The influence factor of phototaxis and photophobism behavior of the dominant predatory enemies-Propylea japonica (Thunberg) was investigated by behavior measure.

However,the response rate could be detected at the lowest intensity and not arrived to the summit at the strongest yet;(3) The effect of sex to response to the spectral sensitivity and intensity is not significant;(4) There was not significant photophobism response to light for the ladybird,the behavior probably derived from phototaxis or partly due to random movements.

The effects of storage conditions such as temperature, storing in the dark and package of nitrogen on acid values, peroxide values and TBA values of stir-fried sunflower seed during storage were studied in this paper.
