  • Transfer of Ingested Insecticides Among Cockroaches: Effects of Active Ingredient, Bait Formulation, and Assay Procedures
    HOUSEHOLD AND STRUCTURAL INSECTS Transfer of Ingested Insecticides Among Cockroaches: Effects of Active Ingredient, Bait Formulation, and Assay Procedures 1 2 1, 3 GRZEGORZ BUCZKOWSKI, ROBERT J. KOPANIC, JR., AND COBY SCHAL J. Econ. Entomol. 94(5): 1229Ð1236(2001) ABSTRACT Foraging cockroaches ingest insecticide baits, translocate them, and can cause mor- tality in untreated cockroaches that contact the foragers or ingest their excretions. Translocation of eight ingested baits by adult male Blattella germanica (L.) was examined in relation to the type of the active ingredient, formulation, and foraging area. Ingested boric acid, chlorpyrifos, Þpronil, and hydramethylnon that were excreted by adults in small dishes killed 100% of Þrst instars within 10 d and Ͼ50% of second instars within 14 d. Residues from these ingested baits were also highly effective on nymphs in larger arenas and killed 16Ð100% of the adults. However, when the baits and dead cockroaches were removed from the large arenas and replaced with new cockroaches, only residues of the slow-acting hydramethylnon killed most of the nymphs and adults, whereas residues of fast acting insecticides (chlorpyrifos and Þpronil) killed fewer nymphs and adults. Excretions from cockroaches that ingested abamectin baits failed to cause signiÞcant mortality in cockroaches that contacted the residues. These results suggest that hydramethylnon is highly effective in these assays because cockroaches that feed on the bait have ample time to return to their shelter and defecate insecticide-laden feces. The relatively high concentration of hydramethylnon in the bait (2.15%) and its apparent stability in the digestive tract and feces probably contribute to the efÞcacy of hydra- methylnon.

PUB TYPE Reports Evaluative (142) EDRS PRICE MF01/PCO2 Plus Postage. DESCRIPTORS Elementary Secondary Education; *Pesticides; *Pests; Poisons; *Public Schools; Surveys IDENTIFIERS *California; *Health Hazards; Policy Issues ABSTRACT This report presents a statewide assessment of pesticides used in California's school system. Of the 46 school districts responding to the statewide survey, 40 claimed using one or more of 27 particularly hazardous pesticides that can cause cancer, affect the reproductive system, mimic the endocrine system, or act as nerve toxins. Forty-three school districts reported routinely using pesticides. The report suggests that not only have California school districts not embraced opportunities for using least-toxic methods to combat pests, but that the state also has no law requiring notification of parents or teachers before applying pesticides in schools. The report recommends: that state policymakers eliminate the use of pesticides that cause cancer; that school managers take the initiative from state agencies to implement reforms; and that teachers, parents, and students request information about pesticides used in and around schools and participate in school pest management decision- making to ensure that least-toxic pest management is practiced.

  • Managing Pests Around the Home Suggestions for the General Public
    Home Pest Control Rev. 2/16 Managing Pests Around the Home Suggestions for the General Public What are household pests? Most household pests are insects that are commonly called "bugs." Other organisms such as spiders, scorpions, centipedes, millipedes, ticks, sowbugs, pillbugs, mites, rats, mice, snakes, bats, squirrels, birds, molds and fungi may enter homes. In Tennessee, one or more of about 40 common pests are found in every home at one time or another. Even the most conscientious person cannot always avoid an occasional pest infestation. Where are these pests found? Under optimal conditions, large populations of an insect, rodent or other pest can occur in your yard, home, farm or neighborhood. Large numbers of a pest species can develop in trees, stumps, flower beds, mulch, leaf litter, garbage, wood piles, ditch banks, animal carcasses, stored products, spilled materials, sewer lines and other sites. Pests enter homes through openings in the walls, floors, around pipes or cracks, under doors or windows. Pests seeking shelter build nests or hibernate within the walls, attic or in living quarters. What attracts them to your home? Pests are attracted by light, warm air, moisture and food. Odors from a dead bird, rodent, dead insects or nest in a wall, soured mop or spilled materials can also be attractive. They seek protection and shelter in dark cavities in walls or crawl spaces. What can I do to prevent pest problems in my home? Luckily, many pests are easily controlled. This publication will explain how to manage the most common household pests found in Tennessee. We have placed special importance on controlling pests by limiting their access to food, water and shelter.

  • How Safe Is Your Bait? Pesticides May Be Labeled
    How Safe Is Your Bait? Pes�cides May Be Labeled as “Nonvola�le,” But S�ll Release Poisons into the Air Editors Note: The issue of vola�lity (chemical evapora�on into the air) is confusing because the classical defini�on of this chemical characteris�c disregards very low level emissions, o�en referred to as “negligible,” that escape into the air. We are aware of vola�lity when we see and/or smell a pes�cide being applied as a spray or aerosol. However, this may not be the case with pes�cides in bait for- mula�ons that are commonly placed throughout buildings in bait sta�ons, or as gels, pastes or granules in cracks and crevices, or behind walls, cabinets, and appliances. While many of the chemical bait products may be characterized as nonvola�le because old technology could not measure the low level vapors, their use may actually result in exposure in indoor environments, par�cularly those areas that are sealed �ghtly. These low level exposures resul�ng from the use of baits have not been evaluated by the regulatory agency, EPA. This piece provides an overview of the pes�cide bait vola�lity issue and reinforces the no�on that the best precau�onary approach is to adopt prac�ces (cultural, mechanical and biological) that prevent insects and rodents from entering structures. Door sweeps, sealing cracks and crevices, moisture control (including proper drainage and dry condi�ons) and sanita�on management all go a long way in reducing the need for chemical products. -- Jay Feldman By Raymond Koytcheff Some baits are contained so as to minimize exposure, and, all else equal, using these baits as part of a targeted treatment is prefer- pen up your local Integrated Pest Management (IPM) able to applying aerosols or sprays over a larger area.

  • German Cockroach Allergen Levels in North Carolina Schools: Comparison of Integrated Pest Management and Conventional Cockroach Control
    FORUM German Cockroach Allergen Levels in North Carolina Schools: Comparison of Integrated Pest Management and Conventional Cockroach Control 1 2 GODFREY NALYANYA, J. CHAD GORE, H. MICHAEL LINKER, AND COBY SCHAL Department of Entomology, Box 7613, North Carolina State University, Raleigh, NC 27695-7613 J. Med. Entomol. 46(3): 420Ð427 (2009) ABSTRACT Cockroach suppression is fundamental to cockroach allergen mitigation in infested homes. The effects of various cockroach control strategies on cockroach populations and allergen concentration have not been examined in schools. This study was conducted to compare the effec- tiveness of integrated pest management (IPM) and conventional pest control in controlling German cockroach (Blattella germanica L.) infestations and concentrations of the cockroach allergen Bla g 1 in public school buildings. Two school districts included six schools that used conventional pest control and one district included seven schools that used IPM to control pests. Cockroach traps were deployed to assess the level of infestation, settled dust samples were collected in food service areas, classrooms, and other school areas, and the Bla g 1 allergen was quantiÞed by ELISA. Both cockroach counts and Bla g 1 concentrations were dependent on the pest control approach, with highly signiÞcant differ- ences between IPM-treated schools and conventionally treated schools in both the cockroach mean trap counts (0 versus 82.6 Ϯ 17.3 cockroaches/trap/wk, respectively) and in the amount of Blag1in dust samples (2.8 Ϯ 0.3 versus 30.6 Ϯ 3.4 U/g dust). Cockroaches and Bla g 1 were primarily associated with food preparation and food service areas and much less with classrooms and ofÞces.

(Dictyoptera: Blattellidae). Coupled gas chromatographic-electroantennographic detection (GC-EAD) and GC-mass spectrometric (MS) analyses of these attractive extracts, or fractions thereof, and of synthetic standards, revealed many candidate semiochemicals. Elaborate olfactometer experiments determined that 1-hexanol from peanut butter, and ethanol and 2,3-dihydro-3,5- dihydroxy-6-methyl-4(H)-pyran-4-one (DDMP) from beer, are the key semiochemicals of these food sources. 1-Hexanol is a well known headspace volatile of decomposing lipids, ethanol conveys food fermentation, and DDMP with a caramel-type flavor has been found in many types of (heated) food.
