in the field. Superior tolerance to tire leachate of A. albopictus compared to A. triseriatus, and possibly other native mosquito species, may have facilitated the replacement of these native species as A. albopictus has invaded North America and other regions around the PeerJ Preprints | https://doi.org/10.7287/peerj.preprints.3065v1 | CC BY 4.0 Open Access | rec Abstract 15 Discarded vehicle tire casings are an important artificial habitat for the developmental stages of 16 numerous vector mosquitoes.

Abstract. Upon mating, male mosquitoes transfer accessory gland proteins (Acps) that induce refractoriness to further mating in females. This can also occur because of cross-insemination by males of related species, a process known as mating interference (satyrization). This mechanism could explain the competitive displacement of resident Aedes aegypti by the invasive Aedes albopictus where they co-occur. We tested this hypothesis in mosquito populations in Florida. A new polymerase chain reaction species diagnostic applied to sperm dissected from 304 field-collected females revealed bidirectional cross-mating in five (1.6%) individuals. Cross-injections of females with Acps showed that Ae. albopictus males induced monogamy in heterospecific females but not Ae. aegypti males. Despite its low frequency in the areas under study, the first evidence of cross-mating in nature and the asymmetric effect of Acps on mating suggest that satyrization may have initially contributed to the observed competitive reduction of Ae. aegypti by invasive Ae. albopictus in many areas.

“…albopictus colonies were established in 2011 from field collections of aquatic immatures from artificial containers, such as discarded tires or cemetery vases. Sympatric lines were derived from collections at a salvage yard in Vero Beach (VB), FL, where the two species have co-occurred for at least two decades (O'Meara et al 1993), while the allopatric line of Ae. aegypti was collected in Key West (KW), FL, and the allopatric line of Ae.…”

The Effects of Interspecific Courtship on the Mating Success ofAedes aegyptiandAedes albopictus(Diptera: Culicidae) Males

Satyrization, a form of asymmetric reproductive interference, has recently been shown to play a role in competitive displacements of Aedes aegypti (L.) by Aedes albopictus (Skuse). Furthermore, female Ae. aegypti from populations in sympatry with Ae. albopictus have evolved reproductive character displacement and changes in mating behavior to reduce interspecific mating. In this article, we examine evolutionary responses of males to interspecific mating and show that satyrization has also evoked reproductive character displacement in males. We demonstrate that the presence of heterospecific females negatively influences conspecific mating success in male Ae. aegypti, most likely due to misdirected courting or mating efforts, and that males of this species from populations in sympatry with Ae. albopictus have evolved to be less influenced by the presence of heterospecific females than their allopatric counterparts. Conversely, we suggest that the presence of conspecifics may, in some circumstances, increase interspecific mating. This study demonstrates that co-occurrences of these two invasive species may lead to evolution and adaptation of reproductive behaviors to changing circumstances. Understanding the processes driving development of mate choice preferences or avoidance mechanisms may help predict future changes in the distribution and abundance of insect vectors or pests.
