INSECT PEST SPECIES DIVERSITY POST CROP AT SOME LIVESTOCK FOODS IN SUB-PROVINCE BOLAANG MONGONDOW. The purpose of research aim to be to know species diversity and abudance of population of pest post at livestock food. To get data about pest type post crop at livestock food is done by livestock food sampling counted 1 kg, then is looked after during 10 days in laboratorium, and activity hereinafter is done abservatiion about pest type post crop at each livestock food. Insect pest type found at livestock food is identified based on insect morphology. Livestock food type taken at palce of storages, that is corn, paddy bran, konsentrate, and fish meal. Then is calculated pest species diversity post crop at livestock food. Number of pest types post crop found at livestock food in Kabupaten Bolaang Mongondow 12 types. In district of poigar number of pest types post found 12, whike lolak 9 type, pest type pascapanen which is highest found at corn and paddy bran.

Abundance of highest population at bijian corn there is in poigar 90 tails, and Kecamatan Lolak it’s the population only reachs 45.5 tails. For highest paddy bran livestock food there is at type Tribolium sp, population Tribolium sp at highest paddy bran there is in Kecamatan poigar 27 tails and low at kecamatan lolak 23.5 tails. Level of pest species diversity post crop bijian highestcorn is found in Kecamatan Poigar H’ = 1.62, while Lolak only reach H’ = 1.35, Value level of trhis varicety pertained low, because value level of pest species diversity livestock food at cron under H’ = 3.5  Keywords: Diversity, insect post crop, fee
