PERFORMANCE REPORT State: Louisiana Project Number: W-55-25 Project Title: Upland Survey Period Covered: July 1, 2010
PERFORMANCE REPORT State: Louisiana Project Number: W-55-25 Project Title: Upland Survey Period Covered: July 1, 2010 - June 30, 2011 Study Number and Title: V-4, Bobwhite Fall Whistling Surveys Study Objective: To determine relative size and distribution of bobwhite populations in Louisiana. Study Abstract Bobwhite fall whistling counts were conducted statewide along 32 routes (7 additional routes were assumed zeros and 4 others were unable to be run). Fall whistling counts did not differ (P = 0.3482) among the 5 habitat types for 2010. They did, however, differ between 2009 and 2010, with more whistling counts detected in 2009 than in 2010 for both the Northwest mixed shortleaf and loblolly pine-hardwood and Florida Parishes loblolly pine habitats. No coveys were recorded on the Northwest mixed shortleaf and loblolly pine- hardwood or Mississippi/Atchafalaya agricultural belt (0.00 whistles/stop) in 2010 (Tables 1 and 2). Jackson- Bienville WMA, Camp Beauregard, and Vernon District No. 1 routes yielded 0.25, 0.00, and 0.10 whistles/stop, respectively (Table 3). Five (5) summer bobwhite counts were conducted on the Sandy Hollow Wildlife Management Area. Counts ranged from 12-45 (Figure 1). The 2011 mean count was 27.6, which is the same as in 2010. The peak count (45) was lower than the long-term (1986-2010) average peak count of 89.3, but was higher than 8 of the past 10 years (Figure 2). A. Activity: Fall whistling counts were conducted along 37 pre-selected routes to determine relative size and distribution of fall bobwhite populations. The 5 habitat types surveyed were historic longleaf pine, mixed shortleaf and loblolly pine-hardwood, loblolly pine (Florida Parishes), the rice belt and the Mississippi/Atchafalaya agricultural belt. -

Warehouses United States Department of Agriculture Licensed Under the Farm Service U.S. Warehouse Act Agency Deputy Administrator for Commodity As of December 31, 2014 Operations LICENSED AND BONDED WAREHOUSE The Storage of Agricultural Products Is Locked Into the Marketing System Through -- Farmers Who Produce Warehouse Operators Who Store Bankers Who Loan Merchants Who Buy and Sell Processors Who Manufacture Consumers Who Use Users of Electronic Warehouse Receipts and other Electronic Documents With Assurance of Return of the Stored Commodity in Marketable Condition. And the Key Is Integrity of the Warehouse Operator and the Warehouse Receipt Through -- Financial Responsibility Warehouse Facilities and Practices Management’s Ethics and Capabilities Licensing Bonding Examination Electronic Providers March 2015 BACKGROUND INFORMATION LEGISLATIVE The United States Warehouse Act (USWA) or the Act was originally passed by AUTHORITY the Congress on August 11, 1916. On November 9, 2000, the President signed the Grain Standards and Warehouse Improvement Act of 2000 (Public Law 106-472) which amended the USWA in its entirety and modernized the regulation of Federal warehouses to better reflect current trade and operational practices. The 2000 Act authorizes the Secretary of Agriculture to license and examine public warehouse operators that store agricultural products. It also gives the Secretary broad authority to improve the administration of various aspects involving the trade of agricultural products under the purview of the USWA, including the use, establishment and maintenance of electronic warehouse receipts and other electronic documents for all agricultural products. The USWA is considered a “permissive regulatory act.” It is permissive because it only applies to warehouse operators who voluntarily apply for licensing and regulatory because each licensee must operate under its provisions and be subject to the regulations and licensing agreements administered by the USWA. -

This paper is dedicated to the memory of the late Chiung-Cheng Ko. Simple Summary: Phytoseiulus persimilis Athias-Henriot, a mite species widely used in pest manage- ment for the control of spider mites, has been commercialized and introduced to numerous countries. In the 1990s, P. persimilis was imported to Taiwan, and a million individuals were released into the field. However, none have been observed since then. In this study, we explored the ecological niche of this species to determine reasons underlying its establishment failure. The results indicate that P. persimilis was released in areas poorly suited to their survival. To the best of our knowledge, the present study is the first to predict the potential distribution of phytoseiids as exotic natural enemies. This process should precede the commercialization of exotic natural enemies and their introduction Citation: Liao, J.-R.; Ho, C.-C.; Chiu, into any country. M.-C.; Ko, C.-C.

Texas Rice June 2010 Volume X Number 4
Texas Beaumont, Texas Rice June 2010 Volume X Number 4 Past, Present, and Future Disease Management in Rice The Texas Rice Belt provides a warm, humid climate favorable for the development of many rice diseases. Rice diseases cause significant reductions in yield, grain quality, and income to rice growers. The development of diseases is greatly affected by many factors including varietal resistance, environmental conditions, and agronomic practices. As a result, the prevalence and severity of diseases significantly vary with year and location. However, losses from certain diseases can be reduced by the use of resistant varieties, improved practices and management, and effective fungicides and their combinations. The purpose Fig. 1. Severity of brown leaf spot in rice varieties affected by year of this article is to briefly review past of varietal release. and current rice diseases and their management and to outline future by Bipolaris oryzae in 1934, leaf smut caused by disease management of rice in Texas. Entyloma oryzae in 1934, narrow brown leaf spot Rice diseases have changed profoundly in caused by Cercospora janseana in 1935, and kernel severity and importance affecting grain yield over smut caused by Tilletia barclayana in 1936 (Atkins, the past 100 years of Texas rice production. Since the 1975). These diseases were commonly seen in rice first Texas rice production in the 1800’s, rice diseases fields. However, leaf smut, narrow brown leaf spot, have continued to be one of the factors limiting rice and kernel smut were minor in damage to rice. Brown production. It was believed that some of the earliest leaf spot could cause severe damage to rice under rice diseases were originally introduced along with favorable environmental conditions. -
Chapter 7 SPACE, TIME, and VARIATION S
Chapter 7 SPACE, TIME, AND VARIATION s G gi l~ oj . some species can Indeed be said to dl C( have had a single and sudden origin, local o Ized and capable of being located. With is others, however, the or/gin Is no origin at 01/ d, but a gradual transformation extending over wide areas and long periods and shifting Its focus In the course of time. Between the two Is every gradation. D.C. Darlington and EK Janakl Amma!, 1945 1 n s' b c s s e ( '\;, Space, Time, and Variation! KINDS OF PATTERNS OF VARIAnON Geographic patterns of variation have historically been used to trace the ori gin and evolution of cultivated plants. We have seen that Vavilov (1926. 1949/50) thought that areas of maximum genetic diversity represented centers of origin and that the origin of a crop could be identified by the simple proce dure of analyzing variation patterns and plotting regions where diversity was concentrated. It turned out that centers of diversity are not the same as centers of origin. yet many crops do exhibit centers of diversity. The phenomenon is real and requires explanation. What causes variation to accumulate in secon dary centers is not too well understood, but some observable factors are: 1. A long history of continuous cultivation. 2. Ecological diversity. many habitats accommodate many races. 3. Human diversity, different tribes are attracted to different races of the crop. 4. Introgression with wild and weedy relatives or between different races of a crop. There may be other causes. but the reasons for secondary centers are hu man. -

Oryza Vol. 46. No.4, 2009 (318-322) Biology of rice sheath mite, Steneotarsonemus spinki Smiley K. A. Patel* and M. S. Purohit Department of Agricultural Entomology, N.M. College of Agriculture, Navsari Agricultural University, Navsari – 396450, Gujarat, India ABSTRACT Biology of the rice tarsonemid mite Steneotarsonemus spinki was studied under laboratory at 28 ± 2.1°C temperature and 88 ± 5.9 per cent relative humidity during September 2003.Both the sexes passed through three stages viz. egg, larva, and adult and a short resting period known as quiescent stage. The egg stage lasted on an average 3.32 ± 0.55 days. Average larval period for male was 1.23 ± 0.44 and for female 1.52 ± 0.52 days and quiescent period was 0.53 ± 0.22 day for male and 0.66 0.24 day for female. Adult period was 5.28 0.54 days for male and 6.68±0.98 days for female. The total life cycle was completed in 12.20 ± 1.47 days and 13.75 ± 1.17 days for male and female, respectively. The pre-oviposition, oviposition and post-oviposition periods were 1.40 ± 0.39, 4.50 ± 1.20 and 1.65 ± 0.47 days, respectively. The female laid average 20 ± 5.03 eggs during its life span. The sex ratio (female:male) was recorded 1:1.5 and 1:2.8 in laboratory and field conditions, respectively. Key words: rice, sheath mite, Steneotarsonemus spinki, biology South Gujarat is an important rice growing tract of the Tarsonemid mites directly or indirectly causes state covering 2.3 lakh hectares area under cultivation considerable amount of quantitative and qualitative which accounts for 34.63 per cent of the total rice losses in rice production.
