Foi obtida floracao precoce em plantas jovens de seringueira (Hevea brasíliensis) de IAN 873 e PFB 5, de quatorze meses de idade, tratadas para esse fim. Os fitorreguladores Cumarina e Ethephon foram eficientes so quando aplicados em plantas aneladas. A poda das raizes ou o crescimento forcado dos caules na posicao horizontal produziram efeito de inducao de floracao; porem na posicao horizontal observou-se queda de dominancia apical. O uso de Dimetil Sulfoxido aparenternente aumentou a penetracao dos fitorreguladores nas folhas. Nenhum tratamento foi eficiente para inducao de floracao precoce em hibridos de H. bendiamiam (clones de IAN 717 e Fx 3899). E possivel que as plantas jovens tenham sido induzidas a floracao principalmente pelo bloqueio da exportação de fitoassimilados e consequente acumulo de substrato organico no caule, o que aumenta sua disponibilidade em zonas quiescentes do meristema apical. |

We used electropenetrography to quantify and compare counts and durations of selected waveforms, produced by adult females of the stink bug Dichelops furcatus (F.). Insects fed on immature soybean pods and immature seed heads of four spring cereals: wheat, black oat, barley, and rye. On all foods, bugs spent over 60% of their plant access time in non-probing activities. This total waveform duration was significantly longer on barley and rye compared to those on soybean and oat; wheat was intermediate. Considering only probing activities, bugs spent longer durations (ca. 2×), on soybean and oat compared to barley, rye, and wheat plants. Bugs produced significantly more pathway events on soybean and rye than on wheat and barley; with a significantly shorter duration per event on rye. The counts and durations of xylem ingestion did not differ among foods. Cell rupturing activities on seeds were longer on soybean (ca. 23%) and oat (ca. 21%), than on barley and rye (ca. 6%). The durations of ingestion events on seeds were significantly shorter on soybean (over 3×) compared to those on barley and wheat; oat and rye were intermediate. However, the ingestion duration per insect did not show significant difference among foods. Results demonstrated that D. furcatus spent more time overall in probing activities on soybean and oat; whereas, rye and barley presented the worst feeding behavior. This study provides important background information for further quantitative studies of stink bugs on different plants, such as development of resistant host plants. Key words: crop plant, feeding behavior, electrical penetration graph, electropenetrography MenosWe used electropenetrography to quantify and compare counts and durations of selected waveforms, produced by adult females of the stink bug Dichelops furcatus (F.).
