Ms. Nahdy, BEAN SIEVING, A POSSIBLE CONTROL MEASURE FOR THE DRIED BEAN BEETLES, ACANTHOSCELIDES-OBTECTUS (SAY) (COLEOPTERA, BRUCHIDAE), Journal of Stored Products Research, 30(1), 1994, pp. 65-69
The possibility of controlling Acanthoscelides obtectus in stored bean
s by repeated sieving was investigated under laboratory conditions at
Kawanda Research Station in Uganda. Repeated sieving of the stored bea
ns every 5 days over a period of 50 days gave excellent control of A.
obtectus for up to 150 days after the last sieving. The method was eff
ective for lightly infested grain as well as for heavily infested grai
n. As coffee drying trays are suitable for sieving the beans and as th
ese are readily available in the coffee growing areas of Uganda, there
is a high probability of adoption of this means of bruchid control by
farmers and traders.
