Pyroghatsiana: A New Genus Of Fire-Colored Beetles (Coleoptera: Pyrochroidae: Pyrochroinae) From The Southern Ghats, India, Daniel K. Young

Insecta Mundi

Pyroghatsiana, a new genus of pyrochroine Pyrochroidae is described from the Southern Ghats of the Indian continental southern tip. The only known specimen is a female, Pyroghatsiana madurensis (Pic), new combination, originally placed in Dendroides Latreille, and subsequently transferred to Pseudodendroides Blair. Several striking differences including the dorsal interocular width between the compound eyes, shape and length of the third antennal segment, and shape of the pronotum preclude placement of Pyroghatsiana in either Dendroides, Pseudodendroides, or any other existing pyrochroine genus.

Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets

Eileen Hebets Publications

Most hypotheses related to the evolution of female-biased extreme sexual size dimorphism (SSD) attribute the differences in the size of each sex to selection for reproduction, either through selection for increased female fecundity or selection for male increased mobility and faster development. Very few studies, however, have tested for direct fitness benefits associated with the latter – small male size. Mecaphesa celer is a crab spider with extreme SSD, whose males are less than half the size of females and often weigh 10 times less. Here, we test the hypotheses that larger size in females and smaller size in males …

Modeling The Geographic Distribution Of Ixodes Scapularis And Ixodes Pacificus (Acari: Ixodidae) In The Contiguous United States, Micah B. Hahn, Catherine S. Jarnevich, Andrew J. Monaghan, Rebecca J. Eisen

Entomology Papers from Other Sources

In addition to serving as vectors of several other human pathogens, the black-legged tick, Ixodes scapularis Say, and western black-legged tick, Ixodes pacificus Cooley and Kohls, are the primary vectors of the spirochete (Borrelia burgdorferi) that causes Lyme disease, the most common vector-borne disease in the United States. Over the past two decades, the geographic range of I. pacificus has changed modestly while, in contrast, the I. scapularis range has expanded substantially, which likely contributes to the concurrent expansion in the distribution of human Lyme disease cases in the Northeastern, North-Central and Mid-Atlantic states. Identifying counties that contain …

Land-Use Change Reduces Habitat Suitability For Supporting Managed Honey Bee Colonies In The Northern Great Plains, Clint R. V. Otto, Cali L. Roth, Benjamin L. Carlson, Matthew D. Smart

Department of Entomology: Faculty Publications

Human reliance on insect pollination services continues to increase even as pollinator populations exhibit global declines. Increased commodity crop prices and federal subsidies for biofuel crops, such as corn and soybeans, have contributed to rapid land-use change in the US Northern Great Plains (NGP), changes that may jeopardize habitat for honey bees in a part of the country that supports >40% of the US colony stock. We investigated changes in biofuel crop production and grassland land covers surrounding ~18,000 registered commercial apiaries in North and South Dakota from 2006 to 2014. We then developed habitat selection models to identify remotely …

The Influence Of Photoperiod On Development Rates Of Three Species Of Forensically Important Blow Flies, M. L. Fisher, Leon G. Higley, John E. Foster

Department of Entomology: Faculty Publications

Environmental factors, such as temperature and photoperiod can play important roles in insect development. Numerous studies have researched insects and their responses to photoperiod, but there has been little research to show if the duration of light alters development rates in blow flies. A review of previous literature revealed differences in the light regime (L:D) reported for the study. This study examined the effects of photoperiod on development rates of Phormia regina Meigen, Cochliomyia macellaria F., and Calliphora vicina Robineau-Desvoidy using four light regimes of 0, 12, 16, and 24 h of light measured at both 20C and 26C. Environmental …

Stress-Induced Changes In Abundance Differ Among Obligate And Facultative Endosymbionts Of The Soybean Aphid, Laramy S. Enders, Nicholas Miller

Department of Entomology: Faculty Publications

Bacterial endosymbionts can drive evolutionary novelty by conferring adaptive benefits under adverse environmental conditions. Among aphid species there is growing evidence that symbionts influence tolerance to various forms of stress. However, the extent to which stress inflicted on the aphid host has cascading effects on symbiont community dynamics remains poorly understood. Here we simultaneously quantified the effect of host-plant induced and xenobiotic stress on soybean aphid (Aphis glycines) fitness and relative abundance of its three bacterial symbionts. Exposure to soybean defensive stress (Rag1 gene) and a neurotoxic insecticide (thiamethoxam) substantially reduced aphid composite fitness (survival 9 reproduction) …

Plant Tolerance: A Unique Approach To Control Hemipteran Pests, Kyle G. Koch, Kaitlin Chapman, Joe Louis, Tiffany Heng-Moss, Gautam Sarath

Department of Entomology: Faculty Publications

Plant tolerance to insect pests has been indicated to be a unique category of resistance, however, very little information is available on the mechanism of tolerance against insect pests. Tolerance is distinctive in terms of the plant’s ability to withstand or recover from herbivore injury through growth and compensatory physiological processes. Because plant tolerance involves plant compensatory characteristics, the plant is able to harbor large numbers of herbivores without interfering with the insect pest’s physiology or behavior. Some studies have observed that tolerant plants can compensate photosynthetically by avoiding feedback inhibition and impaired electron flow through photosystem II that occurs …

Reduced Stability And Intracellular Transport Of Dsrna Contribute To Poor Rnai Response In Lepidopteran Insects, Jayendra Nath Shukla, Megha Kalsi, Amit Sethi, Kenneth E. Narva, Elane Fishilevich, Satnam Singh, Kanakachari Mogilicherla, Subba Reddy Palli

Department of Entomology: Faculty Publications

RNA interference (RNAi) has become a widely used reverse genetic tool to study gene function in eukaryotic organisms and is being developed as a technology for insect pest management. The efficiency of RNAi varies among organisms. Insects from different orders also display differential efficiency of RNAi, ranging from highly efficient (coleopterans) to very low efficient (lepidopterans). We investigated the reasons for varying RNAi efficiency between lepidopteran and coleopteran cell lines and also between the Colorado potato beetle, Leptinotarsa decemlineata and tobacco budworm, Heliothis virescens. The dsRNA either injected or fed was degraded faster in H. virescens than in L. …
