Comparing growth patterns among field populations of cereal aphids reveals factors limiting their maximum abundance

Original language description

Cereal stands in central Europe are commonly infested with three species of aphids that may become serious pests. With increasing abundance, the proportion of a particular species in the total aphid population may remain constant, suggesting a density-independent exponential growth, or the proportion can change, suggesting density-dependent constraints on growth. The constraints that affect particular species, and thus their relative abundance, were studied. The proportionality between maximum abundances of the cereal aphids was studied using a 10-year census of the numbers of aphids infesting 268 winter wheat plots. For two species their abundance on leaves and ears was compared. With increasing aphid density the maximum abundance of Rhopalosiphum padi (Linnaeus) remained proportional, but not that of Sitobion avenae (Fabricius), which was constrained by the smaller surface area of ears compared to leaves. There was no evidence of inter-specific competition. Maximum abundance of R. pa

Faktory limitující růst populací obilních mšic

Czech description

Dlouhodobé údaje o populační dynamice tři druhů obilních mšic jdou hodnoceny z pohledu regulace jejich růstu hustotně závislými faktory. Tento přístup umožní zpřesnit modely sloužící k předvídání ekonomických prahů výskytu těchto škůdců.
