Simultaneous effects of gamma radiation and gravitational acceleration on the life span of imagoes of Callosobruchus analis (F.) (Col. Bruchidae)
- 1. Centro de Energia Nuclear na Agricultura, Piracicaba (Brazil)
Description
Adults of Callosobruchus analis (F.) (Col. Bruchidae) were submitted, 24-48 hours after emergence, to 2160 and 8635 times 'g' for 50, 100 and 200 minutes. All treatments were also irradiated at 0.3, 0.6 and 0.9 kGY gamma radiation in a Cobalt 60 source, and results based on daily survival rate countings. The analysis of the results showed that at 0.1% confidence level, all factors (acceleration, time of acceleration and gamma radiation, to which the insects were submitted) were statiscally significant, both alone and/or in combination. However, when all the three factors were combined, the confidence level decreased to 5%. The correlation factor determined in the experiment ('tau') was 0.94, and the coefficient of variation 18.4%.

Abstract (Portuguese)
Submeteram-se adultos de Callosobruchus analis (F.) (Col., Bruchidae), (24-48) h apos emergencia, a 2160 e 8635 vezes 'g' durante 50, 100 e 200 min.. Todos os tratamentos foram tambem irradiados com doses de 0,3, 0,6 e 0.9 kGY de radiacao gama numa fonte de Cobalto-60. Basearam-se os resultados nas contagens da taxa de sobrevivencia diaria. Analise dos resultados mostrou que para um nivel de confianca de 0,1%, todos os fatores (aceleracao, tempo de aceleracao e radiacao gama, aos quais os insetos foram submetidos) foram estatisticamente significantes, tanto isoladamente como em combinacao. Observou-se um decrescimo do nivel de confianca para 5% quando os tres fatores foram combinados. Determinou-se um fator de correlacao ('tau') na experiencia, de 0,94, sendo o coeficiente de variacao 18,4%. (M.A.)Additional details
