Description
With the objective of checking some effects of gamma radiation on the sugarcane borer (Diatraea saccharalis (F.)), one-day ald adult males were irradiated with doses from 0-50 krad at 5 krad intervals. The insects were submitted to gamma irradiation in a 60Co source, with a dose rate of 350 krad/hour. No significant difference was found in male longevity between treatments. Also no significant difference as found in sexual activity, represented by number of spermatophores per female, and in fertility. Fertility and egg viability decreased significantly with the dose, the viability reaching 0 at 50 krad. Occurrence of dominant lethal mutation, induced by radiation, was noted, which resulted in the death of the embryo before larvae emergence. (Author)
Abstract (Portuguese)
Com o objetivo de se verificar alguns efeitos da radiacao gama na broca de cana-de-acucar (Diatraea saccharalis (F.)) irradiaram-se machos adultos de um dia de idade com doses que variaram de 0 a 50 krad em intervalos de 5 krad. Os insetos foram submetidos a radiacao gama em um irradiador de 60Co, com taxa de dose de 350 krad/hora. Entre os tratamentos nao houve diferenca significativa na longevidade dos machos. Tambem na atividade sexual, representada pelo numero de espermatoforos por femea e na fecundacao, nao se verificou diferenca significativa. A fertilidade e a viabilidade dos ovos decresceram significativamente com a dose, chegando a viabilidade de 0 na dose de 50 krad. Verificou-se a ocorrencia de mutacoes letais dominantes induzidas pela radiacao, provocando a morte do embriao antes da eclosao da larva. (Autor)Additional details
