The ham beetle is the most important of the insects which infest meats which have become dried to some extent by evaporation during long storage or as a result of prolonged smoking. This paper reports the occurrence of Necrobia rufipes (De Geer) (Coleoptera: Cleridae) collected from immature stage of Peckia chrysostoma (Wiedemann) (Diptera: Sarcophagidae) by means of traps containing some fish bait in a forest area close to the Parque da Serra de Caldas Novas, Goiás, Brazil, in the period from August to November, 2003. by coloration and normal amount of hairs, and from fly larvae by found that cross-infestation by N rufipes was reduced when The red-legged ham beetle also attacks bones, hides, copra, dried egg, cheese, guano, bone meal, dried figs, and palm nut kernels. N rufipes is usually found in association with Simple Summary: Necrobia rufipes (Coleoptera: Cleridae) is an emerging pest of pet food stores.

Although refrigeration has reduced the impact of the beetle on meats, they are a significant destructive pest of dried and salt fish including herring. larvae were collected from a floating corpse an d the PMI estimation was approximately three . In this paper, the adults’ and larvae’s ability to enter into pet food packaging was evaluated. The incubation period of eggs was 3.5 days. Females lay up to 30 eggs per day in cracks or crevices of cured fish. 1. jute sacks were lined with polythene and thick brown paper. The adults are surface feeders; the larvae bore into dry or smoked meats and do most damage. Necrobia rufipes (De Greer, 1775) (Coleoptera: Cleridae) is a cosmopolitan pest, and causes considerable damage to store commodities such as copra, cheese, dried fish, ham, and other products that are rich in protein [ 31 ]. The adult is red-brown in color and the larvae are a light honey colour and about. Larvae of the red-legged ham beetle, Necrobia rufipes (Fabricius), were the most tolerant life stages when treated with either phosphine or methyl bromide for 48 h exposure at 23°C, whereas eggs of the mold mite, Tyrophagus putrescentiae (Schrank), were slightly more tolerant than mobile stages for both compounds. In this paper, the adults’ and larvae’s ability to enter into pet food packaging was evaluated. They feed on the meat-infesting larvae of Calliphora or blow flies, Dermestidae and Piophilidae. and 64–70 per cent.
