“…In fact, the absence of such a behavioural response may explain the lack of density-dependent predation and sigmoidal functional response in some study systems where prey are exposed to refuge habitat (e.g. Donnelly and Phillips 2001;Rossi et al 2006;Menezes et al 2006). Yet, because studies rarely marry observations of predator behaviour during a hunting sequence and prey use of refuge habitat with assessment of predation rate across prey density, it is difficult to establish the degree to which prey-centric (e.g.…”

The potential role of prey refuges in stabilizing predator-prey interactions is of longstanding interest to ecologists, but mechanisms underlying a sigmoidal predator functional response remain to be fully elucidated. Authors have disagreed on whether the stabilizing effect of prey refuges is driven by prey- versus predator-centric mechanisms, but to date few studies have married predator and prey behavioural observations to distinguish between these possibilities. We used a dragonfly nymph-tadpole system to study the effect of a structural refuge (leaf litter) on the predator's functional response, and paired this with behavioural observations of both predator and prey. Our study confirmed that hyperbolic (type II) functional responses were characteristic of foraging predators when structural cover was low or absent, whereas the functional response was sigmoidal (type III) when prey were provided with sufficient refuge. Prey activity and refuge use were density independent across cover treatments, thereby eliminating a prey-centric mechanism as being the genesis for density-dependent predation. In contrast, the predator's pursuit length, capture success, and handling time were altered by the amount of structure implying that observed shifts in density-dependent predation likely were related to predator hunting efficiency. Our study advances current theory by revealing that despite fixed-proportion refuge use by prey, presence of a prey refuge can induce density-dependent predation through its effect on predator hunting strategy. Ultimately, responses of predator foraging decisions in response to changes in prey availability and search efficiency may be more important in producing density-dependent predation than the form of prey refuge use.

“…increased temperature and ease of digestion) for larval development. Finally, we also raise the hypothesis that L. sericata could avoid decaying corpses that are colonized by hide beetles [ Dermestes frischii (Kugelann)] because they are predators of dipteran larvae (Menezes et al ., ). To test these hypotheses, in the present study, the volatile organic compounds from decomposing rats are collected under four modalities: (i) in the absence of insects; (ii) in the presence of L. sericata adults; (iii) in the presence of Dermestes frischii adults; (iv) and in the presence of both D. frischii adults and L. sericata adults.…”

Numerous insect species are necrophagous, with Dipterans and Coleopterans being the most abundant on a corpse. Whether the presence of necrophageous species on a corpse affects the attraction of adult blowflies to the corpse is sparsely studied. We test the hypothesis that Lucilia sericata can discriminate the odour of a noncolonized cadaver from the odour of a cadaver on which conspecific and/or heterospecific necrophagous insects are feeding. The volatile organic compounds are collected from decomposing rats under four modalities: (i) in the absence of insects; (ii) in the presence of L. sericata adults; (iii) in the presence of Dermestes frischii adults; (iv) and in the presence of both D. frischii adults and L. sericata adults. During a multiple‐choice bioassay, blowflies are exposed to the four odour samples, and are shown to prefer the odour of a corpse where conspecific larvae are present. We also expect blowflies to avoid cadavers on which predators where present, although L. sericata are not repulsed by the odour of a cadaver colonized by hide beetles. We then compare the average quantities of all 61 volatile molecules identified, finding that the presence of necrophagous insects impacts some of them. However, none of the volatile organic compounds previously reported in the literature as being attractive for L. sericata adults are impacted by the presence of necrophagous insects. The results of the present study suggest that blowfly larvae modify the volatilome of a corpse, enabling adults to discriminate a colonized from a noncolonized corpse.

“…Together with some larder beetles (Dermestidae), such predating behavior could obviously decrease the population of flies breed on corpse. And such predatory pressure could results in an improper estimation of postmortem interval (PMI) after death in forensic investigation based on insect succession fauna data (Kulshrestha and Satpathy 2001;Menezes et al 2006). Additionally, it also does harms to stock food like ham meat or dry fish (Knull 1951;Peck and Thomas 1998).…”

Necrobia ruficollis is a common beetle found on decaying corpse of forensic studies. The complete mitogenome of N. ruficollis was reported in the present study. The mitogenome was 14,443 bp in length totally, with a base composition of 39.4% for A, 10.3% for G, 37.9% for T, and 12.4% for C. The AT content bias was 77.3%. Twenty-two tRNA genes, 13 protein-coding genes (PCGs), and two rRNA genes were anotated. Most of tRNAs could folded into the typical clover-leaf structure, excepte tRNA-Ser (AGN). The result of phylogenetic analyses exhibited that N. ruficollis belong to the family Cleridae. ARTICLE HISTORY
