Differential Consumption Of Four Aphid Species By Four Lady Beetle Species, Christy Finlayson, Andrei Alyokhin, Serena Gross, Erin Porter

The acceptability of four different aphid species Macrosiphum albifrons (Essig), Macrosiphum euphorbiae (Thomas), Macrosiphum pseudorosae Patch, and Myzus persicae (Sulzer) (Hemiptera: Aphididae), as prey for four lady beetle species, one native species Coccinella trifasciata L, and three non-native Coccinella septempunctata L, Harmonia axyridis Pallas, Propylea quatuordecimpunctata L (Coleoptera: Coccinellidae) were tested in the laboratory. The relative field abundance of adults of the same lady beetle species on host vegetation, Lupinus polyphyllus Lindley (Fabales: Fabaceae), Solanum tuberosum L (Solanales: Solanaceae), and Rosa multiflora Thunberg (Rosales: Rosaceae), both with and without aphids present was also observed. In the laboratory, H. axyridis generally …

The Evaluation Of Conservation Practice Placement In The Little River Experimental Watershed Using Geographic Information Systems, J Settimi, Dana Sullivan, Timothy Strickland

The Conservation Effects Assessment Program Watershed Assessment Study is a joint effort between the USDA Natural Resources Conservation Service (NRCS) and the USDA Agricultural Research Service to evaluate the effectiveness of federally funded conservation programs. In response to this initiative, a 26-year history of NRCS conservation practice placement (1980 to 2006) was evaluated for the Little River Experimental Watershed (LREW) in the southeastern coastal plain of Georgia. To accomplish this task, currently available geographic databases were integrated and queried to assess levels of commonly adopted practices and to evaluate factors affecting practice placement. Databases included (1) USDA NRCS Conservation Practice …

As conservationists well know, political borders rarely coincide with natural ecological boundaries. International borders such as that between the United States and Mexico traverse numerous ecosystems and watersheds. Many species of animals, birds, and insects regularly migrate between habitats across international borders. Conservation of Shared Environments collects works that take on the environmental issues along the U.S.-Mexico border. Covering topics as diverse as wildlife preservation, grassland ecology, water rights, indigenous peoples, and the ecological consequences of border security, the contributors to this volume offer not only scientific analysis but also insight on how to bridge the gaps between scientists, policy …

Colorado Potato Beetle Resistance To Insecticides, Andrei Alyokhin, Mitchell Baker, David Mota-Sanchez, Galen Dively, Edward Grafius

The Colorado potato beetle, Leptinotarsa decemlineata (Say), is widely regarded as the most important insect defoliator of potatoes. Its current range covers about 16 million km2 in North America, Europe, and Asia and continues to expand. This insect has a complicated and diverse life history, which is well-suited to agricultural environments, and makes it a complex and challenging pest to control. Dispersal, closely connected with diapause, feeding, and reproduction, allow the Colorado potato beetle to employ "bet-hedging" reproductive strategies, distributing its offspring in both space (within and between fields) and time (within and between years). The Colorado potato beetle played …
Volatile Compounds On The Leaf Surface Of Intact And Regrowth Tarbush (Flourensia Cernua Dc) Canopies, Ed Frederickson, R. Estell, M. Remmenga
Volatile Compounds On The Leaf Surface Of Intact And Regrowth Tarbush (Flourensia Cernua Dc) Canopies, Ed Frederickson, R. Estell, M. Remmenga
Ed L. Frederickson
Shrub expansion into desert grasslands is a serious problem resulting in loss of forage and rangeland productivity. Flourensia cernua DC (tarbush) is one such shrub contributing to the decline of Chihuahuan Desert grasslands. Our previous research has shown tarbush consumption by sheep and goats to be negatively related to leaf surface concentration of individual terpenes and epicuticular wax. Concentrations of compounds such as terpenes often change with plant age and phenology. Our objective was to examine the effect of altering the vegetative state of tarbush on volatile chemicals. Ninety tarbush plants were randomly selected, and all biomass within 10 cm …

Identifying The Core Periodical Literature Of The Agricultural Communications Documentation Center, Joseph Zumalt
Joseph R. Zumalt
Agricultural communications" is an emerging field which is naturally both part of the "agriculture" and "communications" literature. However, it is much broader than just a subset of each. The coverage of standard databases such as CAB Abstracts and Communication Abstracts, while a good start, does not sufficiently cover the field. The Agricultural Communications Documentation Center (ACDC) at the University of Illinois at Urbana-Champaign has, over the last quarter century, worked to help define and collect this literature, by identifying relevant documents and entering them into a Web-searchable Microsoft Access database. An analysis of this database reveals important clues concerning the …

Susceptibility Of Imidacloprid-Resistant Colorado Potato Beetles To Non-Neonicotinoid Insecticides In The Laboratory And Field Trials., Andrei Alyokhin, Galen Dively, Megan Patterson, David Rogers, John Wollam

Repeated use of neonicotinoid insecticides has resulted in the first reported cases of Colorado potato beetle (Leptinotarsa decemlineata (Say)) resistance to imidacloprid. In the laboratory we determined susceptibility of the imidacloprid-resistant Colorado potato beetles from a population in Southern Maine to other insecticides currently registered for use on potato. This population was about 30-fold resistant to imidacloprid and could not be effectively controlled by its applications. Control mortality was significantly higher for the imidacloprid-resistant larvae than for the susceptible larvae, suggesting that fitness disadvantages may be associated with the resistance trait. Resistant larvae exhibited significantly less mortality than susceptible larvae …

The effects of supplementation with mixed fodder or concentrate were investigated on the performance of a) growth of male lambs;md kids grazing extensively under oil palm trees and b) reproduction of ewes and goats stall-fed with native herbage. Supplemented kids and lambs had higher average daily weight gain than controls but the effect was only significant for those which received concentrate (p < 0.05). Final body weight was only significantly different from controls for lambs supplemented with concentrate (p < 0.05). The ages at puberty, first mating, first conception and first kidding of supplemented goats were about 110 days earlier than those for controls (p < 0.05 or better). Supplemented goats had first mating and conceived at lower body weights (p < 0.01) than those in control groups. Different feeding regimes had no effects (p > 0.05) on the reproductive performance of ewes apart fi om highest body weight of first lambing in animals supplemented with concentrate (p < 0.05). Native herbage available under oil palm trees of 5 years old was sufficient for growth …
