Notes on the Biology and Hosts of Stelidota Ferruginea (Coleoptera:Nitidulidae)
Author: Jimmy R. Galford
Publisher:
ISBN:
Category : Beetles
Languages : en
Pages : 8
Book Description
S2The nitidulid Stelidota ferrugnea Reitter was reared from damaged acorns of laurel oak, Quercus laurifolia Michx., and live oak, Q. virginiana Mill., collected in Sarasota County, Florida. This sap beetle has been reared in the laboratory solely on northern red oak, Q. rubra, acorns for more than 3 years (27 + generations), and can breed in viable or nonviable acorns. In the laboratory, S. ferruginea can develop in the seeds of several tree species. New information on the biology of S. ferruginea is presented. S3.

Factors Affecting Recreation Participation by Vermont Residents
Author: Thomas A. More
Publisher:
ISBN:
Category : Recreational surveys
Languages : en
Pages : 522
Book Description
Long-term recreation planning requires an understanding of recreation participation patterns. This study examined Vermonters' participation in 27 leisure activities from three domains (outdoor, resource based, and indoor) to see how such participation differed in each domain. Indoor activities were the most popular, followed by resource-based activities and general outdoor activities. Overall participation declined with age, though this effect was mitigated somewhat for older parents. Other socioeconomic and demographic variables had limited effects on participation.

Response of Insects to Damaged and Undamaged Germinating Acorns

ISBN:
Category : Acorns
Languages : en
Pages : 8
Book Description
S2Damaged germinating northern red oak, Quercus rubra L., acorns in pitfall traps were significantly more attractive to two species of acorn insects than undamaged germinating acorns. Significantly more adults of the weevil Conotrachelus posticatus Boheman and the sap beetle Stelidota octomaculata (Say) were caught in traps containing germinating acorns cut into halves versus traps containing uncut, germinating acorns. Larvae of the acorn moth Valentinia glandulella (Riley) also preferred damaged over undamaged acorns, but few larvae were caught and the results were not analyzed. S3.

Stand Development and Yields of Appalachian Hardwood Stands Managed with Single-tree Selection for at Least 30 Years
Author: Neil I. Lamson
Publisher:
ISBN:
Category : Forests and forestry
Languages : en
Pages : 20
Book Description
S2Appalachian hardwood stands in West Virginia were managed for 30 or more years using single-tree selection regeneration practices. Stand yield data suggest that current stand growth will provide economical harvest cuts for several future cutting cycles. This case study indicates that single-tree selection has potential for landowners who want to maintain continuous overstory cover and are willing to accept the gradual species shift to more shade-tolerant species.S3.
