Effect of gamma radiation on the male sterility and other quality parameters of peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae)

“…However, in choosing an optimal sterilization dose for SIT, a balance needs to be reached between the levels of sterility and mating competitiveness of males (Toledo et al 2004;Parker, Mehta 2007). Insects that receive a too low dose are not sufficiently sterile and those that receive a too high dose may be uncompetitive, reducing the effectiveness of SIT as it requires that There appears to be a general consensus that the irradiation process negatively affects the total competitiveness of males (Pereira et al 2007) and that one simple way to lessen this impact, and thereby to increase the effectiveness of SIT, is to reduce the sterilizing dose (Shelly et al 2005). In general, data from our laboratory bioassay demonstrate that the effect of irradiation on peach fruit fly is consistent with the results for other tephritid fruit fly species.…”

Mating compatibility among populations of codling moth Cydia pomonella Linnaeus (Lepidoptera: Tortricidae) from different geographic origins

“…For all tests PM was above 20%, and therefore, none of the data were rejected. The mean PM (of the total replicates for each pairwise comparison) of each test was lower than that normally encountered with fruit flies Vera et al 2006;Orozco-Dá vila et al 2007;Pereira et al 2007), it fluctuated between 23.9 AE 5.9% and 45.0 AE 24.2%, which indicates adequate conditions for mating. Average PM values were lower than 30% in the Argentina-Syria, Armenia-New Zealand, Canada*-Chile, and Syria-New Zealand* tests, and higher than 40% in the Argentina-Canada*, Canada*-Syria, Canada-New Zealand* and Switzerland*-Canada* tests.…”

“…2006; Orozco‐Dávila et al. 2007; Pereira et al. 2007), it fluctuated between 23.9 ± 5.9% and 45.0 ± 24.2%, which indicates adequate conditions for mating.…”

“…(2002) found no evidence of pre‐mating isolation between wild Mediterranean fruit fly populations from nine countries over five continents and between those and four genetic sexing strains. Likewise, no significant isolation was found between Mediterranean fruit fly populations from different islands of Madeira (Pereira et al. 2007).…”

An integrative multidisciplinary approach to understanding cryptic divergence in Brazilian species of theAnastrepha fraterculuscomplex (Diptera: Tephritidae)

“…We acknowledge that this phenomenon could have been a factor in our results, which limits the strength of our conclusions. However, lines of evidence from several other studies in similar tephritid systems that compared mating compatibility between wild and laboratory strains (including A. fraterculus from other regions) suggest that the changes in laboratory strains often do not result in divergence in mating compatibility Allinghi et al, 2007;Pereira et al, 2007;Rull et al, 2012). Consequently, we suggest that the main reason for the sexual incompatibility between the PIR and the Southern region populations observed in our study might be reasonably due to either intrinsic differences in its sexual and/or genetic traits that affect mate recognition or interpopulational differences among the wild sources of A. fraterculus.…”
