“…Among these species, the red-legged ham beetle, N. rufipes , generally found in stored commodities such as copra (dried coconut), cheese, dried fish, ham, and other products rich in protein content, in recent years has caused increasing damage to pet food products, with growing concerns from producers [ 8 , 9 , 10 ]. This pest has a worldwide distribution range, and its occurrence has been recorded in many countries of South, Central, and North America; Europe; Asia; and Oceania [ 9 , 10 , 11 , 12 ].…”

Necrobia rufipes (De Geer) (Coleoptera: Cleridae), also known as the red-legged ham beetle, is a newly emerging pest of pet food stores, causing apprehension among producers worldwide. Concerns about this pest are exacerbated by the lack of information about infestation modalities in pet food, while specific monitoring tools are missing. Considering that adequate pet food packaging could limit N. rufipes infestations, information about the penetration modalities in commonly used pet food packaging is needed. Moreover, the development of appropriate monitoring instruments is urgent to detect pest presence early and to reduce chemical treatments for its control. In this paper, the adults’ and larvae’s ability to enter into pet food packaging was evaluated. Furthermore, to develop monitoring traps, behavioral bioassays were done: (1) testing two different commercial adhesive surfaces, one generally used in mouse glue traps (MG), and the other used in cockroach glue traps (CG), to evaluate their different abilities in avoiding insects’ escape; (2) screening different molecules, typical of the substrates attacked by N. rufipes, as candidate food attractants for this pest: methyl cyclopentenolone (MCP), squalene (SQ), and stearic acid (SA). The results show that N. rufipes adults and larvae enter into packaging through the air vent valves on the bottom, suggesting that a way to improve the packaging to prevent insect infestation would be to modify these points of weakness. Laboratory tests show that the different bioassayed glues have strong differences in the ability to retain the caught insects, with MG being more effective than CG. The behavioral bioassay indicated that MCP and SQ attract N. rufipes adults in olfactometer. Finally, the results of dual-choice arena bioassays show that among the candidate attractant tested, a mixture of pet food (PF) and MCP elicited the strongest attraction in N. rufipes adults. These results encourage further experiments with the use of an MG adhesive trap loaded with a mixture of PF+MCP to test the effectiveness of such a tool for monitoring N.rufipes in pet food industries and warehouses.

Forensic entomology focused sarcosaprophagous insects and arthropods may provide a sound tool for assessment of Post Mortem Interval (PMI) and could provide scientific evidence for date of deaths. However, few data on necrophagous insect are available in many western African countries. The current study focused on Necrobia rufipes, an insect known to be appear on highly decomposed and skeletonized corpses of mammals. Our research aimed at examining some biological parameters of N. rufipes on pig and rabbit used as substrate under ambient conditions. As results, eggs took around 72 hours to hatch regardless substrate. The duration of larval stages was shorter on pigs than those found in rabbits and ranged from 2 to 11 days. Statistical analyses performed showed that substrates had a highly significant effect (P < .0001) on the life span of both adults female and male as well as on female oviposition. The life span of males fed on pig was significantly higher than those fed on rabbit, with values of 74.82 ± 10.34 and 27.55 ± 4.71 days respectively, while for females, the lifespan was 90.36 ± 10.77 and 36.67 ± 4.92 days on pigs and rabbits respectively. Moreover, N. rufipes laid more eggs on pigs ( 285.75 ± 56.94 ) than on rabbits (5.50 ± 1.14 eggs). Pigs remained the most preferred food substrate compared to rabbits and confirmed that they were a good model for forensic investigations. The Knowledge of these parameters could help to get skills for assessing the PMI.

We investigated the effects of various foods and different rearing temperatures on the survival and development of the redlegged ham beetle Necrobia rufipes (De Geer) (Coleoptera: Cleridae), a serious pest of dry-cured hams. The diets tested were dried pet food, finely shredded copra, shredded cheese, dry-cured ham, ground fish meal, and mature larvae of Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). As indicated by the growth index and k-values, N. rufipes populations grew fastest on the pet food and slowest on the copra. On the other hand, N. rufipes fed both ham and T. castaneum larvae produced significantly heavier larvae. The adult beetles lived significantly longer on cheese compared to other foods. Studies conducted to determine the developmental rates of N. rufipes fed pet food at temperatures of 22, 25, 28, and 31°C showed that the total developmental time and longevity of N. rufipes significantly varied at different temperatures tested. The shortest developmental time (93.32 d) was observed at 28°C. Oviposition rate was highest for females reared at 25°C while lowest at 22°C. Based on the development, reproduction, and thermal requirements, the most suitable temperature for N. rufipes was between 28 and 31°C. The results also revealed that larval cannibalism prevailed among adult beetles.
