The species Necrobia rufipes (De Geer, 1775) is a beetle of the family Cleridae and is commonly called as red-legged ham beetle as well as the copra beetle. ): Chewing mouthparts Host/s: … According to Nwana, 1993 and Simmons and Ellington (1925) the red-legged ham beetle is a cosmopolitan pest, causing considerable damage to stored commodities such as copra (dried coconut), cheese, dried fish, ham and other products rich in protein content. Necrobia rufipes (De Geer, 1755) (Coleoptera: Cleridae) is an important stored-product species with world-wide distribution. Riley (1874) gave it the common name of red -legged ham beetle, while in the Pacific Island is known as copra beetle (Froggatt, 1911). Saved by Truly Nolen Pest Control. Necrobia rufipes (De Geer) is a beetle, belonging to family Cleridae. Lifecycle. Adult is around 3.5–7 mm in length. It is not a beetle which causes a constant drain on the trade, but occasionally becomes extremely abundant and a great cause of loss. Adult lives up to 3–6 months.

Adult lives up to 14 months. Moreover, it is also a forensically important insect species. The red-legged ham beetle is a cosmopolitan pest, causing significant damage to stored products such as copra (dried coconut), ham, cheese, dried fish and other high protein foods (11, 16). Habits. Commonly feeds on dried copra and other insects that are attracted to mouldy food. In the laboratory we studied the taphonomic marks that Necrobia rufipes (Cleridae) can produce. This study provides data for PMI min estimation using N. rufipes. Flour Beetle (Tribolium castaneum) Appearance. First record of Necrobia rufipes (De Geer, 1775) (Coleoptera; Cleridae) associated with pet food in Brazil Commonly feeds on dried copra and other insects that are attracted to moldy food. Necrobia rufipes, did not make effects so quickly on pig tissue, they were observed after a month. The general life cycle of clerids has been known to last anywhere from 35 days to more than 3 years, ... Necrobia rufipes is attracted towards carrion in the later stages of decomposition, so its arrival on carrion can help provide an estimate for the post-mortem interval or PMI. The complete life cycle of a cheese skipper in appropriate nourishment and temperature conditions can be as short as 12 days (1 day for egg development, 5 day larval maturation, 5 day pupal maturation, 1 day of adult feeding before reproduction). It takes as short as 32 days to complete life cycle. Female lays up to 30 eggs per day in cracks or crevices of cured fish. 3.1 Necrobia Necrobia rufipes is a beetle of the family Cleridae and is the commonest species of Necrobia found on cured fish. The study of the arthropod fauna involved in carcass decomposition is crucial for medicolegal forensic purposes. Recent studies on the infestation of dried fish in Nigeria by Dermestes maculatus and Necrobia rufipes with special reference to the Lake Chad District. The predatory larvae feed mainly on wood- and bark … Two related species, N. ruficollis and N violacea, are only rarely found on this commodity [21]. All the life cycle occurred in the same container. Adult is around 3.5–7 mm in length. The upper surfaces of the body are a shiny metallic bluish-green. The antennae are reddish–brown with a dark brown or black club at the tip. This knowledge is especially needed in countries with high levels of criminality and where the arthropod fauna is still under-recorded and not well known, such as Angola. life-cycle; treatment options; bibliographic references on the information collected for that particular sheet. Binomial name: Necrobia rufipes Common name: Red-legged ham beetle, Necrobia rufipes is a predatory beetle in the family Cleridae with a cosmopolitan distribution. Eggs of this species were detected on Day 2 and only 7 d were needed for completion of its life cycle. Habits. However, the typical life cycle is as follows (Mote 1914): Egg ~23 to 54 hours - Larva ~14 days - Pupa ~12 days - Adult ~3 to 7 days. The complete life cycle of a cheese skipper in appropriate nourishment and temperature conditions can be as short as 12 days (1 day for egg development, 5 day larval maturation, 5 day pupal maturation, 1 day of adult feeding before reproduction). Eggs are laid in crevices or on the rough surfaces of a seed. Habits. Adult is around 3.5–7 mm in length. The adult beetles are 3.5–7.0 millimetres long, convex, straight sided, and the surface has indentations called punctures. Unless a specific institution is credited, the resources on these pages have been developed by members of the Integrated Pest Management Working Group’s Identification Aids Committee. At ideal temperature of 34°C and 70% Relative Humidity (RH), pupation takes up to 3 days. The total life cycle lasts 36-150 days and is highly temperature, humidity and food quality dependent (Anon. At ideal temperature (34°C and 70% RH), life cycle last around 3—4 weeks. It is generally metallic blue in colour but sometimes with a greenish lustre. We made observations and took photographs every 4-5 days for 12 months. Some Trichodes and Hydnocera species are pollen eaters. Trop.Stored Prod.Inf., 29:21-32 . Female produces 200–500 eggs. The life cycle varies from 36 to 150 days or more de-pending on the types of food and temperature. Adult lives up to 14 months. Their legs are bright reddish-brown or orange. 2015). Larval specimens were collected with a forceps and preserved in 70% ethanol. Concerns about this pest are exacerbated by the lack of information about infestation modalities in pet food, while specific monitoring tools are missing. Larva will bore inside the grain to continue growing. Life cycle. Marks were noted after a month. Howe, R.W., 1953. The morphological indexes of larvae were measured in vivo.. Developmental models were established which can be used to estimate PMI min.. A linear discriminant analysis and classifiers for N. rufipes instars were determined.. Necrobia rufipes is known to be a late inhabitant of corpses and feeds on dry cadavers (also on mummies and ham) and probably Case 4: Red Pupae on the Corpse of an Alcoholic on larvae of other arthropods. Female lays up to 30 eggs per day in cracks or crevices of cured fish. Lifecycle. Soil from the bottom of the holes was not sorted through, but was examined visually for any insect life stages. Rearing containers were constructed according to Byrd and Tomberlin (2010).

The specie Necrobia rufipes is commonly known as the copra beetle in tropical countries and red-legged ham beetle in the United States. Riley made the first economic investigation, citing cases of extensive inj ury to hams in St. Louis and Boston (USA). Both larval and adult N. rufipes have been recorded as predators of other stored product pests but are predominantly a pest of stored food, meat and animal products, such as copra, ham, dried fish, and mummies (Lambkin and Khatoon 1990).
