Stored grain insects are controlled with fumigant insecticides which can select resistant insect populations and cause environmental and applicator contamination. Thus, resistant cultivars and chemical constituents of essential oils are an alternative to the almost exclusive use of these insecticides. The effects of the combination of cowpea cultivars Vigna unguiculata (L.) Walp. with chemical constituents of essential oils against Callosobruchus maculatus were determined. Four cowpea cultivars: BRS Tracuateua, BR 17 Gurgueia, Epace 10 and Sempre Verde (insect rearing) untreated were used in the experiments and combined with chemical constituents of essential oil: eugenol, geraniol and trans‐anethole. The biological parameters observed were: total egg number and eggs per grain, egg viability (%), insects emerged and insects per grain, immature stage viability (%), instantaneous rate of growth (ri), insect dry weight (mg), grain weight loss (%) and egg‐adult period.

生物活性化合物的功效以及它们与不同的cow豆栽培品种对主要贮藏害虫的联系。

用熏蒸杀虫剂控制储存的谷类昆虫，它们可以选择抗性昆虫种群并引起环境和施药者污染。因此，精油的抗性品种和化学成分是这些杀虫剂几乎排他性使用的替代方法。cow豆品种Vigna unguiculata（L.）Walp组合的影响。含有针对马齿Call的精油化学成分被确定。实验中使用了四个未经处理的cow豆品种：BRS Tracuateua，BR 17 Gurgueia，Epace 10和Semper Verde（昆虫饲养），并与香精油的化学成分：丁子香酚，香叶醇和反式茴香脑结合。观察到的生物学参数为：总卵数和每粒卵的卵数，卵的存活率（％），每粒谷物中出现的昆虫和昆虫，未成熟阶段的存活率（％），瞬时生长率（ri），昆虫干重（mg），谷物体重减轻（％）和成卵期。
