Peas (Pisum sativum) are toxic to some stored-product insects. The repellent effect of fractions of pea seed to stored-product insects was evaluated in multiple-choice tests in which wheat kernels were dusted with fractions rich in either protein, fibre or starch at 0.001 to 10% (wt:wt). There was a negative correlation between pea protein concentration and the number of adults found in grain for Cryptolestes ferrugineus and Sitophilus oryzae, but not for Tribolium castaneum. Pea fibre repelled C. ferrugineus adults but not S. oryzae and T. castaneum. Pea starch did not repel any of the insects. One-week old and 6-week old C. ferrugineus were equally repelled by pea protein. Repellency was detectable 1h after exposure. Cryptolestes ferrugineus and S. oryzae did not become habituated to the repellent action of pea protein even after 4 weeks of exposure. Habituation was observed, however, when C. ferrugineus was exposed to pea fibre for 4 weeks. In a two-choice bioassay (0 vs. 0.1% and 0 vs. 1% pea protein), the pea-protein-treated grain had significantly fewer insects (C. ferrugineus, S. oryzae, Sitophilus zeamais, T. castaneum, and Tribolium confusum) than untreated grain. The properties of the pea protein fractions seem well suited for developing a natural stored grain protectant.

豌豆（Pisum sativum）组分对贮藏昆虫的驱避作用

豌豆（Pisum sativum）对一些储藏产品的昆虫有毒。在多项选择测试中评估豌豆种子部分对储藏产品昆虫的驱避效果，其中向小麦籽粒撒上富含 0.001 至 10% (wt:wt) 的蛋白质、纤维或淀粉的部分。豌豆蛋白浓度与谷物中发现的 Cryptolestes ferrugineus 和 Sitophilus oryzae 的成虫数量呈负相关，但与 Tribolium castaneum 无关。豌豆纤维排斥 C. ferrugineus 成虫，但不排斥 S. oryzae 和 T. castaneum。豌豆淀粉不排斥任何昆虫。一周大和 6 周大的 C. ferrugineus 被豌豆蛋白同样排斥。暴露后 1 小时可检测到排斥性。Cryptolestes ferrugineus 和 S. 即使在暴露 4 周后，稻瘟病菌也没有习惯于豌豆蛋白的驱虫作用。然而，当 C. ferrugineus 暴露于豌豆纤维 4 周时，观察到了习惯。在两项选择的生物测定中（0 对 0.1% 和 0 对 1% 豌豆蛋白），豌豆蛋白处理过的谷物中的昆虫明显减少（铁锈菌、稻瘟病菌、Sitophilus zeamais、T. castaneum 和Tribolium confusum) 比未经处理的谷物。豌豆蛋白组分的特性似乎非常适合开发天然储藏谷物保护剂。和 Tribolium confusum) 而不是未经处理的谷物。豌豆蛋白组分的特性似乎非常适合开发天然储藏谷物保护剂。和 Tribolium confusum) 而不是未经处理的谷物。豌豆蛋白组分的特性似乎非常适合开发天然储藏谷物保护剂。
