The use of three different sizes of sand i.e. coarse sand (0.50-1.00 mm) medium sand (0.25-0.50 mm) and fine sand (0.10-0.25 mm) to cover the seeds to a depth of about 3 cm. to prevent or reduce oviposition by the bruchid beetle [Callosobruchus maculatus (F)] by using mungbean seed (U-Tong 1) as the experimental material with the initial moisture content and percentage of germination of 8 and 92.50 percent respectively. All sizes of the sand tested could also completely prevent the outside insects from laying egg on the seed below the sand cover (p0.01). But in the case of seed with the bruchid's eggs on them were covered with sand, the fine sand could completely prevent the damage of the seeds while in the treatment of the coarse and medium sand, the damage occurred gradually and reached 100,00 percent in the fifth month
