Book Review: Bugs In The System By: May R. Berenbaum, Pierre Jolivet

Insecta Mundi

In one of her latest papers in the American Entomologist, in 1995, Prof. Berenbaum mentions how young people (and entomologists alike) are martyrizing insects and arachnids, by pulling their wings or their legs, burning them with magnifying glasses, without mentioning the lepidopterists who transfix the thorax of the female butterflies to induce them to lay eggs. Such behavior was once one of the acts of the emperor Nero when he was a child. His tutor, the philosopher Seneca, when he saw him pulling the wings off a fly, predicted that he would be very cruel. It was said t h …

Analyzing Correlations Of Three Types In Selected Lines Of Drosophila Melanogaster That Have Evolved Stable Extreme Geotactic Performance, Scott F. Stoltenberg, Jerry Hirsch, Stewart H. Berlocher

Department of Psychology: Faculty Publications

The behavior-genetic analysis of Drosophila melanogaster with geotactic performance as the phenotype is an ideal model system with which to investigate the complex relations between heredity and behavior. As part of a long-term, 38-year study, we report 4 experiments that identify and analyze trait correlations in the selected high- and low-geotaxis lines. We performed F₂ correlational analyses and backcrosses to examine 3 types of correlations: (a) genotype-genotype (alcohol dehydrogenase [Adh]-amylase [Amy]), (b) genotype-phenotype (Adh and Amy-geotaxis), and (c) phenotype-phenotype (mate preference–geotaxis). Only the Adh-geotaxis correlation survived meiosis and reappeared in the F …

Cucumber Mosiac Virus In Lupins, Annette Bwye, Roger Jones, Wayne Proudlove

Journal of the Department of Agriculture, Western Australia, Series 4

Cucumber mosaic virus is a threat to lupin crops from Geraldton to Esperance, particularly to those growing in areas receiving more than 400 mm average annual rainfall. The disease markedly decreases grain yield in narrow-leafed and yellow lupins but doesnot infect albus or sandplain lupins. Worldwide , after bean yellow mosaic virus, cucumber mosaic virus is the second most important virus affecting lupins. Annette Bwye, Roger Jones and Wayne Proudlove outline the symptoms, spread and management of this serious disease.

Effects Of Selection For Halothane Resistance On Lipid Concentration And Composition In Drosophilia Melanogaster, Paula S. Fritsch, Dave Dapkus

Journal of the Minnesota Academy of Science

Drosophila melanogaster is increasingly used as a model system for anesthesia studies. Lipids may play a role in anesthetic resistance by sequestering the hydrophobic anesthetics from nervous tissue. Alternatively, changes in membrane lipid composition (phospholipids and/or cholesterols) may contribute to resistance through alteration of neurological membranes. This project studied the relationship of lipids to anesthetic resistance in a strain of Drosophilia melanogasier with a high level of halothane resistance produced by 13 generations of mass selection. The estimated dose of anesthetic needed to produce anesthesia in one-half of the flies tested (ED50( for this strain was 2.3 times that of …

The Effects Of Density And Ddt On An Inversion Polymorphism In Drosophila Melanogaster, Paul H. Zuzick, Dave Dapkus

Journal of the Minnesota Academy of Science

Inversion polymorphism may be maintained by some form of balancing selection, A laboratory population maintained for many years at small size should contain little genetic variation due to the effects of genetic drift. This study analyzed a Drosophila population which exhibits a persistent inversion polymorphism. The population has been subjected to selection for DDT resistance since 1959. The purpose of this study was to determine if: a) balancing selection was involved and b) if the selection was DDT-related. To study these questions, three pairs of populations were set up at different inversion frequencies: 95%, 55% (equilibrium value) and 5%. One …

Introduction Of An Integrated Pest Management Program To A Greenhouse: Establishing And Monitoring Predatory And Parasitic Insects For Biological Control, Siobhan E. O'Reilly, Christopher T. Cole

Journal of the Minnesota Academy of Science

An experimental Integrated Pest Management (IPM) program was developed to reduce the use of pesticides m me greenhouses at the University of Minnesota, Morris. Six predatory or parasitic insect species were released to control populations of aphid, scale, mealybug, thrips, whitefly, and spider mite. Beneficial insect populations were supplemented several times. Pest and beneficial insect populations were monitored weekly for one' year. No pest species were eliminated but all except scale were effectively controlled. Aphid and whitefly control was effective within the first two months; control of the other pest insects took from 5 to 6 months to a year. …

Rice Pests Of Shifting Cultivation In Côte D'Ivoire, West Africa, E. A. Heinrichs, D. E. Johnson, J. K. Afun, D. J. Robison

Department of Entomology: Faculty Publications

Traditional shifting cultivatiOn appears to be sustainable if fallow periods are sufficient to restore soil fertility, maintain soil structure and suppress pests. These traditional systems are threatened in West Africa because of increasing land pressure resulting in shorter fallow periods. Studies were conducted on farmers' fields in Côte d’lvoire to determine how fallow length affects populations of insect pests and their natural enemies and weed growth and yield losses due to weeds. Length of fallow influenced the abundance of certain arthropod species as indicated by sweep-net sampling. Populations of the stalk-eyed flies Diopsis spp., leaf·feeding beetles, and leafhoppers/spittlebugs were significantly …

Foraging Preferences Of The Introduced Honeybee In Winter Flowering Banksia Woodland : Implications For The Management Of Flora And Fauna Of Conservation Areas, Simon Lawrence Judd

Theses : Honours

The Honeybee (Apis mellifcra) is arguably Australia's most abundant feral animal, and relatively little is known about its interactions with the Australian biota. A lack of such information makes it difficult for the managers of nature conservation areas to decide whether beekeeping is appropriate and whether attempts should be made to control feral bees. This study made observations of feral honeybees and native pollinating invertebrates for one hundred and twelve hours, at fifteen sites in Banksia woodland, between July 27 and September 10, 1995. Flowering and preflowering invertebrate assemblages of Leucopogon polymorphus, an epacrid shrub which provided …
