Nymphicidal effect of vegetal extracts of Annona mucosa and Anonna crassiflora (Magnoliales, Annonaceae) against rice stalk stink bug, Tibraca limbativentris (Hemiptera, Pentatomidae)
This study aimed to verify the chloroform-methanol nymphicidal action of extracts of Annona mucosa leaves and seeds and of A. crassiflora seeds on second instar nymphs of rice stalk stink bug, Tibraca limbativentris. For each extract the concentrations of 0.5%, 1.0%, 2.0%, 4.0%, 8.0%, and two contro...

| description | This study aimed to verify the chloroform-methanol nymphicidal action of extracts of Annona mucosa leaves and seeds and of A. crassiflora seeds on second instar nymphs of rice stalk stink bug, Tibraca limbativentris. For each extract the concentrations of 0.5%, 1.0%, 2.0%, 4.0%, 8.0%, and two control treatments (water and Tween80®) were used. The results show that the seed extracts of A. mucosa and A. crassiflora have insecticidal activity against the T. limbativentris nymphs with statistical significance for all concentrations when compared with controls. The seed extract of A. mucosa showed the higher toxicity with greater than 75% mortality at a concentration of 1.0% in the first 24 h after application. The leaf extract of A. mucosa presented the lowest toxicity with no more than 40% mortality. The seed extract of A. crassiflora showed intermediate toxicity among all the tested extracts, and the nymph's mortality exceeded 80% for the highest concentration after 120 h of application. Considering these results, we were able to observe that the seeds extract of A. mucosa may be an alternative for the control of bed bug nymphs T. limbatriventris, especially for small producers. |
