Responses of males to a pheromone blend of female Oriental fruit moth with and without E8, E10-dodecadien-1-ol, a pheromone component of codling moth (Lepidoptera: Tortricidae)

Creator:: Allred, Darin B.
Abstract:: E8,E10-dodecadien-1-ol, the primary component of the female sex pheromone of codling moth, Cydia pomonella L., has no attraction to male Oriental fruit moth (OFM), C. molesta (Busck). However, this compound when added to the OFM pheromone blend of Z8-dodecenyl acetate (85.5%), E8-dodecenyl acetate (5.5%), and Z8- dodecen -1 -ol (9.0%),...

Forest ant composition, relative abundances, and foraging following aerial spraying of carbaryl to suppress Western Spruce budworm

Creator:: Murphy, Christopher F.
Abstract:: An outbreak of western spruce budworm Choristoneura occidentalis in the Blue Mountains of eastern Oregon in 1983 was treated with helicopter applied carbaryl. Effects of the spraying on forest ants were determined from pre- and postspray samples taken from two carbaryl sprayed and two unsprayed plots. In each 0.75-ha plot,...

Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

Fish oral antigen delivery system development and optimization

Creator:: Zhang, Jia Ai (Allen)
Abstract:: Oral administration is the most practical way of vaccination of fish. It has advantages over intraperitoneal injection and immersion methods that include no stressful handling, no interference with routine fish husbandry and antigens can be delivered to the fish in their feed. An oral antigen delivery system was developed for...

Watershed response to western juniper control

Creator:: Deboodt, Timothy L.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

Population ecology of the dusky Canada goose (Branata candensis occidentalis Baird)

Creator:: Sheaffer, Susan E.
Abstract:: Adult dusky Canada geese (Branta canadensis occidentalis Baird) were banded with plastic neck bands and observed on the winter range during 1985-92. Annual survival rates of adult geese estimated from observation data ranged from 76% to 85%. A model of Canada goose population dynamics was developed to illustrate relationships between...

Possible association of grain protein content, harvest index and biological yield in winter wheat populations

Creator:: Costa, Jose Maria
Abstract:: A negative relation between grain protein content and grain yield is frequently observed in wheat (Triticum aestivum L. em Thell) i.e. as grain yield increases, grain protein decreases. It has been suggested that the inverse relation between grain yield and protein is in part the result of developing high yielding...

Determination of α-Amylase activity and soluble starch content in normal and cork spotted D̀'Anjou' pear fruit

Creator:: Li, Shiao Jing
Abstract:: There was a linear relationship of [alpha]-amylase activity from 2 to 12 hours incubation in both freeze-dried and fresh 'd'Anjou' pear fruit tissue. Activity was greater, however, in fresh as compared with freeze-dried tissues. [alpha]-Amylase activity from both types of samples was not detected until 60 minutes incubation. After 90...

Pre-harvest sprouting tolerance of a synthetic hexaploid wheat (Triticum turgidum L. x Aegilops tauschii Coss.)

Creator:: Rosa, Andre Cunha
Abstract:: Pre-harvest sprouting in wheat costs farmers millions of dollars every year. Pre-harvest sprouting tolerance (PST) has minimized this problem, but improvement of PST is still necessary. Synthetic hexaploid wheats (synthetics) have been used as sources of genes coding for many useful traits. Two studies evaluated the PST of a synthetic...
