Title: Dispersal and longevity of wild and mass-reared Anastrepha Ludens and Anastrepha Obliqua (Diptera: Tephritidae)

Abstract

The rates of dispersal and survival of sterile mass-reared laboratory flies and sterile wild flies of Anastrepha ludens (Loew) and Anastrepha obliqua (Macquart) were estimated and compared with a regular rectangular array of 64 food-baited traps spaced 60 m between traps around the release point in Tapachula Chiapas, Mexico. The traps were scored every day during the first week, and then every 3 d over a 30-d period. For A. obliqua, the number of males recaptured was higher than that of females, while for A. ludens, females were recaptured more frequently than males. The recapture rate for the wild strains ranged from 0.6-24.8% for A. ludens and 1.3-16.2% for A. obliqua and the corresponding ranges for the mass-reared strains were 0.5-7.1% and 0.5-3.0% respectively. The life expectancy was 4.7 d for wild and 4.3 d for mass-reared A. obliqua males but 3 and 2 d, respectively, for wild and mass-reared A. ludens males. The net displacement of A. ludens and A. obliqua ranged approximately from 100-250 m and took place mostly on the first day. Wild A. ludens moved to the northwest from the release point while the mass-reared strain moved to the west. The A. obliqua wild flies movedmore » to the west, while the mass-reared strain shifted to the southwest. We discuss the implications of our findings as to the spacing and frequency of sterile fly releases for the suppression of wild populations.

Las trampas fueron revisadas y evaluadas diariamente durante la primera semana y despues cada tres dias hasta completar 30 dias. Para A. obliqua la cantidad de machos capturados fue mayor que la cantidad de hembras; mientras que para A. ludens las hembras fueron capturadas con mayor frecuencia que los machos. La recaptura de moscas silvestres de A. ludens fue de 0.6 a 24.8%, para A. obliqua fue del 1.3 al 16.2%, para moscas de laboratorio fue de 0.5 a 7.1 y 0.5 a 3%, respectivamente. La esperanza de vida correspondio a 4.7 y 4.3 dias para machos silvestres y de laboratorio de A. obliqua respectivamente; mientras que 3 y 2 dias fueron para los machos silvestres y de laboratorio de A. ludens . La dispersion para A. ludens y A. obliqua fue de 100 a 250 m tanto para individuos silvestres como de laboratorio. Los adultos de A. ludens silvestre se desplazaron del punto central de liberacion al noroeste, los individuos de laboratorio se movieron hacia el oeste del plano Cartesiano. A su vez los adultos de A. obliqua silvestre se movieron hacia el oeste y las de laboratorio hacia el suroeste. Discutimos las implicaciones de nuestros resultados con relacion al espaciamiento y frecuencia de las liberaciones de moscas esteriles para la supresion de poblaciones silvestres. (author)« less
