  • Effects of House and Landscape Characteristics on the Abundance and Diversity of Perimeter Pests Principal Investigators: Arthur G
    Project Final Report presented to: The Pest Management Foundation Board of Trustees Project Title: Effects of house and landscape characteristics on the abundance and diversity of perimeter pests Principal Investigators: Arthur G. Appel and Xing Ping Hu, Department of Entomology and Plant Pathology, Auburn University Date: June 17, 2019 Executive Summary: The overall goal of this project was to expand and refine our statistical model that estimates Smokybrown cockroach abundance from house and landscape characteristics to include additional species of cockroaches, several species of ants as well as subterranean termites. The model will correlate pest abundance and diversity with house and landscape characteristics. These results could ultimately be used to better treat and prevent perimeter pest infestations. Since the beginning of the period of performance (August 1, 2017), we have hired two new Master’s students, Patrick Thompson and Gökhan Benk, to assist with the project. Both students will obtain degrees in entomology with a specialization in urban entomology with anticipated graduation dates of summer-fall 2019. We have developed and tested several traps designs for rapidly collecting sweet and protein feeding ants, purchased and modified traps for use during a year of trapping, and have identified species of ants, cockroaches, and termites found around homes in Auburn Alabama. House and landscape characteristics have been measured at 62 single-family homes or independent duplexes. These homes range in age from 7 to 61 years and include the most common different types of siding (brick, metal, stone, vinyl, wood), different numbers/types of yard objects (none to >15, including outbuildings, retaining walls, large ornamental rocks, old trees, compost piles, etc.), and different colors.

    THE ECOLOGY AND MANAGEMENT OF THE ORIENTAL COCKROACH Blatta orientalis l.

(ORTHOPTERA: BLATTIDAE) IN THE URBAN ENVIRONMENT by Ellen Mary Thoms Committee Chairman: William H Robinson Entomology (ABSTRACT) The oriental cockroach, Blatta orientalis L., was found to be an important seasonal household pest. Of 151 residents interviewed in two Roanoke apartment complexes in Virginia, 90% had seen oriental cockroaches, 60% considered one oriental cockroach indoors to be a problem, and 77% had taken steps to control these cockroaches. Monitoring oriental cockroach populations indicated when and where treatment would be necessary to reduce cockroach infestations. The adult cockroach population peaked in late June and July, and declined through August and September while the number of nymphs increased. Eighty percent of all cockroaches trapped at Roanoke apartment buildings were caught at porches, the primary cockroach harborage sites. In a mark-recapture study at four apartment buildings, 50% of the resighted oriental cockroaches remained at one porch, 36% moved alc:>ng one side of a building, 13% moved between the front and back of a building, and 2% moved between two buildings. Only 1-5% of the oriental cockroaches marked outdoors were ever captured indoors.

  • Cockroach Control Protocol
    Cockroach Control Protocol Understanding Cockroach Habits and Life Cycle • Cockroaches undergo gradual metamorphosis, passing EGG through three life stages – egg, nymph and adult. ADULT • Nymphs are similar in appearance to adults, but smaller. • As the nymph matures, it sheds its exoskeleton to grow. Freshly molted cockroaches are white, assuming their typical coloration within a few hours as their LIFE CYCLE OF cuticle hardens. THE GERMAN COCKROACH* NYMPH • Each nymphal stage* is larger than the previous one NYMPH and the adult emerges after the last nymphal stage. • The life cycle from egg to adult is dependent upon environmental conditions and the specific cockroach species. Each cockroach species has a unique number of immature stages. • In general, cockroaches need four things to successfully live in an environment: water, food, shelter and warmth. NYMPH Different cockroaches have slightly different requirements, which will be helpful in knowing where to inspect and focus control efforts. *German cockroaches have several nymphal stages (6-7 molts) before becoming adults. Number of molts varies by species. Common Species Inspection • American cockroach, Periplaneta Americana • Locate all harborage sites. Focus on areas where the following conditions exist: high humidity/free water, • Brownbanded cockroach, Supella longipalpa darkness and limited air movement. Look under sinks, refrigerators, dishwashers and stoves, around toilets, near • Smokybrown cockroach, Periplaneta fuliginosa trash containers and inside cabinets and storage areas. See common harborage sites on page 5. • German cockroach, Blattella germanica • Check behind objects attached to walls such as pictures, • Oriental cockroach, Blatta orientalis paintings, smoke detectors and posters. See identifying characteristics on page 3. • Do not restrict inspection to just well-known areas such as kitchens and bathrooms.

However, they are considered pests when they interact with people, invading lawns and gardens or entering homes and other structures. More importantly, they can affect human health by spreading diseases, such as Salmonella, and ruin materials such as books, clothes and food. Cockroaches secrete an oily liquid that has an offensive and sickening odor. This odor may also be imparted to dishes that are apparently clean, food and clothes. Excrement in the form of pellets or an inklike liquid also contributes to this nauseating odor. Additionally, cockroaches produce allergens, which include their feces, shed skins, and body parts such as antennae and legs. In susceptible individuals, contact with these allergens can result in mild to severe rashes, other allergic reactions, and in extreme cases death from asthma attacks.

  • (Blattella Asahinai Mizukubo) in the Urban Environment
    Evaluations of Integrated Pest Management control techniques of the Asian cockroach (Blattella asahinai Mizukubo) in the Urban Environment by Edward Todd Snoddy A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy in Entomology Auburn, Alabama May 6, 2012 Keywords: Invasive species, peridomestic pest, mulch preference Copyright 2012 by Edward Todd Snoddy Approved by Arthur G. Appel, Chair, Professor of Entomology Xing Ping Hu, Professor of Entomology Jack W. Feminella, Professor of Biological Sciences Jeffrey L. Sibley, Barbara and Charles Bohman Professor of Horticulture Abstract The objective of this research was to evaluate components of an Integrated Pest Management (IPM) program for the Asian cockroach, Blattella asahinai Mizukubo. IPM programs are more effective in control of cockroaches than insecticides alone. IPM programs are usually the most environmentally friendly because they drastically reduce the amount of pesticide residue. The toxicity of seven consumer gel and paste insecticide baits was evaluated against Asian cockroaches in continuous exposure tests with and without competitive food. Bait toxicity and consumption varied with the gel and paste bait and with and without a competitive food source. Advion® was the most toxic insecticidal bait, however, and the LT50 value decreased in the presence of competitive food. The toxicity of nine consumer granular insecticide baits was evaluated against Asian cockroaches in continuous exposure tests with and without competitive food. Toxicity and consumption varied among the granular baits and with the presence of competitive food. Most baits had greater LT50 values when the cockroaches were presented competitive food.
