Effect of Crop Volume on Contraction Rate in Adult House Fly
Authors:  Stoffolano, John G.; Patel, Bhavi; Tran, Lynn
Source: Annals of the Entomological Society of America, Volume 107, Number 4, July 2014, pp. 848-852(5)
Abstract:  The functional aspects of the adult house fly crop have not been studied even though various human and domestic animal pathogens have been discovered within the crop lumen. The average volume consumed (midgut and crop) by flies starved for 24 h was 3.88 ?l by feeding both sexes on a sucrose phosphate glutamate buffer. In addition, various volumes of a solution (0.125 M sucrose plus Amaranth dye) were fed to 3-d-old adult female house flies... (Click here for full abstract)

The Relationship Between Deer Density, Tick Abundance, and Human Cases of Lyme Disease in a Residential Community
Authors:  Kilpatrick, Howard J.; Labonte, Andrew M.; Stafford, Kirby C.
Source: Journal of Medical Entomology, Volume 51, Number 4, Pages 725-906, pp. 777-784(8)
Abstract:  White-tailed deer ( Odocoileus virginianus Zimmerman), serve as the primary host for the adult blacklegged tick ( Ixodes scapularis Say), the vector for Lyme disease, human babesiosis, and human granulocytic anaplasmosis. Our objective was to evaluate the degree of association between deer density, tick abundance, and human cases of Lyme disease in one Connecticut community over a 13-yr period. We surveyed 90-98% of all permanent residents in the community six times from 1995 to 2008... (Click here for full abstract

X-Ray-Induced Sterility in Aedes albopictus (Diptera: Culicidae) and Male Longevity Following Irradiation
Authors:  Yamada, H.; Parker, A. G.; Oliva, C. F.; Balestrino, F.; Gilles, J.R.L.
Source: Journal of Medical Entomology, Volume 51, Number 4, Pages 725-906, pp. 811-816(6)
Abstract:  The mosquito Aedes albopictus (Skuse, 1895) is a potent vector of several arboviral diseases, most notably chikungunya and dengue fever. In the context of the sterile insect technique (SIT), the sterilization of the male mosquitoes before their release can be achieved by gamma-ray irradiation. As gamma-ray irradiators are becoming increasingly problematic to purchase and transport, the suitability of an X-ray irradiator as an alternative for the sterilization of Ae. albopictus males was studied...

Exploring New Thermal Fog and Ultra-Low Volume Technologies to Improve Indoor Control of the Dengue Vector, Aedes aegypti (Diptera: Culicidae)
Authors:  Harwood, James F.; Farooq, Muhammad; Richardson, Alec G.; Doud, Carl W.; Putnam, John L.; Szumlas, Daniel E.; Richardson, Jason H.
Source: Journal of Medical Entomology, Volume 51, Number 4, Pages 725-906, pp. 845-854(10)
Abstract:  Control of the mosquito vector, Aedes aegypti (L.), inside human habitations must be performed quickly and efficiently to reduce the risk of transmission during dengue outbreaks. As part of a broad study to assess the efficacy of dengue vector control tools for the U.S. Military, two pesticide delivery systems (ultra-low volume [ULV] and thermal fog) were evaluated for their ability to provide immediate control of Ae. aegypti mosquitoes with a contact insecticide inside simulated urban structures...

Alate Trap-Based Assessment of Formosan Subterranean Termite (Isoptera: Rhinotermitidae) Dispersal Flight Phenology Associated With an Urbanized Barrier Island Ecosystem
Authors:  Puckett, Robert T.; Espinoza, Elida M.; Gold, Roger E.
Source: Environmental Entomology, Volume 43, Number 4, August 2014, pp. 868-876(9)
Abstract:  During 2009, 2010, and 2011, the reproductive dispersal flight phenology of Formosan subterranean termites ( Coptotermes formosanus Shiraki) was assessed on Galveston Island, TX, via LED light-based termite alate traps. In all three years, traps were deployed at sampling sites before the initiation of C. formosanus dispersal flights, and retrieved weekly until the cessation flights. In total, 45, 102, and 90 traps were deployed during 2009, 2010, and 2011, respectively... (Click here for full abstract

Effect of Broadcast Baiting on Abundance Patterns of Red Imported Fire Ants (Hymenoptera: Formicidae) and Key Local Ant Genera at Long-Term Monitoring Sites in Brisbane, Australia
Authors:  McNaught, Melinda K.; Wylie, F. Ross; Harris, Evan J.; Alston, Clair L.; Burwell, Chris J.; Jennings, Craig
Source: Journal of Economic Entomology, Volume 107, Number 4, August 2014, pp. 1307-1315(9)
Abstract:  In 2001, the red imported fire ant ( Solenopsis invicta Buren) was identified in Brisbane, Australia. An eradication program involving broadcast bait treatment with two insect growth regulators and a metabolic inhibitor began in September of that year and is currently ongoing. To gauge the impacts of these treatments on local ant populations, we examined long-term monitoring data and quantified abundance patterns of S. invicta and common local ant genera using a linear mixed-effects model...

Potential Distribution and Cost Estimation of the Damage Caused by Cryptotermes brevis (Isoptera: Kalotermitidae) in the Azores
Authors:  Guerreiro, O.; Cardoso, P.; Ferreira, J. M.; Ferreira, M. T.; Borges, P.A.V.
Source: Journal of Economic Entomology, Volume 107, Number 4, August 2014, pp. 1554-1562(9)
Abstract:  In the Azores archipelago, a significant proportion of buildings are infested with the urban exotic drywood termite Cryptotermes brevis (Walker), causing major economical and patrimonial losses. This work aims to understand the potential spread of this termite species in the Azores and estimate the costs for both treatment and reconstruction of infested buildings in the entire archipelago. A maximum entropy niche modeling process was used to determine the potential occurrence... (Click here for full abstract

Mortality Patterns in Coptotermes gestroi (Blattodea: Rhinotermitidae) Following Horizontal Transfer of Nonrepellent and Repellent Insecticides: Effects of Donor:Recipient Ratio and Exposure Time
Authors:  Neoh, Kok-Boon; Yeoh, Boon-Hoi; Lee, Chow-Yang
Source: Journal of Economic Entomology, Volume 107, Number 4, August 2014, pp. 1563-1572(10)
Abstract:  The donor: recipient ratio and the time of donor exposure to termiticide required for maximal toxicant transfer among termites are crucial information for the development of termite management plans. Most of the available information on termiticide toxicity came from temperate zonal termite species, whereas little is known about tropical Asian species. In this study, mortality patterns of recipient termites, Coptotermes gestroi (Wasmann) subjected to seven formulated insecticide exposures under different... (Click here for full abstract

Lethal and Sublethal Effects of Lufenuron on the Formosan Subterranean Termite (Isoptera: Rhinotermitidae)
Authors:  Wang, Cai; Henderson, Gregg; Gautam, Bal K.; Chen, Xuan
Source: Journal of Economic Entomology, Volume 107, Number 4, August 2014, pp. 1573-1581(9)
Abstract:  A laboratory study was conducted to understand the effect of low concentrations of lufenuron on termite physiology and behavior. Survivorship, running speed, body water content, food consumption, tunneling, microbial infection, and two behavioral patterns (carcass-burying behavior and particle transport behavior) were compared among Formosan subterranean termites, Coptotermes formosanus Shiraki, fed lufenuron-treated (250, 500, or 1,000 ppm) or untreated (control) filter paper...

Fumigation of Bed Bugs (Hemiptera: Cimicidae): Effective Application Rates for Sulfuryl Fluoride
Authors:  Phillips, Thomas W.; Aikins, Michael J.; Thoms, Ellen; Demark, Joe; Wang, Changlu
Source: Journal of Economic Entomology, Volume 107, Number 4, August 2014, pp. 1582-1589(8)
Abstract:  The bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), has resurged recently as a domestic pest in North America with very limited options for decisive control. We report efficacy studies with sulfuryl fluoride (SF) toward use as a structural fumigant to control bed bugs. Laboratory studies were conducted in which eggs, adults, and nymphs from a pesticide susceptible laboratory population were fumigated for 24 h using SF at 99.8% purity in airtight, 3.8-liter glass containers under two temperatures, 25°C and 15°C....

Authors:  Anikwe, Joseph Chuks; Adetoro, Fouad Abidemi; Anogwih, Joy Anuri; Makanjuola, Winifred Ayinke; Kemabonta, Kehinde Abike; Akinwande, Kayode Lawrence
Source: Journal of Economic Entomology, Volume 107, Number 4, August 2014, pp. 1639-1642(4)
Abstract:  Indoxacarb gel bait was evaluated for its efficacy in the laboratory and field against American cockroaches, Periplaneta americana (L.), and German cockroaches, Blattella germanica (L.). Advion 0.6% indoxacarb gel bait was toxic to both P. americana and B. germanica. There were no significant differences in the LT50 (h) values for treatment levels of 0.25 g, 0.5 g, and 1.0 g gel applied against P. americana, whereas gel applied at 0.5 g to B. germanica had...
