- Title

- Abstract
Emergence patterns and sex ratios of the twig girdler, Oncideres cingulata (Say), were examined during 2004-2005 relative to measures of twig morphology and species of host tree. Emergence patterns varied significantly between study years, by sex, and among host species. Beetles emerged an average of 10 days earlier in 2004 than in 2005. Mean date of emergence for male beetles was 3 days earlier than for females. Beetles emerged from twigs girdled from honey locust (Gleditisia triacanthos L.) a day earlier than from American elm (Ulmus americana L.), 2 days earlier than from pecan (Carya illinoensis (Wangenh.) K. Koch), and 4 days earlier than from birch (Betula nigra L.). However, regression models found only weak relationships between twig morphology parameters and the timing of emergence of beetle adults. Similarly, sex ratios were unrelated to any aspect of twig morphology and did not vary between years or among host species.
