Detection And Epidemic Dynamic Of Tocv And Ccyv With Bemisia Tabaci And Weed In Hainan Of China, Xin Tang, Xiaobin Shi, Deyong Zhang, Fan Li, Fei Yan, Youjun Zhang, Yong Liu, Xuguo Zhou

Entomology Faculty Publications

Background: In recent years, two of the crinivirus, Tomato chlorosis virus (ToCV) and Cucurbit chlorotic yellows virus (CCYV) have gained increasing attention due to their rapid spread and devastating impacts on vegetable production worldwide. Both of these viruses are transmitted by the sweet potato whitefly, Bemisia tabaci (Gennadius), in a semi-persistent manner. Up to now, there is still lack of report in Hainan, the south of China.

Methods: We used observational and experimental methods to explore the prevalence and incidence dynamic of CCYV and ToCV transmitted by whiteflies in Hainan of China.

Results: In 2016, the chlorosis symptom was observed …

Daily Eclosion Pattern Of The Saratoga Spittlebug, Aphrophora Saratogensis (Fitch) (Homoptera: Cercopidae), Louis F. Wilson, Patrick C. Kennedy

The Great Lakes Entomologist

The Saratoga spittlebug, Aphrophora saratogensis (Fitch), is a destructive pest of young planted pines in the Lake States. The adults injure the pines by feeding on the sap of branches. However, nymphs feed on the sap of alternate host plants, which include many herbs and woody plants on the forest floor. Our studies show that the time of the eclosion and shortly thereafter is one of the most vulnerable periods in the insect's life cycle. During this period the nymphs must free themselves from the eggs that are on pine buds, vacate the pines, search out suitable host plants on …

Within-Tree Distribution Of The Jack Pine Tip Beetle, Conophthorus Banksianae Mcpherson, On Jack Pine, David J. Hall, Louis F. Wilson

The Great Lakes Entomologist

The jack pine tip beetle (Conophthorus banksianae McPherson) attacks the shoot tips of jack pine (Pinus banksiana Lamb.) and other pines, killing the apical one inch of the shoot and thus causing crooks and forks in the branches and main stem. Several recent studies on the insect have present the bionomics, host relations, and mortality (McPherson, Wilson, and Stehr, 1970; McPherson, Stehr, and Wilson, 1970; Hall and Wilson, 1974), as part of a project to learn its importance to the forest resource and to seek potential control methods. In the part of the study reported here we wanted to know …

Injury To Aldrin-Treated And Untreated Red Pine By White Grubs (Coleoptera: Scarabaeidae) And Other Agents During First Five Years After Planting, Richard F. Fowler, Louis F. Wilson

The Great Lakes Entomologist

Freshly planted red pine (Pinus resinosa Ait.) seedlings are vulnerable to injury by several agents. White grubs -- the larvae of May beetles (Phyllophaga spp.) -- are among these agents and sometimes must be controlled in areas scheduled for pine planting. A study was begun in 1967 to evaluate the effectiveness of applying three levels of aldrin for controlling white grubs in the Upper Peninsula of Michigan. After two years white grubs were satisfactorily suppressed by the three treatments tested (Fowler and Wilson 1971a). Reported here is a continuation of that study for five years following planting. We wanted to …

North American Species Of The Genus Axonopsis (Acarina: Aturidae: Axonopsinae), David R. Cook

The Great Lakes Entomologist

(excerpt) Members of the genus Axonopsis have a broad zoogeographic distribution but are unreported from the Australian region and South America south of Colombia. Species occur in permanent standing waters and streams (including interstitial water). Representa- tives of four subgenera, Axonopsis s. s., Brachypodopsis, Paraxonopsis and Vicinaxonopsis, have been collected in North America, and a species of the closely related genus Erebaxonopsis is also known from interstitial waters in California. The only anomalous aspects of the distributional patterns are the apparent absence of Hexaxonopsis (which has a relatively widespread Palearctic range) and the stream (and interstitial) habitat of the North …

Effects Of A Prescribed Burn On The Adult Butterfly Assemblage Of A Coastal Grassland, J. Nicole Desha, Joseph Colbert, Kimberly M. Andrews, Scott Coleman, C. Tate Holbrook

Georgia Journal of Science

Coastal grasslands are globally threatened by development and natural succession. In the southeastern United States, these increasingly rare ecosystems are being managed using prescribed fire, but ecological responses to fire management are largely unknown, particularly among nontargeted species. We tested for short-term effects of controlled burning on the abundance and species richness of adult butterflies, which utilize coastal grasslands for nectaring resources and as migratory stopover sites. In February 2015, four plots of coastal grassland on Little St. Simons Island, GA were burned and paired with unburned (control) plots of equal size. Throughout the following summer-fall flight season, we conducted …

Economic Injury Levels For Aphis Glycines Matsumura (Hemiptera: Aphididae) On The Soybean Aphid Tolerant Ks4202 Soybean, Lia Marchi-Werle, Edson L.L. Baldin, Hillary D. Fischer, Tiffany Heng-Moss, Thomas Hunt

Department of Entomology: Faculty Publications

The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is an invasive species from Asia that has been the major economic insect pest of soybeans, Glycine max (L.) Merrill, since 2000. While use of soybeans expressing antibiosis and antixenosis is a well-studied strategy to manage this pest, aphid-tolerant soybeans remain underexplored. This study examined the relationship between cumulative aphid-days (CAD) and yield loss in the tolerant soybean KS4202 during two growing seasons to determine the economic injury levels (EILs) for soybean aphids on KS4202. Soybean aphid infestations were initiated during the soybean reproductive stages. A range of CAD treatments (3,000–45,000 CADs) …

Impact Of Habitat Degradation On Species Diversity And Nest Abundance Of Five African Stingless Bee Species In A Tropical Rainforest Of Kenya, Nkoba Kiatoko, Suresh Kumar Raina, Frank Van Langevelde

All Peer-Reviewed Publications

Natural habitat degradation often involves the reduction or disappearance of bee species. In Africa, stingless bees are hunted for honey, which is used as food, for medicinal purposes, and for traditional rituals. Severe habitat degradation due to human settlement is hypothesized to have a negative impact on the species diversity of the African stingless bee species. In this paper, we assess the impact of habitat degradation on the diversity of five stingless bee species across different habitats in the tropical rainforest of Kenya (indigenous forest, mixed indigenous forest) and its neighbouring landscape (grassland, village) in western Kenya. The species fauna, …

The Impact Of Hive Type On The Behavior And Health Of Honey Bee Colonies (Apis Mellifera) In Kenya, Alexander Mcmenamin, Fiona Mumoki, Maryann Frazier, Joseph Kilonzo, Bernard Mweu, Tracey Baumgarten, Harland Patch, Baldwyn Torto, Daniel Masiga, James Tumlinson, Christina Grozinger, Elliud Muli

All Peer-Reviewed Publications

There has been a long-standing interest in developing approaches to maximize honey production by Kenyan beekeepers. Since honey bees in Kenya are passively managed, the main decision beekeepers make is which hive type to use: traditional Log hives, Langstroth hives, and Kenyan top-bar hives. We found Langstroth hives to be the most attractive to migrating swarms, followed by Log hives, while Kenyan top-bar hives were the least preferred. Pathogen and parasite loads correlated only with colony age and absconding rates were associated only with colony size and weight. We recommend additional studies to understand the factors that drive swarm attraction …

Impact Of Introduced Parasitoid Cotesia Vestalis (Hymenoptera: Braconidae) On Plutella Xylostella (Lepidoptera: Plutellidae) And Its Parasitoid Guild On Kale In Semi-Arid Areas In Kenya, Ruth Kahuthia-Gathu, Brigitte Nyambo, Sevgan Subramanian

All Peer-Reviewed Publications

Cotesia vestalis was introduced into Kenya from South Africa in March 2003 for biological control of Plutella xylostella with initial release in 2004. To confirm establishment, the rate of spread beyond the release sites and parasitism rates by C. vestalis were assessed between October 2011 and April 2012 in eastern and southeastern Kenya (Kitui, Mwingi/Yatta and Loitokitok areas). Monthly observations on kale infestation by diamondback moth, damage scores, parasitism and parasitoid guild were undertaken on 20 randomly selected plants in farmer-managed kale farms. Sampled larval and pupal stages were placed in containers and taken to the laboratory for parasitoid emergence. …

An Assessment Of The Magnitudes And Factors Associated With Postharvest Losses In Off-Farm Grain Stores In Kenya, Joseph K. Mwangi, Christopher M. Mutungi, Soul Kifouly G. Midingoyi, Abdul K. Faraj, Hippolyte D. Affognon

All Peer-Reviewed Publications

Off-farm grain storage is an important postharvest undertaking by government, traders and processors in Kenya. A survey was conducted in 2014/2015 to assess the kinds and magnitudes of perceived losses experienced in off-farm stores, and the factors associated with them. Store supervisors or key personnel charged with grain storage in 39 public and 74 private stores, spread across the six maize growing agro-ecological zones, were interviewed using a structured questionnaire. Total perceived losses averaged 17.6± 2.3%, and were attributed to insects (7.2± 1.0%), molds (5.7± 2.1%), moisture loss (3.4± 0.5%), rodents (2.0± 0.5%), spillage (0.50 ± 0.0%) and birds (0.10± …

The Mecoptera Of Michigan, Albert R. Thornhill, James B. Johnson

The Great Lakes Entomologist

(excerpt) To date, no one has published on the Mecoptera of Michigan. A comprehensive taxonomic paper on the Mecoptera of Illinois, by Donald W. Webb, Illinois Natural History Survey, and Norman D. Penny, University of Kansas, is in preparation and will include keys to and descriptions of the midwestern species of Mecoptera. It is hoped that the present paper will supplement the publication by Webb and Penny and enable interested persons in Michigan to easily identify adult Mecoptera.

The Etymology Of The Names Pipunculus Latreille And Dorilas Meigen (Diptera, Pipunculidae), H. D. Cameron

The Great Lakes Entomologist

(excerpt) There are at least two good reasons for understanding the etymology of scientific names. The first is to satisfy the natural curiosity about the history of the terms we use, and to gain an entree into the mind of the man ~.ho fist used a name. A study of Fabricius' names, for instance, reveals that he had a playful sense of humor. Secondly, such understanding contributes to the stability of names, and helps to prevent irresponsible emendation of spelling, gender, or morphology such as burden the synonomies of most groups. It is happily

Similarities In Evasive Behavior Of Wolf Spiders (Araneae: Lycosidae), American Toads (Anura: Bufonidae) And Ground Beetles (Coleopterea: Carabidae), Lauren E. Brown, James H. Thrall

The Great Lakes Entomologist

(excerpt) While collecting newly metalnorphosed American toads, Bufo anlericanus Holbrook, we have observed that they exhibited evasive behavior similar to that of adults of the wolf spiders, Pardosa saxatilis (Hentz), Pirata insularis Emerton, Pirata arerzicola Emerton, Pirata piratica (Oliver), and adults of the ground beetle, Elaplrrus ruscarius Say. When pursued or disturbed, the spiders, beetles and toads ran across the pound rapidly for short distances (ca. 1-50 cm). They then stopped abruptly and remained motionless. If they were further pursued, this escape sequence was repeated in the same or another direction. Toads and spiders occasionally moved to shallow water to …

A Flexible Computer Program For The Production Of Insect Labels, Carl W. Albrecht, Russell V. Skavaril

The Great Lakes Entomologist

(excerpt) In many instances multiple copies of identical insect labels are needed, either with or without blank spaces, for the purpose of placing collection or determination data with a specimen. One of several ways to produce acceptable insect labels is through the photo-reduction of typewritten copy. Compared to type setting, followed by press printing, this method provides greater flexibility, and often quicker results, especially when labels are needed only in relatively small quantities; also, it may be less expensive than press printing. However, the typing of full sheets of photo-ready copy is a tedious and time consuming process. If one …
