Highest egg viability (82.89%) was found in the eggs removed by a razor from the granulated Maraco paper sheet used by AM-Tech rearing methodology whereas egg viability was lowest (64.89%) in the case of egg removed from black organdy with potassium hypochlorite solution. Modest egg viability (75.56%) was observed in the eggs laid on black organdy and removed by a razor.]]>Carvalho, C.F., M. Canard and C.
