Technical Abstract: Eight Kansas retail stores belonging to a pet store chain were surveyed during February to August 2001 to determine types and numbers of stored-product insects present, and to identify potential infestation foci. Insects were monitored at 1 to 3 wk intervals using food- and pheromone-baited pitfall traps for beetles and pheromone-baited sticky traps for moths. Thirty traps of each type were placed in a grid fashion within each store. Spatial analysis of trap catch distributions was used to locate infestation foci. Pet food products near the infestation foci were bagged and insects in them enumerated in the laboratory. Thirty-six insect species belonging to 23 families and 7 orders were recorded from the eight stores. The weevils, Sitophilus sp., Indianmeal moth, Plodia interpunctella (Hubner), and the merchant grain beetle, Oryzaephilus mercator (Fauvel) were the most common and abundant species in all stores, whereas red-legged ham beetle, Necrobia rufipes (Degeer), and red flour beetle, Tribolium castaneum (Herbst) were abundant only in one store. Insect abundance varied among stores. Mean pitfall trap catches for beetles ranged from 1.0 to 23.6 adults/trap/wk and from 0.1 to 2.0 larvae/trap/wk. Mean trap catches of P. interpunctella males ranged from 0.7 to 4.0 moths/trap/wk. Insect activity in stores was generally concentrated near shelves of wild bird seeds, shelves of small animal foods, food bar display tables, and stock rooms. All sampled pet food products had insects, and the density ranged from 2 to 2,270 insects/kg. Poor sanitary conditions and lack of effective pest management programs explains the presence, abundance, and distribution of stored-product insects found in these stores.
