Insecticidal activity of plant extracts on Dysmicoccus brevipes in pineapple
| Resumo: | Abstract Dysmicoccus brevipes is an insect that can cause many losses in the pineapple crop. Thus, it is necessary to study alternative methods to chemical control. The objective of this study was evaluate the insecticidal activity of extracts of Azadiractha indica and Cyperus iria on D. brevipes in pineapple. Tests were carried out on: colonization of D. brevipes and growth of pineapple plants; mortality of this insect by the application of extracts directly and by residual contact, with five repetitions in completely randomized design. Each repetition was composed by one plant to test of colonization of D. brevipes and growth of pineapple plants, and a Petri dish with ten female nymphs of 2nd instar to evaluate the mortality of D. brevipes by application of extracts directly and by residual contact. The treatments tested were: 1) control 1 (water); 2) control 2 (insecticide Evidence( WG, imidacloprid 700 g kg-1); 3 and 4) aqueous extract of A. indica at 5% and 10%, respectively; 5 and 6) aqueous extract of C. iria at 5% and 10%, respectively. The data were submitted to analysis of variance and Scott-Knott’s test at the 5% level of significance. It was found that extracts A. indica 10% and C. iria 5% and 10% sprayed once in pineapple plants may adversely affect D. brevipes population, not interfering with pineapple growth. Therefore, these extracts have a potential to be used in Integrated Management of Pests associated with other control methods. |
