VETERINARY ENTOMOLOGY Mechanical Barrier for Preventing Climbing by Lesser Mealworm (Coleoptera: Tenebrionidae) and Hide Beetle (Coleoptera: Dermestidae) Larvae in Poultry Houses

چکیده
Mechanical barriers consisting of bands of polyethylene terepthalate resin attached to wooden posts by latex caulk adhesive and staples were 100% effective in preventing passage of dispersing lesser mealworm, Alphitobius diaperinus (Panzer), larvae in the laboratory. Barriers continued to be 100%effective after being held in a caged layer poultry house for 3mo. Polyethylene terepthalate barriers installed on support posts in a pullet house inBrooker, FL,were 92%effective against natural populations of lesser mealworm larvae 6 mo after installation. The barriers also were 94%effective against natural populations of larvae of thehidebeetle,DermestesmaculatusDeGeer, when ßy populations were low. Fecal spot depositions by house ßies in excess of 31 cumulative ßy spots per square centimeter on spot cards reduced the effectiveness of the barriers to 79Ð90%, and barrier efÞcacy was reduced to 40Ð56% when ßy spots covered 80% of the surface of the plastic. Washing the barriers with water to remove ßy spots restored their effectiveness against hide beetle larvae to 99%.

متن کاملEvaluation of a barrier to inhibit lesser mealworm (Coleoptera: Tenebrionidae) and dermestidae movement in high-rise, caged-layer poultry facilities.
An evaluation of a mechanical barrier to prevent movement of adult and larval lesser mealworm, Alphitobius diaperinus (Panzer); larder beetle, Dermestes lardarius L.; and hide beetle, Dermestes maculatus De Geer was conducted in caged-layer poultry facilities in New York and Maine. The barrier, a plastic collar wrapped around building support posts, proved highly effective at preventing movemen...
متن کاملExternal surface disinfection of the lesser mealworm (Coleoptera: Tenebrionidae).
Understanding the dynamics of movement of bacteria within the environment and between species is crucial to unraveling the epidemiology of bacterial diseases and to developing biosecurity measures to prevent dissemination. Many arthropods, some beneficial and some detrimental, inhabit poultry houses. The lesser mealworm, Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae), is a pest com...

The lesser mealworm, Alphitobius diaperinus (Panzer), is a carrier of Campylobacter spp. in poultry facilities; however, the beetle's importance in the epidemiology of campylobacteriosis is not known. A series of laboratory experiments were designed to test the vector and reservoir competence of the lesser mealworm for Campylobacter jejuni. In the first experiment, C. jejuni was swabbed onto th...

Dermestes maculatus De Geer (Coleoptera: Dermestidae) is a carrion feeder that is also a pest of poultry houses, museums, silkworm culture, and many stored foods. The Hypocreales, Beauveria bassiana (Balsamo) Vuillemin, Metarhizium anisopliae (Metschnikoff), and Isaria fumosorosea Wize, were tested for efficacy against D. maculatus larvae on concrete, plastic, leather, and wood surfaces. Only w...
