Seasonal Alterations in Host Range and Fidelity in the Polyphagous Mirid Bug, Apolygus lucorum (Heteroptera: Miridae)

摘要: In herbivorous insects, host plant switching is commonly observed and plays an important role in their annual life cycle. However, much remains to be learned about seasonal of various pestiferous arthropods under natural conditions. From 2006 until 2012, we assessed Apolygus lucorum (Meyer-Dur) use successive spring, summer winter seasons at one single location (Langfang, China). Data were used quantify changes breadth fidelity between seasons. Host A. differed seasons, with 87.9% spring hosts also the 36.1% winter. contrast, as little 25.6% species shared spring. Annual herbaceous plants are most often for overwintering, while perennial woody relatively initial population build-up Our study contributes improved understanding evolutionary interactions its lays groundwork design management strategies this pest myriad crops.
