五种化学性质不同的油（三种植物油、矿物油和聚乙二醇）以每千克种子5.0毫升油的剂量有效地保护豇豆、长爪豇豆（Vigna unguiculata）免受斑点豆象（Callosobruchus maculates）的侵害。油引起种子表面的卵和幼虫的高死亡率，但对成功进入种子的个体没有影响。缺乏石油特有的活性表明，保护性质是物理的，而不是化学的。贮藏30天后，处理过的种子比新处理过的种子对产卵雌虫更有威慑力，但贮藏的种子对卵和幼虫的毒性较小。因此，油施用可能仅在有限的时间段内有用。
Applications of five chemically differing oils (three vegetable oils, mineral oil, and polyethylene glycol) at dosages of 5.0 ml of oil per kg of seed effectively protected cowpeas, Vigna unguiculata , from Callosobruchus maculates (F.). Oils caused high mortality of eggs and larvae on the seed surface, but had no effect on individuals that successfully entered the seed. A lack of oil-specific activity indicated that the protective property was physical rather than chemical. After 30 days in storage, treated seeds were more deterrent to ovipositing females than were newly treated seeds, but the stored seeds were less toxic to eggs and larvae. Oil application may therefore be useful for only a limited period of time.
