This study is realized with the aim of proposing an alternative in the use of pesticides of synthesis in the fight
against Dermestes spp, insects beetles, devastating main things of the dried fish. The activity adulticides and
larvicides some powder of leaves of Crataeva religiosa Forst (Capparidaceae) was tested on Dermestes spp. The
results allowed to say that this powder of leaves is very effective against the larvas of diverse stage and the adults
of Dermestes spp associated to the smoked-dried fish with salt. The smallest measure D1 (0,05%) allows 86,31%
of mortality corrected to larvas and to adults, 93,01%. With the biggest dose D6 (0,4%), 88% of mortality
corrected to larvas is registered and 98 % of mortality corrected at the adults.
