A Periodic
ESA E-mail Service to ACEs and Urban-Industrial BCEs
The Entomological Society of America is the #1 source of
scientific information for the entomologically-focused urban professional. This
email is a service of the ESA for all ACEs and any BCEs who hold a specialty in
urban and industrial entomology.
Here is a summary of some recent articles in the ESA
journals that relate to structural pest management and urban arthropod pests.
The abstracts are freely available online for all articles, though access to
the full text will generally require member in the ESA, in addition to your
certification.
Crop-Emptying Rate and the Design of Pesticide Risk
Assessment Schemes in the Honey Bee and Wild Bees (Hymenoptera: Apidae)
Authors: Fournier, Alice; Rollin, Orianne; Le Féon,
Violette; Decourtye, Axel; Henry, Mickaël
Abstract: Recent scientific literature and
reports from official sanitary agencies have pointed out the deficiency of
current pesticide risk assessment processes regarding sublethal effects on
pollinators. Sublethal effects include troubles in learning performance,
orientation skills, or mobility, with possible contribution to substantial
dysfunction at population scale. However, the study of sublethal effects is
currently limited by considerable knowledge gaps ... (

Pheromone-Assisted Techniques to Improve the
Efficacy of Insecticide Sprays Against Linepithema humile (Hymenoptera:
Formicidae)
Authors: Choe, Dong-Hwan; Tsai, Kasumi; Lopez, Carlos M.;
Campbell, Kathleen
Source: Journal of Economic Entomology, Volume 107, Number
1, February 2014
Abstract: Outdoor residual sprays are among the
most common methods for targeting pestiferous ants in urban pest management
programs. If impervious surfaces such as concrete are treated with these
insecticides, the active ingredients can be washed from the surface by rain or
irrigation. As a result, residual sprays with fipronil and pyrethroids are
found in urban waterways and aquatic sediments. Given the amount of
insecticides applied to urban settings for ant control ... (

Field and Laboratory Efficacy of Three Insecticides
for Population Management of the Asian Cockroach (Dictyoptera: Blattellidae)
Authors: Snoddy, Edward T.; Appel, Arthur G.
Abstract: Toxicity, repellency, and performance
of three insecticides, ?-cyfluthrin EC, fipronil granules, and an essential oil
EC formulation, were evaluated against the Asian cockroach,
Blattella
asahinai Mizukubo, in field and laboratory experiments. The ?-cyfluthrin
EC and fipronil granules were significantly more toxic than the essential oil
EC formulation under continuous exposure conditions, with LT50 values of 0.014,
0.45, and 11.45 d, respectively. The ?-cyfluthrin EC and fipronil granules were
also significantly more toxic (

Spatial Pattern in Aerosol Insecticide Deposition
Inside a Flour Mill
Authors: Campbell, James F.; Arthur, Frank H.; Zhu, Kun Yan
Abstract: Aerosol insecticides are commonly
used for management of stored-product pests inside food facilities, but the
physical complexity of the interior of most food facilities may influence the
dispersal and deposition of droplets and create spatial variation in dosage.
The spatial pattern in aerosol deposition was evaluated inside a flour mill
using a high density grid of bioassay insects. Three insecticides, Aerotech
with NyGuard and Pyrocide 100 + Diacon II ... (

An Inexpensive Feeding Bioassay Technique for
Stored-Product Insects
Authors: Clark, Erin L.; Isitt, Rylee; Plettner, Erika;
Fields, Paul G.; Huber, Dezene P.W.
Abstract: We used the red flour beetle,
Tribolium
castaneum Herbst (Coleoptera: Tenebrionidae), to compare three feeding
bioassay techniques using flour disks. The area (scanner or digital
photographs) and mass (sensitive balance) of the same flour disks were measured
daily for 1 or 2 wk to assess feeding by insects. The loss in mass and area
over 4 h was measured, as some variation over time was noticed in the disks
with no insects feeding on them. ... (

Evaluation of Synergized Pyrethrin Aerosol for
Control of Tribolium castaneum and Tribolium
confusum (Coleoptera: Tenebrionidae)
Authors: Kharel, Kabita; Arthur, Frank H.; Zhu, Kun Yan;
Campbell, James F.; Subramanyam, Bhadriraju
Abstract: Aerosol insecticides are being used in flour
mill pest management programs, but there is limited information on their
efficacy on different insect life stages. In this study, we evaluated the
efficacy of synergized pyrethrin applied as an aerosol against eggs, larvae,
pupae, and adults of the red flour beetle, Tribolium castaneum (Herbst), and
the confused flour beetle, Tribolium confusum Jacquelin du Val. Effects of
direct and indirect exposure were evaluated by exposing each life stage to the
aerosol and then ... (Click here for full abstract)
Effect of Abiotic Factors on Initiation of Red Flour
Beetle (Coleoptera: Tenebrionidae) Flight
Authors: Perez-Mendoza, Joel; Campbell, James F.; Throne,
James E.
Abstract: Traps baited with pheromones are used
to monitor the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera:
Tenebrionidae), populations in flour mills to aid in making pest management
decisions, but the factors that influence T. castaneum movement are not fully
understood. We investigated the impact of photoperiod, light intensity,
temperature, and relative humidity on flight initiation. The percentage of
adults initiating flight reached a maximum at 30-35°C, and then fell to zero at
22.5 and 45°C. Only 2% of beetles flew in complete darkness,... (

Attract-and-Kill and Other Pheromone-Based Methods
to Suppress Populations of the Indianmeal Moth (Lepidoptera: Pyralidae)
Authors: Campos, Manuel; Phillips, Thomas W.
Abstract: Three attract-and-kill formulations,
a gel, a wax panel, and a plastic cylinder were tested in simulated warehouses
at three densities of devices and at three densities of moths, Plodia
interpunctella Hübner, per room. Wax panels and the cylinder formulations
suppressed all the densities of moths with only one device per room. Two field
experiments were then conducted during 2005 and 2006 in replicated commercial
pet food and grocery ... (

Efficacy of Products to Remove Eggs of Pediculus
humanus capitis (Phthiraptera: Pediculidae) From the Human
Hair
Authors: Lapeere, Hilde; Brochez, Lieve; Verhaeghe, Evelien;
Vander Stichele, Robert H.; Remon, Jean-Paul; Lambert, Jo; Leybaert, Luc
Abstract: Head lice infestations are very
common in children aged between 3 and 12 yr old. The eggs of the head louse are
difficult to remove and remain firmly attached to the hair even after any head
louse treatment. Solid in vitro and in vivo evidence to support the use of any
of the proposed products to facilitate nit removal is scarce. The objective of
the current study was to determine the efficacy of several products to remove
eggshells from human hair ... (

Vacant Lots: Productive Sites for Aedes
(Stegomyia) aegypti (Diptera: Culicidae) in Mérida City,
México
Authors: Baak-Baak, Carlos M.; Arana-Guardia, Roger;
Cigarroa-Toledo, Nohemi; Loroño-Pino, María Alba; Reyes-Solis, Guadalupe;
Machain-Williams, Carlos; Beaty, Barry J.; Eisen, Lars; García-Rejón, Julián E.
Abstract: We assessed the potential for vacant
lots and other nonresidential settings to serve as source environments for
Aedes
(Stegomyia) aegypti (L.) (Diptera: Culicidae) in Mérida City, México.
Mosquito immatures were collected, during November 2011-June 2013, from
residential premises (n = 156 site visits) and nonresidential settings
represented by vacant lots (50), parking lots (18), and streets or sidewalks
(28). Collections totaled 46,025 mosquito immatures of 13 species.
Ae.
aegypti was the most commonly encountered ... (
