Laboratory studies were conducted with the Neotropical brown stink bug, Euschistus heros (F.), to evaluate nymphal and adult biology on immature pods of soybean, Glycine max (L.) Merrill (Fabaceae), bearing the block technology (resistant to stink bug damage ? cvs. BRS 391, BRS 543 RR and BRS 1003 IPRO) compared to a susceptible cultivar (BRS 5601 RR). Results indicated that nymphs? developmental time and survivorship were similar on all cultivars tested. The same was observed for adult survivorship and reproductive performance. However, data from electropenetrography (EPG) demonstrated that adults of E. heros spent significantly less time in feeding activities on resistant plants compared to the susceptible one. Large differences were observed in feeding activities on seeds; on resistant plants, the insects dedicated a shorter period of time to feed on seed endosperm than on BRS 5601. In addition, when bugs fed on seeds of block cultivars, the majority of probes were composed of only laceration/maceration activities (Eh3a waveform) without ingestion events of the cell contents (Eh3b waveform). In contrast, on the susceptible cultivar, Eh3a waveform events were repeated much more frequently (3-5X) with more probes also containing ingestion of seed contents. These results suggest that the soybean cultivars bearing the block technology presented a lower preference (antixenosis) by the bugs with fewer feeding activities, primarily in the seed endosperm, compared to the susceptible one tested.
