Stand Risk Rating For The Southern Pine Beetle: Integrating Pest Management With Forest Management, Gordon L. Autry Apr 1982

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 Feb 1982

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, …


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 Feb 1982

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 …

Selection Of Biotype Populations 2 And 3 Of Nilaparvata Lugens By Exposure To Resistant Rice Varieties, P. K. Pathak, E. A. Heinrichs Feb 1982

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 Feb 1982

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 …

Effect Of Herbicides On Performance Of Aerobic Dairy Lagoons, John D. Bottom, Joseph L. Taraba Jan 1982

Effect Of Herbicides On Performance Of Aerobic Dairy Lagoons, John D. Bottom, Joseph L. Taraba

Biosystems and Agricultural Engineering Faculty Publications

The herbicides glyphosate, bromacil, and dalapon were assessed for their affect on the oxygen uptake of microorganisms from an aerated dairy lagoon at 20 °C. The maximum recommended addition of herbicide active ingerdient to a lagoon is: glyphosate (isopropyl amino salt)—0.42 mg/L; bromacil—3.70 mg/L; and dalapon (85.8 percent Na salt and 14.2 percent Mg salt)—1.95 mg/L. In addition, microorganism isolates from the aerobic dairy lagoon were incubated under aerobic and anerobic conditions at room temperature to assess the effects of the herbicides. Under aerobic incubation, it was found that neither herbicide type nor herbicide concentration affected isolate growth. Under anaerobic …

Irrigation Development: It's Potential Impact On South Dakota's Economy, Richard Shane, Ralph J. Brown Jan 1982

Irrigation Development: It's Potential Impact On South Dakota's Economy, Richard Shane, Ralph J. Brown

Economics Research Reports

Irrigation development has been and will continue to be a key issue facing the people of the state of South Dakota. As irrigated acreage increases, benefits accrue throughout the State. The irrigator's income earning potential is expanded and income variability is reduced as drought impacts on yields are ameliorated. In addition, a more stable, larger quantity of feed can be produced for livestock production. This may allm-1 for expansion in the livestock industry or less importation of feedstuffs into an area. The nonfarm economy may also benefit from irrigation development. Since irrigation requires the purchase of more inputs such as …

1982 Annual Report Jan 1982

1982 Annual Report

Southeast Research and Extension Center: Reports and Administration

1982 was a year of challenges for all the various members of our unit including the researcher, the extension worker, the forester, and all the support staff. Our program year started on October 1, 1981 and ended on September 30, 1982.

From the agriculture standpoint, it has been a difficult year. The fall of 1981 was not favorable to the agricultural producer. Rain, freezing temperatures and even light snow was prevalent in October, 1981. Throughout the winter of 91-82, it was cold and snow was on the ground most of the winter.

It was not uncommon for counties in the …
