“…A compelling argument to account for reduced wasp Þtness through changes in host quality is thermal stress because of production of heat in larval aggregations. For many species of necrophagous calliphorids and sarcophagids, larval aggregations produce heat dependent on species and larval volume, density of the masses, or both, and yield a microclimate with temperatures well above ambient (Campobasso et al 2001, Slone and Gruner 2007, Rivers et al 2010). The elevated temperatures reported under natural or laboratory conditions constitute proteotaxic stress, capable of triggering the heat shock response (Feder 1996, Korsloot et al 2004.…”

Adult females of the ectoparasitoid Nasonia vitripennis (Walker) are capable of distinguishing between hosts of different quality, and then correspondingly adjust clutch sizes and sex ratios of the offspring. In this study, we examined whether the size of the maggot mass, and presumably the developmental temperature, influenced the suitability of the resulting fly pupal and pharate adult stages as hosts for N. vitripennis. Three sizes of maggot masses (100; 500; and 1,000 individuals per mass) were selected for use to generate hosts based on previous studies characterizing developmental and heat shock response differences for the flies. For all host species tested (Lucilia illustris, Protophormia terraenovae, and Sarcophaga bullata), the rate of parasitism by N. vitripennis decreased with increasing maggot mass size. When successful parasitism did occur, parasitoid development increased in duration, clutch sizes decreased, mortality from egg hatch to adult emergence elevated, male biased sex ratios were produced, and adult wasp body sizes were truncated with increasing fly larval density. These wasp life history features are consistent with reductions in host quality. Host quality reductions corresponded to production of heat shock proteins 23, 60, and 70. Heat shock protein synthesis appeared to occur at the expense of normal protein production because total hemolymph protein concentrations decreased with increased larval density in maggot masses. These observations argue that use of N. vitripennis in criminal investigations to estimate periods of insect activity or a minimum post mortem interval must take into account the maggot mass history of the hosts used by the wasp.

“…Greater larval activity leads to increased tissue destruction and the formation of maggot masses in which temperatures up to 20 C higher than the ambient air temperature can be reached [18]. The few larvae on the indoor piglets did not produce such aggregations; so that larvae may develop more slowly indoors than outdoors, even though indoor temperatures were about 2 C warmer than outdoors.…”

“…Slone and Gruner (2008) found several maggot masses formed on each carcass during decomposition, with 67 masses from 29 carcasses in Florida and 17 masses from 12 carcasses in Indiana. Interestingly, 22 of 29 larval aggregations were found in which a single species made up at least 95% of each mass.…”

A central concept in forensic entomology is that arthropod succession on carrion is predictable and can be used to estimate the postmortem interval (PMI) of human remains. However, most studies have reported significant variation in successional patterns, particularly among replicate carcasses, which has complicated estimates of PMIs. Several forensic entomology researchers have proposed that further integration of ecological and evolutionary theory in forensic entomology could help advance the application of succession data for producing PMI estimates. The purpose of this essay is to draw attention to the role of spatial aggregation of arthropods among carrion resources as a potentially important aspect to consider for understanding and predicting the assembly of arthropods on carrion over time. We review ecological literature related to spatial aggregation of arthropods among patchy and ephemeral resources, such as carrion, and when possible integrate these results with published forensic literature. We show that spatial aggregation of arthropods across resources is commonly reported and has been used to provide fundamental insight for understanding regional and local patterns of arthropod diversity and coexistence. Moreover, two suggestions are made for conducting future research. First, because intraspecific aggregation affects species frequency distributions across carcasses, data from replicate carcasses should not be combined, but rather statistically quantified to generate occurrence probabilities. Second, we identify a need for studies that tease apart the degree to which community assembly on carrion is spatially versus temporally structured, which will aid in developing mechanistic hypotheses on the ecological factors shaping community assembly on carcasses.
