Synopsis Of The Genera And Subgenera Of The Tribe Peleciini, And Revision Of The Neotropical And Oriental Species (Coleoptera: Carabidae), S. L. Straneo, G. E. Ball

Insecta Mundi

Phylogenetic analysis of structural features of adults shows that the tribe Peleciini comprises eight genera, grouped in two subtribes: the southeastern Australian Agonicina (new status), including Pseudagonica Moore, 1960 (type species P. nitida Moore, 1960) and Agonica Sloane, 1920 (type species A. simsoni Sloane, 1920); and the Inabresian Peleciina (new status, with Peleciini and Disphaericini of authors), including the Neotropical Eripus Dejean, 1829 (type species E. scydmaenoides Dejean, 1829), Pelecium Kirby, 1817 (type species P. cyanipes Kirby, 1817), and Stricteripus, new genus (type species Pelecium peruvianum Straneo, 1953), the Oriental Ardistomopsis, new genus (type species Disphaericus myrmex, Andrewes, …

Effect Of Host Plant On The Level Of Virulence Of Nilaparvata Lugens (Homoptera: Delphacidae) On Rice Cultivars, A. H. Bahagiawati, E. A. Heinrichs, F. G. Medrano

Department of Entomology: Faculty Publications

The virulence of a planthopper, Nilaparvata lugens (Stål) biotype 3, reared on rice cultivar ASD7and of N. lugens colonies collected on Mindanao Island in the southern Philippines and reared on the widely grown commercial cultivars IR36 and IR42 was compared. Based on plant damage, insect weight, population growth, and feeding activity, the Mindanao N. lugens colonies reared on IR36 and IR42 were more virulent than biotype 3, although ASD7, IR36, and IR42 have the bph2 gene for N. lugens resistance. These results clearly indicate that in the screening of breeding lines for resistance to N. lugens, it is …

Colonization Of Immature Black Flies (Diptera: Simuliidae) On Artificial Substrates In A Nebraska Sandy River, K. P. Pruess

Department of Entomology: Faculty Publications

Colonization of Simulium bivittatum Malloch and S. luggeri Nicholson and Mickel on artificial substrates exposed for two consecutive time periods of 1, 2, or 4 d was contrasted with colonization after continuous exposures of 2, 4, or 8 d. Reduced colonization of early instars of both species during the second 4-d period was attributed to an aging population, whereas reductions in total black flies after 8 d seemed to be caused by substrate changes. Numbers of pupae increased as exposure time increased.

Evidence For The Role Of Ecdysteroids In The Genital Sex Pheromone Of Two Species Of Hard Ticks, Dermacentor Variabilis (Say) And Dermacentor Andersoni Stiles, Demar Taylor

Biological Sciences Theses & Dissertations

Neutering of part-fed females virtually eliminated copulatory behavior in Dermacentor variabilis and D. andersoni males. Extracts from the anterior reproductive tracts (ART) of part-fed (7 days) females restored the male copulatory behavior in conspecific neutered females, suggesting the presence of a genital sex pheromone (GSP). Similar extracts from unfed females did not restore the behavior, suggesting that the pheromone was produced during feeding. Perception of the GSP by sensillae on the male cheliceral digits was confirmed by electrophysiological techniques.

Ecdysteroids, specifically ecdysone and 20-OH-ecdysone were shown to be present in the anterior reproductive tracts in excess of amounts that could …

A New Species Of Moranida Mansell From Venezuela (Neuroptera: Nemopteridae), Robert B. Miller, Lionel A. Stange

Insecta Mundi

Mansell (1983) described two new species and genera of Crocinae from Peru and Bolivia bringing the total number of South American species of this subfamily to five species. However, all five species occur well south of the equator. Recently the authors discovered a sixth species in northern Venezuela greatly extending the northern range of the family in South America. This new species belongs to the genus Moranida Mansell. Both adults and larvae were found and are described here with a key to the species of Crocinae of South America. We also found and reared Moranida peruviensis Mansell from Lambayeque, Peru, …

Book Review: Larvas De Coleoptera Do Brasil By Cleide Costa, Sergio A. Vanin, And Sonia A. Casari-Chan, P. Jolivet

Insecta Mundi

This is a remarkable new book which is certainly well above all that has been done up to now in this field. Moreover, it deals with a fauna on which we have very few biological data. One hundred nine beetle families are reviewed, from the curious Micromalthidae to the Curculionidae. Mrs. Costa showed me the proofs of the book in 1987 in Sao Paulo, and I had the opportunity then to admire the good quality and even perfection of the drawings.

Book Review: Biologie Des Coleopteres By Renaud Paulian, P. Jolivet

Insecta Mundi

This entirely new book is the first on the biology of beetles since Crowson's book, published in 1981 by Academic Press. This new work in some ways completes Crowson's, but in no way is it a useless repetition. The two books together give a good idea of the biology of this enormous order, here comprising more than 200 families. Paulian's classification is slightly, but not fundamentally, different from Crowson's. There are excellent chapters on endogeous, caverniculous, aquatic, coprophagous, termitophilous, and myrmecophilous beetles. Termitophilous beetles have already been treated well in Termitologia by Grasse (1986, Masson, Paris). Paulian is a well-known …

Identification And Nesting Sites Of North American Species Of Dolichoderus Lund (Hymenoptera: Formicidae), Clifford Johnson

Insecta Mundi

The identification of North American Dolichoderus species by-way-of existing keys is unnecessarily arbitrary and misdeterminations are likely between D. mariae and D. pustulatus, the latter species showing most morphological variation over its range. Diagnoses for the four described species and an undescribed form with a revised key and figures are given to aid entomologists working without identified voucher specimens. Nest data for species other than D. pustulatus in the Coastal Plain revealed below-ground nests or structures immediately at the ground sui-face. Colonies of D. pustulatus in Florida and southern Georgia have arboreal nests in the cavities of smaller limbs …

Book Review: Insect Spiracular Systems By T. B. Nikam And V. V. Khole., V. K. Gupta

Insecta Mundi

The authors and the publisher are to be complimented for the production of this book summarizing the various aspects of the morphology, development and physiology of the insect spiracular systems. Emphasis has been given to those aspects of the insect spiracular systems that have received scant attention so far, like functional morphology and ecophysiological considerations. The role of spiraculo-trachial system thermoregulation has been explained and integrated with the role of haemolymph circulation. The biophysical aspects have been fully explained and integrated with morpho-physiological aspects.

Design And Statistical Analysis Of Plant Protection Experiment, J F. Wallace

All other publications

An Australian co-operation with the national agricultural research project Thailand.

This short course is intended to cover aspects of experimental design, sampling and statistical analysis for researchers in Entomology and Plant Pathology.

The basic principles of experimental design are the same for plant protection research as they are in other areas of research. Problems in plant protection arise from the variation of the data, the complexity of the systems and interactions with environmental factors. In many cases, standard designs are quite adequate.

Scientific Note: Corrections And Clarifications To Endrödi’S The Dynastinae Of The World (Coleoptera: Scarabaeidae), Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

The Dynastinae of the World by the late Sebo Endrodi was published in 1985. This long-awaited book condensed into one English language volume Endrodi's series of 22 principal papers on the entire subfamily Dynastinae. Judging from conversations and correspondence with colleagues, the book has been very well received. . .as well it should have been for it will provide a framework for all future studies on the Dynastinae.

Diversity Of Coprophagous Scarabaeidae (Coleoptera) In Grazed Versus Ungrazed Sandhills Prairie In Western Nebraska, Mary Liz Jameson

University of Nebraska State Museum: Entomology Papers

Baited pitfall traps were used to compare the dung-feeding Scarabaeidae (Coleoptera) of a grazed versus an ungrazed sandhills prairie in western Nebraska. Traps yielded 14,832 coprophagous Scarabaeidae over a 4-week sampling period in 1987. Canthon ebenus (Say), C. pilurarius (L.), Onthophagous hecate Panzer, and O. pennsylvanicus Harold were the dominant species on both prairies. The Shannon-Wiener diversity index indicated that diversity was slightly higher on the grazed site, whereas the Margalef diversity index showed the diversities to be nearly the same. Activity and foraging by scarabs (as measured by trapping success) were found to be most closely correlated with temperature …

Scientific Note: A Case Of Gynandromorphy In Golofa Tersander Burmeister (Coleoptra: Scarabaeidae), Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

Golofa tersander is a sexually dimorphic species with males possessing a long, slender horn arising from the frons, a distinct pronotal tubercle anteriorly, a strongly convex pygidium, and an apically emarginate last sternite. Females, on the other hand, have only a tubercle on the frons, lack a pronotal tubercle, possess a relatively flat pygidium, and the last sternite is entire apically. Both of the specimens described here exhibit all of these external male character states just mentioned.

Hexagenia Mayflies: Biological Monitors Of Water Quality In The Upper Mississippi River, Calvin R. Fremling

Journal of the Minnesota Academy of Science

ABSTRACT-Analysis of Hexageniamayfiy distribution patterns has proven to be a simple, inexpensive method of monitoring water quality in the Upper Mississippi River. Burrowing Hexagenia nymphs live at the mudwater interface intimately associated with organically enriched sediments that have a strong affinity for contaminants. By their presence or absence in silted habitats, they assess the synergistic effects of hypoxia, toxins, and other stresses throughout the year. Adults are large and easily collected, providing inexpensive water quality monitoring on a river so large that comprehensive chemical, physical, and biological analyses are not logistically feasible or affordable. Pollution abatement in metropolitan Minneapolis-St. Paul …

Squash Bugs Of South Dakota, Burruss Mcdaniel

Agricultural Experiment Station Technical Bulletins (1939-2011)

The family Coreidae is best known because of the destructive habit of the squash bug, Anasa tristis, on squash, pumpkin, cucumber, and other members of the cucurbit family in the United States. The family, represented by various species, is found throughout the world. However, only 13 species are found in South Dakota. Lethierry and Severin (1894) supplied us with the earliest and most complete catalog of these bugs. They listed 1,320 species and divided them into 29 subfamilies. Van Duzee (1917), in his catalog of the Hemiptera of America north of Mexico, listed 125 species which he divided among 48 …

Biological Control Of Paterson's Curse, John Dodd, Bill Woods

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

The long- delayed biological control programme for the weed Paterson's curse (Echium plantagineum) has begun with the release of the leaf mining moth (Dialectica scalariella)' an insect slightly bigger than a mosquito. Yhe caterpillar stage of the moth feeds inside the leaves, producing tunnels and chambers which damage the leaf.

The leaf mining moth has already become established in suitable areas. Although the familiar purple haze of Paterson's curse will continue to be seen for years to come, we expect that the leaf mining moth - and other agents yet to be released - will make it a more manageable …

The Queensland Fruit Fly Eradication Campaign, G P. Ayling

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

Western Australia has started an extensive eradication campaign against the Queensland fruit fly, one of the worst horticultural pests in the world.

The programme, the largest of its kind in Australia, and one of the biggest in the world, involves the integration of three tequniques for fruit fly control: lure trapping, protien baiting and the release of sterile male flies.

Potential For Biological Control Of Dendroctonus And Ips Bark Beetles, David Kulhavy, Mitchel C. Miller

Faculty Publications

"The evolution of olfactory communication in bade beetles brought with it the parallel or coevolution of kairomonal systems in the natural enemy complexes. Entomophagous insects developed olfactory receptors and behavioral patterns responsive to insect and host-produced volatiles in the ecosystems of bark beetles. The phenomenon has both positive and negative implications for efforts to employ natural enemies in pest management."
