Distribution of Helicoverpa zea and Heliothis virescens (Lepidoptera: Noctuidae) across an agricultural landscape and implications to farm-level management

Clint Allen, and R. G. Luttrell, University of Arkansas, 319 Agri Building, Fayetteville, AR

Insect scouting records from a large production farm were used to examine the temporal and spatial distribution of Helicoverpa zea and Heliothis virescens in relation to various agricultural hosts. The influence of surrounding crop types on immature stages in cotton was examined. Although egg populations in cotton were not randomly distributed across the farm, the crop type surrounding a particular cotton field had little influence on these populations.

Species 1: Lepidoptera Noctuidae Helicoverpa zea (corn earworm, bollworm)
Species 2: Lepidoptera Noctuidae Heliothis virescens (tobacco budworm)
