S.  aEfficacy of bioactive compounds and their association with different cowpea cultivars against their major stored pest.h[electronic resource]  c2020  aStored 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.  aBotanical insecticides  aGenetic resistance  aInsecticide resistance  aPlant pests  aGorgulho  aInseticida de Origem Vegetal  aResistência Genética  aVigna Unguiculata1 aOLIVEIRA, J.
