Resumen en inglés

The West Indian fruit fly, Anastrepha obliqua (Macquart), is the second most important tephritid fruit fly in Mexico, infesting mango, hog plum and guava fruits. To control this pest, the Mexican government has implemented the use of the sterile insect technique (SIT), which involves the mass production, sterilization and release of flies. However, the A. obliqua laboratory males used in SIT are selected to a lesser extent by the wild females during competitiveness tests. The objective of this study was to compare the effects of males fed on fruit fly food enriched with Providencia rettgeri to those in males fed on food alone, assessing male mating competitiveness, capture of females using traps baited with males fed with the enriched diet and sex pheromone components. The results indicated that males fed with the diet enriched with P. rettgeri had increased mating competitiveness and captured more females in the field cage tests. However, no difference was observed in the proportion of volatile sex pheromone components identified during the calling of A. obliqua males. The results suggest the value of incorporating bacteria into the mass rearing technique of A. obliqua adults in order to improve the sexual competitiveness of males from the laboratory compared to wild males.

Resumen en inglés

The control of Anastrepha obliqua includes the sterilization of mass-reared insects grown in isolation in a constantly controlled environment. Through time, laboratory mass-reared colonies may produce flies with lower field performance. To recover the genetic variation and aptitude of mass-reared populations, wild insects are introduced into mass-reared colonies. Our aim in this study was to determine whether the host species from two localities influence the life history traits of A. obliqua. We collected flies as larvae from infested fruits of Spondias purpurea, S. mombin, Mangifera indica cv. 'piña', and M. indica cv. 'coche' from two localities in Chiapas, Mexico. There were significant differences in the mating competitiveness of males collected from mango cv. 'coche' compared with mass-reared males. There were no differences in the mating propensity between flies from the two localities, even in the number of matings, when weight was considered as a covariable. The mass-reared strain showed the earliest age at first oviposition. The locality affected the longevity and oviposition period, and these influenced the birth rate, intrinsic rate of increase, finite rate of population increase, mean generation time, and doubling time. According to the demographic parameters, the population of S. mombin would allow artificial colonization in less time, considering that it has a high reproduction rate starting at an early age. Even in the propensity test, it had the highest number of matings. However, males with greater sexual competitiveness and longevity for colonization corresponded to those collected from S. purpurea.

Resumen en inglés

The mango fruit cv. ‘Ataulfo’ niño is an underdeveloped fruit that has a split on the back and a pronounced peak, and among the current total supply of commercialized mangoes cv. ‘Ataulfo’, approximately 2% are classified as ‘Ataulfo’ niño, which are strongly infested by Anastrepha ludens (Loew) (Diptera: Tephritidae) and Anastrepha obliqua Mcquart. The objective of this study was to determine the tolerance to 150-Gy generic irradiation for fruit flies of the Anastrepha genus in comparison to the development of a hot water treatment (HWT) as phytosanitary treatments for mango fruits cv. ‘Ataulfo’ niño infested by A. ludens and A. obliqua. The results indicated that both treatments were effective; 150-Gy irradiation and HWT at 46.3–47°C for 51 min did not result in significant effects on the external and internal color, total sugar content, firmness, pH, or weight. The sensorial quality described by the appearance, flavor, color, and odor did not show any significant differences between treatments. For both A. ludens and A. obliqua, the third larval instar was the most thermotolerant. The efficacy test was conducted with an immersion time of 47 min. A. ludens did not survive, but for A. obliqua, three larvae out of a total of 6,890 did survive and pupate. Consequently, the confirmatory test consisted of submerging mangoes infested with thirdinstar A. ludens and A. obliqua in water at 46.3–47°C for 51 min. In total, 67,392 A. ludens and 22,086 A. obliqua larvae were treated, and no surviving larvae were observed.

Resumen en inglés

The sterile insect technique uses males that have been mass-reared in a controlled environment. The insects, once released in the field, must compete to mate. However, the mass-rearing condition supposes a loss of fitness that will be noticeable by wild females. To compare the fitness of wild males and mass-reared males, three competition settings were established. In setting 1, wild males, mass-reared males and wild females were released in field cages. In setting 2, wild females and wild males were released without competition, and in setting 3, mass-reared males and mass-reared females were also released without competition. Male fitness was based on their mating success, fecundity, weight and longevity. The fitness of the females was measured based on weight and several demographic parameters. The highest percentage of mating was between wild males and wild females between 0800 and 0900 h in the competition condition, while the mass-reared males started one hour later. The successful wild males weighed more and showed longer mating times, greater longevity and a higher number of matings than the mass-reared males. Although the mass-reared males showed the lowest percentage of matings, their fecundity when mating with wild females indicated a high fitness. Since the survival and fecundity of wild females that mated with mass-reared males decreased to become similar to those of mass-reared females that mated with mass-reared males, females seem to be influenced by the type of male (wild or mass-reared).

Resumen en inglés

In this study, we examined the activity of two serine proteases (chymotrypsin and trypsin) and two metalloproteases (carboxypeptidases A and B) during larval development in Anastrepha obliqua fed natural (mango fruit) and artificial (formulation used in mass-rearing) diets. Proteolytic activity of chymotrypsin, trypsin, carboxypeptidase A, and carboxypeptidase B was detected in the midgut of different instars of A. obliqua and was strongly affected by the pH and diet type. The protein content of the natural and artificial diets was similar. Enzymatic activity was higher in the midgut of the larvae fed the natural diet than in larvae fed the artificial diet. The activity of the endopeptidases (chymotrypsin and trypsin) was lower than those of the exopeptidases (carboxypeptidases A and B). The pH of the midgut varied from acidic to neutral. The results indicate that in the midgut of the larvae reared on both types of diet, the level of carboxypeptidase activity was approximately 100-fold greater than the level of chymotrypsin activity and 10,000-fold greater than the level of trypsin. In conclusion, carboxypeptidase A and B are the main proteases involved in the digestion of proteins in the larvae of A. obliqua. The natural diet showed a high bioaccessibility. A clear tendency to express high activities of chymotrypsin and trypsin was observed by the third instar. Our research contributes to the planning and development of novel bioaccessibility assays to understand the nutrition processing of A. obliqua larvae under mass-rearing conditions for sterile insect technique.
