Post-harvest pest population based on observation method at bulog warehouse

Abstract

Postharvest pests are the biggest problem during storage, so it is necessary to monitor for control measures. This study aims to monitor the population using two systems of monitoring methods. This research was conducted in three regencies where Bulogs rice was stored. The monitoring using namely direct and indirect method. Direct monitoring was carried out by determining five sample points diagonally, each sample point measuring 1×1 m and then directly monitoring all of the insects pest found. While indirect monitoring were carried out by taking samples using a probe with three times at each sample point and the collected rice was weighed as much as 300 grams and then count the population in the rice. Monitoring were made on comodities that had been fumigated for two months. The results showed that the highest population of postharvest pests was found in the direct visual monitoring method and the pests with the highest population was Cryptolestes, then Tribolium, and the lowest was Rhyzopertha.
