Interactions of selected species of stink bugs (Hemiptera: Heteroptera: Pentatomidae) from leguminous crops with plants in the Neotropics

Herein we discuss the interactions of selected species of phytophagous stink bug observed on leguminous (Fabaceae) crops in the Neotropics (Neotropical Region) with their associated plants. We included the following pentatomid species: Nezara viridula (L.), Piezodorus guildinii (Westwood), Euschistus heros (F.), Edessa meditabunda (F.), Dichelops furcatus (F.), Dichelops melacanthus (Dallas), and Thyanta perditor (F.). Based on a literature review, a list of plants on which these stink bug species were intercepted is included, indicating the reproductive hosts, i.e., plants on which bug can complete development, and incidental records, i.e., plants on which bugs are found occasionally. The change in feeding habits (from fruits/seeds of preferred host plants) to less preferred vegetative structures (stems/leaves of less preferred associated plants) for feeding or shelter, due to change in the landscape by intense multiple cropping and no-tillage cultivation systems is discussed.
Resumo
Nessa revisão são discutidas as interações das principais espécies de percevejos fitófagos (Hemiptera: Heteroptera: Pentatomidae) encontradas em leguminosas (Fabaceae) com plantas associadas na Região Neotropical. As seguintes espécies foram incluídas: Nezara viridula (L.), Piezodorus guildinii (Westwood), Euschistus heros (F.), Edessa meditabunda (F.), Dichelops furcatus (F.), Dichelops melacanthus (Dallas) e Thyanta perditor (F.). Com base em revisão de literatura, uma lista de plantas onde os percevejos foram interceptados é incluída, indicando os hospedeiros reprodutivos, i.e., plantas nas quais os percevejos completam o desenvolvimento, e records acidentais, i.e., plantas nas quais os percevejos são encontrados eventualmente. A troca de hábitos alimentares (dos frutos/sementes de plantas hospedeiras preferidas) para as estruturas vegetativas menos preferidas (ramos/folhas de plantas associadas menos preferidas) para alimentação ou abrigo, devido à troca no cenário agrícola ocasionada pelos cultivos múltiplos intensos e semeadura direta é discutida.
