We examined sperm storage patterns of doubly mated females in a species of tephritid fly (Anastrepha suspensa (Loew) [Diptera: Tephritidae]) with four sperm storage organs and an unusually complex reproductive system to elucidate possible reproductiv

The yellowjacket, Vespula squamosa (Drury) (Hymenoptera: Vespidae), is the only eusocial wasp that commonly has 2 social forms (monogyne and polygyne nests), has annual and perennial nests, facultatively usurps the nests of conspecifics, and parasiti

Summary A number of important behavioral and physiological traits distinguish both social forms of Solenopsis invicta Buren (Hymenoptera: Formicidae) and correlate with the Gp-9 locus within a supergene complex. These traits include fat body content,

With the exception of an airplane equipped with nets, no method has been developed that successfully samples red imported fire ant, Solenopsis invicta Buren, sexuals in mating/dispersal flights throughout their potential altitudinal trajectories. We

A major obstacle for many studies examining sperm competition and cryptic female choice in insects has been the identification and quantification of sperm stored in the sperm storage organs of females that have mated with two or more males. Historica

Ribosomal DNA sequence data has been important in elucidating molecular evolution, discerning phylogenetic relationships, and in developing species diagnostics. Species in the genus Anastrepha Schiner, particularly members of the Fraterculus Species

Insemination and fertilization are temporally dissociated in most insects thus creating conditions for female-mediated processes to influence paternity. One possible response to copulatory and postcopulatory sexual selection may be to increase the nu

Female insects with multiple sperm storage organs may potentially influence patterns of paternity by differential storage of sperm from competing males. The Caribbean Fruit Fly, Anastrepha suspensa, stores sperm differentially with respect to its thr

The association between the ventral nervous system and the sperm storage organs in Anastrepha suspensa Loew was examined to elucidate possible mechanisms that may influence sperm transport in the female reproductive tract. Such mechanisms are of impo

The lack of polymorphic genetic markers suitable for genotyping sperm, eggs, and all life stages of the important agricultural pest, Anastrepha suspensa, have prevented detailed genetic studies of its breeding system, reproductive dynamics, and popul
