Abstract： The main technical aspects and notes of the observation on insect material with scanning electron microscope（SEM） were introduced. The main process of observation by SEM includes pretreatment of the material， double fixation， clean， dehydration， replacement， drying， glue station， spraying metal coating and observation. Through the contrast of experimental pictures， the key technology for obtaining good observation effect was summarized and discussed. The observation technology has wide popularization value and reference significance.

Key words： insect material； scanning electron microscope（SEM）； microscopic observation
