在代表仲夏（30 ℃）的温度和光照条件下，将迁移性马利筋虫Oncopeltus fasciatus的若虫发育的能量学与越冬的常驻马利筋虫Lygaeus kalmii的若虫发育的能量学进行比较。C，14[光]L：10[暗]D和初秋（20度）。C，12L：12D）。在乳草种子饮食，这两个物种生长迅速，在30 ℃。C（< 18天至终期蜕皮），这是由于它们的高同化效率（59- 93%）和非常高的净生产效率（90- 94%）。在20 ℃时，两个物种的发育明显减慢。C（最多28天至终期蜕皮），但低温导致了更大的整体增长率下降。在30 ℃下测得的Kal mii值为52%。C，0。在30 ℃下测量的71%。C.某些特征的发展是一致的迁徙习惯：移民增长更快，比居民保持更高的同化效率，其季节性和更单食性的饮食;和移民保持高增长率在更广泛的温度范围内，从而使快速成熟的昆虫在炎热的仲夏条件和凉爽的秋季温度发生之前的迁移。
The energetics of nymphal development of a migratory milkweed bug, Oncopeltus fasciatus, were compared to those of an overwintering resident milkweed bug, Lygaeus kalmii, at temperature and light conditions representative of midsummer (30.degree. C, 14[light]L:10[dark]D and early autumn (20.degree. C, 12L:12D). On a milkweed seed diet, both species grew rapidly at 30.degree. C (< 18 days to teneral moult) due to their high assimilation efficiency, 59-93%, and very high net production efficiency, 90-94%. Development of both species was slowed markedly at 20.degree. C (up to 28 days to teneral molt), but low temperatures caused a greater reduction in the overall growth rate of L. kalmii nymphs, 52% of that measured at 30.degree. C, than of 0. fasciatus nymphs, 71% of that measured at 30.degree. C. Certain characteristics of development were consistent with a migratory habit: the migrant grew more rapidly than the resident by maintaining a higher assimilation efficiency on its seasonally available and more monophagous diet; and the migrant maintained a high growth rate over a broader temperature range thus allowing rapid maturation of nymphs in hot midsummer conditions and the cool fall temperatures occurring prior to migration.
