BackgroundThe most common pentatomid species in soybean crops are Euschistus heros (F.), Piezodorus guildinii (W.), and Diceraeus melacanthus (D.), causing a significant reduction in yield. It is known that these stink bugs inhabit the reproductive structures of soybeans simultaneously; however, there are few studies addressing their intraguild interactions, as well as aspects of possible competition between them in plants. Thus, the inter‐ and intraspecific interactions of these stink bugs were evaluated in laboratory and field conditions, throughout the duration of the instars and adulthood, including longevity, mortality, and the number of eggs per female.ResultsE. heros had a higher competitive capacity in the interaction with D. melacanthus and P. guildinii, negatively interfering in the abundance or development (duration of instar, fertility, and mortality) of these stink bugs in soybean crops. This interference may act on the natural balance of these insect pests. Mortality of adults in interactions containing E. heros as a competitor or not showed that this species was not affected by the other species under field conditions. In the scenario where D. melacanthus was evaluated, it was observed that the presence of other species caused higher mortality in D. melacanthus. Additionally, higher P. guildiniii mortality was observed in interspecific interactions.ConclusionOur results suggest that E. heros has a greater competitive ability in the soybean crop, followed by D. melacanthus and P. guildinii. Therefore, the results found justify the greater abundance of E. heros and help to explain the increasing occurrence of D. melacanthus in soybean crops, contributing to new directions for understanding the interaction of the soybean stink bug complex.This article is protected by copyright.

“…Despite the high damage potential of the stink bug to corn, the insect does not normally complete its cycle in this crop (Chocorosqui & Panizzi, 2008;Silva et al, 2013). Studies have shown that soybean allows the full development and reproduction of the stink bug, with a high population increase in the culture (Smaniotto & Panizzi, 2015;Canassa et al, 2017), providing a large number of insects to attack the off-season corn crop, which is grown in succession to soybean.…”

“…To allow an adequate aeration within the breeding cages, the lids were trimmed to the center and the aperture was covered with voile fabric. Whenever necessary, the food was replenished, the filter paper exchanged, and the cotton moistened in water (Canassa et al, 2017). The eggs of the stink bug were removed daily and packed in new breeding cages containing only a portion of moist cotton.…”

Abstract: The objective of this work was to evaluate the potential damage of the green-belly stink bug, Dichelops melacanthus, to corn in greenhouse and field conditions. Three trials were carried out. In the greenhouse, corn plants in the V1 stage were evaluated after each of them was infested with one insect in four developmental stages (nymphs of the third, fourth, and fifth instars and adults) during 14 days. In the field, corn plants in four developmental stages (V1, V3, V5, and V7) were infested inside cages with five adult stink bugs, also during 14 days. In another trial in the greenhouse, the same treatments of the field trial were conducted during 14 days, but with an infestation intensity of one bug per plant per pot. The control treatment was without infestation. In all trials, damage scores were attributed to the corn plants and the dry matter of the aerial part of the plants was determined. In the field, stem diameter and grain yield were also evaluated. Third-instar nymphs do not cause significant changes in the dry weight of the aerial part of the plant and in the damage scores, compared with the control treatment. Infestations by adult stink bugs cause more damage to corn plants in the V1 and V3 stages, both in field and greenhouse conditions.

“…A seleção de genótipos com caracteres relacionados à tolerância a estresses bióticos têm sido objeto de interesse em programas de melhoramento, principalmente, em virtude da ineficiência da seleção para caracteres quantitativos, em condições adversas e em virtude da alta vulnerabilidade, para esses caracteres que incorrem as grandes culturas. Além disso, o uso de cultivares resistentes é o meio mais econômico e sustentável de combate a doenças (SMITH; CLEMENT, 2012;CANASSA et al, 2017).…”

A soja (Glycine max L.) é um dos produtos agrícolas mais importantes para o Brasil, além disso, é uma rica fonte de proteína e óleo para nutrição humana. A produtividade das plantas de soja pode ser severamente prejudicada pelo inseto Helicoverpa armigera, que foi oficialmente detectado, no Brasil, durante a safra 2012/2013. A principal estratégia de gerenciamento para essa praga é o controle químico e plantas Bt. No entanto, métodos menos agressivos devem ser incorporados para o manejo sustentável, como a obtenção de genótipos resistentes. Nesse sentido, o presente trabalho consiste em uma pesquisa bibliográfica sobre os estudos de melhoramento genético de soja que visem à obtenção de genótipos resistentes à H. armigera. Para tanto, foram selecionados artigos nacionais e internacionais que abordassem o tema. Conforme os dados obtidos, as cultivares BP, M4, Sahar, JK, L17, Gorgan3, PI 227687, PI 274453, PI 274454, PI 229358, PI 171451, IAC 17 e IAC 19 apresentam resistência à H. armigera e poderão ser incorporadas aos programas de melhoramento brasileiro. De modo geral, acredita-se que esta pesquisa servirá como material de referência para apoiar pesquisadores na condução de estudos futuros que visem ao melhoramento de soja.
