Sampling grids for monitoring Euschistus heros infestation in soybean [PDF]
ABSTRACT Euschistus heros is one the most important pest insect in soybean fields in Brazil. Therefore, site-specific management applied for controlling E. heros can result in economic and environmental benefits. However, sampling protocols for assessing spatialtemporal variability of this soybean pest and, then, for guiding a more sustainable pest ...

Release strategies of Telenomus podisi for control of Euschistus heros: a computational modeling approach [PDF]
AbstractBACKGROUNDThe egg‐parasitoid wasp Telenomus podisi has received attention as a biological‐control agent for one of the most important soybean pests in Brazil, the stink bug Euschistus heros. As yet, no studies have conclusively established strategies for the release of T. podisi. We developed a computational model using cellular automata in the

Vertical Distribution of Euschistus heros in the Leaf Canopy of Soybean Plants
The occurrence of phytophagous stink bugs in soybeans can result in production losses, if this pest is not properly controlled. Our objective was to study the vertical distribution (intra-plant) of nymphs and adults of Euschistus heros (Fabricius, 1798) (Hemiptera: Pentatomidae) in the leaf canopy of soybean plants, during the day.

Stink Bug Population in Cotton Plantations with Different Plant Spacings
The increase in cotton plant population by decreasing the spacing between rows cause some changes in phenotypical characteristics of cotton plants, such as decrease in number of leaves per plant, low-development leaves, and great soil shading. Stink bugs
