Feeding Behavior Of Nephotettix Virescens (Homoptera: Cicadellidae) On Rice Varieties With Different Levels Of Resistance, H. R. Rapusas, E. A. Heinrichs

Department of Entomology: Faculty Publications

The feeding behavior of Nephotettix virescens (Distant) on rice varieties with different levels of resistance was studied using an AC electronic monitor for insect feeding (EMIF) system. Varieties used were TN1 (susceptible), IR36 (moderately resistant), and ASD7, IR60, and IR64 (resistant). Six typical waveforms were recorded, and each type corresponded to a certain activity of the insect during the feeding process as indicated by histological sections of the leaf observed. Significantly more phloem feeding was observed on the susceptible plants than on the moderately resistant and resistant plants. Fifty percent of the total test period was spent feeding on the …

Oaxacanthaxia Viridis, A New Genus And Species (Coleoptera: Buprestidae) From Mexico With Old World Affinities, C. L. Bellamy

Insecta Mundi

A new genus and species, Oaxacanthaxia viridis, is described from the Mexican state of Oaxaca. The genus is distinguished in a key to the related taxa from Mesoamerica and tabularly from the Old World Philanthaxia, its putative sister genus. A brief discussion is given towards placing this new genus within the tribe Anthaxiini sensu Holynski. Philanthaxina Holynski is reduced to junior synonymy of Thomassetiina Bellamy, stat. nov.

North American Negastriinae (Coleoptera, Elateridae): The Negastriinae Of The Eastern United States And Adjacent Canada, Jeffrey N. L. Stibnick

Insecta Mundi

Eighteen species of Negastriinae (Coleoptera, Elateridae) from Eastern North America are keyed, with illustrations, diagnoses and maps for all species. Included are five new species: Negastrius arnetti, Paradonus beckeri, P. illinoiensis, P. jerseiensis and P. olivereae. One name, Negastrius exiguus (Randall) is restored from synonymy. Four species, Negastrius extricatus (Fall), Neohypdonus aestivus (Horn), Neohypdonus restrictulus (Mannerheim) and Paradonus obliquatulus (Melsheimer) represent new combinations. Illustrations of the male genitalia of all species and representative female genitalia of each genus are given.

Editorial, Ross H. Arnett Jr.

Insecta Mundi

For several months in 1984 Robert E. Woodruff and I discussed the need for a new entomological journal. Naturally we were concerned about the literally hundreds of existing journals devoted to entomology in general and specific groups of insects in particular. (I had recently compiled, still unpublished, a directory of the entomological serial publications of the World.) We, therefore, searched and found an unoccupied niche for our new journal. We started Insecta Mundi, with the help of a local editorial board, in 1985. The first volume took two years to complete. (See p. 132 for publication dates of each …

Distributional, Biological And Taxonomic Notes On North American Buprestidae (Coleoptera), Richard L. Westcott

Insecta Mundi

Distributional, biological and taxonomic data are provided for 64 species of Buprestidae belonging to the genera Acmaeodera, Acmaeoderoides, Actenodes, Agaeocera, Agrilus, Buprestis, Chrysophana, Descarpentriesina, Dicerca, Hippomelas, Melanophila, Pachyschelus, Polycesta, Ptosima, Spectralia, Taphrocerus, Trachykele and Tyndaris. Forty-six of these species are recorded for the first time from a state or province, and new larval host records are provided for 15 others. Taphrocerus sulcifrons Fisher is recorded from the U.S. for the first time. Evidence is given to eliminate the recorded occurrence of Agrilus arbuti Fisher in British Columbia and Ptosima walshii LeConte in California.

Systematic Study Of The Pantomorus Viridisquamosus Species Group (Coleoptera: Curculionidae), Analia Lanteri, Marta S. Loiacono

Insecta Mundi

The Pantomorus viridisquamosus species group can be separated from other Pantomorus Schoenherr, because it has recumbent setae, slender antennae with funicular article 2 almost as long as 1, glabrous scutellum, indistinct humeri, and hind tibiae lacking corbel plate and with dorsal comb about as long as apical comb. It is composed of two species, P. viridisquamosus (Boheman) from central and northeastern Argentina, Uruguay, and southern Brazil, and P. obrieni Lanteri sp.nov. from northeastern Argentina and southern Brazil. Pantomorus obrieni differs from P. viridisquamosus because it is smaller and has carinate scales, shorter and wider setae, more conical rostrum, and more …

Cycloalexy: A New Concept In The Larval Defense Of Insects, Pierre Jolivet, Joao Vasconcellos-Neto, Philip Weinstein

Insecta Mundi

Anyone who has ever seen a Western will be familiar with the defensive tactics employed by the pioneers: The wagon train is formed into a ring, women and children on the inside, with the men firing out at the circling Indians. The larvae of some Coleoptera and Hymenoptera have long employed similar tactics, in defense against their predators (ants, bugs) and parasitoids (wasps, flies).

Tetrigidae (Orthoptera) With Partly Exposed Wings, R. E. Blackith

Insecta Mundi

Long series of some species of Tetrigidae from south Asia show that the wings regularly project beyond the pronotal shield by some 15- 35 percent of their length, depending on the species. There is little intraspecific variation and alary polymorphism is not normally detectable. The role of such exposed wings is discussed and one new species is described. Most such species probably owe their evident relationship to evolution prior to the disintegration of the Gondwanaland super-continent.

A Catalog Of The Order Zoraptera (Insecta), Michael D. Hubbard

Insecta Mundi

Apionidae From North And Central America. Part 2. Description Of A New Subgenus And Two New Species Of Apion From Mexico (Coleoptera), David G. Kissinger

Insecta Mundi

A new subgenus, Xixias (type species Apion herculanum Smith), is described for the Apion herculanum group and the Apion peculiare group formerly assigned to the Apion subgenus Ixias Sainte-Claire Deville. Unique features within Apionidae are the structure of the endophallus and the host plant families Caprifoliaceae and Rutaceae. A. nigrosparsum Suffrian formerly included in the peculiare group is excluded. Two new species described from Mexico, Apion clarki Kissinger and A. hahowdeni Kissinger, are the first North American Apion with tuberculate elytra. Supplemental descriptions and/or distribution records are given for Apion americanum Wagner, Apion basirostre Sharp, Apion lebasii Gyllenhal, Apion harpax …
