1. Tapachula-7 is a genetic sexing strain of Anastrepha ludens (Loew) (Diptera: Tephritidae) developed for the application of the sterile insect technique (SIT). To improve the sexual performance of this strain, a mass-reared colony was established from males selected for their sexual competitiveness. 2. Males from selected colonies are more sexually competitive than nonselected males. The present study aimed to analyse the demographic changes recorded in the study colony throughout four consecutive generations, comparing this colony with the parental colony and a wild strain. 3. The results obtained showed that, in the selected strain, fecundity increased, whereas survival diminished, compared with the laboratory parental strain. The increases in fecundity rates were observed at the first generation after selection. No changes were observed in the duration of the reproductive period in the selected strain. 4. Compared with wild flies, selected flies had lower life expectancy, earlier and shorter reproductive period, and greater daily fecundity at young ages (10–30 days), although with lower lifetime fecundity rates. 5. The four generations of the selected colony showed similar patterns of survival and reproduction. The better mating performance and the increase in early fecundity suggest that selection could contribute to improve rearing efficiency and SIT effectiveness.

Resumen en inglés

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is considered one of the most important pests worldwide because of its direct damage to fruit and vegetable production, and restrictions imposed to commercialization of horticultural commodities by countries free of the pest. It was introduced to Brazil in 1901 and to Costa Rica in 1955, from where it spread across the Central American region, reaching Guatemala and Mexico in 1976 and 1977, respectively. In response, the governments of Guatemala, Mexico, and the USA joined efforts to (1) contain further northward spread of the pest, (2) eradicate it from the areas it had invaded in southernMexico, and (3) in the longer termeradicate it from Guatemala and eventually from the rest of Central America. To this effect, cooperative agreements were subscribed between the three countries and also between the USA and Belize. This allowed regional cooperation against the Mediterranean fruit fly and the creation of the Moscamed Programme. The programme was the first area-wide large-scale application of the sterile insect technique (SIT) against this pest. By 1982, the Programme had achieved its first two objectives with the containment of the northward advance of the pest, and its eradication from the areas it had invaded in the states of Chiapas and Oaxaca in southern Mexico. Furthermore, by 1985 the Mediterranean fruit fly had been eradicated from areas in Guatemala located at the border with Mexico. Since then, the programme has had years with significant territorial advances in the eradication of the pest from areas within Guatemala, combined with years when it had setbacks resulting in losses of the territorial gains. Nevertheless, during 4 decades, the programme has effectively served as an effective containment barrier maintaining the Mediterranean fruit fly-free status of Belize, Mexico, and the USA.

It has also protected and increased the Mediterranean fruit fly-free areas in Guatemala. As a result, it has protected the assets of horticultural producers and contributed during this period to the development of multibillion dollar export industries in these countries. This paper provides an historical review of the programme and describes briefly how technological innovations and decision-making tools have contributed to programme efficiency. It also discusses how non-technical and external factors have limited the eradication process and further programme advance within the Central American region.

Resumen en inglés

The sexual performance of Anastrepha ludens males of the Tapachula-7 genetic sexing strain, produced via selection based on mating success, was compared with that of males produced without selection in competition with wild males. Mating competition, development time, survival, mass-rearing quality parameters and pheromone production were compared. The results showed that selection based on mating competitiveness significantly improved the sexual performance of offspring. Development time, survival of larvae, pupae and adults, and weights of larvae and pupae increased with each selection cycle. Differences in the relative quantity of the pheromone compounds (Z)-3-nonenol and anastrephin were observed when comparing the parental males with the F4 and wild males. The implications of this colony management method on the sterile insect technique are discussed.

Resumen en inglés

In this study, rearing systems for, and the quality and demographic parameters of, a wild strain (WS) and two laboratory strains (LSs; one maintained on a torula yeastcasein diet and the other on a starter-gel diet) were determined for the American guava fruit fly Anastrepha striata (Schiner). No differences were observed between the LSs, but there were significant differences between the LSs and WSs. The LSs had the highest values for larval recovery, pupal weight, egg hatch, number of eggs/female per day, net reproductive rate and intrinsic rate of increase. Therefore, during a short oviposition period, the LSs had a high fecundity. There were no differences in pupation at 24 h and larval weight between the WS and LS. However, the values of parameters, adult emergence, female and male life expectancies, age at first oviposition, oviposition and post-oviposition periods and mean generation time were the highest in the WS.

Resumen en español

Se desarrollo una dieta para Anastrepha striata (Schiner), caracterizando los cambios ocurridos en los parámetros de cría y calidad durante seis generaciones. En el primer experimento se utilizaron huevos que registraron entre 20 y 40% de eclosión al momento de sembrarse sobre las dietas utilizadas en las crías de Anastrepha ludens (Loew), A. obliqua (Macquart), A. serpentina (Wiedemann) y Ceratitis capitata (Wiedemann). En estas dietas, la mayor recuperación larvaria fue de 4.8%. En el segundo experimento, en la dieta AOII modificada de A. obliqua fue sustituida la fuente de proteína, y la levadura torula por Nutrifly™, torula-caseína y proteína hidrolizada. En la dieta formulada con 4.83% de Nutrifly™, 15% de polvo de olote, 8.0% de harina de maíz, 8.33% de azucar, 0.23% de benzoato de sodio, 0.11% de nipagín, 0.13% de ácido cítrico y 63.37% de agua, se obtuvo la mayor recuperación de larvas en comparación con las otras dietas formuladas con diferentes fuentes de proteína. En el tercer experimento, se caracterizó la adaptación de las larvas a la dieta Nutrifly™. Durante seis generaciones, el peso de larva y de pupa disminuyó de la generación parental a la primera generación, y ambos parámetros se incrementaron a partir de la tercera generación, hasta registrar un peso similar al observado en la generación progenitora. La recuperación larvaria y la emergencia de adultos se incrementó de la generación parental a las siguientes generaciones y mantuvo dicha tendencia durante las cinco generaciones, y solamente la recuperación larvaria registró una ligera disminución durante la tercera generación. Se discuten los resultados que la adaptación de Anastrepha striata a una dieta larvaria artificial requiere de al menos cinco generaciones.

Resumen en inglés

An artificial larval diet for Anastrepha striata (Schiner) was developed and the changes in the rearing and quality parameters through 6 generations during the adaptation were characterized. In the first experiment we tested diet formulations that had already been developed for the mass-rearing of Anastrepha ludens (Loew), A. obliqua (Macquart), A. serpentina (Wiedemann) and Ceratitis capitata (Wiedemann) by sowing A. striata eggs (20–40% hatched) in each diet. In those tested diets, the maximum larval recovery percentage was 4.82%. In the second experiment, in the AOII modified diet of A. obliqua, we substituted the protein source, torula yeast by Nutrifly™, torula yeast-casein and hydrolyzed protein. A formulated diet contained 4.83% Nutrifly™, 15% corn cob fractions, 8.0% corn flour, 8.33% sugar, 0.23% sodium benzoate, 0.11% nipagin, 0.13% citric acid, and 63.37% water allowed higher larval survival compared to diets with different protein sources. In the third experiment, we evaluated adaptation of the larvae to Nutrifly diet. Over 6 generations, the larval and pupal weights and pupation percentage decreased from parental to first generation and increased after the third generation, recovering the initial value. Larval recovery and adult emergence increased from parental generation to the next generations; and was maintained during the next 5 generations. Larval recovery only a light decreased in the third generation. The laboratory colonization of A. striata reared on this artificial diet required at least 5 generations for the larvae to adapt to the artificial diet and increase pupal weight and adult emergence.

Resumen en español

Se comparó la biología y el comportamiento sexual entre una cepa de laboratorio con fenotipo silvestre (LFS) con una cepa de laboratorio con fenotipo mutante (LFM) de Anastrepha ludens (Loew), que se caracteriza por una coloración del cuerpo clara y ojos amarillo cremoso, para determinar su potencial como marcador genético en los programas de control mediante el uso de la técnica del insecto estéril. Los resultados del estudio indicaron que los individuos de la cepa mutante LFM no difieren significativamente de los individuos de la cepa LFS respecto a su fecundidad, fertilidad y supervivencia de inmaduros, así como en la emisión de feromona sexual. Esto es indicativo de que podría ser adaptada a las condiciones de cría masiva. Sin embargo, las pruebas de apareamiento indicaron que aunque los insectos LFM copularon con los insectos de campo de fenotipo silvestre (CFS), presentaron cierto grado de aislamiento y bajos porcentajes de apareamiento de los machos tanto con hembras CFS y LFS, lo cual implica que no sea recomendable el uso de la cepa mutante LFM como marcador genético en programas que utilizan la técnica del insecto estéril, para el control de la mosca Mexicana de la fruta.

Resumen en inglés

We compared the biology and sexual behavior between a strain of laboratory with wild phenotype (LFS) and a strain of laboratory with mutant phenotype (LFM) of Anastrepha ludens (Loew), characterized by clear coloration of the body and creamy yellow eyes to determine their potential as genetic marker in the control programmes through the use of the sterile insect technique. The survey results indicated that individuals of the LFM mutant strain not differ significantly from individuals of the LFS strain respect to their fecundity, fertility and survival of immature stages, as well as in the emission of sexual pheromone. This indicates that could be adapted to mass-rearing. However, mating tests indicated that although the LFM insects mated with the insects of field of wild phenotype (CFS), presented some degree of isolation and low percentages of mating of males with both LFS and CFS females, implying that is not recommended the use of the LFM mutant strain as genetic marker in programs that use the sterile insect technique, for the control of the Mexican fruit fly.

Resumen en inglés

A long-standing question in biology is whether longevity is greater in females or in males for most non-human species. This is an open question for the majority of species because little is known about the nature of the underlying mortality differences. 2. Examination of mortality data on approximately 600 000 medflies of each sex revealed a demographic paradox-male medflies possessed the higher life expectancy (average longevity) but female medflies were usually the last to die. 3. The underlying demographic cause of this incongruency was a male-female mortality crossover-females exhibited higher mortality than males to around 3 weeks, lower mortality than males from about 3-8 weeks, and mortality approximately equal to that of males thereafter. 4. The findings help explain the ambiguity of male-female longevity differences in the literature, suggest that relative male-female survival cannot be used as a proxy for sex mortality differences, shed light on sex biasing of older ages, and undercore the difficulties with comparative aspects of ageing. 5. We propose a general framework for sex-mortality differentials in which the underlying mortality factors are grouped into three interrelated categories: constitutional endowment, reproductive biology and behaviour. This framework provides conceptual structure as well as insights into how complex patterns in the sex-mortality ratio can arise.
