“…Hemipterans preferentially feed on young, tender growth and developing seeds (growth stages R4-R6 in soybean) [16, 17], but peak infestation of stink bugs in soybean fields generally occurs at the mid to late pod filling stage (stages R5-R7) [16, 18, 19, 20, 21]. However, Kim and Lim [22] and our preliminary observations found R .…”

Riptortus pedestris (Fabricius) and Halyomorpha halys (Stål) cause injury to soybeans by piercing and sucking pods and seeds. Growers believe that new damage decreases near to harvest despite the occurrence of these bugs at that time. As this question has never been assessed, we evaluated two diets: a) mature soybean pods (dried shell + dried soybean seeds) and b) dried soybean seeds for the two bugs by assessing their biological, behavioral, and morphological attributes on each diet in laboratory. While nymphs of both species were able to develop and adults able to reproduce on the tested diets, bugs fed on pods had longer development times and 2.2 to 5.0 times higher mortality rates than bugs fed on seeds. Furthermore, adult longevity of R. pedestris and H. halys fed on pods was 8.4 and 7.5 days shorter, respectively, than that of bugs fed on seeds. However, pod feeding had no effect on adult fecundity or egg viability. In a behavioral choice test, adult R. pedestris preferred seeds over pods and probed seeds longer than pods. On average, adult H. halys also preferred seeds over pods, although 15.6% of H. halys showed the reverse, preferring pods over seeds. The proboscis length and estimated depth of stylet penetration into the host tissue of both nymphs and adults of both species was much greater than the thickness of the pod shell, suggesting that mouthpart structure does not explain the negative effects of pods vs. seeds. In conclusion, mature soybean pods were found to be a suitable food source for both R. pedestris and H. halys despite some negative effects, and thus careful attention should be paid to the population levels of these two bugs approaching harvest to reduce economic damage in soybean.

“…Also, a shift in soybean production from May-planted maturity group (MG) V and VI in conventional soybean production systems to Aprilplanted MG III and IV in early season soybean production, may have contributed to stink bug population growth in recent years (Heatherly 2005). The increased pressure of stink bugs on early planted soybeans may be due to the early availability of pods (Baur et al 2000). After colonizing early-planted soy-beans, stink bugs successively move to later planted soybeans as the developing pods become available (Baur et al 2000).…”

“…Euschistus quadrator Rolston (Hemiptera: Pentatomidae) is a polyphagous stink bug that is recognized as a pest of soybean (Glycine max [L.] Merrill; Fabaceae) and cotton (Gossypium hirsutum L; Malvaceae ) Drees & Rice 1990;Baur et al 2000;Bundy & McPherson 2000a;Willrich et al 2003;Esquivel et al 2009;Ruberson et al 2009;Temple et al 2011Temple et al , 2013Parker 2012;Suh et al 2013;Tillman et al 2015). The species was first identified in 1974 with specimens collected in northern Mexico, the Yucatan Peninsula, Texas, and Louisiana (Rolston 1974).…”
