Abstract
Zamure (unfavorably higher temperature and humid conditions) in a silkworm rearing seat was studied to make clear the mechanism of Zamure in this paper. Measurements of CO2-concentrantion and air temperature were made in and above the rearing seat. The results may be summarized as follows:
It was found that the increase of numbers of diseased larvae in the first stage of rearing is closely related to both the high content of CO2-gas in the seat and rise in temperature at surface of the seat. The CO2-content in the seat increased with the accumulation of the litter of silkworm and rise of sourrounding air temperature. CO2-amount released from a given litter was found to increase with time. CO2-release from the seat was appreciably more in the case that silkworm larvae were on the seat surface than in the opposite case.
