| Popis: | Abstract: The aim of this work was to determine the effect of Azadirachta indica and Tagetes erecta leaf extract, as well as Jatropha curcas resin extract on the control of Carmenta foraseminis larvae in Theobroma cacao fruits. The study was conducted using a complete random block design (CRBD) with 6 treatments (T1:0%, T2:10%, T3:20%, T4:30%, T5:40% and T6:50%), 3 replicates and 10 fruits per experimental unit. The variables evaluated were: number of hatched larvae-NHL and number of attacked fruits. Extracts from , Azadirachta indica,Tagetes erecta leaves and Jatropha curcas resin at concentrations greater than 40% were efficient in the control of Carmenta foraseminis in Theobroma cacao fruits in the fruiting phase. Further studies should be carry out to determine the concentration of secondary metabolites in Azadirachta indica, Tagetes erecta leaves and Jatropha curcas resin at different maturation stages for a more efficient use in the control of the insect pest. |
