12 KU Students to Studv Cockroach Control
This summer 12 students at KU will study methods that may be used to control cockroaches without using pesticides. A $14,920 grant given last week by the National Science Foundation will finance the research of biological control of cockroaches.
Although it isn't yet known whether biological controls will work for controlling pests in a school setting, Richardson, Texas, graduate student and project director, said. Other methods of control are desirable because of the effects of pesticides on the environment and on plants.
Neither cockroaches that have been in a sewer or other filly place nor pesticides are welcome additions to a kitchen, hospital or factory, according to another project member, Mike Breed, Overland Park graduate student.
BREED AND SAMS SAID the best way to get rid of cockroaches was to keep one's house dry and clean. Because keeping a house dry and clean isn't as easy or as safe as they might seem, cockroaches are serious pest almost everywhere man congregates.
"Cockroaches are the oldest insect group that still exists," Breed said. Cockroaches are nocturnal, like damp places, usually have an unpleasant odor and will eat a variety of things, including leather, paper, food, or pet products. Viruses on their bodies and may be a source of stress to people who have to live or work in cockroach-infested areas.
Of the more than 1,200 species of cockroaches in the world, four are common in the Lawrence area, according to Breeders of North America. They are most common and the smallest, averaging about a half-inch in length. The three other varieties are Ameri-an; Oriental and brown-banded American cockroaches, the two largest; and the Lawrence area, may be an inch-and-a-half long.
THE PURPOSE OF THE KU PROJECT is to coordinate ideas about different aspects of biological control of cockroaches. The multi-disciplinary project will cover physiological, behavioral and ecological aspects of biological control.
The physiological effect will focus on the effects and mechanisms of a cockroach
hormone on different age groups. It is suspected, Sams said, that the hormone may accelerate reproduction in mature females and leading development in immature cockroaches.
Pheromones, chemical substances that stimulate individuals of the same species, are the focus of the behavioral aspect of the project. Agricultural entomologists have begun to use pheromones in insect control programs, according to Sarma and Breed.
A sex pheromone called "Gyp Lure" is used on the East coast to disrupt the mating and stop the aggy moth from causing damage. The effect of the pheromone also been controlled by using a pheromone.
IN ADDITION to studying the possibility of using a sex pheromone to disrupt cockroach mating, an aggregation pheromone will be studied as a possible bait in traps. The sex pheromone comes from female cockroaches in their attempts to mate. The aggregation pheromone is more general, causing groups of cockroaches to gather.
The students in the project must isolate
these pheromones and replicate them in order to study their effects.
Whether either of these pheromone techniques will work depends on the percentage of each sex and different age groups in naturally occurring cockroach populations. That is why ecological aspects of cockroaches will be studied to determine whether biological controls will work outside a laboratory.
Age and sex structure and the size of cockroach populations will be determined by what is called the capture-recapture method. This means that cockroaches will be marked and released after they are first caught in traps set in cockroach-infested dwellings and commercial buildings. The population of cockroaches can be used to determine the constitutivity of an entire population of cockroaches.
WILLIAM BELL, associate professor of entomology and physiology and cell biology, is the faculty advisor for the project. The project was begun by students.
In addition to Breed and Sams, five students already involved in the project
New Class to Cut Fear of Science
Physics Course Tries to Encourage Natural Curiosity
If you are a "science-shy" student but need science to fulfill a requirement, the physics department has solved your dilemma.
The department of physics and astronomy will introduce Physics 103 next fall, a course designed mainly for elementary education majors who need a physical lab science to meet the School of Education requirements.
The course is based on a nationally adopted program employing the discovery method. This program was developed over a 10-year period, at a cost of $643,369 by the Science Foundation, and it is aimed at prospective elementary school teachers.
According to Robert C. Bearse, associate professor of physics and astronomy, the course will take the scare out of science and teach that will encourage natural curiosity.
Bearse said he hoped the course would give students confidence in dealing with real-world problems.
"We hope to teach the student to ask questions about the world around us and design ways of answering these questions, instead of just memorizing facts," he said. "But we won't get answers from the professor for every single question, if we teach it right."
Bearse and Davis will teach the course next semester.
The course itself will employ the discovery method. Students will conduct many short experiments in and out of class and follow them with discussions directed at exposing the underlying physical principles.
and one 1-hour demonstration lecture. The discussion lab class is limited to 30 students and will be led by a full-time faculty member.
The class will meet five hours a week- 2-hour discussion-laboratory sessions
The University of Kansas version cf the national course was developed by Beurse; Robin E. P. Davis, associate professor of physics and astronomy; Francis W. E. Smith, associate professor of physics and astronomy and William La Shere, associate professor of education.
There will be no lab fee for the students,
nor will there be a final exam.
*We intend to keep the course away from them.*
to change the attitudes toward science. Students have always feared science and we hope to lessen much of the preconceived notions they have toward the sciences. "Bearse said,
"The faculty is excited over the prospects because the course is a real attempt for us
Campus Annexes to Be Removed
Temporary annexes have been a necessary part of life at the University of Kansas, but some of them will be removed within the year, according to Allen Wiechert, assistant director of Facilities, Planning and Operations.
Wesco Hall has been completed, and removal of the Wakkins Hospital Armex, was carried out.
amneses A and B is scheduled within the next 12 months, he said recently.
These annexes probably will be moved to west campus or to one of the University's research locations, such as the Natural History Museum, of Lawrence Municipal Airport, he said.
After the completion of the Visual Arts Center and the Law Center in 1977, Marvin
annexes N and D and Green Annex will be relocated. Oread Hall, Lindley Hall Annex and Bailey Hall Annex probably will be destroyed, he said. By 1977 these "temporary" structures will have been on the campus for more than 30 years.
Means of Rape Prevention Discussed by Task Force
There have been 31 incidents of rape, attempted rape, assault, battery or molestation since November 1972, according to a report compiled by the Kansas Department Center. Nine of these incidents have occurred at night and 22 during daylight hours.
These figures were listed in a report written by Kathy Hoggard, director of the Information Center, and Moll Laffyn, director of Lewis Hall, Barbara O'Brien, and Mary Brennan, respectively. The figures at the second meeting of the Rape Prevention Task Force Sunday.
Construction of the Visual Arts Center is the top priority, Wiechherd said. Classrooms, studios and offices for the visual arts scattered on and off campus in 13 locations.
The members of the Task Force who attended yesterday's meeting discussed information they obtained concerning programs suggested at the first meeting. At that meeting, members suggested that they should be better determined by increased lighting. Other ideas included establishing phones on campus that would be connected directly with
campus security offres and establishing a student foot patrol unit to walk the campus area after 4 p.m. in an attempt to help students and to help if an assault would occur.
O'Brien said that because the majority of assault-related incidents occurred during the day, lighting would be a less feasible option than establishing campus security phones.
Robert Nash, Lawrence junior, said that Traffic and Security seemed to support the idea of the student patrol unit, but because of a lack of funding the patrol would have to be established on a voluntary basis. There is no information which could be given to volunteers. Nash said.
The Task Force will meet at 2 p.m. Sunday in Lewis Hall to plan, discuss and prepare a meeting with you.
Visual Arts will remain in Oread Hall and Bailey Hall annexes until the new center is completed. Lindley Hall Annex will house weaving and silver smithing classes until a mechanical Engineering building is raised on the Visual Arts Center is built in its place.
An expansion of the parking lot southwest of Lindley Hall is planned to replace Lindley Annex. A tunnel running under Nesmith Drive will connect the parking lot to the Learned Hall addition now under construction, Weichert said.
After the hall all it is completed, work on the tunnel will begin. Construction will be scheduled for one summer, possibly 1975 or 1980. Construction Drive will be torn up during construction.
"We want to get the tunnel completed before classes begin in the fall. We want to avoid what happened to us on the Union tunnel," he said.
The Union tunnel was built in the summer of 1968, he said. It was to be finished in time for the first football game, but heavy rains that summer postponed completion.
