Currently, the invasive brown marmorated stink bug, Halyomorpha halys (Stal) (Hemiptera: Pentatomidae), is considered an agricultural and nuisance pest in Georgia. The invasive chinaberry tree, Melia azedarach L. (Meliaceae), commonly grows in dense thickets along roadsides, and in woodlands adjacent to agricultural crops across the southeastern USA. Thus, the objective of this study was to determine the potential of M. azedarach to serve as a host plant of H. halys by examining mortality and feeding of first and second instars on M. azedarach leaves vs. carrot (i.e., a control diet), and documenting presence of H. halys on M. azedarach in woodlands at 2 locations in Georgia where this stink bug has become established. Over all sampling dates and locations, the number of H. halys in chinaberry was very low (0.1 per tree), and only 3 late instars and 1 adult were observed feeding on M. azedarach at 1 field site late in the season. Percentage feeding by second instars of H. halys was lower for individuals given M. azedarach leaves vs. those provided with carrot, most likely indicating that compounds in M. azedarach have an antifeeding effect. In fact, mortality for second instars on M. azedarach leaves was very high, and thus we conclude that M. azedarach is an unsuitable host plant for H. halys. Key Words: brown marmorated stink bug; chinaberry; antifeedant Actualmente, se considera el chinche invasor hediondo marmorino cafe, Halyomorpha halys (Stal) (Hemiptera: Pentatomidae), como una plaga agricola y molesta en el estado de Georgia. El arbol de melio invasor, Melia azedarach L. (Meliaceae), comunmente crece en matorrales densos a lo largo de los caminos y en los bosques adyacentes a cultivos agricolas en todo el sureste de los EE. UU. Por lo tanto, el objetivo de este estudio fue determinar el potencial de M. azedarach para servir como una planta hospedera de H. halys mediante el examen de la mortalidad y la alimentacion del primer y segundo estadios de H. halys sobre hojas de M. azedarach vs. zanahoria (una dieta de control) y documentando la presencia de H. halys sobre M. azedarach en bosques en 2 ubicaciones en Georgia donde se ha establecido este chinche hedionda. En todas las fechas y ubicaciones de muestreo, el numero de H. halys sobre melio fue muy bajo (0,1 por arbol), y solo se observaron 3 estadios tardios y 1 adulto alimentandose de M. azedarach en 1 sitio de campo al final de la temporada. El porcentaje de alimentacion en los segundos estadios de H. halys fue mas bajo para los individuos que recibieron hojas de M. azedarach en comparacion con los que recibieron zanahoria, lo que probablemente indica que los compuestos en M. azedarach tienen un efecto antiagenico. De hecho, la mortalidad por segundos estadios en hojas de M. azedarach fue muy alta, y por lo tanto concluimos que M. azedarach es una planta hospedera inadecuada para H. halys. Palabras Clave: chinche hediondo marmorino cafe; melio; anti-alimentacion

Pest suppression through biological control seeks to maximize the action of the pest's natural enemies with the goal of reducing pesticide use. We present a summary of published studies and original findings on several entomophagous species as biocontrol agents of Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), a key pest of tomato crops in Argentina, with the aim to select potential candidates for its management. Spontaneously occurring T. absoluta egg parasitism was lower than that inflicted by the larval parasitoids Dineulophus phthorimaeae (De Santis, 1983) (Hymenoptera: Eulophidae) and Pseudapanteles dignus (Muesebeck, 1938) (Hymenoptera: Braconidae). These parasitoids exhibit important life history traits in laboratory conditions and produce relevant amounts of T. absoluta mortality in the field. Surveys carried out in Tucuman and Buenos Aires provinces, Argentina, revealed that D. phthorimaeae and P dignus coexist in tomato and eggplant crops; T. absoluta-P. dignus interaction is also found on other non-cultivated solanaceous species present in horticultural farms. In addition, studies are currently under way to determine the predation ability of Zelus obscuridorsis (Stal, 1860) (Hemiptera: Reduviidae) on both larvae and adults of the pest. Finally, we discuss the prospects for implementing experimental augmentative releases of P. dignus to control the pest, a candidate selected considering various positive biological traits and because of its simple mass production and manipulation compared with other antagonists of T. absoluta. Key Words: biocontrol, Lycopersicon esculentum L., Dineulophus phthorimaeae, parasitoid, predator, South American tomato leafminer El control biologico de plagas tiene como premisa maximizar la accion de sus enemigos naturales para reducir el uso de plaguicidas en la agricultura. En este trabajo se reune informacion de estudios sobre las especies de entomofagos de Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) mas importantes en el cultivo de tomate de la Argentina, con el objetivo de seleccionar candidatos potenciales para el control de esta plaga. Comparativamente, el parasitismo natural de huevos de T. absoluta es mas bajo que el provocado por los parasitoides larvales Dineulophus phthorimaeae (de Santis, 1983) (Hymenoptera: Eulophidae) y Pseudapanteles dignus (Muesebeck, 1938) (Hymenoptera: Braconidae). Estos parasitoides exhiben atributos relevantes como agentes de control en estudios de laboratorio y campo. Muestreos realizados en las provincias de Tucuman y Buenos Aires, Argentina, mostraron que D. phthorimaeae y P dignus coexisten en los cultivos de tomate y de berenjena, y tambien P dignus se encuentra en otras solanaceas no cultivadas presentes en los predios horti'colas. Adicionalmente, se estan llevando a cabo estudios para determinar la capacidad de depredacion de Zelus obscuridorsis (Stal, 1860) (Hemiptera: Reduviidae) sobre larvas y adultos de la plaga. Finalmente, se discute sobre la implementacion de liberaciones aumentativas de P dignus, candidato que reune varios atributos biologicos positivos como potencial agente de control biologico de la plaga, y cuya cria masiva y manipulacion son mas simples que las de otros antagonistas. Palabras Clave: biocontrol, Lycopersicon esculentum L., parasitoide, Dineulophus phthorimaeae, depredador, 'polilla del tomate'

- Abstract

The rice stalk stink bug, Tibraca limbativentris Stal (Hemiptera: Pentatomidae), is a major pest of rice crops throughout Latin America. We investigated the occurrence of diapause in T. limbativentris, as well as the role of West Indian foxtail, Andropogon bicornis L.(Poaceae), in its seasonal abundance and mortality. This plant grows spontaneously in grasslands from Mexico to Argentina, including at the edges of rice fields in southern Brazil. Tussocks of A. bicornis were collected in Eldorado do Sul, State of Rio Grande do Sul, Brazil throughout one yr and examined to sample rice stalk stink bugs. We collected in 2,355 T. limbativentris adults from 208 tussocks, totalling 2,205 live and 150 dead individuals. Live insects were dissected to determine the reproductive stage and to assess the presence of the fat body. We describe the occurrence of imaginal diapause and the use of A. bicornis as a shelter for this rice pest. Overwintering lasted 7 mo; arrival at the refuge occurred in early autumn (late Mar); the permanence period began in Jun, and extended to the end of Sep. From Oct the population decreased gradually until total departure from the tussocks in Jan. Thus, here we highlight the role of A. bicornis as an hibernation site for T. limbativentris in southern Brazil. Key Words: Diapause, rice stalk stink bug, subtropics, tussocks O percevejo-do-colmo do arroz, Tibraca limbativentris Stal (Hemiptera: Pentatomidae), e considerada uma das principais pragas do arroz irrigado na America Latina. A ocorrencia de diapausa em T. limbativentris foi investigada, bem como o papel do capim-rabo-de-burro, Andropogon bicornis L.(Poaceae), na abundancia sazonal e mortalidade. Esta planta cresce espontaneamente em pastagens do Mexico a Argentina, incluindo o entorno do cultivo de arroz no sul do Brasil. Touceiras de A. bicornis foram coletadas em Eldorado do Sul, Estado do Rio Grande do Sul, Brasil, durante um ano e examinadas para a amostragem os percevejos. Foram coletados 2.355 adultos de T. limbativentris provenientes de 208 touceiras, totalizando 2.205 individuos vivos e 150 mortos. Insetos vivos foram dissecados afim de determinar o estagio de desenvolvimento dos orgaos reprodutivos e avaliar a presenca de corpos gordurosos. A ocorrencia de diapausa imaginal e a utilizacao de A. bicornis como abrigo foram descritas. A hibernacao durou 7 meses: a entrada no refugio ocorreu no inicio do outono; o periodo de permanencia iniciou em Junho, e estendeu-se ate o final de Setembro. A partir de Outubro, a populacao decresceu gradualmente ate o abandono total das touceiras em Janeiro. Desta forma, destacamos o papel de A. bicornis como um sitio de hibernacao para T. limbativentris, no sul do Brasil. Palavras-Chave: Diapausa, percevejo-do-grao-do-arroz, subtropico, touceiras
