Abstract Present study envisages the potential of triple layer bags for reducing pulse beetle infestation under laboratory conditions over six months of storage. It was observed that when chickpea grain was stored in jute bags with bruchid infestation, the germination percentage decreased significantly from 84.67 to 18.67% in six months of storage. But, the grain stored in jute bags without infestation the germination percentage decreased from 92.00 to 73.33% only. On the other hand, grains stored in triple layer bags with bruchid infestation, the germination percentage merely decreased from 86.00 to 78.33% in six months of storage and triple layer bags without infestation the germination percentage only decreased from 91.67 to 90.67%. The per cent grain damage over a period of six months storage also increased significantly from 14.54 to 70.67% and 0.00–26.45% in jute bag with bruchid infestation and jute bag without infestation, respectively. However, per cent grain damage in triple layer bags with bruchid infestation increased only from 15.15 to 25.70% and triple layer bags without bruchid infestation showed negligible increase from 0.00 to 2.64% grain damage in six months of storage. The corresponding per cent weight loss of infested grain was increased significantly from 8.51 to 55.67% in six months of storage in jute bag with bruchid infestation and from 0.00 to 15.08% in jute bag without infestation. Whereas, per cent weight loss of infested grain in triple layer bags with bruchid infestation increased only from 7.83 to 15.70 in six months of storage and triple layer bags without bruchid infestation recorded a mere per cent increase in weight loss from 0.00 to 1.48%. Benefit cost ratio showed that grains stored in triple layer bags for 6 months has highest benefit cost ratio (1.23) compared to jute bag storage (0.39).

将鹰嘴豆粒 (Cicer arietinum L.) 储存在三层袋中可防止在实验室条件下由 Callosobruchus maculatus (F.)（鞘翅目：Chrysomelidae）造成的损失

摘要 目前的研究设想了三层袋在实验室条件下储存超过六个月的减少脉冲甲虫侵扰的潜力。据观察，当鹰嘴豆籽粒被储存在带有 bruchid 感染的黄麻袋中时，在储存 6 个月后，发芽率从 84.67% 显着下降到 18.67%。但是，未经侵染的黄麻袋中储存的谷物发芽率仅从 92.00 下降到 73.33%。另一方面，被布氏菌侵染的三层袋贮藏的谷物，在贮藏6个月后，发芽率仅从86.00%下降至78.33%，而未受侵染的三层袋贮藏时，发芽率仅从91.67%下降至90.67%。六个月储存期间的谷物损坏百分比也从 14.54 显着增加到 70。分别为 67% 和 0.00-26.45% 在有 bruchid 侵染的黄麻袋和没有侵染的黄麻袋中。然而，在储存 6 个月后，有 bruchid 侵染的三层袋中的谷物损坏百分比仅从 15.15% 增加到 25.70%，而没有 bruchid 侵染的三层袋中的谷物损坏百分比从 0.00 增加到 2.64% 可以忽略不计。在有 bruchid 侵染的黄麻袋中储存 6 个月后，受侵染谷物的相应重量损失百分比从 8.51% 显着增加到 55.67%，而在没有侵染的黄麻袋中则从 0.00% 增加到 15.08%。然而，在储存 6 个月后，有 bruchid 感染的三层袋中受感染谷物的重量损失百分比仅从 7.83 增加到 15.70，而没有 bruchid 感染的三层袋中的重量损失仅从 0.00 增加到 1.48%。
