The Indian meal moth( Plodia interpunctella) is the major insect pest of stored pine pollen products. Focusing on the effectiveness in storage pest control and safety for product quality,the effect of various treatments during pine pollen production such as drying,sifting,sterilizing,and cell-breaking etc. on the control of Indian meal moth was investigated. The results showed that any of the following treatments could control and kill the eggs or larvae of Indian meal moth during pine pollen production: sifting with a sieve more than 180 mesh,drying at 49 ℃lasting for 120 min,sterilizing by 12 k Gy60Co-γ-ray irradiation,mechanical cell-breaking or pressed into tablets,fumigating with 7 g·m- 3sulfuryl fluoride for 6. 5 hours or dealing with for 24 hours at- 8 ℃. Partly or fully combinations of all these measures mentioned above are economical,practical and safe to effectively block the invasion or damage of Indian meal moth to pine pollen products.
