Phytophagous hemiterans (heteropterans) are polyphagous, feeding on a wide array of plants. These plants are important food resources for development of nymphs and reprodution of adults, and play an important role in the buildup of pest populations. To illustrate this, I will discuss the host plant sequence utilized in northern Parana state, Brazil, by three major pentatomids pests of soybean, which are: the southern green stink bug, Nezara viridula, the small green stink bug, Piezodorus guildinii, and the neotropical brown stink bug Euschistus heros. There bugs also feed on less preferred plants including several uncultivated-wild, and cultivated plants. On these plants they may change their feeding behavior, from a typical seed/fruit sucking habit, to leaf/stem feeding, with consequences to its nymphal and adult performance. In their life history, other strategies are used to overcome periods when food sources are scarce. For instance, E. heros, will pass 6 to 7 months underneath fallen dead leaves, without feeding, in a state of partial hibernation (diapause). The knowledgment of their life history is important to development managing strategies to avoid outbreaks on summer crops such as soybean. |
