Tolerance Of The Rice Variety Triveni To The Brown Planthopper, Nilaparvata Lugens, D. T. Ho, E. A. Heinrichs, F. Medrano

Department of Entomology: Faculty Publications

Seedling screening and survival and population growth studies on 30-day-old plants indicated similar degrees of susceptibility on Taichung Native 1 (TN1) and Triveni rice to Nilaparvata lugens (Homoptera: Dilphacidae). However, studies in the screenhouse and field indicated that at both the vegetative and mature stage, Triveni possesses tolerance to insect damage, expressed as the ability to survive and produce a higher percentage of productive tillers than TN1 at similar N. lugens populations. Yield reduction caused by feeding of N. lugens was ca. 40% when infested with 400 N. lugens on 35-, 50-, or 75-day-old plants, whereas it was almost 100% …

Crop Budgets For Irrigated Agriculture In Central-East Central South Dakota - 1982, Richard Shane

Economics Research Reports

Irrigation development in all of South Dakota has received much attention in the past years. Today several major water development projects are being considered. These projects include both surface and groundwater resources. That some development, whether public or private, will take place seems to be a foregone conclusion. In order for individual crop producers to decide whether to adopt irrigation technology or not requires an evaluation of profit potential with and without irrigation on their land resource. Most potential irrigators have personal records from which to derive dryland enterprise budgets to use in profit projections. Dryland producers with no irrigation …

An Approach To Selection Of Variety And Planting Date In Corn Silage Production, Carlos A. Luna-Gonzalez

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The major purpose of this study is to make additional information available to the farm manager to improve the decision-making process relating to corn silage production. This study is primarily concerned with factors that influence planting date and variety selection. With-in the framework of decision theory analysis, a Bayesian approach is employed to calculate the best time to plant and the best variety to plant. The approach is used both with and without the possible occurrence of harmful spring frosts. The "seventy growing degree day" method is employed as a criterion for planting date selection. The planting dates are matched …

Stand Risk Rating For The Southern Pine Beetle: Integrating Pest Management With Forest Management, Gordon L. Autry

Faculty Publications

Stand risk rating for the southern pine beetle.

Dendroctonus frontalis Zimm., is a first step toward dealing with a serious but sporadic insect problem. Two approaches, one utilizing readily available resource data, the other employing data obtained from aerial photographs, illustrate application of current knowledge to meet the protection needs of resource management-the primary role of integrated pest management. During a 36-month period in Louisiana, high-risk stands accounted for 13.4 infestations per 1,000 acres, four times the rate of low-risk stands; in Texas high-risk stands accounted for 9 .9 infestations per 1 ,000 acres during 1973-1978, almost five times the …

Effects Of Insecticides On Nilaparvata Lugens And Its Predators: Spiders, Microvelia Atrolineata, And Cyrtorhinus Lividipennis, W. H. Reissig, E. A. Heinrichs, S. L. Valencia

Department of Entomology: Faculty Publications

Thirty-five insecticides used on rice in Asia were tested in the field against Nilaparvata lugens. The most important predators of the pest, Cyrtorhinus lividipennis, Microvelia atrolineata, and predacious spiders, Lycosa pseudoannulata, Tetragnatha, and Araneus species, were also monitored in the test plots. Ten insecticides significantly reduced numbers of N. lugens, but propoxur and ethylan gave the most consistent and effective control. Most insecticides did not significantly reduce populations of spiders and M. atrolineata compared with untreated checks, but they did reduce numbers of C. lividipennis. Fifteen treatments caused resurgence of N. lugens, …

Selection Of Biotype Populations 2 And 3 Of Nilaparvata Lugens By Exposure To Resistant Rice Varieties, P. K. Pathak, E. A. Heinrichs

Department of Entomology: Faculty Publications

The release of an insect pest-resistant variety and subsequent adaptation of the insect species to that variety through the process of biotype selection has occurred on many cultivated crops. The present study was designed to obtain detailed information on some of the processes involved in the selection of biotypes of Nilaparvata lugens (Stål) on two rice varieties with different major genes for resistance. The N. lugens population selected for the study, which had originally been collected in the field and reared on a susceptible variety for 12 years (ca. 140 generations), initially had a low survival on the resistant rice …

Insecticide-Induced Resurgence Of The Brown Planthopper, Nilaparvata Lugens, On Rice Varieties With Different Levels Of Resistance, W. H. Reissig, E. A. Heinrichs, S. L. Valencia

Department of Entomology: Faculty Publications

Three rice varieties, IR29, IR40, and IR42, which are, respectively, susceptible, moderately resistant, and resistant to Nilaparvata lugens Stål in the Philippines, were treated in the field with decamethrin, an insecticide known to cause resurgence. N. lugens populations increased to a significantly higher level in the treated plots than in untreated checks, but the degree of resurgence varied among varieties. The maximum population increases in the treated plots compared with the checks were ca. 74-, 50-, and 5-fold, respectively, for IR29, IR40, and IR42. Decamethrin was toxic to predators, and this reduction of natural enemies of N. lugens may …

Resurgence Of Nilaparvata Lugens (Stål) Populations As Influenced By Method And Timing Of Insecticide Applications In Lowland Rice, E. A. Heinrichs, G. B. Aquino, S. Chelliah, S. L. Valencia, W. H. Reissig

Department of Entomology: Faculty Publications

Resurgence of Nilaparvata lugens (Stål) after insecticide application is a common phenomenon in rice in South and Southeast Asia. Among other insecticides inducing resurgence, carbofuran, decamethrin, and methyl parathion were selected for this study. Of the various methods of carbofuran application tested, foliar sprays were most active in inducing resurgence. Extent of resurgence was highly influenced by time of insecticide application. Sprays of methyl parathion and decamethrin applied 50 and 65 days after transplanting (DT) induced resurgence in the third generation of N. lugens at ca. 90 DT, whereas earlier applications had little effect. The cause(s) for resurgence was not …

Cooperative variety trials were conducted at 33 locations to determine field, storage, and processing behavior of selected potato clones and varieties when grown under soil, climatic, and cultural conditions common to the potato growing areas of 12 cooperating States and the Province of New Brunswick, Canada. These trials are all contributions to Regional Project NE107 entitled, "Breeding and Evaluation of New Potato Clones in the Northeast Area."
