摘要： Riptortus pedestris is one of the most destructive pests of leguminous crops in East Asia. In this study, we assessed the effect of different leguminous plant species, including soybean, wild soybean, white kidney bean, runner bean, pea, cowpea, adzuki bean, mung bean, faba bean, and lentil vetch, on the development and reproduction of R. pedestris. We found that leguminous plant species significantly affect the developmental duration and survivability of the nymphs, adult longevity, and oviposition and fecundity in R. pedestris. The nymphs completed their development on all of these plants. The developmental duration of nymphs was the shortest (16.24 +/- 0.57 days) on soybean and the longest (31.33 +/- 1.76 days) on faba bean. The rates of survival of nymphs on soybean and pea were 93.2% and 93.0%, respectively. Female adults survived the longest on soybean (64.67 +/- 6.64 days) and the shortest (13.27 +/- 3.67 days) on white kidney bean. The fecundity on faba bean (decorticated pods) (143.0 +/- 28.04 eggs) and soybean (116.63 +/- 12.76 eggs) was higher than those on other plants. The age-specific life table revealed that the population trend index values were all >1 except on wild soybean and faba bean, and the highest was on soybean (30.36), followed by pea (21.0). Soybean and pea were identified as the most suitable hosts for R. pedestris because of their shorter developmental duration, higher survivability, longevity and fecundity and greater population trend index on these hosts, while wild soybean and faba bean were relatively unsuitable host plants.
