Chloris distichophyllaLag. (Poaceae) as stink bug (Pentatomidae) shelter in soybean and corn off-season in southern Brazil

“…Klein et al (2012) identified Andropogon bicornis L. (Poaceae) as a hibernacle of a series of stink bugs in off-season of rice crop. The same situation was observed by Pasini et al (2018), who also observed the occurrence of T. limbativentris in Andropogon lateralis (Poaceae).…”

“…Thus, its occupation was only for survival during the crop off-season. The same situation was observed in A. bicornis (Klein et al 2012, Pasini et al 2018, Engel et al 2018).…”

“…(Hemiptera: Pentatomidae). On the other hand, Pasini et al (2018) verified the dependence of the T. limbativentris bugs on host plants during the off-season in an irrigated rice field. In this context, the knowledge about the plants associated with these insects during the crop off-season becomes of extreme importance for integrated pest management.…”

“…Because of the large number of host and associated plants, the economic importance of stink bugs is related not only to their feeding behavior but also to their forms of survival (Smaniotto & Panizzi 2015, Pasini et al 2018. Their wide geographical distribution makes them pests not only in Brazil, but in the world, either in the form of invasive or endemic species (McPherson 2018).…”

“…The knowledge of the different forms of survival and plants associated with pentatomid bugs during the off-season allows the optimization of the management by identifying areas of control and infestation (Engel et al 2018). This work identified the diversity of a stink bug assembly associated with Chloris distichophylla located in the border of the cultivation area during the off-season of soybean and corn crops for five consecutive years.…”
