Insect radiosensitivity: Dose curves and dose-fractionation studies of dominant lethal mutations in the mature sperm of 4 insect species

Effects of gamma radiation on life stages of the Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae)

“…This holokinetic chromosome structure ensures that most radiation-induced breaks do not lead to the loss of chromosome fragments as in the species with monocentric chromosomes (Marec et al 2005). The radioresistance of Lepidopteran species was discussed by LaChance (1967) and LaChance and Graham (1984). It was reported that holokinetic or diffuse centromere chromosomes do not automatically confer a high degree of radioresistance.…”

“…Hallman (2000) reported that some stored-product moths, especially the Angoumois grain moth, Sitotraga cerealella (Oliver) and the Indian meal moth Plodia interpunctella (Hü bner), were among the most tolerant arthropods to radiation. In comparison with dipteran species, Lepidoptera require much higher levels of ionizing radiation to obtain full sterility (LaChance and Graham 1984). The main cause of this difference is thought to reside in the different kinetic organization of chromosomes in these two groups of insects.…”

“…This larval eclosion could be attributed to this slow embryonic development and late expressing lethality when the larvae fully developed. The events leading to a dominant lethal mutation in the radioresistant Lepidopteran species require a greater number of hits to prevent the hatching of the larvae (LaChance and Graham 1984).…”

An Initiative the Used of Sterile Insect Technique (SIT) To Control Filariasis in Indonesia

“…ambient atmosphere, doserate irradiation, temperature, cell stage and characteristics, developmental stage and age, sex, size and weight, diapauses, nutritional state have significant influences in sterilization process and need to be optimized [43][44][45][46].…”

Biological Control of Lobesia botrana (Lepidoptera: Tortricidae) Larvae by Using Different Formulations of Bacillus thuringiensis in 11 Vine Cultivars Under Field Conditions

“…It is believed that the centromere difference could play a major role in radiation sensitivity . However, it was suggested that possible molecular mechanisms responsible for the high radio-resistance in Lepidoptera might include an inducible cell recovery system and a DNA repair probe (LaChance and Graham 1984). Another genetic phenomenon found in Lepidoptera is that females are more sensitive to radiation than are males of the same species, and inherited sterility in irradiated lepidopteran males is caused mainly by induced translocations that lead to the production of genetically unbalanced gametes in F 1 individuals, resulting in their sterility (Tothova and Marec 2001).…”
