Identification and Age-Dependance of Pteridines in the Head of Adult Mexican Fruit Fly, Anastrepha ludens
Pteridines from head capsules of adult Anastrepha ludens were identified and evaluated as a tool for age determination of flies. Pteridines were identified by a combination of TLC, HPLC and UV and fluorescence spectroscopy. Tentative identifications were obtained for one red pterine, neodrosopterin, and three orange pterines, drosopterin, isodrosopterin and aurodrosopterin. Five pterines with b...
متن کاملLongevity-fertility trade-offs in the tephritid fruit fly, Anastrepha ludens, across dietary-restriction gradients.
Although it is widely known that dietary restriction (DR) not only extends the longevity of a wide range of species but also reduces their reproductive output, the interrelationship of DR, longevity extension and reproduction is not well understood in any organism. Here we address the question: 'Under what nutritional conditions do the longevity-enhancing effects resulting from food restriction...
متن کاملBiodemography of a long-lived tephritid: reproduction and longevity in a large cohort of female Mexican fruit flies, Anastrepha ludens.
Age of sexual maturity, daily and lifetime reproductive rates, and life span were recorded in a laboratory cohort of Mexican fruit flies consisting of over 1100 females maintained individually. The results revealed that, relative to the medfly, the Mexfly is slower maturing (14 vs 17 days), more fecund (1400 vs 650-1100 eggs/female), and longer lived (50 vs 35 days). The results reinforced the ...
متن کاملLasa et al.: Advances in Developing a Dry Trap for Anastrepha ludens 1135 TOWARDS DEVELOPMENT OF A MASS TRAPPING DEVICE FOR MEXICAN FRUIT FLY ANASTREPHA LUDENS (DIPTERA: TEPHRITIDAE) CONTROL
The use of simple and economic traps with long lasting lure dispensers is key for implementation of mass trapping strategies against pestiferous fruit flies. Simplicity, cost, ease of assembly, storage and transportation were considered during evaluation of a folding conical trap for mass trapping the Mexican fruit fly, Anastrepha ludens. The application of deltamethrin to the lid of the trap r...
متن کاملFitness Cost Implications of PhiC31-Mediated Site-Specific Integrations in Target-Site Strains of the Mexican Fruit Fly, Anastrepha ludens (Diptera: Tephritidae)
Site-specific recombination technologies are powerful new tools for the manipulation of genomic DNA in insects that can improve transgenesis strategies such as targeting transgene insertions, allowing transgene cassette exchange and DNA mobilization for transgene stabilization. However, understanding the fitness cost implications of these manipulations for transgenic strain applications is crit...
