“…Pupae were obtained from the Moscafrut (SADER-SENASICA) facility, located in Metapa de Dominguez, Chiapas, Mexico, from a colony that had been mass-reared for more of 150 generations ( Orozco-Dávila et al, 2014 ). All of the pupae used in this study were irradiated for 48 h pre-emergence with 80 Gy of gamma radiation using a Cobalt 60 source ( Toledo et al, 2004 ).…”

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.

“…In the conditions of the present study, the resting surface area in both cages were almost the same and above the value of 2. In the Mediterranean fruit fly (Diptera: Tephritidae) and Anastrepha oblique (Diptera:Tephritidae), Liedo et al [47] and Orozco-Davila et al [48], respectively, demonstrated that an increase in the surface resting area within adult cages of the mother colony, as well as the use of low adult cage density during rearing resulted in strains with higher mating competitiveness. Thus, a role of the cage volume cannot be conclusively ruled out, and specifically internal surface area, on egg productivity.…”

Background Anopheles arabiensis is one of the major malaria vectors that put millions of people in endemic countries at risk. Mass-rearing of this mosquito is crucial for strategies that use sterile insect technique to suppress vector populations. The sterile insect technique (SIT) package for this mosquito species is being developed by the Insect Pest Control Subprogramme of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. To improve mass-rearing outcomes for An. arabiensis, the question of whether the egg production by females would be affected by the size of the adult holding cages, the source of the blood meal and the total number of pupae that could be loaded into the cages was addressed and finally the impact of adding additional pupae to the cage daily to maintain adult numbers on egg productivity assessed.MethodsMass production cages of two different volumes, two different sources of blood meal (bovine and porcine) and two different population densities (cages originally loaded with either 15,000 or 20,000 pupae) were tested and evaluated on the basis of eggs produced/cage or per female. Males and females pupae with a ratio of 1:1 were added to the cages at day 1 and 2 of pupation. The emerging adults had constant access to 5% sugar solution and blood fed via the Hemotek membrane feeding system. Eggs were collected either twice a week or daily. A generalized linear model was used to identify factors which gave significantly higher egg production.ResultsNeither cage volume nor blood meal source affected egg production per cage or per female. However, increasing population density to 20,000 pupae had a negative effect on eggs produced per cage and per female. Although high density negatively impacted egg production, adding 1000 daily additional pupae compensating for daily mortality resulted in a substantial increase in egg production. Moreover, in all tests the first and the third egg batches collected were significantly higher than others eggs batches. With the equipment and protocols described here and routinely used at the Insect Pest Control Laboratory (IPCL), it was possible to produce up to 120,000 eggs/cage/day.ConclusionThese results demonstrated that 15,000 is the optimal number of pupae to be loaded into the Anopheles Mass production cages. Under this condition, an average of 40 eggs per female was obtained for five gonotrophic cycles. However, an improvement in egg production can be achieved by daily addition, to the original 15,000 pupae, of one thousand pupae a day. Interestingly, feeding females with bovine or porcine blood using both large and small versions of the mass production cage did not affect egg productivity.

“…Anastrepha obliqua (Macquart), the West Indian fruit fly, is a polyphagous species of greater economic concern within the genus because it infests ca. 104 fruit species in 27 plant families (Norrbom, 2004), mainly mango (Mangifera indica L.) and Spondias species in Mexico (Orozco-D avila et al, 2014), Colombia (Mangan et al, 2011), the Caribbean Islands (Mangan et al, 2011), and Brazil (Zucchi, 2000). Anastrepha obliqua is characterised by a wide geographic distribution ranging from northern Mexico to southern Brazil, including the Caribbean Islands (Fu et al, 2014).…”

The West Indian fruit fly, Anastrepha obliqua (Macquart) (Diptera: Tephritidae), is a quarantine pest in Colombia that infests economically important plants, although little is known about its population dynamics. In this study, cytochrome oxidase subunit I (COI) and NADH dehydrogenase subunit 6 (ND6) mitochondrial genes were concatenated to characterise the genetic diversity and population structure of A. obliqua, associated with two factors: (1) ecosystem differences in two geographical regions of southwestern Colombia (the inter-Andean valley of the Cauca River and the mountain region), and (2) the host plants present in the area. Additionally, a first approach was made at understanding the species demographic history. Seven haplotypes were found with Kimura 2-parameter (K2P) genetic distances between 0.1 and 4%. Haplotype genealogies and demographic analyses suggest that the population of A. obliqua in southwestern Colombia is the result of introductory events of multiple populations of A. obliqua. However, the data indicate that the population genetic structure could be related to the ecological differences of the two regions being studied. Significant differences were also found among the distribution of haplotype frequencies of A. obliqua with regard to the diversity of host plants. This study is the first to provide an understanding of the population dynamics of A. obliqua in Colombia, which may ultimately contribute to strategies, such as sterile insect technique (SIT), for the management of the pest.
