“…In our study, for both F 1 and F 2 generations, percentage of egg hatch was greatly affected by treatment and the effect was dose-dependent i.e., the higher the radiation dose, the lower the egg hatch. Our data are consistent with those reported for other lepidopteran species (North and Holt 1968b;Graham et al 1972;Henneberry and Clayton 1981;Carpenter et al 1987;Bughio 1988, Marec et al 1999Bloem et al 1999a, b;Carpenter et al 2001).…”

The effects of substerilizing doses of gamma radiation on the longevity and level of inherited sterility in the Australian moth Teia anartoides Walker were determined. Six day-old male pupae were treated with 0, 100, and 160 Gy of gamma radiation by using a 1.25 MeV Cobalt60 irradiation source. Laboratory studies of male longevity showed that radiation had little impact in adult moths of the P1, F1, and F2 generations. Inherited deleterious effects resulting from irradiation were observed in the progeny of F1 and F2 generations. Outcrosses between substerile parental males or their highly sterile male progeny to wild-type females did not affect female fecundity. However, adverse effects were observed for these crosses in the rates of successful egg hatch and postembryonic development. Fertility was always greater in out-crosses involving a P1 male than in any of the F1 out-crosses. F1 males were always more sterile than F1 females, and the level of sterility for the F1 and F2 generations was higher than that of the controls. The incidence of larval and pupal mortality was higher in the F2 than the F1 generation. A dose of 100 Gy had the highest success in inducing deleterious effects that were inherited through to the F2 generation. Our results indicated that the use of partially sterilizing doses of radiation has good potential as a selective strategy for management or eradication of T. anartoides.

“…This recovery of fertility at the F 3 generation has also been reported in pink bollworm (Graham et al 1972); Ostrinia furnacalis (Guenee) (Zhang et al 1993); and fall armyworm, Spodopetera frugiperda (J.E. Smith) (Arthur et al 2002).…”

“…In practice, the success of IL × IL matings are seldom measured, due to difficulties in producing enough offspring in the laboratory to make a robust estimate. ILincompatibility is usually assumed, perhaps because of the relatively low survival rate of IL females in many species ( Carpenter et al , 2005 ), although, conversely, the fertility of the irradiated line has been shown to recover in subsequent generations in some species ( Graham et al , 1972;Zhang et al , 1993;Arthur et al , 2002;Wee et al , 2005 ). Other aspects of IL fitness, such as survivorship and competitiveness are rarely measured, but sensitivity analysis suggests that IL competitiveness at least is less likely to have a major influence on the outcome of SIT programmes.…”

1 The sterile insect technique (SIT) involves the release of large numbers of sterile or partially-sterile insects into a wild pest population to dilute the number of successful wild matings, with the eventual aim of eradication or area-wide suppression. General population models, encompassing a wide range of SIT types, were used to derive principles for optimizing the success of SIT, with particular emphasis on the application of partial sterility leading to inherited sterility in the F 1 population. 2 The models show that inherited sterility can only be guaranteed to be more effective than complete sterility if matings between irradiated-lineage partners are unsuccessful. This is widely assumed but rarely examined experimentally. 3 The models allow the critical overflooding ratio, c , to be calculated for a particular target species, suggesting the release rate required to prevent population increase. Successful eradication using SIT alone should aim for a substantially higher release rate than suggested by c . 4 The models show that pest populations may continue to increase in the first few generations of SIT releases, regardless of release rate, as irradiated-lineage individuals infiltrate the population. This does not necessarily imply that the SIT programme will be unsuccessful in the longer term. 5 For pests with overlapping generations, the models suggest that frequent small releases may be more effective than less frequent large releases, particularly when the average release rate is close to the critical threshold for success.
