Testing The Hypothesized Antipredator Defence Function Of Stridulation In The Spiny Orb-Weaving Spider, Micrathena Gracilis, Tyler B. Corey, Eileen A. Hebets

Eileen Hebets Publications

The observable diversity of antipredator defenses across organisms demonstrates predation’s impact on trait evolution. The functions of many traits that are presumed to have an antipredator function have never been directly tested. The spiny orb-weaving spider, Micrathena gracilis, for example, stridulates when grasped. While stridulation was first hypothesized to be an antipredator defense nearly 50 years ago, no data exist to support this hypothesis. To explore the form and function of M. gracilis stridulation, we first quantified the behavioral and acoustical properties of sound production. Next, using laboratory assays, we directly tested the effect of stridulation on survival with …

First Record For Cypherotylus Dromedarius (Lacordaire) (Coleoptera: Erotylidae) From Panama, Brian J. Armitage, Alonso Santos Murgas

Insecta Mundi

Cypherotylus dromedarius (Lacordaire, 1842) (Coleoptera: Erotylidae) was described from French Guiana. Information about its current distribution is scattered throughout the literature and the internet. Specimens of this species were recently observed and photographed in the Boquete area, Chiriqui Province, Panama, and constitute a new record for the country of this species. Subsequently, we located two specimens deposited in the National Reference Collection of the G. B. Fairchild Museum of Invertebrates, University of Panama, from the same locality in Chiriqui Province. We summarize the distribution of this species from scattered sources and provide five new records.

The Genus Ochodaeus In Italy: Taxonomy And Distribution (Coleoptera: Scarabaeoidea: Ochodaeidae), Stefano Ziani

Insecta Mundi

The author provides a taxonomic, nomenclatural and distributional review of the genus Ochodaeus Dejean, 1821 (Coleoptera: Scarabaeoidea: Ochodaeidae) in Italy. All Italian populations have been confirmed to belong to a single species, O. chrysomeloides (Schrank, 1781). After the study of a syntype, O. cychramoides Reitter, 1892, formerly considered an Italian endemic, is confirmed to be a junior synonym of O. chrysomeloides. Type material of O. chrysomeloides is believed to be destroyed, therefore a neotype is here designated and deposited at the Natural History Museum of Vienna, Austria. A lectotype is here designated for O. cychramoides and deposited in the Hungarian …

New Records Document Cystiphora Sonchi (Vallot) (Diptera: Cecidomyiidae) And Associated Parasitoids (Hymenoptera) In The Continental United States, Louis S. Hesler, Michael W. Gates, Eric A. Beckendorf

Insecta Mundi

A gall midge, Cystiphora sonchi (Vallot, 1827) (Diptera: Cecidomyiidae), is reported for the first time in the continental United States of America from the states of Minnesota, North Dakota, and South Dakota. The gall midge is an obligate parasite of Sonchus L., including perennial sowthistle, Sonchus arvensis L., a weed that was the impetus for earlier releases of C. sonchi as a biological control in Canada. Patches of S. arvensis were commonly infested with C. sonchi, and often leaves were densely galled. Dissections of galled leaves led to the novel finding of multiple C. sonchi larvae in some individual …

Interplay Of Phytohormones Facilitate Sorghum Tolerance To Aphids, Sajjan Grover, Earl Agpawa, Gautam Sarath, Scott E. Sattler, Joe Louis

Department of Entomology: Faculty Publications

Key message -- Interactions among phytohormones are essential for providing tolerance of sorghum plants to aphids.

Plant’s encounter with insect herbivores trigger defense signaling networks that fine-tune plant resistance to insect pests. Although it is well established that phytohormones contribute to antixenotic- and antibiotic-mediated resistance to insect pests, their role in conditioning plant tolerance, the most durable and promising category of host plant resistance, is largely unknown. Here, we screened a panel of sorghum (Sorghum bicolor) inbred lines to identify and characterize sorghum tolerance to sugarcane aphids (SCA; Melanaphis sacchari Zehntner), a relatively new and devastating pest of sorghum in …

Many species of plants and a few species of animals are believed to have resulted from hybridization of parental species, and the ability of species to occasionally hybridize in captivity and in nature is even more widespread. In the present study, we describe a hybridization experiment conducted in the laboratory between the sexually dimorphic Automeris io (Fabricius), a widespread, variable species ranging from Canada to Costa Rica, and its congener A. louisiana (Ferguson and Brou), a more local, sexually monomorphic species (Lepidoptera: Saturniidae). The A. louisiana populations occur in a highly specialized habitat—the coastal marshland along the Gulf of Mexico …

Systematic Status Of The Chilean Genus Carlota Arias-Bohart, 2014 (Coleoptera: Elateridae: Agrypninae: Agrypnini), Elizabeth T. Arias-Bohart

Insecta Mundi

The click beetle genus Carlota Arias-Bohart (Coleoptera: Elateridae: Agrypninae: Agrypnini) was considered as a junior synonym of Candanius Hayek recently. However, there are deep morphological differences between these genera which justify the validity of Carlota. The morphology of this genus was re-examined in detail and based on the short and shallow antennal grooves, strongly serrate antennae from antennomeres 3 through 10, subquadrate pronotum with four distinct subcircular depressions, and straight prosternal process not bent dorsally, I resurrect the genus Carlota from synonymy.
