摘要

In Burkina Faso, the availability of <i><span style="font-family:Verdana;">Acacia</span></i><span style="font-family:Verdana;"> </span><i><span style="font-family:Verdana;">macrostachya</span></i><span style="font-family:Verdana;"> </span><span style="font-family:Verdana;">“</span><span style="font-family:Verdana;">Zamnè</span><span style="font-family:Verdana;">”</span><span style="font-family:Verdana;"> </span><span style="font-family:Verdana;">seeds throughout the year is threatened by the attacks of pests. So, the effectiveness of airtight (hermetic) storage for the preservation of these seeds was evaluated using 20</span><span style="font-family:Verdana;">-</span><span style="font-family:Verdana;">litre plastic jars and 50 kg PICS bags as hermetic containers with 50 kg polypropylene bags as controls. Seeds of </span><i><span style="font-family:Verdana;">Acacia</span></i><span style="font-family:Verdana;"> </span><i><span style="font-family:Verdana;">macrostachya</span></i><span style="font-family:Verdana;"> (17.5 kg) were stored in each of these storage devices for six</span><span style="font-family:Verdana;"> </span><span style="font-family:Verdana;">months under ambient conditions in the laboratory. The number of storage pest </span><i><span style="font-family:Verdana;">Bruchidius</span></i><span style="font-family:Verdana;"> </span><i><span style="font-family:Verdana;">silaceus</span></i><span style="font-family:Verdana;"> increased significantly in polypropylene bags from 235 to 715 individuals on average/500</span><span style="font-family:Verdana;"> </span><span style="font-family:Verdana;">g of seeds. But in PICS bags and plastic drums, the number of this pest did not vary significantly (191 and 239 individuals on average/500</span><span style="font-family:Verdana;"> </span><span style="font-family:Verdana;">g of seeds for plastic jars and PICS bags respectively). In both hermetic devices, we found few individuals of another major storage pest </span><i><span style="font-family:Verdana;">Caryedon<
