Development of Dichelops furcatus (Hemiptera: Heteroptera: Pentatomidae) Reared on Spring Cereals Versus Soybean [PDF]

Journal of Insect Science, 2018
The performance and preferences of the stink bug, Dichelops furcatus (F.), for spring cereals (wheat, rye, triticale, oat, and barley) were compared in the laboratory to their preferred host crop, soybean pods. Nymphs took significantly less time to reach adulthood on soybean pods compared to those fed seed heads of the five spring cereals tested ...

Probing Behavior of Dichelops furcatus (F.) (Heteroptera: Pentatomidae) on Wheat Plants Characterized by Electropenetrography (EPG) and Histological Studies [PDF]

Journal of Insect Science, 2017
The stink bug Dichelops furcatus (F.) (Heteroptera: Pentatomidae) has increased in abundance in recent years on the wheat, Triticum aestivum L., crop cultivated in the southern region of Brazil. To investigate the probing (stylet penetration) behaviors and nonprobing behaviors of D.

Dinotefuran toxicity on predators and egg parasitoids of Piezodorus guildinii and Dichelops furcatus (Hemipetra: Pentatomidae) under field conditions

Pesquisa Agropecuária Tropical
Piezodorus guildinii and Dichelops furcatus stink bug populations are naturally regulated by predators and egg parasitoids. However, these natural enemies can be affected by the application of non-selective insecticides commonly employed for stink ...

Virulence of Metarhizium brunneum (Ascomycota: Hypocreales) Strains Against Stinkbugs Euschistus heros and Dichelops furcatus (Hemiptera: Pentatomidae)

Journal of Economic Entomology, 2020
AbstractThree strains of fungi belonging to the genus Metarhizium Sorokīn (ARSEF 4556, ARSEF 3297, native strain) were assayed against adults and nymphs of the Neotropical brown stinkbug Euschistus heros (F.) and the green-belly stinkbug Dichelops furcatus (F.). The most virulent strain, ARSEF 4556, caused over 90% mortality.

Effect of green-belly stink bug, Dichelops furcatus (F.) on wheat yield and development [PDF]

Crop Protection, 2016
Abstract The green belly stink bug, Dichelops furcatus (F.) (Hemiptera: Heteroptera: Pentatomidae) is a pest of corn and soybean in southern Brazil. It also occurs on wheat, but information on its damage to this crop is limited. To determine the need for sustainable IPM programs, the impact of this bug on wheat production should be determined ...

Electropenetrographic Comparison of Feeding Behavior of Dichelops furcatus (Hemiptera: Heteroptera: Pentatomidae) on Soybean and Spring Cereals

Journal of Economic Entomology, 2020
AbstractWe 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.

Populações de percevejos barriga-verde [Dichelops furcatus (Hemiptera: pentatomidae)] em diferentes diâmetros de plantas silvestres durante entressafra de soja e milho

Revista De Ciências Agrárias, 2017
Compreender as formas de sobrevivência dos insetos em períodos desfavoráveis e sua relação com plantas e suas respectivas estruturas morfológicas é fundamental para o manejo integrado de pragas. O trabalho teve por objetivo avaliar a densidade populacional de percevejos da espécie Dichelops furcatus em plantas de Andropogon bicornis e Erianthus ...
