摘要: Plant extract have been recognized as important natural source of insecticide. Herein, we assessed the toxicity leaves-extract and seeds-extract Annona mucosa (Annonaceae) against brown stink bug, Euschistus heros (F.) (Hemiptera: Pentatomidae), a soybean pest in Neotropical America. For this, bioassays with nymphs adults were conducted using concentrations 5, 10, 20, 40 80 mg.mL -1 leaves seeds A. DMSO (10%), control. Ten replicates by treatment, five (3 rd instar) replicate (bioassay nymphs) one couple ( 5.0mg.mL , while treated do not exhibit difference between treatments. In survival was reduced, when seed at higher than 20mg.mL reduction up to 92 days contrast A drastic fecundity fertility observed, which highlight deleterious action reproductive potential E. . This is first report about (leaves seed) on our results suggest that promising for control bug.
