We investigated the larval development of the Indian meal moth, Plodia interpunctella, on raw whole almonds, shelled macadamia nuts, shelled walnuts, dried plums, and raisins at various temperatures. Eggs hatched at darkroom temperatures from 15 to 30℃, and adults emerged from all kinds of nuts and dried fruits at darkroom temperatures from 20 to 30℃. There were significant correlations between the developmental period of larvae and rearing temperature. No adults emerged below 15℃, but few larvae survived more than one year at 15℃. These results suggest that nuts and dried fruits should be stored below 10℃ to avoid infestation of P. interpunctella.

Arthropod fauna was studied from July 2012 to July 2013 in three elevator pits in a pharmaceutical factory in Aichi Pref., Japan. In total, 976 arthropods (5 classes; 17 orders; 30 families) were captured with sticky traps placed in the corners of the elevator pits. Arthropods may constantly use the elevator pits as their habitat. Both crawling arthropods and flying insects (5.1%) were captured in the elevator pits. Therefore, those flying insects might use the elevator shafts to travel to other floors. Various arthropods were captured regardless of pit size and season, so elevator pits may have different arthropod fauna and ecosystems even though in the same building.
