Distribution of western bean cutworm eggs among short-, mid-, and long-season corn hybrids planted on different dates
Environmental Entomology 12 (5), 1375-1379
Abstract: Oviposition rates of western bean cutworm, Loxagrotis albicosta (Smith) (Lepidoptera: Noctuidae), were determined throughout the ovipositional period for 3 years in three to five corn hybrids with different day-degree requirements, each planted on two to three dates. Number of eggs lard was found to be related to both factors. Overall, plots with the earliest mean growth stage tended to receive the greatest number of eggs at all sampling dates. In 1 year, oviposition began while growth stages were earlier than in the other 2 years. Egg distribution for that year showed a tendency for plants that were just beginning to tassel to receive more eggs than earlier or later growth stages. The relationships between adult light trap catches and total oviposition in the experimental area appeared similar in the 3 years regarding magnitude and timing of peak numbers and duration of activity.
