North American Members Of The Hydrellia Crassipes Species Group (Diptera: Ephydridae), D. L. Deonier

Insecta Mundi

The known members of the Hydrellia crassipes species group in North America are described or redescribed, including H. crassipes Cresson, H. procteri Cresson, H. saltator Deonier, H. amplecta n.sp., H. bryani n.sp., H. ocalae n.sp., and H. tibiospica n.sp. Adults of these species exhibit the following synapomorphies: dilated male metafemur and expanded (and flange din some) male metatibia and striate (fibrillate) distiphallus. Only a single species (H. tibiospica n.sp.) was reared from its host-plant species, Juncus debilis Gray, but there are associated habitat data to indicate that the entire species group may have sedges andrushes as host plants.

A Report On A Collection Of Ceratopogonidae (Diptera) From Rondonia (Brazil) And Iquitos (Peru) 1. Tribes Palpomyiini And Stenoxenini, Andrea Dippolito, Gustavo R. Spinelli, Willis W. Wirth

Insecta Mundi

Examination of two large collections of Ceratopogonidae from Rondonia, Brazil, and Loreto, Peru, resulted in records of 15 species in the tribes Palpomyiini and Stenoxenini, including three previously undescribed: Bezzia schmitzorum Dippolito & Spinelli, Palpomyia pseudolacustris D. & S., and Stenoxenus aductus D. & S. from Rondonia.

Nueva Especie De Trientoma (Coleoptera: Tenebrionidae: Trientomini) Para Cuba Con Consideraciones Sobre Otras Especies, Orlando H. Garrido, Esteban Gutierrez

Insecta Mundi

Segun Marcuzzi (1984), hay seis especies de Trientoma en Las Antillas, pero olvidó incluir T. wickhami Casey de Las Bahamas. De esas siete especies, sólo una, se encontraba reportada para Cuba, T. varvasi Solier, 1835. Por lo tanto este género era muy poco conocido y con escasos especímenes depositados en colecciones.

Gundlach, en su colección actualmente depositada en el Instituto de Ecología y Sistemática de la Academia de Ciencias de Cuba, posee solamente tres ejemplares. Con el numero 1567 tiene a Trientoma sp., pero en realidad este ejemplar coincide con el género Trimytantron descrito por Ardoin en 1977. Con el …

Nueva Especie De Loxostethus (Coleoptera: Tenebrionidae: Diaperini) Para Cuba, Orlando H. Garrido, Esteban Gutierrez

Insecta Mundi

El género Loxostethus fue descrito por Triplehorn (1962), describiendo las especies fasciatus y opacifrons para Cuba, jamaicensis para Jamaica, y unicolor para Puerto Rico. Todas fueron halladas en hongos, y si bien no han sido reportadas de la Isla de Santo Domingo no es de extrañar que eventualmente aparezcan. Zayas (1989) describió L. quadrimaculata para Trinidad, Cuba-sin embargo, esta última especie cae dentro de la variación individual de L. fasciatus de acuerdo a la descripción de Triplehorn. Por consiguiente, L. quadrimaculata es sinonimizado bajo Loxostethus fasciatus. Gundlach tiene representado en su colección estos dos taxa bajo el género Cyphiscus …

Bibliography On Hydrellia Griseola Fallen (Diptera: Ephydridae) And Review Of Its Biology And Pest Status, Louis S. Hesler

Insecta Mundi

A bibliography is presented on Hydrellia griseola (FallBn), a cosmopolitan species of shore fly that is an agricultural pest throughout much of its range. The literature review includes 195 references and spans 180 years: from 1813, when H. griseola was first described (as Notophila griseola), to 1993. My review updates and extends by 110 years a previous review of this species. The host plant associations, bionomics, distribution, pest status, and control of this species are reviewed. The known host plants of larval H.griseola are listed. My survey of the literature supports the hypothesis that H. griseola is increasing its …

A Status Report On The Species Of Timarcha (Coleoptera: Chrysomelidae), Pierre Jolivet

Insecta Mundi

The species of Tirnarcha are unique living fossils among the leaf beetles. They walk very slowly, cannot escape by flight, and their majestic bearing can be compared to the Athenian judges, the Timarches. Unfortunately, they are vulnerable to habitat disturbance, insecticides, and environmental changes. Some of the European such as Timarcha tenebricosa and T. goettingensis are becoming more and more rare because of these same habitat changes.

New Locality Records For Bruchidae Of Florida And The West Indies (Coleoptera), John M. Kingsolver

Insecta Mundi

Recent collections have resulted in provisional extensions of distributional ranges of 4 species of Bruchidae. All species of plants listed belong to the Leguminosae (Fabaceae).

Acanthoscelides obvelatus Bridwell was recently intercepted at the Miami, Florida, International Airport infesting Phaseolus spp. beans grown in Haiti and Cuba. Previous records for this bruchid include mainland localities in Mexico, Guatemala, and Colombia. No precise localities in the West Indies are known. These collections indicate that this bruchid is probably established on Hispaniola and Cuba.

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 …

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 …

Specificity Of The Red Imported Fire Ant Phagostimulant Response To Carbohydrates, R. K. Vander Meer, C. S. Lofgren, J. A. Seawright

Entomology Papers from Other Sources

The red imported fire ant, Solenopsis invicta Buren, is considered an oil-loving feeder, however, carbohydrates are essential ingredients in the diet of the fire ant also. Comprehensive screening of mono-, di-, and tri-saccharides demonstrated that glucose, fructose, fucose, sucrose, maltose, turanose and raffinose were significant phagostimulants for fire ant workers. It was also found that while D-glucose and L-fucose, the naturally occurring isomers, were active, the opposite diastereomers were not. Any structural modification of the glucose molecule resulted in loss of activity. None of the sugar alcohols evaluated were active. The fire ant is an agricultural pest and the many …
