The History of Bed Bug Management -- With Lessons from the Past

For a limited time, "The History of Bed Bug Management -- With Lessons from the Past" by Dr. Michael F. Potter, University of Kentucky, will be available to the public for free at http://entsoc.org/history-bed-bug-management.

The article, which appears in the Spring 2011 edition of American Entomologist, provides a historical review of the impacts of bed bugs and their management.

"Bed bugs have been biting us since the beginning of recorded time," Potter writes. "Perhaps the most unsettling aspect of 21st century bed bugs is that we are in uncharted territory ... The foundation of bed bug management still consists of hard work, public education, and constant vigilance to prevent or detect infestations in the early stages."

In the article, Dr. Potter explains that throughout history mankind has suffered from bed bug bites. It was only during the second half of the 20th century that humanity received a reprieve from the sleep-depriving parasites, thanks mostly to the availability of potent residual pesticides.

Some interesting bed bug facts that appear in the article are:

- Experts believe the bugs initially fed on bats and then began feeding on humans. Bed bugs have been around since the caveman days.

- Bed bugs were first reported in England in 1583, and they hitchhiked their way to the Americas aboard ships.

- Exterminators were battling bed bugs at least as far back as 1690.

- Bed bugs received a big reproductive boost in the early 1900s, when central heating of buildings became common. Bed bug populations had previously followed a more seasonal trend, but heated buildings allowed them to thrive year-round.

- In Europe in the 1930s and ‘40s, an estimated one-third of dwellings in major cities had bed bugs.

- In the 1930s, a survey of 3,000 moving vans in Stockholm, Sweden found bed bugs on 47% of the vans inspected, foretelling big concerns for moving and storage companies today.

- In 1895, a Chicago jury ruled that “no man shall be required to pay rent for a house infested with bedbugs.” Editorializing on the verdict, the news media noted that if the ruling held, “the great majority of Chicagoans would be relieved of their rent bills.”

CSI y los insectos exóticos en Puerto Rico

"CSI Puerto Rico: Aventuras en Entomología Forense" y "Especies exóticas invasoras en la cuenca del Caribe: Preocupación para los Estados Unidos" son sólo dos de los simposios que se presentarán la semana entrante en la Isla durante una reunión conjunta que celebrarán las Sociedades Americanas de Entomología y Fitopatología.

La reunión tendrá lugar en el Hotel Caribe Hilton, en San Juan, del 19 al 22 de marzo, a donde llegarán cientos de entomólogos y fitopatólogos para discutir los problemas agrícolas y ambientales causados por insectos y enfermedades de plantas.

Según informó la Sociedad Americana de Entomología en un comunicado de prensa, el aumento en los viajes internacionales y el comercio han permitido a los insectos exóticos de diferentes partes del mundo establecerse en lugares donde no existían previamente. Esta situación, agregó la organización, cada año le cuesta millones de dólares a los agricultores, pues lo insectos destruyen sus cultivos y propagan enfermedades.

Las Sociedades Americanas de Entomología y Fitopatología le harán frente a estos y otros asuntos durante la reunión, cuyo lema este año es "Especies exóticas: Una experiencia compartida".

Otras presentaciones durante la reunión de cuatro días abordarán temas como la resistencia a insecticidas, hormigas, termitas, chinches, moscas, abejas, garrapatas, ácaros, cultivos resistentes a las plagas, uso de insectos para controlar malezas (control biológico) y enfermedades que afectan los plátanos y cítricos.

Bt Corn Symposia at Minneapolis Entomology Meeting

The following eight symposia on Bt maize will be presented at the 66th Meeting of the Entomological Society of America's North Central Branch at the Radisson University Hotel, in Minneapolis on March 13-16, 2011:

1) Bt Adoption by Illinois Producers and Refuge Management: Cause for Concern?
Time: 8:55 am Wed  Location: University Ballroom B
Michael E. Gray, University of Illinois

This presentation will focus on survey data collected from Illinois producers regarding their use of Bt hybrids to achieve insect protection. Data have been collected for several years at the University of Illinois Extension sponsored Corn and Soybean Classics. Responses from producers to a variety of questions were obtained using hand-held clickers in which anonymous feedback could be collected. Because of the escalating use of Bt hybrids, concern is increasing regarding the potential for resistance development. The results to a number of questions will be discussed such as the level of refuge compliance, refuge type preference, and likelihood of soil insecticide use with Bt. The use of seed blends (refuge-in-a-bag) as a refuge strategy is likely to become the foundation of resistance management programs in the future. Producer perspectives concerning seed blends, based upon survey responses, also will be discussed.

2) Why Use Corn Rootworm Insecticides Over a Corn Rootworm Traited Corn?
Time: 9:55 am Wed  Location: University Ballroom B
Caydee Savinelli and Craig Abell, Syngenta Crop Protection; and Patti L. Prasifka, Dow AgroSciences

Corn rootworm is sometimes known as the “Billion Dollar Insect Pest” and corn growers have used many tactics over the years to control this pest. The introduction of corn rootworm traited corn has been a step change in the control of corn rootworm. However, as with any insect control measure, the level of control may depend on the population dynamics of the target pest as well as secondary pests. This talk will address why and when it makes sense to use soil insecticides over corn rootworm traited corn.

3) Corn Rootworm Adult Emergence Patterns as Affected by Bt-RW Corn and Crop Rotation
Time: 1:50 pm Tue  Location: Nolte
Bruce D. Potter, University of Minnesota; Kenneth R. Ostlie and Jared M. Goos, University of Minnesota

During the 2008-2010 growing seasons, effects of Bt-RW hybrids and their isolines on quantitative and temporal aspects of corn rootworm beetle emergence were monitored in continuous corn and corn rotated with soybean in Dakota and Redwood County, MN. We found evidence that the Bt-RW trait delayed emergence for both corn rootworm species and both corn rotations. The implications of these emergence delays in terms of rootworm survival on transgenic corn, rootworm behavior, and monitoring of Bt-RW performance will be discussed.

4) Evaluating Response of Northern and Western Corn Rootworm to Transgenic Bt Corn
Time: 10:11 am Mon  Location: University Ballroom B
Ryan S. Keweshan and Aaron J. Gassmann, Iowa State University; Graham P. Head, Monsanto Company

The northern corn rootworm Diabrotica barberi and the western corn rootworm Diabrotica virgifera virgifera are major pests of corn in the United States. Bt corn that targets corn rootworm has been adopted rapidly by growers, and this places selective pressure on corn rootworm to evolve resistance. The pattern of adult emergence from Bt and refuge plants is an important factor affecting the development of resistance. The goal of our research was to measure patterns of adult emergence from Bt and non-Bt corn, and to assess fitness of adults surviving as larvae on Bt corn in the field. A total of four treatments were evaluated: 1) a single-trait event with Cry3Bb1 (YieldGard VT Triple), 2) a stacked event with Cry3Bb1 and Cry34Ab1/35Ab1 (SmartStax), 3) a near isogenic hybrid that did not contain rootworm active Bt and 4) a stacked event with a blended non-Bt refuge. For each of these treatments, we collected data on the abundance of adult male and female northern and western corn rootworm emerging over the course of the summer, and the fitness of these individuals, as indexed by width of their head capsule.

5) Gene Expression Profiles of Bt-resistant and Susceptible European Corn Borer Larvae (Ostrinia nubilalis) After Ingestion of Transgenic Cry1Ab Corn Leaves
Time: 9:35 am Mon  Location: Nolte
Jianxiu Yao, Lawrent L. Buschman, and Kun Yan Zhu, Kansas State University

Transgenic corn expressing insecticidal Cry1Ab from Bacillus thuringiensis (Bt) is very effective in controlling European corn borer (ECB), Ostrinia nubilalis. However, it is necessary to understand how ECB gut genes respond to transgenic corn because there is a threat ECB could develop resistance to Cry toxins. In this study, we developed a cDNA microarray built upon the ECB gut-specific EST database. The cDNA microarray contains 15,000 cDNA elements representing 2,755 different genes. We used this microarray to construct the gene expression profiles for early fourth-instar ECB larvae of the lab-selected resistant (R) strain and the susceptible (S) strain. Both strains were exposed to transgenic Cry1Ab corn (MON810-event) for 6-hrs. We identified 398 genes from the S strain and 264 genes from the R strain with a significantly increased or decreased expression (≥2.0 fold; p-value≤0.05) in comparing with unexposed larvae. Among those genes, 154 in the S strain and 88 in the R strain had putative molecular functions based on gene ontology analysis. 48 differentially expressed genes were common between the R and S strains. Interestingly, two aminopeptidase genes were up-regulated in the R strain, and down-regulated in the S strain. The rest of the genes had similar regulation in both strains. Especially, 17 genes in the S strain and 9 genes in the R strain had differential expression, which are potentially involved in Bt toxicity or/and Bt resistance. This study is the first large-scale monitoring of ECB larvae gut transcripts under exposed or unexposed to transgenic corn expressed Cry toxins

6) Incidence of Mycotoxins in Bt and Conventional Corn Hybrids in Relation to Insect Pest Abundance
Time: 9:59 am Mon  Location: Nolte
Rosemary Gutierrez, Billy W. Fuller, and Bradley L. McManus, South Dakota State University

Mycotoxins are fungal metabolites that can contaminate foods and feeds causing toxic effects in higher organisms that consume these products. The more common mycotoxins in corn are fumonisin, aflatoxin and deoxynivalenol (DON), and they are known to cause health issues in humans and animals (Hussein, 2001). Dry weather early in the season followed by wet weather during silking stage combined with insect damage on corn ears may increase the amount of fungal infection (Munkvold, 1999). Conventional and Bt corn plots were located in Aurora, South Dakota during 2009 year. Carbaryl was applied at 1.12 Kg[AI]/ha in half the plots to eliminate beneficial arthropods and thus trigger later-season pest resurgence contaminants. Sap beetles in the sprayed Bt plots were 50-fold greater in numbers than that observed in untreated-Bt plots. Corn rootworms were over 3-fold greater in conventional corn plots compared to that found in Bt treatments. Corn leaf aphid numbers were highest in sprayed-Bt plots compared to all treatments. Mycotoxins levels showed no significant differences between hybrids and insecticide treatments. Zearalenone was the only mycotoxin that showed significant differences comparing with fumonisin, aflotoxin anddeoxynivalenol (DON) in both hybrids. Zearalenone, aflotoxin, fumonisin nor DON levels were not significantly correlated with the percent of ears with visibly moldy insect-damaged kernels. Based on the levels of mycotoxins results conventional and Bt corn hybrids did not exceed the tolerated mycotoxin levels of human and animal consumption.

7) Interactions Among an Entomopathogenic Fungus, an Insect Predator, Mallada signatus (Neuroptera: Chrysopidae), and the Host, Helicoverpa armigera (Lepidoptera: Noctuidae), on Bt Cotton
Time: 10:11 am Mon  Location: Nolte
Md. H. Bahar, Alice Del Socorro, John N. Stanley, Peter C. Gregg, and David Backhouse, University of New England (Australia); Robert Mensah, Australian Cotton Research Institute

Greenhouse experiments were conducted to examine the interactions among Helicoverpa armigera, two of its natural enemies (green lacewing, Mallada signatus & an entomopathogenic fungus*) and transgenic Bt cotton. Fifty H. armigera neonates were placed on different locations of each whole potted cotton plant in a greenhouse. Two green lacewings were released and/or 50 ml fungal spore suspension was sprayed on each plant. After 96 hours both Bt cotton plant and green lacewing significantly reduced the survival of H. armigera larvae. The combined effect of green lacewing and Bt toxin on reducing H. armigera larvae was synergistic. The fungus did not affect the activities of either green lacewing or Bt cotton. In can be concluded that the predatory insect green lacewing and the entomopathogenic fungus are compatible with transgenic Bt cotton. * Due to commercial-in-confidence reasons, the name of the fungus can not be revealed.

8) Potential for Diabrotica Population Suppression with Area-Wide Adoption of Bt Corn
Time: 10:50 am Wed  Location: University Ballroom B
Nicholas P. Storer and Kevin L. Steffey, Dow AgroSciences; William D. Hutchison, University of Minnesota

Area-wide adoption of insect protected Bt corn and Bt cotton crops has led to significant reductions in certain target pest populations. Here we examine the potential for pyramided corn rootworm-active Bt traits to suppress populations of western corn rootworm in North America and Europe.

In addition, the meeting will feature an Insect Photo Salon, a hands-on photography workshop for entomologists, and symposia on bed bugs, biocontrol of invasive species, potato entomology, trends in corn IPM/IRM research, Diabrotica populations and control tactics, soybean aphid management, and insect biodiversity in urban environments.

Stink Bug Experts Gather in Pennsylvania to Address Growing Problem

The Eastern Branch of the Entomological Society of America (ESA) will meet in Harrisburg, PA to discuss the brown marmorated stink bug and other emerging insect pests

Suddenly they are everywhere. These foul-smelling bugs, originally from Asia, were first detected in Pennsylvania in the late 1990’s. Now they are damaging fruits and vegetables and invading homes in many parts of the United States.

State, Federal, University, and industry entomologists from the eastern U.S. and Canada will converge in Harrisburg, Pennsylvania, March 18-21, 2011, to discuss the brown marmorated stink bug plague during the 82nd Annual Meeting of the Entomological Society of America's Eastern Branch during a symposium called “The Plague of the Brown Marmorated Stink Bug.”

Dr. Tracy Leskey, symposium co-organizer and research entomologist at the USDA Appalachian Fruit Station, notes that this invasive stink bug is very unique because it has become a serious year-round pest. Throughout the growing season, it attacks a wide variety of fruits and vegetables. In the fall and winter, homeowners and businesses are invaded as the bugs seek shelter from the cold. Currently, the brown marmorated stink bug has been officially detected in 33 states and the District of Columbia. During the symposium, researchers and industry professionals will discuss the stink bug’s detection and spread in the U.S., its damage to orchards, wine grapes, vegetables and other crops, as well as strategies being developed to control it, including the use of parasitic wasps.

Stink bugs are just the beginning of the emerging pest problems that will be discussed at this meeting. Other destructive insect menaces looming on the horizon are Asian and lesser cedar longhorned beetles, the emerald ash borer, and the Japanese maple scale. Other meeting symposia include:

- "IDEP: New Pests and New Information on Possible Foes"
- "Teaching Entomology at Various Educational Levels: Perspectives, Techniques, and Challenges"
- "Pesticides and Pollinators"
- "Insects on Woody Plants"
- "Student Symposium: Tools of the Trade"

The 82nd Annual Meeting’s theme is “Survival of the Fittest, Insuring the Future of Entomology.” As the future of entomology belongs to students, graduate and undergraduate student research reports are a focal point of the meeting. University students throughout the east and Canada compete in Poster and Oral Competitions, judged by a panel of Society members. Student research covers a wide range of current topics, from pollination and mosquito control to the effect of deer and birds on insect populations. Eastern Branch President and Cornell Entomology Professor, Harvey Reissig, notes that there are a number of exciting symposia on the schedule, including “Pesticides and Pollinators” and a student-sponsored technology symposium which covers Synchrotron X-ray imaging, genomic analysis, harmonic radar, and biomechanics.

The three-day meeting will draw entomologists from northeastern and mid-Atlantic states and several Canadian provinces. The meeting will conclude on Sunday evening with a banquet and awards ceremony. The banquet speaker will be Judson Reid, Cornell University Extension Associate who will discuss, “The Old Order Amish Society in Pennsylvania.”
