MANAGEMENT OF DEFOLIATION CATERPILLARS AND WHITEFLY IN SOYBEAN CROP, MUNICIPALITY OF PARAGOMINAS, PARÁ
---Monitoring; Insect pests; Integrated management.
Soybean crops are affected by numerous pests that have caused significant losses at all stages of crop development. This study evaluated the efficiency of management practices on natural populations of Chrysodeixis includens, Anticarsia gemmantalis, adults and nymphs of Bemisia tabaci biotype b, in soybean cultivars, with the following treatments: T1. Producer management – PRO; T2. Integrated Pest Management – IPM and T3. Control – TST. The bioassay was performed in randomized blocks (DBC) with 3 treatments and 6 replicates. Monitoring was carried out using a beating cloth for caterpillars, the turned leaf technique for whitefly adults and the quantification of nymphs was recorded using a 10x magnifying mini magnifying glass (6 samples/treatment). The management systems influenced the populations of C. includen, A. gemmantalis, adults and nymphs of B. tabaci. Larger populations were observed in the reproductive stage of the crop. Climatic variables had little influence on these populations.
