“…The attack of this stink bug affects the development of the plant, and makes it less vigorous, resulting in a reduced plant height and number of developed leaves. This impact can compromise the root system and normal development of the plant, resulting in negative results in grain productivity (Roza-Gomez et al, 2011;Crosariol Netto et al, 2015;Bridi et al, 2016).…”

The damage caused by insect pests in plants can considerably affect their development and crop yield. It can also cause the activation of biochemical defense mechanisms in the plant, combined with the production of reactive oxygen species. The levels of these oxygen molecules are controlled by antioxidant enzymes and this mechanism is an important plant defense process. The aim of this study is to learn the effect of feeding by the stink bug, Diceraeus melacanthus, on the growth of corn plants and on the activity of the antioxidant enzyme peroxidase (POD) and catalase (CAT). The study was carried out in a greenhouse, in a completely randomized design, with a 2 × 4 factorial block and five replications. The first factor was composed of plants with and without the presence of the bug and the second factor was composed the age of corn plants, two, four, six, and eight days after emergence. Corn seedlings infested with the stink bug were negatively influenced in terms of plant height, root mass and increasing in activity of the POD enzyme was 84% higher in plants infested at 8th DAE. The CAT enzyme activity was not detected in the samples. The stink bug feeding affected the growth of the corn seedlings. The analysis of the POD enzyme could be a valuable tool to quantify the stress caused by the stink bug in futures studies.

El maíz transgénico que expresa la toxina de Bacillus thuringiensis (Bt) produce un cristal (Cry) de proteína tóxica para las orugas de las hojas y los tallos de maíz Bt, pero es atóxica para chinches. Los objetivos de este estudio fueron identificar la cantidad de plantas de maíz atacadas y no por la chinche barriga verde Dichelops melacanthus, evaluar los daños foliares a través del número de punturas, la altura de plantas y la producción en peso de granos de las plantas de maíz atacadas y no. La investigación se realizó en una granja agrícola de producción comercial en una superficie de 700 m2. Los datos fueron registrados en hoja impresa, tabulada en planilla electrónica Excel y analizados estadísticamente por el test T-Student con una significancia del 5 % para comparación de dos grupos de muestras independientes. Los resultados obtenidos indican que el 80,7 % de las plantas de maíz fueron atacadas por la chinche D. melacanthus presentando punturas foliares. La altura promedio de las plantas atacadas fue de 41,2 ± 2,2 cm y 41,5 ± 3,3 cm de las no atacadas. En relación a la producción se ha verificado una reducción significativa del 23 %. El peso de los granos de maíz por planta atacada tuvo un promedio de 3,048 ± 199 g y 3,956 ± 269 g en planta no atacada, demostrando así que los daños ocasionados por D. melacanthus reducen el rendimiento del maíz Bt.

“…soybean, infestation is concentrated in the reproductive stages (Silva et al, 2013); while in some Poaceae, such as corn and wheat, infestation and damage occurs in the seedling stage as a result of migrating adults from surrounding crop debris or other plants within the field (Torres et al, 2013;Smaniotto and Panizzi, 2015;Chiesa et al, 2016). Damage to seedling corn causes brown spots, leaf discoloration and twisting, reduced yield (Crossariol Netto et al, 2015), or plant death (Roza-Gomes et al, 2011;Torres et al, 2013). In order to avoid yield loss in corn, neonicotinoid seed treatment is common (Martins et al, 2009;Brustolin et al, 2011;Crossariol-Neto et al, 2015;Chiesa et al, 2016).…”

“…Some authors describe D. melacanthus as a member of the subgenus Neodichelops (Grazia, 1978); while other authors include it in the subgenus Diceraeus (Rider, 2015). In spite of the variation in the nomenclature adopted, most of previous work treated it as D. melacanthus (Marques et al, 2007;Panizzi et al, 2007;Chocorosqui and Panizzi, 2008;Roza-Gomes et al, 2011;Silva et al, 2013;Torres et al, 2013;Crossariol Netto et al, 2015;Dellapé et al, 2015;Smaniotto and Panizzi, 2015;Bortolotto et al, 2016;Chiesa et al, 2016), and hence, this is the nomenclature that will be used throughout this manuscript. Dichelops melacanthus is polyphagous, infesting 29 species of 10 botanical families, among which are crops such as rice, corn, soybean, sorghum, wheat, and various weeds (Panizzi et al, 2007;Chocorosqui and Panizzi, 2008;Smaniotto and Panizzi, 2015;Bortolotto et al, 2016).…”

We determined the susceptibility of vegetative corn stages to Dichelops melacanthus damage, and how seed treatment can reduce damage and yield loss. Two field trials were carried out. In the first, corn plants were artificially infested with D. melacanthus male/female pairs at rate of 0.5 pair per plant at different vegetative stages and infestation periods lasting 7-28 days (V1-V3, V1-V5, V1-V7, V1-V9, V3-V5, V3-V7, V3-V9, V5-V7, V5-V9, and V7-V9), plus a control without infestation. In the second, corn plants were artificially infested at a rate of one male/female pair per plant at different vegetative stages and infestation periods (V1-V3, V1-V5, V1-V7, V3-V5, V3-V7 and V5-V7) and treated with two pesticide seed coatings: (i) fungicide [carbendazim + thiram (150 g i.a. per L and 350 g i.a. per L)] + insecticide [clothianidin (600 g i.a. per L)] or (ii) only fungicide (carbendazim + thiram), plus three controls without infestation and with only fungicide-treatment (V1-V7, V3-V7 and V5-V7). In both trials, plants were caged during the entire period in order to hold stink bugs in contact with plants and to avoid injury from other arthropods. The most stink bug susceptible corn growth periods were from V1-V5 and from V1-V7. Seed treatment with clothianidin at the rate of 3.5 mL per Kg during the most susceptible infestation periods increased yield gain of 37.8 to 61%. Treatment with clothianidin during V1-V5 and V1-V7 caused 40% to 50% D. melacanthus adult mortality, respectively.
