The cryptochrome (cry) gene and a mating isolation mechanism in tephritid fruit flies.
Two sibling species of tephritid fruit fly, Bactrocera tryoni and Bactrocera neohumeralis, are differentiated by their time of mating, which is genetically determined and requires interactions between the endogenous circadian clock and light intensity. The cryptochrome (cry) gene, a light-sensitive component of the circadian clock, was isolated in the two Bactrocera species. The putative amino ...
متن کاملThe biology of nonfrugivorous tephritid fruit flies.
This review is the first comprehensive treatment of the biology of nonfrugivorous fruit flies of the family Tephritidae. Feeding habits of destructive and useful species, morphology of immature stages, and hypotheses regarding structural homology and the evolutionary biology of nonfrugivorous tephritids are reviewed, including zoogeography and theories involving resource heterogeneity, guild st...
متن کاملPheromones, Male Lures, and Trapping of Tephritid Fruit Flies
Both sex pheromones and male lures appear to play an important role in the mating systems of many species of economically important tephritid species. Typically, stationary males emit pheromone attractive to searching females, and recent evidence indicates that naturally occurring male lures may function as precursors in pheromone synthesis. Here, we review (i) the basic biology of sex pheromon...
متن کاملMating-induced recombination in fruit flies.
In traditional deterministic models the conditions for the evolution of sex and sexual behavior are limited because their benefits are context dependent. In novel and adverse environments both multiple mating and recombination can help generate gene combinations that allow for rapid adaptation. Mating frequency often increases in conditions in which recombination might be beneficial; therefore,...
متن کاملVariation in the post‐mating fitness landscape in fruit flies
Sperm competition is pervasive and fundamental to determining a male's overall fitness. Sperm traits and seminal fluid proteins (Sfps) are key factors. However, studies of sperm competition may often exclude females that fail to remate during a defined period. Hence, the resulting data sets contain fewer data from the potentially fittest males that have most success in preventing female rematin...
