“…In crosses of A. aegypti females with A. albopictus males, the origin of the female had a significant effect [χ (1) 2 = 42.29, P < 0.001] on the likelihood of insemination, with females from allopatric populations more likely to be inseminated than females from sympatric populations ( Fig. 1 A and C).…”

“…These results have implications for increased risks of dengue transmission where these vector species meet worldwide. C ompetitive displacement is based on the principle that two species cannot simultaneously occupy the same niche, leading to population reduction of one by interspecific competition (1). This phenomenon has been documented in nature, often in the context of biotic invasions or species introductions for biological control (2)(3)(4).…”

Recently, the highly invasive Asian tiger mosquito, Aedes albopictus, rapidly displaced resident populations of the yellow fever mosquito, Aedes aegypti in the southeastern United States and in Bermuda. Although multiple mechanisms of competitive displacement have been hypothesized, recent evidence of cross-insemination between these species in nature and the sterilizing effects of male accessory gland products asymmetrically favoring A. albopictus in interspecific matings support a role for satyrization (a form of reproductive interference) to explain the rapid displacements. Because of the drastic reproductive loss of A. aegypti females satyrized by A. albopictus males, we predicted selection for prezygotic isolation in populations of A. aegypti sympatric with A. albopictus. Exposures in cages demonstrated that female A. aegypti from populations in Florida sympatric with A. albopictus for the past 20 y were significantly less likely than nearby allopatric populations to mate with heterospecific males. Cross-inseminations of A. albopictus females by A. aegypti males were significantly less common, supporting the one-way direction of displacements observed in nature. Our results indicate rapid sexual selection leading to reproductive character displacement and the potential for satyr-resistant A. aegypti to recover from competitive displacements. These results have implications for increased risks of dengue transmission where these vector species meet worldwide.

“…De Bach (1966) noticed that established species are more often displaced than completely excluded, and this might eventually happen to the Ms biotype. However, we cannot exclude the possibility that the Ms biotype is in the process of being almost completely excluded by B, as happened to the A biotype in the United States .…”

Microsatellites reveal extensive geographical, ecological and genetic contacts between invasive and indigenous whitefly biotypes in an insular environment

SummaryHuman-mediated bioinvasions provide the opportunity to study the early stages of contact between formerly allopatric, divergent populations of a species. However, when invasive and resident populations are morphologically similar, it may be very difficult to assess their distribution in the field, as well as the extent of ecological overlap and genetic exchanges between invasive and resident populations. We here illustrate the use of data obtained from a set of eight microsatellite markers together with Bayesian clustering methods to document invasions in a group of major tropical pests, Bemisia tabaci, which comprises several morphologically indistinguishable biotypes with different agronomic impacts. We focus on the island of La Re´union, where an invasive biotype (B) has recently been introduced and now interacts with the resident biotype (Ms). The temporal and spatial distribution, host-plant range and genetic structure of both biotypes are investigated. We showed (i) that, without prior information, clustering methods separate two groups of individuals that can safely be identified as the B and Ms biotypes; (ii) that the B biotype has invaded all regions of the island, and showed no signs of genetic founder effect relative to the Ms biotype ; (iii) that the B and Ms biotypes coexist in sympatry throughout most of their geographical ranges, although they tend to segregate into different host plants ; and finally (iv) that asymmetrical and locus-specific introgression occurs between the two biotypes when they are in syntopy.

“…Pheidole megacephala is one of the most invasive ant species in the tropics, (Wetterer 2012) and was described as a top predator and competitor of other insects (Hoffmann et al 1999;Dejean et al 2007), making this species a principal actor in the process of competitive displacement (Debach 1966;Holway & Suarez 1999). In Broward County (Florida), P. megacephala has displaced many other ant species and can be locally dominant (Warner & Scheffrahn 2013).…”
