Reproductive and Metabolic Differences Between Aedes aegypti and Ae. albopictus (Diptera: Culicidae)

Abstract

Aedes albopictus (Skuse) females were more likely to develop eggs after they ingested small blood meals than were Aedes aegypti (L.) when both species were maintained under the same suboptimal adult nutritional regimen. The longevity of adult female Ae. albopictus under conditions of starvation was also significantly greater than that of Ae. aegypti. Analyses of total body proteins, lipids, and glycogen indicated that the increased reproductive efficiency of Ae. albopictus may be a result of its greater reserves accumulated during a longer larval period.

Quantitative aspects of the regulation of ovarian development in selected anautogenous Diptera: integration of endocrinology and nutrition

“…These have shown that (i) the proportion of females that develop any mature oocytes increases from 0 to near 100% over a certain range of amounts of proteincontaining food or amino acid mixture given, (ii) the number of oocytes matured by those individuals that do mature any oocytes increases over this range and (iii) the number matured continues to increase as the amount of protein-containing food or amino acid mixture given increases above this range (Figure 1). These relationships are well illustrated by results obtained with L. cuprina Barton Browne et al, 1979), Aedes albopictus (Klowden & Chambers, 1992) and Culex pipiens pallens (Uchida et al, 1992). In L. cuprina, the proportion of females maturing oocytes increased from 20% to 90% when the dry weight of a standard liver exudate ingested increased from 2.4 to 3.6 mg. Over this range, the mean number of oocytes matured increased from 140 to 173 (Barton .…”

“…There have been a number of studies of the relationship between the extent of ovarian development and the amount of any one kind of protein-containing food ingested (e.g., Edman & Lynn, 1975;Williams et al, 1979;Barton Browne et al, 1979;Hayles & Matthiessen, 1987;Briegel, 1990b) or introduced by enema into the midgut (e.g., Lea et al, 1978;Briegel, 1985;Klowden, 1987;Klowden & Chambers, 1992;Klowden, 1993;Takken et al, 1998). In addition, in a related kind of experiment, amino acid mixtures of the same composition but differing in concentration have been infused into the haemocoel of female mosquitoes at different rates for different periods of up to 48 h, thus providing a range of total amounts of the amino acid mixture administered (Uchida et al, 1992).…”

Identity and transfer of male reproductive gland proteins of the dengue vector mosquito, Aedes aegypti: Potential tools for control of female feeding and reproduction

“…stephensi suggest that Supp_Aedes002636 is a candidate to test for a role in the post-mating increase in female egg production observed in Ae. aegypti (Feyvogel et al, 1968;Klowden and Chambers, 1991;Klowden and Chambers, 1992;Klowden, 1993).…”

“…aegypti and transferred to females during mating influence reproductive and feeding behavior (reviewd in Clements, 1999a;Klowden, 1999). Studies that have compared phenotypes of mated and unmated females or used direct injection of mosquito male accessory gland homogenate into unmated females have reported post-mating effects on female mosquito behavior including flight (Taylor and Jones, 1969;Jones and Gubbins, 1978;Jones and Gubbins, 1979;Jones, 1981;Chiba et al, 1990;Chiba and Shinkawa, 1992), response to host cues (Lavoipierre, 1958;Judson, 1967;Hartberg, 1971;Klowden and Lea, 1979), oviposition (Gillett, 1955;Leahy and Craig, 1965;Hiss and Fuchs, 1972;Ramalingam and Craig, 1976), fertility and ovarian development (Feyvogel et al, 1968;Klowden and Chambers, 1991;Klowden and Chambers, 1992;Klowden, 1993), blood digestion (Edman, 1970;Downe, 1975), and sexual refractoriness (Fuchs et al, 1968;Fuchs and Hiss, 1970). The stimulus for post-mating effects may not be the same for all mosquitoes (Klowden, 2006).…”

Evolution of resistance to satyrization through reproductive character displacement in populations of invasive dengue vectors

“…However, it is considered unlikely that larval competition alone could account for the rapid competitive reductions of A. aegypti within 1-3 y in the southeastern United States (7,13,14) or in Bermuda, where A. albopictus more recently displaced A. aegypti with comparable rapidity (15). In addition to larval competition, hypotheses to explain these displacements include greater reproductive efficiency in A. albopictus (16); apparent competition mediated by the intestinal gregarine protozoan Ascogregarina taiwanesis (12); and asymmetric reproductive interference between A. aegypti and A. albopictus (4,13). Greater reproductive efficiency in A. albopictus, although possibly beneficial in the long term, does not adequately explain the rapid declines of A. aegypti.…”
