“…The preferred downward position during feeding, although referred to several species of pentatomids, such as E. meditabunda on soybean stem (Panizzi and Machado-Neto, 1992), T. limbativentris on rice stem (Ferreira and Martins, 1984) and D. melacanthus on maize stem (Ávila and Panizzi, 1995) was never quantified and demonstrated. More recently, two other species of pentatomids were reported to feed on rice stem downward (again, not quantified): Hypatropis inermis (Stål) (Krinski et al, 2015) and the small black stem bug, Glyphepomis spinosa Campos & Grazia, which is considered a new pest on rice in the central and northern Brazilian states (Alves et al, 2012).…”

The Neotropical green-belly stink bug, Dichelops melacanthus (Dallas) is a major pest of maize, Zea mays L. in the main production areas of Brazil. It usually feeds on the stems of young plants (seedlings) causing heavy damage by affecting the plant growth and mitigating seed yield. Laboratory studies were conducted to determine body position (upward or downward) of the bug on plant (seedling) stem during feeding and not feeding activities. Ten visual records were taken per day, each spaced one hour during 30 days of 10 adult bugs of similar age exposed to maize seedlings inside cages (plastic tubes). At each observation, it was recorded if the bug was feeding on the stem (i.e., stylets inserted into the plant tissue) or not, and its body position. During feeding, waveforms were recorded using the EPG (electropenetrography) technique, which were correlated with histological studies to reveal the feeding sites. Results indicated that when they were feeding, the majority of the bugs were in the downward position. In contrast, when the bugs were on the plants, and not feeding, they were mostly in the upward position. Waveforms generated using the EPG coupled with histological studies demonstrated that during ingestion bugs fed from the xylem vessels and from the parenchyma tissue using cell rupture strategy in the latter. No clear explanation was found to explain the preferred downward body position during ingestion, but some hypothesis are speculated.

“…Thus, our work is the basis for the conduction of similar studies with other stink bug species that feed on rice crop, including researches with new Pentatomidae species that have recently been reported in this region on upland rice Foerster, 2017b;Grazia, 2015). Furthermore, studies should be conducted, for example, to check whether the Oebalus nymphs can cause the same damage as the adults, and also whether males and females cause similar damage, as studied in other species Olson, 2007;.…”

Index terms: Oryza sativa; stink bug of panicles; damage level; integrated pest management. RESUMOOebalus poecilus (Dallas 1851) é uma das espécies de percevejos de grande importância econômica para os produtores de arroz no Brasil em sistemas de cultivo irrigados, de inundação ou de terras altas. Estes pentatomídeos são conhecidos como percevejos das panículas, porque ninfas e adultos alimentam-se principalmente dessas estruturas. O ataque deste percevejo resulta em grãos manchados, massa inferior, redução germinativa e grãos deformados. Considerando isso, o objetivo deste estudo foi avaliar as perdas quantitativas e qualitativas na cultivar comercial de arroz de terras altas (variedade Cambará), submetidas a diferentes níveis de infestação de percevejos de panículas, O. poecilus, em diferentes estágios de crescimento reprodutivo das plantas de arroz. Os resultados mostram que em arroz de terras altas (variedade Cambará), os grãos de arroz são suscetíveis a danos quantitativos (número e peso) e qualitativos (grãos manchados, atrofiados, gessados e quebrados), durante todo o desenvolvimento da panícula. No entanto, quando os insetos se alimentam durante os estágios de antese/cariopse e leitosa causam percentual significativamente maior de grãos vazios (até 83%) do que quando se alimentam de grãos durante as fases posteriores do desenvolvimento da panícula. Esta característica foi também observada para a redução de peso dos grãos. Esta informação pode beneficiar os produtores e outros pesquisadores, permitindo que concentrem os esforços de monitoramento de O. poecilus em fases mais suscetíveis ao ataque deste inseto. Também serve de base para a tomada de decisão sobre quando e quais medidas de controle devem ser realizadas, a fim de controlar os percevejos das panículas.Termos para indexação: Oryza sativa; percevejo das panículas; nível de dano; manejo integrado de pragas.

“…Field and semi-field studies must be conducted to assess whether the same pattern of results obtained in laboratory studies is maintained in the field, both for A. gemmatalis and for other insects and food crops (Albuquerque, 1993;Krinski & Pelissari, 2012;Krinski, Favetti, & Butnariu, 2012;Favetti, Krinski, & Butnariu, 2013;Krinski, 2013;Krinski, 2015;Krinski & Godoy, 2015;Krinski, Foerster, & Grazia, 2015;Krinski & Foerster, 2017;Martins & Krinski, 2016).…”

ABSTRACT. The toxicities of essential oils (EOs) from 18 species of Brazilian Piperaceae were assessed on eggs of the velvetbean caterpillar, Anticarsia gemmatalis. Oils were extracted using steam distillation, and dilutions were made for bioassays at concentrations of 0.25, 0.5, 1.0, 2.0, and 4.0%. All EOs reduced larval hatching. The lowest lethal concentrations were obtained from Piper fuligineum (SP), Piper mollicomum "chemotype 1" (SP), Piper mosenii (PR), Piper aduncum (PA) and Piper marginatum (PA). Ovicidal activity is related to the potential toxicity of several compounds, especially dilapiolle, myristicin, asaricine, spathulenol and piperitone. According to our results, EOs from 16 Brazilian Piper species have potential for use as biorational botanical insecticides.
